What a cognitive profile can tell you, and what it cannot

A profile comes back with four rows on it, each one a shaded range instead of a score, and the question in almost every house is the same: fine, but what is his IQ. There is no IQ on the page and there never will be. The reason is worth more to you than the number would have been.

The four abilities, in words you can use at home

• Verbal reasoning. Working out relationships between words: which of five does not belong with the other four, how one pair maps onto another. A wide vocabulary and weak verbal reasoning turn up together often enough that the two should not be confused. This ability sits under law, and under any degree where a student reads four hundred pages a week.
• Quantitative reasoning. Reasoning about number and quantity: analogies, series, the rule that generates the next term. Distinct from Maths marks, which reward two years of teaching as much as they reward reasoning. A student can hold a top band here and a middling Maths mark, usually after a bad year or a bad teacher.
• Non verbal reasoning. The same pattern work with the words taken out: shapes, matrices, sequences. Because it leans on neither English nor what a school covered, a student whose language is holding their marks down often scores higher here than anywhere else.
• Spatial reasoning. Holding an object in your head and turning it, working out what it becomes. No school subject in Classes 8 to 10 puts a mark against this, so a student can be in the top band and reach seventeen without one teacher mentioning it. It matters for engineering drawing, for stereochemistry, and for the eighty marks of offline drawing in Part A of NATA.

Why you get a band and not a number

Every measurement carries error. Test the same student on a different morning, after a different night's sleep, and the result moves. A band is that uncertainty made visible: a range wide enough to cover where the student's true position probably sits, against others of the same age, on this set of tasks. A student at the top of stanine 5 and one at the bottom of stanine 6 are the same student, whatever the boundary implies.

Spiky is normal, level is the unusual one

Families brace for the spiky profile: one ability well above the rest, one below, two sitting in the middle. It is the ordinary result. Four bands lying level is the rare one, and it tells you considerably less.

Read the size of the gap rather than the fact of it. A single band sits inside the error and means nothing, while a gap of three or four stanines, holding across both subtests of a battery rather than resting on one bad five minutes, describes something real.

A spike is not a diagnosis, and a low band is not a finding of dyslexia or dyscalculia. Nobody can make that call from a forty minute online test, ours included. Where a large gap matches what a class teacher has been saying for two years, take both to a qualified professional.

The claims to walk away from

An IQ score. CAT4 style batteries report stanines, bands and percentiles, never IQ. IQ figures come from clinical instruments given one to one by trained psychologists, and no group reasoning test converts into one. If a report prints IQ 118 across the top, whoever produced it used a different instrument or invented the number.

Learning styles. The claim that your son is a visual learner and needs diagrams, that your daughter is auditory and needs things explained aloud. Researchers have put VARK and the wider learning styles family through trial after trial for thirty years, and it fails every time: matching teaching to a stated style does not improve what a student learns. Where it appears on a report, you have learned something about the company.

A career. No set of reasoning tasks produces the sentence "your daughter should be a corporate lawyer". What a person ends up doing depends on interest, on what the family can pay for, on who they meet at nineteen, and on fifteen years of work not yet done.

A type. Anything telling you what your child is: a colour, four letters, an animal, a half of the brain. Reasoning develops, and a Class 8 profile is a photograph rather than a verdict.

The two things it is worth the hour for

The first is catching a mismatch between how a student reasons and what that student is being pushed towards. A boy in a two year JEE programme whose quantitative and spatial bands sit well below his verbal band is not incapable of the course. He will carry more load through it than the boy beside him for the same marks, and his parents deserve to know that before they pay the first year's fees. The reverse arrives as often, a student steered into Commerce after one bad Maths year while sitting in the top band for quantitative reasoning. We work that choice through in how to choose between PCM, PCB and Commerce.

The second is finding a strength nobody had looked for. Spatial is the usual one, and most families hear about it for the first time when the child is already sixteen. Verbal is the other, and it changes the conversation in a house that assumed engineering by default, because CLAT is settled by reading more than by anything a student memorises.

What it cannot see

A reasoning battery cannot see effort. It has nothing to say about character or motivation, or whether a student will sit down at seven every evening for two years without being asked. Those matter more to a Class 12 result than any band on the page.

Prior attainment remains the strongest single predictor of later academic outcomes anyone has measured. When Geiser and Santelices followed roughly eighty thousand students through university, school grades beat every admissions test in the study. Marks carry effort and consistency mixed together, and no cognitive profile competes with that. Read the two side by side. Where they disagree, the disagreement is the part worth an argument at the dinner table. More on that in what Class 10 marks can and cannot decide.

Pace changes the instrument

One honest caveat about our own product. A whole year group sits a battery like CAT4 in one hall against one tightly standardised clock, and its bands come from a sample who sat it under those conditions. Where a profile runs slower, and ours sets the pace by the class sitting it, you are measuring something adjacent: reasoning with the time pressure lifted out.

That is often the reading a family wants for a thirteen year old who freezes against a clock, and it is not the same reading. A stanine from a slower sitting and a stanine from CAT4 are not interchangeable, so lining the two up in one column is a comparison worth nothing.

Whether you need one at all

Plenty of families do not. If the subject marks point one way, if the student gives the same answer on two different days when nobody is standing over them, and if the school's comments match, you will pay to be told what you already hold. Spend the money on a tutor instead. We would rather say so here than after you have paid.

It earns the hour when the evidence disagrees with itself: strong marks from a student who cannot explain a thing he scored on, a stated interest nobody in the house believes, a subject settled two years ago that the student is quietly sinking in.

IRIS is our version of this: four kinds of reasoning across eight short subtests, roughly forty minutes, every result printed as a range, and no fix sold on the back of it. Where a family wants that reasoning read alongside interests and personality, PRISM does that instead. Both are allowed to come back with a level, unremarkable profile and nothing to act on.
