This paper examines quality assurance mechanisms as correlates of goal achievement of Universal Basic Education (UBE) in public secondary schools of Kwara State, Nigeria. A structured questionnaire was developed and issued to collect information from the study samples. The questionnaire was administered to one thousand, five hundred (1.500) respondents. Data collected were analysed using mean, standard deviation, factor analysis, correlation analysis and regression analysis. The results of the study revealed that instructional supervision, staff development practices, continuous assessment and learning environment had a significant positive relationship with goal achievement in UBE public secondary schools. From the results, it was recommended among others that ministry of education should organise workshops and seminars on quality assurance mechanisms, so that principals and teachers could gain in-depth knowledge and understanding of the identified quality assurance mechanisms.
