The RIAS-2 includes a two-subtest Verbal Intelligence Index (VIX), a two-subtest Nonverbal Intelligence Index (NIX), and a Composite Intelligence Index (CIX), created by combining the VIX and NIX scores. This internal memorandum was submitted to the Exceptional Children Director to demonstrate that the RIAS was fully compliant with federal regulations requiring that all evaluations be both reliable and valid for the purpose for which they were being used. CIX reliability is reported to be about .97; the reliability for the FSIQ on the WISC IV was reported to be about .98; reliability for GAI on the WISC IV was reported to be .96.
