Findings revealed that there were positive significant relationships between peer pressure and dropout syndrome and home environment and dropout syndrome among adult learners in Agege local government area of Lagos state (r = .983, N = 230, p < .05 and r = -.992, N = 230, p < .05) respectively. Also, there is significant combined contribution of peer pressure, age, gender and home environment to dropout syndrome among adult learners in Agege Local Government Area, Lagos State,(F(4, 225) = 4799.93, p < .05, R² = 0.988).
