Reading Curriculum for Struggling Readers
Short answer: "struggling reader" is not a curriculum category, and the evidence you are looking for attaches to the method, not to the brand. The federal What Works Clearinghouse practice guide for kindergarten through 3rd grade makes four recommendations, and rates the evidence behind each one. Two carry its top rating of Strong Evidence, and both are about the same thing: "Develop awareness of the segments of sounds in speech and how they link to letters" and "Teach students to decode words, analyze word parts, and write and recognize words."
Reading connected text every day is rated Moderate. That is a checklist you can hold up against any programme on any shelf.
Two things to do before you spend anything. First, ask the school for the evaluation, which is free and is the only step here that can identify a specific difficulty. Second, do not expect the clearinghouse to settle the brand argument for you: on unbranded Orton-Gillingham and on Barton it found no qualifying studies at all, and it says plainly that this means no conclusion either way, not a verdict against them. Every source and its date is at the foot of the page.
What actually carries strong evidence
The guide is "Foundational Skills to Support Reading for Understanding in Kindergarten Through 3rd Grade", released July 2016 and revised December 2019 by the What Works Clearinghouse, which is part of the US Department of Education's Institute of Education Sciences. It lists parents and families among its intended audiences, so this is not a document you need to be a teacher to use.
Here are its four recommendations with the evidence level the reviewers assigned to each, ordered strongest first.
| Recommendation | Evidence level |
|---|---|
| Develop awareness of the segments of sounds in speech and how they link to letters. | Strong |
| Teach students to decode words, analyze word parts, and write and recognize words. | Strong |
| Ensure that each student reads connected text every day to support reading accuracy, fluency, and comprehension. | Moderate |
| Teach students academic language skills, including the use of inferential and narrative language, and vocabulary knowledge. | Minimal |
Read that bottom label before you act on the table. An evidence level describes the body of research the reviewers found and how strong it was. It is not a ranking of how much a skill matters. Recommendation 1 covers vocabulary and academic language and is rated Minimal, and no one sensible concludes from that that a child can read well without vocabulary.
What the ratings are good for is the opposite direction: when two of four recommendations carry the top rating and both are about sounds, letters and decoding, a programme that skips those is skipping the part with the most evidence behind it.
What the clearinghouse says about the brands
Search this topic and almost every commercial result sells an Orton-Gillingham based programme. It is worth knowing exactly what the federal reviewers hold on that, because it is not what either side of the argument tends to claim.
- Unbranded Orton-Gillingham-based interventions, report dated July 2010. Zero studies met the standards. The report states that no studies were found that fell within the scope of its review protocol for students with a specific learning disability and met WWC evidence standards, and that the clearinghouse is "unable to draw any research based conclusions about the effectiveness or ineffectiveness" of them.
- Barton Reading and Spelling System, report dated July 2010. Same outcome, same wording: zero qualifying studies, no conclusion either way.
- Wilson Reading System. This one has a second, earlier review, and it is the most informative of the three. In the Beginning Reading review dated July 2007, one study met the standards. Its findings were split by outcome: potentially positive effects on alphabetics, and no discernible effects on reading fluency or on comprehension. The separate July 2010 review for students with a specific learning disability found no qualifying studies.
Now the part that gets misquoted in both directions. "No study met the standards" is not a finding that a programme fails. The clearinghouse says so itself, in the same sentence, every time. It is a finding about the research, not about the product: the qualifying evidence was not there to review, as of the year on the report. And those years matter, because they are 2007 and 2010. Anyone quoting these findings without the date is presenting old reviews as current ones.
What it does tell a parent is practical. You cannot resolve the brand argument by appealing to the federal clearinghouse, because on these programmes it has not answered the question. The level at which it has answered is the method, which is the table further up this page.
The free step, before you buy any of it
If your child is behind, the first move costs nothing. Under IDEA, a parent has the right to request a free evaluation from their US public school, and schools also carry a Child Find duty to identify, locate and evaluate children who may have a disability. Verified July 24, 2026.
This matters more than the order of operations suggests, because an evaluation is the only step in this whole process that can identify a specific difficulty. No curriculum diagnoses anything. No app or tutoring company does either. Buying a programme before you know what is wrong is how a family ends up owning a decoding programme for a child whose decoding was fine and whose problem was fluency, which our page on what reading fluency actually is goes through in detail.
If the evaluation points toward dyslexia specifically, our page on dyslexia tutoring covers what structured literacy instruction is and how to vet a tutor's credentials.
How to check a curriculum against the evidence
This section is our reading of the recommendations above, not a quotation. The guide rates methods; it does not review the products a parent can buy, so turning its recommendations into shopping questions is our step and we would rather label it than let it pass as sourced.
- Does it teach the sounds explicitly, or assume them? The top-rated recommendation is about awareness of the segments of sounds in speech and how they link to letters. A programme that starts at whole words has skipped it.
- Does it teach word parts, and does the child write as well as read? The other top-rated recommendation names decoding, analysing word parts, and writing and recognising words in one line. Spelling is not a separate subject bolted on later.
- Is there real text to read, every day? The connected-text recommendation is rated Moderate, and it is the one most often reduced to a worksheet pile. Word lists are not connected text.
- Is the sequence fixed, or does the child pick? Both strong recommendations describe teaching in an order. A menu of activities is a library, not a sequence, and a child who is behind is behind at a specific point in that order.
- What does it claim it can diagnose? The honest answer from any product is nothing. A programme that offers to tell you whether your child has dyslexia is telling you something about the seller.
If you are further along than this and comparing actual products, our roundup of reading programs matched to what a child needs works through the ones parents actually buy, and the best phonics programs goes deeper on the decoding half specifically. To place where your child sits before you shop, the reading level chart lines the common systems up against each other, and reading readiness by age maps the earlier milestones to their original sources.
What a curriculum cannot do
Three boundaries worth holding on to, because the marketing on this term does not hold them.
- A curriculum is not an intervention. Materials carry a method, and the method is where the evidence sits. What materials cannot do is watch one particular child and change course. Intervention is instruction delivered by a trained person doing exactly that.
- Nothing in a box identifies a difficulty. Placement tests tell you where to start in that product's own sequence. That is a useful thing and a much smaller thing than an evaluation.
- A child a long way behind is not a shopping problem. The materials are the cheaper half of the answer. The school evaluation, and whatever it entitles the child to, is the half that is free and the half that is difficult to replace.
The federal Regional Educational Laboratory Southeast publishes a free parent resource built directly on this practice guide, "A Resource for Parents and Caring Adults of Children in Grades K-3: Supporting Your Child's Reading at Home", dated May 2026 and written by Marcia Kosanovich, Jennifer L. Dombek and Laurie Lee. It explains the same four skills with activities for home.
We name it rather than link it, and we have not quoted its activities here because those live inside the downloadable document itself.
Where reading tutoring fits, and where it does not
Reading tutoring is the answer to the previous section, not an alternative to it. A curriculum carries a method; it cannot watch one child and change course. That is what a person does, which is why "buy better materials" and "get a tutor" are not two versions of the same decision. The order still holds, though: the free school evaluation comes first, because it is the only step that can name a specific difficulty, and paying for tutoring for reading before you know what is being tutored is how families spend a term on the wrong skill.
Once you do know, the shape of the help follows the finding, and this is where the words get slippery. Reading comprehension tutoring and decoding tutoring are sold under the same label and are not the same job.
- If a child cannot read the words accurately, comprehension tutoring is the wrong purchase. The work is decoding, and it wants a tutor trained in structured literacy, not a general reading tutor. Our page on dyslexia tutoring covers what those credentials look like.
- If a child reads the words but slowly and effortfully, the target is fluency and the tutoring should look like repeated reading of real text, not comprehension worksheets. What reading fluency actually is explains why that distinction changes the whole plan.
- If a child reads accurately and at a reasonable pace but cannot tell you what happened, then a reading comprehension tutor is the right shape, and the useful sessions are the ones spent on background knowledge, vocabulary and talking about text rather than on strategy worksheets.
Comprehension tutoring earns its keep in that third case. In the first two it is a comfortable-sounding purchase that leaves the actual bottleneck untouched, and no amount of it will fix a word-reading problem.
If a school evaluation has already happened and what is missing is simply a person, four questions separate a useful hour from an expensive one, whoever you hire and wherever you find them.
- What is this hour targeting? A tutor who cannot answer in one sentence, naming decoding, fluency or comprehension, is not working from the evaluation.
- What training do they have in that specific thing? For word-reading difficulties this means structured literacy or Orton-Gillingham training, not general teaching experience.
- Has anyone actually checked who they are? On a marketplace, tutors are independent contractors rather than staff, and background screening is usually optional rather than automatic. Whoever you book through, look for what has been verified and by whom, and treat any badge as one input rather than a clearance.
- What happens if it does not work? Ask before the first lesson, not after. Most hourly arrangements refund the first session at best, if anything, and a tutor who does not turn up can still bill under many platforms' rules.
We would rather you spend nothing here than spend it early. If you have not yet asked the school for an evaluation, that request is free, it is a right under IDEA, and it is worth more than any hour you can buy. This page carries no affiliate link, which is the same decision it has always carried.
Frequently asked questions
What reading curriculum is best for a struggling reader?
No source we hold answers that question at the brand level, and the federal clearinghouse that reviews this research has not answered it either. What the What Works Clearinghouse does publish is which teaching methods carry evidence. In its practice guide for kindergarten through 3rd grade, two of four recommendations carry its top rating, and both are about sounds, letters and decoding rather than about any product. So the useful question is not which box to buy, it is whether the box you are looking at teaches those things explicitly.
Is Orton-Gillingham proven to work?
The honest answer has two halves and both matter. In its July 2010 report on unbranded Orton-Gillingham-based interventions, the What Works Clearinghouse found no studies that fell within the scope of its review protocol and met its evidence standards. It then states that it is therefore unable to draw any research based conclusions about the effectiveness or ineffectiveness of those interventions. That is not a finding that the approach fails. It is a finding that the qualifying research was not there to review, as of 2010.
What should I do first if my child is behind in reading?
Ask the school for an evaluation before you buy anything. Under IDEA, a parent has the right to request a free evaluation from their US public school, and schools carry a Child Find duty to identify, locate and evaluate children who may have a disability. It costs nothing, and it is the only step in this whole process that can identify a specific difficulty. No curriculum, app or tutoring company diagnoses anything. Verified July 24, 2026.
Does vocabulary not matter, if it only has minimal evidence?
It matters, and the label is easy to misread. In What Works Clearinghouse practice guides, the evidence level describes the body of research the reviewers found and how strong it was, not how important the skill is. Recommendation 1 covers academic language and vocabulary knowledge and is rated Minimal Evidence, which means the research base supporting that specific recommendation was thin at review time. It does not mean a child can read well without vocabulary.
Can a curriculum replace reading intervention?
Treat them as different things. A curriculum is a set of materials and a sequence. Intervention is instruction delivered by a person who is trained in it, watching one particular child and adjusting. Materials can carry the method, and the method is where the evidence sits, but nothing in a box notices that your child has been guessing from pictures for six weeks. If a child is a long way behind, the materials are the cheaper half of the answer, not the whole of it.
How we reach these conclusions, and the sources behind them, is on our methodology page. The four recommendations and their evidence levels are quoted from the What Works Clearinghouse practice guide "Foundational Skills to Support Reading for Understanding in Kindergarten Through 3rd Grade", released July 2016 and revised December 2019, read from ies.ed.gov and verified August 9, 2026. The findings on unbranded Orton-Gillingham-based interventions and on the Barton Reading and Spelling System, both dated July 2010, and on the Wilson Reading System, dated July 2007 for beginning reading and July 2010 for students with a specific learning disability, are quoted from those programmes' own What Works Clearinghouse intervention pages, read the same day.
Where the clearinghouse found no qualifying studies we state its own conclusion in full, that it is unable to draw a conclusion about effectiveness or ineffectiveness, because the shortened version of that sentence would say something the source does not. The free evaluation right under IDEA and the Child Find duty are attributed to IDEA and were verified July 24, 2026, which is why they carry that date rather than today's.
The section on checking a curriculum is labelled as our reading of the recommendations, not a quotation, because the guide reviews methods and does not review products. Every organisation here is named in text and none is linked. This page carries no affiliate link and that is deliberate: a parent whose child is already behind is exactly the reader we have decided not to sell to, and a page arguing that the evidence attaches to the method rather than the brand has no business carrying a product button. The tutoring section names no company and links to none; it asks the four questions we would ask ourselves.
