Malibiran Zussette Candelario-Aplaon Myla V. Izon Abstract. The twin goal of mathematics education is the development of critical thinking and problem-solving. Despite many strategies conducted by the teachers, many students are experiencing problems in understanding and applying mathematics concepts in real-life problems. This study aimed to determine the different factors that influenced the problem-solving performance of the students with the end view of formulating plans and intervention program. Descriptive- correlational design with regression modeling was employed to investigate which among the presented variables determine the problem-solving performance of the respondents. The respondents of the study were the 100 randomly selected Grade 7 students from public secondary schools in MIMAROPA region. The results showed that grades in Mathematics and English, attitude towards mathematics, and comprehension skills of the students as well as gender and teaching loads of the teachers affect students’ problem- solving performance. However, only students’ grade in English and comprehension skills were known determinants of problem-solving performance.
