Predictive Validity of a Preschool Neurodevelopmental Instrument

The Pediatric Examination of Educational Readiness (PEER) is a combined neurodevelopmental, behavioral, and health assessment for children ages 4 to 6 years old. The purpose of this study was to examine its predictive validity. One hundred seven five-year-olds received the PEER at age five. At age eight, all took the Iowa Tests of Basic Skills (ITBS), a nationally normed achievement battery. Mean ITBS scores were significantly different between those passing and failing the PEER Developmental Attainment section (t = 4.5, df = 105, p less than .001). Of six developmental areas sampled, preacademic skills emerged as the most potent predictor of achievement (R = .43, Re = .18, p less than .001). Neuromaturation scores did not correlate with ITBS results. Sensitivity of the PEER was 45%, specificity was 87% and test accuracy was 79%. We conclude that the PEER is useful in describing current developmental strengths and weaknesses but has limited ability in predicting future learning problems for individual children.
