Abstract

The predictive validity of the Gesell School Readiness Tests (GSRT) is examined by correlating measured developmental age and performance in first grade. A sample of 45 students referred by their teachers for developmental testing and a random sample of 106 students chosen expressly for this study were tested with the GSRT. A small positive relationship was found between Gesell developmental age and first-grade report card grades ( r = .23). Additional outcome measures were available for a subgroup of the total sample and indicated that the GSRT has modest predictive validity for standardized tests and low validity for teacher judgment of performance in first grade. Issues concerning misidentification of ready children and treatment efficacy are also discussed. The low predictive validity of the GSRT does not support its use for school readiness assessments leading to placement decisions.
