The performance of the learners in Mathematics is a perennial problem in the academe would it be basic or higher education. The Department of Education is continuously investing and provides training to teachers for the improvement of the achievement level of the students. In particular, 5E Model focused on Inquiry-based Learning was introduced through Learning Action Cell (LAC) sessions to the teachers from Grade 1 to 12. The characteristics of the teachers in lesson planning and delivery of lesson was also measured. The grades of the students in second grading was used as baseline of the intervention. The LAC sessions were conducted within ten Fridays. The educational background of the teachers was also determined and the effectiveness of the LAC session to the performance of the teacher. The findings revealed that teachers have outstanding performance in lesson planning and delivery of lessons. The majority of the teachers are Baccalaureate degree graduates. The results also showed that teachers strongly agree that LAC sessions help improve their teaching performance. Furthermore, it findings showed that there was a significant increase of grades of the students in the third grading. It also showed that educational background and the conduct of LAC session have of no significant relation to students’ achievement, while teachers’ performance has significant relation. It is concluded that teachers’ performance has significant relation to students’ achievement. It is recommended to encourage teachers to pursue post graduate studies, continue the application of 5E model in teaching and the conduct of the LAC session should be done regularly for the entire school year with well-organized LAC session plan.
