A teacher or a doctor said a word about your child. You had to look it up later. Dyslexia, maybe. Or dysgraphia, dyspraxia or dyscalculia. They all start the same way, and they blur together. You are not the only parent who has searched these words at midnight.
Common questions from parents
What is the difference between dyslexia and dysgraphia?
Is dyspraxia the same as dysgraphia?
If my child struggles with one of these, will the others follow?
Does a learning difference mean my child is less smart?
How do I get my child evaluated?
Dyslexia, dyscalculia, dysgraphia, dyspraxia. Four words that sound alike and point at four different skills. Here is how to tell them apart.
What does each of these four words point at?
Each word points at a different kind of hard. Here is what the infographic shows, in plain words.
- Dyslexia: reading and spelling. Words are hard to read and to spell. Trouble with the sounds in words is part of it for many children. The International Dyslexia Association calls that “common but not universal.”
- Dyscalculia: number sense. How big a number is, and how many. Number facts. Telling time and handling money. Here is how number sense shows up in time and schedules.
- Dysgraphia: writing. Forming letters. Getting thoughts onto the page at a steady pace. People use this word in more than one way. Ask what they mean by it.
- Dyspraxia: planning movement. Coordination, and doing movements in the right order. It shows up in handwriting and in PE. Doctors also call it developmental coordination disorder, or DCD.
The image adds two more truths. These struggles overlap. And none of them measures how smart a child is.
A label is a starting point. It is not the plan.

Why do these struggles so often show up together?
Some children have more than one of these. The infographic is right that overlap is normal. It is not a pile of separate disasters. But it is not a rule, either.
A big Dutch twin study (van Bergen, 2025) looked at reading, math and attention. A child who struggled in one area was more likely to struggle in another. But most of the children who struggled did so in only one area. Where the line is drawn also changes how much overlap you see (Moll, 2014).
So watch your own child, not a list of what might come next. Here is what to know when one struggle seems to lead to another.
The second truth matters too. None of these four words is a measure of intelligence. Struggling to read says nothing about how smart your child is. The two were never the same thing. In 2025, the International Dyslexia Association dropped an old line from its definition. That line had compared reading to other thinking skills. The paper explaining the change says IQ-gap methods “lack predictive validity” (Catts, 2026).
Key takeaways
- Four words, four skills: Each word points at a different kind of hard: reading, numbers, writing or movement.
- Overlap is real, not a rule: One struggle makes another more likely, but not certain.
- Your words come first: A plain description of what is hard tells everyone what to teach.
How do you get help that fits your child’s struggle?
A label is a starting point. It is not the plan. A diagnosis describes where your child is today. It does not predict where they’ll be in a year of the right kind of practice.
The same struggle on paper might come from different places. Take a child whose writing is hard. The hard part might be spelling the words. It might be forming the letters. It might be planning the hand movements. Each one calls for different teaching.
That is why your plain words matter. Here is what to do first.
- Write down what you see. Use plain words, not labels. Note what is hard, when it happens and what helps.
- Ask which skills were checked. Sounding out words, number sense, handwriting speed or coordination. Ask about each one by name.
- Question a label that does not fit. If it does not explain everything you see, ask what else was looked at.
- Ask for an evaluation in writing. In the US, a parent can ask the school district directly. It is free to the family. Keep a dated copy.
Only a professional evaluation can get formal supports, like an IEP or 504 plan. Bring your notes to it. They help the right questions get asked.
Try this tonight. Fold a page in half. On one side, write what is hard. On the other side, write what comes easily.
“Writing difficulties do not necessarily reflect poor motor skills, as writing also involves cognitive, orthographic and spelling skills.” SpLD Assessment Standards Committee (SASC), 2020
Struggling to read says nothing about how smart your child is. The two were never the same thing.

You don’t need a credential to be your child’s first teacher. You already are one. Too many families get a word, then a wait, and no plan. The free Learning Difficulties Analysis asks about more than one area at once. It asks what you see at home; it does not diagnose.

Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
