Abstract
The HS&B study is a national large scale longitudinal survey of a representative sample of approximately 58,000 high school students. The base year survey was conducted in the Spring of 1980 with subsequent follow-up studies in 1982, 1984, and 1986. Information was collected on over 1500 variables including achievement in six different areas measured by a 126-item cognitive test. Previous analyses of the psychometric properties of the cog9itive test indicated minimal evidence of validity and acceptable internal consistency reliability. The purpose of this study was to collect additional evidence for the validity of the cognitive test. Criterionrelated validity evidence was investigated by correlating sophomore and senior year cognitive test results with senior year self-reported grades, class standing, and ACT/SAT standardized test scores. With the exception of the civics subtest, sophomore and senior year subtest scores correlated highly (.64-.83) with senior year ACT/SAT standardized test scores and moderately well (.35-.53) with senior year self-reported grades and class standing.
