The purpose of the study was to investigate the relative predictive validity of UTME, PUTME, interest scores for achievement in Nigerian Universities. The study examined the relationship among UTME, PUTME, interest and achievement (CGPA in year 2) on the one hand and the prediction of CGPA from the predictors on the other. The data for the study was collected from two sample groups obtained through two stages of sampling in two public universities on Edo State. Data on UTME, PUTME and achievement, were obtained from the schools. Bakare’s Vocational Interest Inventory (VII) was used to collect interest scores at the beginning of 100 level. The primary findings were that: (a) generally low relationships exist among the predictors and the criterion, with the relationship between PUTME and CGPA highest; (b) a low prediction exist between the combination of the predictors and the criterion with less than twenty percent of the variance in achievement explainable by the predictors. These findings led to the conclusion that PUTME should be retained and that the non-intellective domain should be explored for admission into Nigerian universities.
