We had three research objectives based on teachers’ level of lesson preparation, utilization of teaching-learning time and classroom management strategies as monitoring tools for efficiency in the provision of education. The study employed descriptive survey research design in which questionnaires, classroom observation schedules, observation checklists and document analysis were used as instruments for data collection. The sample size was 283 comprising 3 head-teachers, 30 teachers both of whom were purposively sampled and 234 students who were randomly sampled. 16 classrooms were observed. Data collected were analysed using appropriate descriptive statistical methods The research findings indicate that teachers mostly prepared for lessons but did not utilise teaching-learning time well. The study has also established that classroom management strategies used were inappropriate and recommends for the inclusion of in-service training programmes in educational planning. _________________________________________________________________________ Key Words: Teacher Effectiveness, Teacher Efficiency Teaching and Learning Strategies Quality Education, Public Secondary Schools
