This study investigated predictors of seminarians' academic performance. The study employed a correlational research design. Two hundred and thirty two seminarians constituted the sample for the study. Bakare's modified version of student problem inventory was used to collect the data of the study. The findings indicated that time management and lack of concentration significantly predicted the academic performance of seminarians. Based on the findings, the study recommended intervention programmes, such as workshop on techniques of managing external distractions and unresolved personal crises that interfere with the seminarians' concentration level and workshop on time management skills; and that counselling units should be established in the Catholic Major Seminaries in the South-West Region of Nigeria since there is none at the moment.
