For the heart of the test, the primary index scores, the subtests take less time (about 10 minutes) to administer than the WISC–IV. The FSIQ can be obtained about 25–30 minutes faster than the WISC–IV. Because the age ranges of the WISC–V and the WAIS–IV overlap for examinees aged 16, practitioners have the option of choosing the appropriate measure for an examinee this age. For examinees suspected of below average cognitive ability, the WISC–V should be administered because of its lower floor at this age range. Table C.11 in the WISC–V Administration and Scoring Manual Supplement reports this information by total sample and by ability level. One portion of this table reports the information for children with GAI ≥ 120. The 13 index scores available on the WISC–V can be subdivided into three categories: primary, ancillary, and complementary. The five primary index scores are derived from administration of the 10 primary subtests, supported by factor analysis, and theoretically and clinically driven. For the WISC–V, the colors are yellow, blue, and red; green is not included. This means that for the most common color blindness (green/red, which is 7%-10% of boys), the children will be able to take it without a problem.
