Our mission
They corrected the definition in 2025. Nobody told the parents.
In 2025 the International Dyslexia Association rewrote its definition of dyslexia for the first time in 23 years. It dropped the IQ gate that turned bright children away from help. It acknowledged that the causes run across several systems, not one. It named the anxiety and the lost confidence. It said early support works best. Every word of that correction is welcome. Every word of it arrived 23 years late.

The definition that stood from 2002 until last year described dyslexia as a language-based learning disability, and the field read that narrowly — one system, one story, one fix. It carried an IQ-discrepancy model, which in practice meant a capable child who struggled to read was told the gap between their intelligence and their reading was not wide enough to qualify for help. It said nothing about the anxiety that grows around years of failing at something everyone else appears to find ordinary. It said nothing about timing, so schools heard permission to wait.
The 2025 definition corrects all four. Causes are now described as complex — genetic, neurobiological and environmental influences combined. Overall cognitive ability is explicitly ruled out as the source. Psychological well-being, including anxiety, low self-esteem and mood, sits inside the definition itself. And early language and literacy support is named as particularly effective, which is the polite way of saying that wait-and-see was wrong the entire time it was standard advice.
Not one of those corrections required a discovery. The evidence was published, peer-reviewed and sitting in plain sight for years before the wording moved. The science was never the bottleneck. The distance between what researchers knew and what a parent was told across a classroom table — that was the bottleneck, and it ran 23 years wide.
So let us say the part that matters most first. If you drilled the phonics and it plateaued, you were not failing your child. If you waited because someone with a title told you to wait, you were not being passive. You were following the map you were handed. The map was wrong. That is not the same thing, and you are owed the difference.
The receipts
Anger without dates is a complaint. Here are the dates.

2002–2025
The definition itself
For 23 years the field’s own definition carried an IQ-discrepancy model. A bright child who struggled to read was told, in effect, that the distance between their intelligence and their reading was not wide enough to qualify for support. The 2025 definition removes that gate: reading difficulty is explicitly decoupled from overall cognitive ability. The children turned away between those two dates are adults now.
23 years -
2008
Learning styles
Researchers tested whether matching instruction to a child’s “learning style” improves learning. It does not. That finding was established in 2008 and independently reconfirmed as recently as 2024. A 2020 review of educators across 18 countries found nearly 9 in 10 still believe in it. That is not a science problem. It is a systems problem, and it has been running for most of two decades.
17 years and counting -
2019
Teaching children to guess
Eye-tracking research established long ago that skilled readers process nearly every letter and lean more heavily on letter-sound information as they improve. Guessing a word from the picture beside it is what struggling readers do — one cognitive scientist describes the three-cueing method as a description of how poor readers read. It took a national investigative podcast in 2019 to move any of this into public view, and states were still passing corrective reading laws in 2024 and 2025.
A program that teaches a child to guess words from pictures is not teaching them to read. It is teaching them to look like they are reading.
Decades, then a podcast -
Today
“Wait and see”
The 2025 definition says early support is particularly effective. Meanwhile the road to formal help still opens with an intervention period — often 60 to 90 days — that runs before a special-education evaluation begins, followed by the evaluation window itself (commonly around 60 days, though states vary), followed by meetings. A family that starts asking in September is fortunate to hold a plan by spring. Every month of that is another month of a child deciding what kind of learner they are. Parents are entitled to put an evaluation request in writing at any point, and few are told so.
Still standard advice -
Ongoing
The evidence behind what families were sold
This part has to be said precisely, because the precision is the point. The largest independent synthesis of Orton-Gillingham reading interventions (2021, Exceptional Children) found effects that were positive but not statistically significant for foundational reading skills or for comprehension. The flagship program marketed for children with learning disabilities has no study qualifying at the federal What Works Clearinghouse in that population — the clearinghouse was unable to draw any conclusions. For one of the most widely used home and tutoring programs, zero of 13 studies examined qualified. And the umbrella review of brain training found little evidence that training improves distantly related tasks or everyday performance: you get better at the game, not at life.
None of that proves those programs fail. It means no study survived a rigorous independent screen — a statement about evidence quality, and we hold ourselves to phrasing it that way. What earns the anger is the marketing layer built on top. There is no official ESSA certifying body; “ESSA tiers” are evidence standards, not awards. Publishers hire commercial research firms that both run the study and issue the badge. One publisher’s paid evaluator awarded a “Moderate” rating; the independent Johns Hopkins registry, reviewing the same studies, rated it one tier lower. Families make five-figure decisions on those badges — clinic instruction runs roughly $90 to $110 an hour, and a six-week intensive commonly passes $10,000.
Ask who paid
The bill did not go to the institutions
Children with learning differences carry more anxiety, more depressive symptoms and lower self-esteem than their peers — a pattern documented across dyslexia, dyscalculia, dysgraphia and attention differences. Around 30% of children with a specific learning disorder also show behavioural or emotional difficulties. Study after study traces it to the same place: not the wiring, but the accumulated experience of failing in public at something everyone else appears to find ordinary.
We will not claim the old definition caused that. The research is correlational, and we say so. What we will say is this: 23 years of telling children to try harder at a task resting on a skill nobody had checked produced a generation who reached a simpler and far more permanent conclusion — that they were stupid. That conclusion is the injury. It outlasts the reading gap by decades. The 2025 definition finally names it, inside the definition itself, one year ago.
“I’m bad at reading” isn’t a description of where your child is. It’s a prediction your child is making about where they’re going — and every session is either confirming it or quietly rewriting it.
So here is what we are correcting
- Correct the record in public, with dates. Publish the myths and the evidence underneath them, so a parent walks into a school meeting holding the same receipts we do. Nothing on this page is proprietary. Take it with you.
- Change the sentence, not the child. A diagnosis describes where a child is today. It does not predict where they will be after a year of the right kind of practice. Your child isn’t broken — their brain is learning differently.
- Check every system, not the famous one. Phonics is necessary. It was never sufficient. Reading leans on visual processing, auditory processing, working memory and processing speed at the same time, and the bottleneck is rarely the one everyone has heard of. Treat phonics as the whole answer and you get a child who sounds out words and still does not read.
- Put the parent back in the driver’s seat. The 2025 definition places environmental influences, the home among them, inside the causes. Parent involvement stopped being supplemental the moment that sentence was published. Nobody will ever advocate for your child as hard as you will.
- Take cost out of the gate. A clinic intensive runs into five figures. Whether a family gets a clear picture of how their child learns should never turn on what they earn. That is why this work sits under a nonprofit foundation.
What we will not say
A page this angry earns nothing without limits. Here are ours, published, so they stay checkable.
- That a screener beats a professional diagnosis. It does not. A screener is a starting point, not a diagnosis. If your child might need formal accommodations — an IEP or a 504 plan — or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
- That a diagnosis harms your child. The research runs both ways, and for many children a name for the struggle brings genuine relief. The label was never the lever. The framing wrapped around it is.
- That IEPs are the enemy. Done well, accommodations measurably help. The question was never “accommodation: yes or no.” It is “is this support building the skill, or replacing the expectation that it gets built?”
- That your child’s struggle is a gift. Real strengths often come out of it — earned through the struggle, not handed over in place of it. We will not paper over how hard it is.
- Numbers we made up. If we cite it, it carries a name, a date and a source you are free to check. Where the evidence is thin, we say thin.
The most useful question in this entire field is who paid for the study. Ask it of the program in the glossy brochure. Ask it of the badge on the box. Ask it of us. A large independent trial of one of the biggest names in this field publishes around 2027 and 2028, and we will report what it finds either way. A standard applied selectively is not a standard.
The correction is a year old. The advice has not changed.
Somewhere today a parent is being told to wait and see. Somewhere a bright child is being told they are not behind enough to qualify. Somewhere a family is paying five figures for a program whose evidence never survived an independent screen. None of that stopped in 2025. It stopped being defensible in 2025, which is not the same thing — and the difference is being paid for by children right now.
You need no diagnosis, no label and nobody’s permission to start. Find out which systems your child’s learning actually rests on, and build from there.

Fair questions
Isn’t this simply another program claiming everyone else is wrong?
A fair question, and here is the test we would apply in your position. We publish what we refuse to claim. We cite independent referees — the federal What Works Clearinghouse, the Johns Hopkins registry — rather than studies we commissioned about ourselves. We name the evidence class of our own field rather than hiding inside it. And we tell you to ask who funded the research, including ours. Hold us to all four.
The definition changed. Does that alter anything for my child today?
Three things. The IQ gate is gone, so “bright enough to cope” is no longer a reason to be turned away. Causation is multi-system, so a program aimed at one system is no longer a complete answer. And early support is named as particularly effective, which makes “wait and see” the advice to push back on rather than follow.
My child already has a diagnosis. Is this page telling me that was a mistake?
No. A diagnosis opens doors that nothing else opens, and for plenty of children it ends years of self-blame. Our argument is about what gets said next. A diagnosis describes where your child is today; it does not predict where they will be after a year of the right kind of practice.
Do I need a diagnosis before starting?
No. Skills are built without a label, and the sooner the right ones are targeted, the better. If your child might need formal accommodations, or you suspect a vision, hearing or medical cause, pursue a professional evaluation alongside — a screener is a starting point, not a diagnosis.
