Standardised Assessments, Explained
You will be handed a report with numbers in it. Most families are never told what those numbers actually mean, how much they can be trusted, or what they cannot tell you. This page explains all three before you book, not after.
A diagram of how standard scores are distributed. It contains no patient data.
A score is a range, not a number
Every score in every report comes with a margin of error. A good report prints it. A good clinician talks about it.
No test measures a child perfectly. Attention wanders, a question is misheard, a lucky guess lands. So the honest way to report a result is not “your child scored 92” but “your child’s true ability is very likely somewhere between about 87 and 97” — which is what a confidence interval means.
This matters enormously in practice, because it is the difference between two scores being genuinely different and merely looking different. If two ranges overlap, the gap between them is not something to build a decision on — and yet decisions get built on exactly that, every day, in schools and in clinics.
If a report you have been given anywhere shows single numbers with no ranges attached, that is worth asking about.
The single headline number is the least useful part
Two children can produce the identical overall score and need completely different things. The overall number is an average, and averaging is exactly the operation that hides the thing you came to find out.
Illustrative profiles. These are not real results, and the subtest names are examples of the kind of areas a battery covers.
What can move a score on the day
A test measures how a child performed in one room, on one morning, with one adult they had just met. Several ordinary things push that performance away from the child’s actual ability — and almost all of them push it downwards.
The one that matters most here, and gets said least
Most standardised tests were normed on children somewhere else. A standard score compares your child to the sample the test was built on — and for the majority of internationally used batteries, that sample was not Egyptian and was not tested in Arabic.
That does not make the tests useless. Used carefully they are still by far the best structured way to compare a child’s own areas against each other, to track change over time, and to give a school something concrete. But it does mean a single number carries less weight here than the report format implies, and anyone treating it as a hard fact about your child is overreading it.
In practice: we test in the language the child is strongest in wherever the tool allows, we say in the report which norms were used, and we weight the profile and the observations more heavily than the headline figure. If someone gives you a number without any of that context, ask.
What testing can and cannot answer
Families usually arrive with a question rather than a request for a particular test. Some of those questions are exactly what standardised assessment is for. Others are not, and no amount of testing will produce the answer — which is worth knowing before you pay for a battery that was never going to tell you.
| The question you arrived with | Testing? | What actually answers it |
|---|---|---|
| “Why is my bright child failing at school?” | Yes | This is the classic case for a full battery — an uneven profile is exactly what explains the mismatch. |
| “Does my child have a learning difficulty?” | Yes | Cognitive and academic testing together, plus school evidence over time. Neither on its own is enough. |
| “Is my child gifted?” | Yes | Testing answers this reasonably well — though the useful output is the profile, not a certificate. |
| “Does my child have autism?” | Not alone | A diagnostic assessment: structured observation, developmental history and clinical judgement. Cognitive testing informs it but does not decide it. |
| “Does my child have ADHD?” | Not alone | Evidence from more than one setting, rating scales, history and a clinical assessment. No single test result diagnoses it. |
| “Why is my child so anxious or angry?” | Rarely | Clinical assessment with a psychologist. Testing may contribute if a hidden learning difficulty is driving it. |
| “What will my child be able to do at eighteen?” | No | Nothing answers this. Scores in early childhood are weak predictors of adult outcomes, and anyone forecasting from one is guessing. |
How we handle the limits
What you can hold us to
- Ranges, not points. Confidence intervals appear in the report and are explained in the feedback session, not buried in an appendix.
- The norms are named. The report says which test, which edition and which normative sample — so anyone reading it later knows what the comparison actually was.
- Language is recorded. Which language testing was carried out in, and whether that is your child’s stronger one, goes in the report because it changes how the numbers should be read.
- We will say when a score looks wrong. If a child was unwell, distressed or clearly not engaging, that goes in the report and the result is treated as provisional rather than quietly filed.
- No re-testing too soon. Repeating the same battery within a short window inflates scores through practice. If someone offers to re-test quickly for a better number, that is not a favour.
- A feedback session, always. A report posted to you without someone walking you through it is a document, not an assessment. You should leave able to explain your own child’s results to a teacher.
Assessment & psychology
Administering a test is the straightforward part. Interpreting a profile, weighing it against everything else known about a child, and saying honestly what it does not show — that is the part that needs a clinician.

Assessment, answered plainly
Will this give my child a label?
Standardised testing on its own does not produce a diagnosis. It produces a profile of strengths and difficulties. Whether that profile forms part of a diagnostic picture is a separate clinical decision, made with history and observation, and you will be told clearly which of the two you are getting.
Can my child fail?
No, and it is worth saying that to them in those words before they come. Tests are built so that every child meets items that are too hard for them — that is how the range is found. A child who found some of it difficult did not do badly; they did what the test was designed to make happen.
Should I prepare my child, or practise?
Prepare them, do not practise. Tell them where they are going, that it is puzzles and questions and talking, that some bits get hard on purpose, and that nobody is being marked. Practising on similar materials makes the result less accurate, not better.
My child speaks Arabic and English. Which is used?
Whichever they are genuinely stronger in, wherever the tool allows it, and the choice goes in the report. Testing a bilingual child in their weaker language reliably underestimates them, and reports that do not mention language leave the next reader unable to judge that.
We were tested elsewhere. Can you just re-do it?
Usually the better first step is to bring the old report. Repeating the same battery too soon inflates the result through practice, and a second opinion often turns out to be about interpretation rather than administration — which does not need a new test at all.
How long does it take, and do I stay?
It is spread across the session with breaks, because a tired child produces a misleading score. Parents are usually not in the room during testing itself — children perform differently when a parent is watching — but the history and the feedback are entirely with you.
Will the school accept the report?
We write reports so that they are usable: what was administered, what the scores mean, what they do not mean, and specific recommendations rather than general ones. Whether a particular school acts on it is outside our control, but a vague report guarantees they will not.
How often should assessment be repeated?
Only when there is a reason — a decision to make, a stage change, or a clear mismatch between the last report and what is now being seen. Routine re-testing on a fixed schedule mostly generates practice effects and paperwork.
Come with the question, not the test name
The first appointment establishes what you actually need to know and whether standardised assessment is the way to find it out. Sometimes it is; sometimes the honest answer is that something else will tell you more.

All scores, profiles and ranges shown on this page are illustrative diagrams used to explain how standardised assessment works. They contain no patient data and are not examples of any child’s results. Standardised tests compare a child with the normative sample the test was built on, which for most internationally used batteries was not collected in Egypt; results are interpreted with that limitation in mind. Assessment, interpretation and any recommendation are decided individually by the treating clinician. In an emergency, call 123 or go to the nearest emergency department immediately.
