What is the correlation between CAT and IQ scores such as Wechsler Intelligence Scale for Children (WISC) used by educational psychologists?
In general, we find a high correlation between the CAT Verbal and Non-Verbal batteries and the WISC Verbal and Performance IQ respectively. Also, experimental work carried out in collaboration with the University of Sheffield in 2004 made it possible to equate CAT scores on one test with scores on the WISC, so that in psychological or clinical assessment of children, either test could be used to estimate performance on the other one.
