Updated: 1 day ago
You have a student who is not responding, a budget conversation coming, and a colleague who has just told you that the program she uses is the one that works. So you go looking for reading intervention programs compared side by side, expecting a table.
What you find instead is a set of pages that put a two-year therapist-delivered curriculum in the same row as a twenty-lesson unit on multisyllabic words, rate both "evidence-based," and leave you exactly where you started.
That is not a failure of research. It is a category problem. The things being compared are not the same kind of object, and the two words used to compare them — evidence-based and accredited — each mean at least four different things depending on who is saying them.
This is a map of what the publishers and the review bodies actually publish, on four axes that can honestly be compared. It does not tell you which program to use with a particular student, and you should be suspicious of anything that does.
It assumes you already know what separates an educational therapist from a learning specialist or an executive function coach, because scope of practice sets the outer limit on which of these programs is yours to deliver at all.
Why the comparison you are looking for does not exist
Line up the programs practitioners actually name and the problem is immediate.
Take Flight, from Scottish Rite for Children, states that it "includes 132 new learning days and 98 application days for a total of 230 days of direct instruction," delivered over two years.
REWARDS, from Voyager Sopris Learning, is "designed to be delivered across 20-25 lessons."
LiPS targets one thing: "the development of an oral-motor, visual, and auditory feedback system that enables all students to prove the identity, number, and order of phonemes in syllables and words."
Those three are not competitors. One is a multi-year comprehensive curriculum, one is a short targeted unit for older students who cannot read long words, and one is a phonemic awareness program. Put them in a comparison table and the table itself is making an argument that is not true.
The International Dyslexia Association says the underlying thing plainly in its own Structured Literacy fact sheet, dated July 2024:
"Structured Literacy is an instructional approach, not a program. However, to deliver this comprehensive instruction, educators often systematically integrate one or more programs."
That sentence is the whole difficulty. The approach is what the evidence base supports. The programs are implementations of it, of wildly different scope, and the evidence attaching to any individual one is much thinner than the field's confidence suggests.
The four axes that can actually be compared
The same discipline that works for executive function assessment instruments works here. Compare programs on facts the publisher or a review body has published, and refuse to compare them on clinical judgement.
Four axes:
What the publisher says it covers — which strands of reading, and whether it is comprehensive or single-strand.
What intensity it specifies — grouping, session length, frequency, total duration, and whether the publisher states these at all.
What you must complete before you may deliver it — training hours, practicum, supervision, and in one case whether you may even buy the materials.
What independent reviewers have and have not evaluated — which is a much smaller set than most program pages imply.
None of those four is a clinical decision. What follows is a decision sequence, not a decision. This article will not tell you which program suits a described presentation, and nothing in it is legal advice.
Axis one: what each program says it covers
The single most useful sort is comprehensive versus single-strand, because it is where practitioners most often mismatch tool to problem.
Single-strand and targeted programs
LiPS (Lindamood Phoneme Sequencing). Phonemic awareness, taught through articulatory feedback. Materials are published by Gander Publishing, which describes the program as developing the capacity to "determine the identity, number, and order of sounds within words." Lindamood-Bell's fact sheet gives a range of PreK to 12 and 80 to 120 lessons.
Seeing Stars. A different Lindamood-Bell program targeting "symbol imagery—the ability to visualize sounds and letters in words," per its program page — orthographic processing rather than phonemic awareness.
Visualizing and Verbalizing. The comprehension-strand sibling, targeting "concept imagery—the ability to create an imaged gestalt from language" (program page).
Read Naturally. Fluency, via a three-component strategy the publisher sets out on its own research page: teacher modeling, in which "a proficient reader models correct reading for a developing reader"; repeated reading, in which "a student reads the story multiple times"; and progress monitoring, in which "the student uses graphs to track his or her performance."
Its stablemates target different strands — Word Warm-ups is phonics, Signs for Sounds is phonics and spelling — so naming "Read Naturally" without naming the product is ambiguous.
REWARDS. Multisyllabic decoding for older students. Voyager Sopris describes it as addressing "word attack skills, vocabulary, fluency, and comprehension" with a focus on "reading long, multisyllabic words," across grades 4 to 12, in 20 to 25 lessons.
Comprehensive curricula
Wilson Reading System. Wilson describes it on its program page as a "Tier 3 Structured Literacy program" that "is based on phonological-coding research and Orton-Gillingham principles," for "All students in Grades 2–12 and adults who are not making sufficient progress in intervention."
Barton Reading & Spelling System. Ten levels, described by the publisher as "An Orton-Gillingham Influenced Simultaneously Multisensory Explicit and Systematic Phonics Program" covering reading, writing and spelling (program description). Barton publishes student entry criteria that most programs do not: at least five years old, in kindergarten or higher, an "IQ of 71 or higher," and a pass on the Barton Student Screening.
S.P.I.R.E. From EPS Learning, for grades PreK to 8 and above, built on "Orton-Gillingham best practices," with a lesson structure the publisher describes as "10 steps that enhance student learning and memory by engaging multisensory pathways" (overview).
Take Flight. Scottish Rite for Children states that "students will learn all 44 sounds of the English language, 96 letter – sound correspondence rules and 87 affixes," across the 230 instructional days above, for "children ages 7 years and older who have developmental dyslexia."
Corrective Reading. McGraw Hill's Direct Instruction program, which is really two programs: a Decoding strand and a Comprehension strand, each with four levels running from 65 to 140 lessons depending on level (program page).
Imagine Sonday System. Formerly Winsor Learning's Sonday System; winsorlearning.com now redirects to Imagine Learning, and the product is branded Imagine Sonday System. System 1 is pitched at "upper elementary and secondary learners with K–2 reading skill levels"; System 2 at students with "3–8th grade reading skills." If you are citing a Sonday implementation study or a district adoption from before the rebrand, note that the publisher of record has changed.
A useful cross-check while you are here: the National Reading Panel named five components — phonemic awareness, phonics, fluency, vocabulary and comprehension. Hold each program against that list and the single-strand ones declare themselves.
Barton and S.P.I.R.E. both tie themselves to Orton-Gillingham, in materially different words, and no organisation adjudicates either claim. If you want to read that wording precisely, here is what “Orton-Gillingham based” actually means, including what the Orton-Gillingham Academy publishes and what the research shows for the category.
Axis two: intensity, and the publishers who do not state it
This is where a comparison table quietly falls apart, because several publishers do not publish the numbers.
Wilson Reading System. "Small group (ideally up to four students), one-to-one." A full lesson is three blocks, with "approximately 30 minutes to complete each Block," and Wilson specifies a "minimum of two complete lessons per week." Wilson does not publish a total program duration.
Barton. "The maximum group size allowed with the Barton System is three-on-one," and "You must provide at least 2 hours of one-on-one tutoring each and every week" (FAQ).
Take Flight. "Take Flight is designed for small group instruction (two to six students) for a minimum of 45 minutes per day, five days each week. Alternatively, the lessons can be taught for 60 minutes each day for four days a week."
LiPS. The fact sheet splits by tier: groups of five to eight at 30 to 45 minutes for Tier 2; groups of five or fewer at 60 to 120 minutes for Tier 3 and special education.
S.P.I.R.E. A "45-minute, teacher-led lesson structure," usable one-to-one or in small groups. Weekly frequency is not stated.
Corrective Reading. McGraw Hill's decoding-strand introduction specifies "35–45 minutes of teacher-directed work and independent student applications" in daily lessons. Group size is not given a number on the publisher's own pages.
REWARDS. The publisher's overview page states the number of lessons and the grade band and gives no session length, no weekly frequency and no group size at all. Session parameters quoted in secondary writing about REWARDS come from individual research studies, not from Voyager Sopris.
So the honest intensity comparison is partial. Two of the programs most often placed side by side — REWARDS and Corrective Reading — cannot be compared on group size using publisher sources, and one of them publishes no session parameters whatsoever. That absence is worth knowing before you build a service delivery model around a number you found on somebody's blog.
The intensity table everyone wants cannot be built from published sources. Several publishers simply do not state the numbers, and the numbers circulating in secondary writing are study parameters wearing a publisher's name.
Axis three: what it takes before you may deliver it
Here the programs differ more than on any other axis — and the spread has nothing to do with the strength of the evidence behind them.
At one end, Barton. Its tutors page states that "Becoming a Barton Tutor requires no degree or teaching experience" and that the qualifying test is "Anyone who can pass our 5-minute Tutor Screening."
What Barton does gate is sequence rather than credential, and it is unusually blunt about it: "No one – not even someone with a Ph.D. in Reading Instruction – can take over tutoring for a Barton Student in Level 5." Certification exists but is optional: "Certification is optional, but Certified Barton tutors can charge higher rates," across three tiers covering levels 1–3, 4–6 and 7–10.
A step along, S.P.I.R.E., whose professional learning page opens with "You can begin teaching with our Orton-Gillingham–based programs in as little as one day." Imagine Learning makes a similar claim for the Sonday System — implementation "after just one interactive, hands-on training day."
Then Wilson, which is a different order of commitment. WRS Level I certification requires a 90-hour online course, then "1:1 WRS instruction with a practicum student for a minimum of 65 lessons with a lesson plan written for each lesson," and to "Be observed five times teaching the practicum student," each observation lasting "approximately 60–75 minutes."
Pre- and post-testing is required "with two norm-referenced tests, one being the Word Identification and Spelling Test (WIST)."
Wilson also constrains the practicum student: in or entering grades 4–12 with grade 3 approved on retention, "Overall cognitive ability in average range (minimum IQ = 80)," and "Overall reading must be ranked in the 5th to 30th percentile with a minimum total reading score of grade 2.0." Level II adds four further components including two practica of 75 minimum instruction hours each.
And at the far end, Take Flight, which gates the materials themselves. Scottish Rite's educators and trainers page states: "Only *Take Flight*-trained therapists can purchase the *Take Flight* materials." Its Academic Language Therapist track runs two years, including sixteen summer weekdays in year one, four school-year seminars and five video demonstrations, with a shorter Dyslexia Practitioner track and a ten-day Certified Teacher track alongside it.
Line those up and the range runs from a five-minute screening to a two-year therapist training — and none of it is predicted by what the review bodies have found. Barton and Wilson, as the next section shows, carry the identical sentence from the What Works Clearinghouse.
Whatever the program says, the AET Code of Ethics binds independently. Clause II.I.E requires members to "select and use appropriate instructional methods, curricula, materials, and other resources," and I.II.A to "provide only those professional services for which they have been adequately trained" (Code of Ethics, Revision #9, 2025). A publisher's willingness to sell you a kit after a one-day workshop does not discharge that.
Axis four: "evidence-based" is at least four different claims
This is the part that repays slowing down, because four distinct systems are in circulation and they are routinely conflated on the same page.
1. The NCII tools chart rates studies, not programs
The National Center on Intensive Intervention's Academic Intervention Tools Chart is the source practitioners most often treat as a shortlist. It is not one, and NCII says so repeatedly.
From the chart's own resource page:
"The presence of a particular program on the chart does not constitute endorsement and should not be viewed as a recommendation from either the TRC on Academic Intervention or NCII."
From the Tools Charts User's Guide, three sentences that ought to be better known:
"The study quality ratings reflect an assessment of the quality and technical rigor of a research study. They do not say anything about the results of the study; they do not present any assessment of whether the study provided evidence of program effectiveness."
"Note, the tools chart provides ratings on individual studies of programs, not holistic ratings of the programs themselves."
"The charts are not intended to endorse any program or tool, or to compare programs or tools to one another."
The rating vocabulary is "convincing, partially convincing, unconvincing, or data unavailable," applied across dimensions including design, participants, fidelity of implementation, measures and effect size. A green bubble beside a program means a study about it was well conducted. It does not mean the study found anything.
There is a second, quieter point about the chart. Several of the best-known structured literacy programs were not found on it when this article was researched on 13 August 2026 — searches of the chart returned no entry for Wilson Reading System, Barton, S.P.I.R.E., Take Flight or LiPS, while two other Lindamood-Bell programs, Seeing Stars and Visualizing and Verbalizing, do appear.
The chart is a JavaScript table that resists exhaustive enumeration, so treat that as "not found on the date checked" rather than a proven absence. Either way, absence from the chart means only that no qualifying study has been submitted and reviewed.
2. WWC intervention reports rate programs, in six grades, mostly a long time ago
The What Works Clearinghouse rates named programs, using the effectiveness vocabulary set out in its Procedures Handbook: positive effects, potentially positive effects, no discernible effects, mixed effects, potentially negative effects, negative effects — each paired with an "extent of evidence" that is either small or medium to large.
What it has actually found about the programs in this article:
Wilson Reading System, Beginning Reading, 2 July 2007. One of nine reviewed studies met standards. "The WWC found the modified version of the Wilson Reading System® used in this study to have potentially positive effects on alphabetics and no discernible effects on fluency and comprehension." Extent of evidence small in all three domains; the qualifying study covered 71 third-grade students. Report.
Wilson Reading System, Students with Learning Disabilities, July 2010. No studies met standards. "The lack of studies meeting WWC evidence standards means that, at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of the Wilson Reading System® on students with learning disabilities." Report.
Barton Reading & Spelling System, Students with Learning Disabilities, July 2010. "None of the 13 studies meet WWC evidence standards with or without reservations," followed by the identical conclusion sentence. Report.
Read Naturally, Beginning Reading, updated July 2013. "Read Naturally® was found to have potentially positive effects on general reading achievement, mixed effects on reading fluency, and no discernible effects on alphabetics and comprehension for beginning readers." Report.
LiPS, Beginning Reading, updated November 2015. "LiPS® was found to have potentially positive effects on comprehension and mixed effects on alphabetics for beginning readers," extent of evidence small in both domains. Report.
Corrective Reading, Adolescent Literacy, September 2010. One of 13 eligible studies met standards. "Corrective Reading was found to have no discernible effects on the alphabetics, reading fluency, and comprehension domains for adolescent learners." Snapshot.
REWARDS, Take Flight, S.P.I.R.E., Sonday System. No WWC intervention report was found for any of these as of 13 August 2026.
Read that list honestly and three things follow. The reports are old — the most recent here is more than a decade past. Most rest on a single qualifying study. And the two programs most widely used by educational therapists, Wilson and Barton, both carry the same July 2010 sentence saying the WWC could reach no conclusion either way.
That is not evidence that these programs do not work. It is evidence that the program-level research base is thin, and that a practitioner who says "the research supports Wilson" is usually reaching past what the research says. What the evidence supports strongly is a set of *practices*, which is the next system.
Wilson and Barton — the two programs most educational therapists have on the shelf — carry the identical 2010 sentence: the WWC "is unable to draw any conclusions based on research about the effectiveness or ineffectiveness."
3. WWC practice guides rate practices, not products
The strongest evidence in this field attaches to instructional practices, and the two current IES practice guides are the place to find it.
Providing Reading Interventions for Students in Grades 4–9, March 2022, carries four recommendations:
"Build students' decoding skills so they can read complex multisyllabic words" — Strong Evidence
"Provide purposeful fluency-building activities to help students read effortlessly" — Strong Evidence
"Routinely use a set of comprehension-building practices to help students make sense of the text" — Strong Evidence
"Provide students with opportunities to practice making sense of stretch text (i.e., challenging text) that will expose them to complex ideas and information" — Moderate Evidence
For the earlier grades, Assisting Students Struggling with Reading: Response to Intervention (RtI) and Multi-Tier Intervention in the Primary Grades, February 2009, covers kindergarten to grade 3 and remains live, with no archival notice.
Its recommendations carry mixed ratings as displayed on the current WWC site: universal screening twice a year at Moderate; differentiated reading instruction at Minimal; "Provide intensive, systematic instruction on up to three foundational reading skills in small groups to students who score below the benchmark score on universal screening" at Strong; "Monitor the progress of tier 2 students at least once a month" at Minimal; and daily tier 3 instruction at Minimal.
Note that the 2009 PDF and the current site label the lowest tier differently — "low" in the printed guide, "minimal" on the site. Quote whichever you are looking at, and do not upgrade it.
The two guides are companions covering different grade bands, not a replacement of one by the other.
4. Publisher alignment claims, which are claims about the third system
Once you have the practice guides in view, publisher marketing reads differently. Voyager Sopris states that "*REWARDS* is the only reading intervention on the market perfectly aligned to recently released national IES Practice Guide recommendations for teachers."
That is a claim about alignment to a document that rates practices, not a claim that the WWC has evaluated REWARDS — and, as noted above, no WWC intervention report for REWARDS was found. EPS Learning's S.P.I.R.E. pages carry an "ESSA Approved" badge, which points at a fourth framework again: the evidence tiers in the Every Student Succeeds Act, which are not the WWC's ratings and not NCII's.
Four systems, four vocabularies, one adjective. When a program page says "evidence-based," the useful next question is always: evidence of what, rated by whom, in what year, on how many studies?
Accreditation: two lists, and they barely overlap
The second word that does not mean one thing is accredited.
IDA accredits educator preparation programs. Not curricula. Its accreditation handbook sets out two levels — Accreditation, and Accreditation PLUS for programs preparing candidates "to provide targeted or intensive reading interventions." Of the packaged curricula discussed here, exactly one organisation appears on IDA's accredited teacher training programs list: Wilson Language Training, at Accreditation PLUS.
Checked 13 August 2026, the strings "Take Flight," "Scottish Rite," "Sonday," "S.P.I.R.E.," "SPIRE," "Barton," "Lindamood" and "LiPS" do not appear on that page at all. Also on it, and worth noticing: the Orton-Gillingham Academy, Neuhaus Education Center, the National Institute for Learning Development, and IMSLEC itself.
IMSLEC accredits courses. From its about page: IMSLEC "accredits quality Multisensory Structured Language Education (MSLE) training courses." Its public directory lists dozens of accredited providers, and Scottish Rite for Children — Take Flight's home — sits on it at Therapy and Instructor level. Scottish Rite states the linkage directly: "Scottish Rite's Academic Language Therapist training is accredited by The International Multi-Structured English Language Education Council (IMSLEC)."
So the two most rigorous training pathways in this article sit on two different accreditation lists, and neither appears on the other's. Wilson is IDA-accredited and makes no IMSLEC claim anywhere we could find. Scottish Rite is IMSLEC-accredited and does not appear on IDA's list. Barton, S.P.I.R.E., Sonday and LiPS appear on neither, as of the date checked.
State this carefully when you repeat it. Absence from an accreditation list is not a judgement about a program — it usually means the organisation has not applied, and both bodies accredit *training*, never the curriculum in the box.
If you are mapping how these credentials relate to the ones you already hold, the learning specialist certification landscape covers the individual credentials, and the continuing education map covers which of these bodies will accept the other's hours.
State lists are not the shortcut they look like
Practitioners in states with dyslexia legislation often assume there is an approved program list to defer to. Sometimes there is; often there is not, and the ones that exist say less than expected.
Texas's Dyslexia Handbook, in its 2024 update, names no approved commercial programs. It sets out instructional criteria and separately names certifying bodies — the Academic Language Therapy Association, the International Dyslexia Association, the Orton-Gillingham Academy and Wilson Language Training — without endorsing a curriculum.
Louisiana's A Guide to Dyslexia in Louisiana, August 2024, similarly requires a multisensory structured language program meeting stated components and leaves selection to districts and IEP teams. Arkansas does maintain an approved science of reading curriculum list, referenced in Commissioner's Memo LS-21-032 of 9 November 2020.
Two states named as publishing no program list and one as maintaining one. That is a three-state observation and nothing more — it is not a fifty-state finding, and this is not legal advice. Your state's requirements are a question for your state education agency, and questions about independent practice belong with an attorney.
Where the published record runs out
Every comparison of these programs has gaps. Most articles hide them. Here are the ones found while researching this piece, so you know exactly where to stop trusting the table.
The NCII chart could not be exhaustively enumerated. It is a JavaScript data table that truncates when fetched. Programs reported above as "not found" are not proven absent.
REWARDS publishes no session length, weekly frequency or group size. Any such figure you see attributed to REWARDS is a study parameter, not a publisher specification.
Corrective Reading's group size is not published by McGraw Hill. The "small groups" description in circulation comes from third-party summaries.
Barton's own two pages disagree on training hours. The homepage describes three to five hours of streaming tutor training per level; the FAQ refers to six hours per level. Both are Barton's statements and neither is obviously the correction of the other.
S.P.I.R.E.'s level count is inconsistent. The scope-and-sequence document shows Foundations plus Levels 1–5; the overview page refers to seven instructional levels.
Take Flight does not use the term "CALT." Secondary writing routinely says Take Flight requires a Certified Academic Language Therapist. Scottish Rite's educators page names three provider tiers — Academic Language Therapist, Dyslexia Practitioner and Certified Teacher — and the strings "Certified Academic Language Therapist," "CALT," "therapist-in-training" and "ALTA" do not appear on it. The requirement that is published is narrower and more concrete: only Take Flight-trained therapists may purchase the materials.
Wilson publishes no total program duration, which makes any claim about "how long Wilson takes" someone's estimate.
The Sonday System's delivery figures live on a legacy support subdomain that predates the Imagine Learning rebrand and may be superseded.
IDA's Structured Literacy fact sheet exists in more than one wording. The July 2024 PDF and IDA's web page on Structured Literacy give overlapping but not identical definitions and element lists. Cite the one you actually read.
None of that makes the programs worse. It makes the comparison harder than it is usually presented, and a practitioner who knows where the record stops is better placed than one working from a tidy table that quietly filled the gaps.
A decision sequence, not a decision
You will notice this article has not told you which program to use. That is deliberate, and it is the same boundary that applies to choosing assessment instruments: the sequence is publishable, the decision is clinical and belongs to you and the student's team.
The sequence that follows from the four axes:
1. Establish what the deficit actually is before shopping. A phonemic awareness gap, a decoding gap in multisyllabic words, and a fluency ceiling are three different problems, and three of the programs above address exactly one of them each. Your initial screening and baseline data and written plan come first, not the catalogue.
2. Sort the candidates by scope. Rule out single-strand programs for a comprehensive need, and rule out multi-year curricula for a narrow one, before comparing anything else.
3. Check the intensity you can actually deliver. Two 45-minute sessions a week does not run Take Flight. If the program specifies a frequency you cannot meet, it is not a candidate, whatever its evidence.
4. Check the gate, honestly. Not whether you can buy the materials, but whether you have completed what the publisher specifies and what AET I.II.A requires. A one-day workshop is a real qualification for a program designed around a one-day workshop, and not a qualification for one designed around a 65-lesson practicum.
5. Read what the reviewers actually said, in the original, with the date and the study count attached — not the publisher's summary of it.
6. Write down your decision rules before you start, so that "this is not working" is a data question rather than an argument in month five. NCII's decision rules are the standard reference: four data points above the goal line means consider raising the goal, four below means consider adapting the intervention.
That last step is the one that most often gets skipped, and it is the one that makes the program choice recoverable if it turns out to be wrong.
Frequently asked questions
Which reading intervention program has the strongest evidence?
Asked at the program level, the honest answer is that no program in this comparison has a strong current WWC rating from a substantial evidence base. The strongest evidence attaches to practices rather than products — the 2022 IES guide rates decoding instruction for multisyllabic words, fluency-building activities and comprehension-building practices as Strong Evidence, and those recommendations are program-agnostic.
Is Orton-Gillingham itself evidence-based?
Orton-Gillingham is an approach rather than a program, and the same distinction IDA draws about Structured Literacy applies: "Structured Literacy is an instructional approach, not a program." Several programs describe themselves as Orton-Gillingham based or influenced — Wilson, Barton, S.P.I.R.E. and Sonday all do — and their published evidence differs from one another despite the shared lineage.
Do I need certification to use a reading intervention program?
It depends entirely on the program, and the range is wide. Barton states that becoming a tutor "requires no degree or teaching experience." Take Flight materials cannot be purchased at all except by trained therapists. Wilson requires a 90-hour course plus a 65-lesson supervised practicum for Level I certification. Separately from any publisher requirement, AET clause I.II.A requires members to provide only those services for which they have been adequately trained.
What is the difference between the NCII tools chart and the What Works Clearinghouse?
NCII's Academic Intervention Tools Chart rates individual studies for methodological quality and explicitly states that its ratings "do not say anything about the results of the study." The WWC rates named programs on effectiveness, in six grades, with an extent-of-evidence qualifier. A program can appear on one, both or neither, and appearing on the NCII chart is not a finding that it works.
Is Barton or Wilson better?
Neither the WWC nor, as far as could be verified, any other independent reviewer has published a finding that would answer that. Both carry the same July 2010 WWC conclusion that no research-based conclusion could be drawn about effectiveness or ineffectiveness on students with learning disabilities.
They differ enormously on scope, on intensity, on what you must complete to deliver them, and on accreditation — Wilson Language Training is on IDA's accredited list and Barton is not — and those are the differences you can actually reason about.
Does my state have an approved list of dyslexia programs?
Some states do and some do not, and it must be checked state by state. Texas's 2024 Dyslexia Handbook names no approved commercial programs; Louisiana's August 2024 guide leaves selection to districts and IEP teams; Arkansas references a maintained approved curriculum list. Nothing here is a fifty-state finding, and your state education agency is the authority on your own requirements.
The short version
Reading intervention programs cannot be ranked against one another from published sources, because they are not the same kind of object and because the evidence attaching to any single one is thinner and older than the field talks as though it is.
What can be compared is scope, published intensity, the training gate, and what named reviewers actually said and when. Those four are enough to shortlist honestly — and honest is the most a comparison can be here.
