Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Wechsler subtest ceilings

I would ask DYS directly because I suspect that they may accept the WASI FSIQ because it is calculated from the same four subtests as the GAI on WISC-IV, although the GAI usually includes two additional subtests. Unless everything has completely changed, the four subtests used in WASI are Matrix Reasoning, Block Design, Similarities and Vocabulary, which are the subtests to calculate the PRI and VCI indices. My oldest DS took the WASI once and the WISC-IV many times and that is what the testers told me. It is possible that I could be wrong if they completely changed the WASI in the last few years but I have not heard this.

If DYS won't accept the WASI FSIQ as equivalent to WISC GAI, then I personally would probably not choose the MAP scores as one of the portfolio items because while the scores are certainly high, they may not be DYS high (if that makes sense).
