To assess the convergent validity of the Wide Range Intelligence Test (WRIT) and the Wechsler Abbreviated Scale of Intelligence (WASI), two new brief IQ measures, 66 participants from five rural Illinois public schools were administered both measures in counterbalanced order. All correlations between the WRIT and the WASI were significant. Correlations between the WRIT and the WASI were moderate to high, ranging from .50 (r2 = .25) to .85 (r2 = .72). The WRIT and the WASI appear to be measuring very similar constructs, indicating strong evidence of convergent validity.
