Dyslexia vs Poor Reading Instruction

Missed teaching or dyslexia?

Some things can look like dyslexia from across the table. Reading that was never taught step by step can look the same. If that is the only cause, the trouble is in the teaching, not the child. To us, that is a question about the method, not about any teacher.

The International Dyslexia Association (IDA) wrote a new definition in 2025. The IDA's definition says the trouble lasts even with teaching that works for other children their age. It does not say for how long.

We hold no study that measures teaching quality as a cause of dyslexia. No study we hold tests home signs for telling dyslexia from missed teaching.

What tutoring studies found

One study tutored young children who were behind in reading (Vellutino and colleagues, 1996). Some caught up quickly, and some did not. An education research database sums the study up. It calls the tutoring a step toward telling two kinds of trouble apart. One kind came from too little reading experience. The other came from weaknesses underneath. That summary is the database's, not the authors' own.

Later work by the same team looked at IQ scores (Vellutino, Scanlon and Lyon, 2000). We could read only its summary. In that work, some children were easy to help. Others were hard to help. IQ scores did not tell the two groups apart. One review listed IQ among things that predicted gains (Nelson, Benner and Gonzalez, 2003). We could read only that review's summary.

Those findings are about groups of children, not a promise about yours. They are not a reason to wait and see. No study we have tests wait-and-see as a plan for a learning difficulty. So we would not tell you to wait.

When extra help is not working

In our view, ask what will change in the help, not just the time.

One article lists ways to make extra help stronger (Fuchs, Fuchs and Malone, 2017). They include a closer match to what the child is missing. They also include changing the help as the child's progress is checked. That is a list of ideas, not a trial. We could read only a short description of it.

One trial looked at young children who gained little from help (Wanzek and Vaughn, 2008). Some then got a single amount of extra help. Some got a double amount, and some got none. Over time, the single and double amounts did about the same. More children who got help made faster progress than children who got none. We could read only its summary. Those findings are about groups of children, not a promise about yours.

Teaching now, either way

In our view, teaching the missing skills now is worth doing either way. Find which job of reading is going wrong, and work on that one. The exception is a skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.

Ask the school whether its phonics teaching is systematic and explicit.

Our page on whether it is dyslexia or something else covers the rest.

When to ask for help

Each of these is a reason to ask for help on its own.

• Little change, even with steady practice and good teaching.
• Reading well below what school expects.
• A teacher who raises a concern about reading.
• Extreme upset about reading.
• Complete avoidance of reading.
• Hopelessness about learning.
• Sadness or worry that lasts.
• Significant delays in speech, language or motor development.
• A skill that was there and has gone. Our position is that a lost skill goes to a doctor first, not a tutor.

If no skill has gone, start with the teacher. Say what you are seeing at home, and what you have tried. Beyond the teacher, the right person depends on what it turns out to be about. If the work is too hard, someone who works on that school skill. If worry or mood is the thing, someone who works with children's mental health. In our view, delays in speech, language or movement are worth raising with your child's doctor. In our view, if you are worried enough to ask, a professional evaluation is worth asking about.

Any talk of hurting themselves is a same-day call to your doctor or a crisis line.
