An experimental screening device designed to predict future academic failure in kindergarten children was administered to a group of kindergarten children in April. The prediction of success or failure made on the basis of the screening was correlated with the results of standardized reading readiness tests, as well as standardized achievement tests in first and third grades, and with chronological age. The point biserial correlations between predicted success-failure and actual achievement in reading and arithmetic were significant at the .01 level. Correlations between age and achievement were not significant. The efficiency was 100% and the effectiveness was 82%. (Author)
