CATs are Cognitive Assessment Tests.
There are different ones:
Quantitative - this covers numbers skills and maths reasoning.
Verbal - this covers language and vocabulary
Non-Verbal - this covers reasoning, patterns and other aspects that require no knowledge of language or number skills.
These tests are standardised so take age into account (if that is unclear, a simple idea is to imagine the children were all tested on their 9th birthday - which is, of course, impossible so everyone takes the tests on the same day and then they are standardised to account for the age differences.)
Generally, the 'average' score is between 85 and 115. Anything outside of those limits is highlighted, so a score of 132 is well above average.
In most cases CATs simply give an idea of current cognitive ability. As a SENCo I used to analyse the tests, paying attention to any children who had particularly spread scores. For example, if your DC has all scores in the above average range then she is a bright child who is working to her ability. If her non-verbal score is the 132, then it is interesting to see whether her others are also in this range - if not, she may not be working to her ability so may be under achieving or there may be specific learning difficulties that are hindering her learning. If her non-verbal is lower and this 132 is for verbal or quantitative then she is working hard and achieving very well.
Please note, all of this is simply indicative and will be taken into consideration alongside a huge number of other formal and teacher assessments.
I hope this makes sense - I am sure the teacher will be happy to answer any queries you have, even in her pregnant state (I have recently been there!)or feel free to ask me.
Well done to your DD anyway!
