AB - The purpose of this study was to evaluate the validity of Kongju Early Developmental Assessment System-Screening Test (KEDAS-S) as a developmental screening instrument by examining the specificity, sensitivity, and agreement index as well as overrefferral and underreferral rates. This study also investigated the KEDAS-S identification rate of children who need special services among participating children. A total of 92 children ages between 3-5 were sampled for this research. Korean K-ABC and K-DIAL3 were administered to the children after the KEDAS-S test. Sensitivity and specificity results were obtained from the use of cut-off scores.The results indicated that the KEDAS-S correctly identified 50 % of the children who might need special services, demonstrating high rates of sensitivity. The optimal sensitivity achieved with the IQ 70 of K-ABC and all cut offs of K-DIAL 3, demonstrating 97% accuracy of identifying the children. The results also indicated that the KEDAS-S identified correctly more than 94% of the children who may not need special services, regardless of the cut-off scores, demonstrating high rates of specificity. The overall agreement index of the KEDAS-S was .96-.97. It was found that the overreferral rates of KEDAS-S were 5% and underreferral rates were 1%.
