The WASI is a screening, not an actual IQ test. You would need to do the entire WISC - IV not just portions to get WISC IV results. As it is a screening, IQ scores may or may not reflect scores on the WASI. Some kids do really well on it and not on the WISC IV because it tests some different things than the WISC IV. Vice versa, some kids score better on the WISC IV as it appeals more to their strengths.
The MAP, CogAT, ITBS also are not IQ tests but more achievement tests. These are not accepted for DYS.
