Preschool Denver Developmental Screening Test as a predictor of later school problems.
We compared three preschool tests as predictors of school problems at the end of first grade. A stratified sample of 113 4 1/2- to 5 1/2-year-old children, oversampling those at risk for developmental difficulties, was administered the Denver Developmental Screening Test (DDST), the Stanford-Binet IQ test (SB), and a two-stage shortened form of the DDST in the spring before school entry. Data from achievement tests, special class placement, and grade retention were obtained for 106 of the children at the end of first grade. Eighty-four percent of children with abnormal DDST scores had school difficulties by the end of first grade, compared with 47% of children with scores in the questionable range and only 15% of children in the normal range. Prediction from the SB was not as accurate; 72% of the children who scored less than 68 and 42% of those who scored between 68 and 84 on the preschool SB had school problems. Prediction for those children who had abnormal or questionable scores on the two-stage DDST was as good as prediction from the full DDST. However, far fewer of the total number of school problems were identified by the two-stage DDST. It appears that the DDST can be used on an individual basis for prediction of school problems.
