This study investigated the roles of parents and teachers in the effective implementation of the Universal Basic Education (UBE) program in secondary schools within Kwara Central, Nigeria. Utilizing a descriptive research design, the study examined the level of involvement parents and teacher involvement in the UBE program in Kwara Central Senatorial District. The population comprised all parents and teachers of JSS 1 and JSS 2 students in public secondary schools across the four local government areas of Kwara Central: Ilorin West, Ilorin East, Asa, and Ilorin South. Simple random sampling technique was employed to select five schools from each of the local government areas, totaling twenty schools. Purposive sampling technique was used to select ten parents and ten teachers from each school, resulting in a total of 400 respondents. Data were collected using a selfdesigned questionnaire titled 'Parents Teachers Involvement on Modalities for the Implementation of UBE Questionnaire' (PTIMIUBEQ). The findings underscored the critical role of teachers, whose high level of involvement significantly enhances the program's implementation, contrasted with the average involvement of parents, which suggests areas for potential improvement in parental engagement. The study recommended regular organization of workshops and community meetings to raise awareness among parents about the importance of their active involvement in the UBE program, creation of formal structures like Parent Teacher Associations (PTAs) where parents and teachers can meet regularly as well as the introduction incentive programs such as recognition awards, certificates, reduced school fees or subsidized school materials for parents who actively participate in their children's education.
