Pediatric Developmental Evaluations: How to Read the Report and Use It
You leave with a document full of numbers that were explained once, quickly, while you were still processing the first paragraph. Here is what each part of it actually means.
Pediatric developmental evaluations end with a document, and most families read it properly for the first time at home, days after the appointment where it was explained. By then the explanation has faded and what is left is a stack of numbers with unfamiliar names.
This is a guide to reading that document. It applies to a report from us, from a school, or from anyone else, and our evaluations page covers what the appointment itself involves.
The numbers in pediatric developmental evaluations, and which ones to trust
Three kinds of number turn up, and they are not equally useful.
Standard scores compare your child against the average for their age. On most tests, 100 is dead average and roughly two thirds of children fall between 85 and 115. A score of 92 is unremarkable. A score of 68 is a long way from the middle. This is the number to look at first.
Percentiles say the same thing differently: what share of children the same age scored below your child. The 50th percentile is average. Percentiles are easy to read and easy to over-read, because the ones near the middle are crowded together. The distance between the 40th and 60th percentile is small in real terms, while the distance between the 2nd and the 10th is substantial.
Age equivalents say your four year old is performing like an average child of two years nine months. They are the number parents remember and the number clinicians trust least. They are not evenly spaced, they exaggerate small differences at younger ages, and they invite a comparison that the test was never designed to support. Treat them as the loosest figure in the document.
One more thing worth knowing: every score has a margin of error, and good reports say so. A number is a snapshot of one child on one morning, not a fixed property of them.
The part that actually matters
It is not the scores. It is the section describing what the clinician observed.
Two children can produce an identical standard score for completely different reasons, and the plan for them is different. A test result tells you where a child sits relative to peers. The observations tell you what is actually going on: whether they gave up quickly, whether they understood the instruction, whether they could do it with a bit of help, what they did when it got hard.
If you read one part of a report closely, read that one. If it is thin, ask for more.
Why does my child’s score look worse than they seem at home?
This is the most common reaction to a report and it usually has a good explanation.
A test is a snapshot taken in an unfamiliar room, with a stranger, on demand, at a time of day chosen by a scheduling system rather than by your child. Almost every child performs below their true ceiling under those conditions, and some perform a long way below it.
There is also a difference between what a child can do and what a child can do when asked. A four year old who names every animal in a book at home may say nothing when handed a card by someone they met ten minutes ago. That is not the test failing, and it is not your child failing either. It is information about how they handle demand, which is worth knowing.
The reverse happens too. Some children present better in a quiet room with one adult and no siblings than they ever do at home, and a report can come back reassuring while your ordinary week is still difficult.
This is exactly why the observation section matters more than the numbers, and why a good clinician asks whether what they saw looked typical for your child. If nobody asked you that, tell them anyway.
What the recommendations should look like
Recommendations are the operational half of the document and they are often the weakest.
A useful recommendation names something observable, in a setting, with a rough sense of when you would know. Not improve expressive language, but use two word combinations to request during everyday routines. You should be able to picture it happening in your kitchen.
A recommendation should also say what happens if it does not work. Reports that only describe a plan and never describe a review point are common, and a plan with no review point tends to run on quietly for a year.
Ask for anything you cannot picture to be rewritten. This is a normal request and a good clinician will not mind.
Watch for recommendations that are really referrals in disguise. Consider an audiology assessment, discuss with your pediatrician, seek a diagnostic opinion: each of those is somebody else’s job, and each needs an owner and a date or it quietly becomes nobody’s. Before you leave, work out which recommendations you are responsible for actioning and which the clinic is.
What this report is not
A therapy evaluation is not a diagnostic assessment, and the distinction matters more than any number in it.
We do not perform diagnostic autism testing. That is a separate process, carried out by a psychologist, a developmental pediatrician or a diagnostic team, answering a different question with different tools. If a report from us describes your child’s communication, motor skills or sensory responses in detail, that is useful evidence for whoever carries out a diagnostic assessment, and it is not a substitute for one.
The two can run in parallel. A therapy evaluation does not wait on anyone else’s assessment, and families frequently start therapy while a diagnostic referral is still in a queue. If that is the situation you are in, say so and we will make sure the report is written to be useful to the next person who reads it.
What to do in the first week
A report is easiest to act on while the appointment is still fresh, and hardest once it has been in a drawer for a month.
Read it once quickly and once slowly, a day apart. The second reading catches things the first one skims, because the first reading is mostly emotional and there is no way around that.
Write your questions down as you go, including the ones that feel too basic to ask. What does this word mean is a perfectly good question and clinicians would far rather answer it than have you guess.
Decide who else needs a copy. Your pediatrician usually should have one. The school may. A daycare or preschool sometimes benefits, though think about what you want them to do with it before you send it.
Then put one thing into practice. Not all of it. The recommendation you can picture most clearly, started this week, is worth more than a complete plan you mean to begin properly in the new year.
Using it at school
A private report does not automatically produce a service at school, and knowing that in advance saves a difficult meeting.
School eligibility is decided by the school team against educational criteria, which are not the same as clinical ones. A child can have a clear clinical finding and still not qualify, because the question the school is answering is whether the difficulty affects access to education.
What a report does well is put something specific on the record and make it harder to dismiss a concern as parental worry. To get the most out of it: send it in advance rather than producing it in the room, ask for it to be entered into the record, point at the specific findings you want addressed rather than handing over twenty pages, and put any request in writing.
If you disagree with the school’s own evaluation, you have the right to request an independent one at public expense, which is worth knowing before you pay privately for a second opinion.
Questions worth asking before you leave
Most families think of these in the car. Ask them in the room.
- What is the single most important thing in this report?
- What would you expect to change first, and roughly when?
- What would tell us this is not working?
- Which of these recommendations is for me, which is for the school, and which is for a doctor?
- Is there anything you could not assess today that we should come back for?
And if the report arrives later by email, read it within a week while the appointment is fresh, and send your questions then rather than waiting for the next visit. If anything in a report of ours does not make sense, ask us and we will go through it with you.
Common questions
What is the difference between a standard score and a percentile?
They describe the same result two ways. A standard score compares your child to the average for their age on a scale where 100 is typical. A percentile says what share of children the same age scored lower. A standard score of 100 sits at the 50th percentile, and both mean squarely average.
Why does the report avoid giving an age equivalent?
Because age equivalents are the least reliable number in the document and the easiest to misread. They can make a small difference sound alarming, and they are not evenly spaced, so the gap between two of them means different things at different ages. Some clinicians include them reluctantly and some leave them out.
The school did its own evaluation and got different results. Who is right?
Often both. Different tests measure different things, a child performs differently on different days and in different rooms, and school eligibility uses criteria that are not the same as clinical ones. Bring both reports to the conversation rather than choosing between them.
How long is the report good for?
Roughly a year for most purposes, and less for a young child who is changing quickly. Schools and insurers often set their own limits. If you are heading into a meeting with a report over a year old, ask whether the report needs updating before rather than after.
