Abstract: The Treffinger Learning Model (TLM) is a structured approach to fostering creative thinking and problem-solving skills through three phases: basic tools, practice with the process, and working with real problems. It emphasizes student-centered learning, encouraging learners to explore multiple solutions and apply creative strategies in academic and real-life contexts. This study investigated the impact of the TLM on students’ creative thinking skills of Grade 8 students of Banisilan National High School for academic year 2025-2026. The study utilized quasi-experimental research design involving two intact sections: TLM (n=40) and non-TSI (n=35). The data were collected using teacher-made creative-thinking open-ended tests. Although the study revealed that the level of students’ creative thinking skills in their pretest and post-test result both for TLM and non-TLM groups were very low, Quade’s Nonparametric ANCOVA confirmed a significant difference between the two groups. To strengthen students’ creative thinking skills, integrating the Treffinger Learning Model into mathematics instruction is recommended, alongside ongoing teacher training to ensure its sustained impact.
