In Texas, placement of educable mentally retarded (EMR) students has required three factors-- intellectual assessment, educational appraisal, and adaptive behavior. This study examined 28 reclassified EMR students to determine which assessment factor is least stable in defining EMR and to determine significance of change in assessment scores. Data were secured from school records. Type of intellectual assessment test used varied greatly and was found to be the most inconsistent placement factor. However, educational appraisal scores contributed to over half the reclassifications. Adaptive behavior did not contribute to any reclassification. Due to limited sampling and variety of assessment tests, significance of change in scores was not determined. Generally, on retest,performance IQ scores were elevated while verbal IQ scores remained the same.

The problem under investigation was the predictive value of a preschool screen. The subjects were 111 kindergartners. First, the need for a preschool screen was established. Second, the literature concerning other preschool devices was reviewed. Third, a specific screen was assessed in terms of validity. Fourth, a consideration of the predictive value of this screen in relation to scholastic achievement as indicated by the Metropolitan Readiness Test was made. A multiple regression analysis was performed, and the cross-validation of a number of prediction equations and cutoff scores was significant. Although statistical significance was achieved, high-risk youngsters could not be accurately identified. This research indicated that the instrument evaluated shows promise if refined by additional research.
