The Predictive Relationship of ITBS and ITED to Measures of Academic Success

Abstract

This study investigated the relationship between achievement test scores on the Iowa Tests of Basic Skills, the Iowa Tests of Educational Development, and academic success, as measured by high school and first-year college grade point averages (GPA). The population consisted of 1,147 students who entered the University of Iowa as freshmen in 1991. Achievement test scores obtained in Grades 3 through 12 were available for a substantial portion of the population, along with high school and college GPAs. The correlational analyses indicated that there were significant relationships between 3rd- through 12th-grade achievement test measures and GPA. However, the magnitudes of these relationships, contrary to previous findings, were surprisingly low.
