This study evaluated the effectiveness of Project SAYON (Student Aid for Yielding Outstanding Numeracy) as an intervention to enhance mathematical proficiency among Grade 10 students at Luna National High School. Using a pre-experimental design, the study compared pre-test and post-test results to assess the impact of the project. The pre-test indicated a moderate level of proficiency, with a mean score of 10.09. After implementing Project SAYON, the post-test results revealed a significant improvement, with a mean score of 13.52. The hypothesis was tested at a 0.05 level of significance, showing a meaningful difference between the pre-test and post-test scores. This demonstrates that Project SAYON effectively improved students’ mathematical skills by offering targeted tutoring and resources. The study highlights the importance of structured, innovative interventions in enhancing academic performance, particularly in mathematics.
