I've just been given my son's first set of CAT scores in Year 4. He is dyslexic and out of cohort (July baby, held him back an academic year so he started Reception at 5 not 4).
My understanding is that the CAT is a raw score which is then calculated against the child's age and compared to the national average for an identically aged child (in my son's case that would be 9.2 at time of test). However, given that an average 9.2 year old is in Year 5 and thus has had an extra year in school, how accurate is the CAT in his situation do you think?
School seem perplexed by my raising the question. Maybe I'm not understanding correctly but it seems potentially inaccurate to compare him to someone who might be chronologically the same age, but who has spent an extra year in school?
Obviously it is all rather muddied by the dyslexia but he's scoring bang on average Quant/Spatial. A little above NVR and fairly high VR.
Love any wisdom from others with a child out of cohort or from anyone who knows about CATs! thank you!
