Co-Curricular Involvement and Academic Performance of Basic Education Learners in a Philippine University

Education plays a vital role in the holistic development of learners. However, learning extends beyond the confines of the classroom and occurs in various contexts and experiences. Grounded on Astin’s Theory of Student Involvement (1984), this study examined how students’ investment of time, energy, and commitment in co-curricular activities influences academic performance. Using a correlational research design, 220 learners were selected through stratified random sampling. A validated questionnaire was used to gather data on co-curricular involvement. General Weighted Average (GWA) was obtained through official academic records. Descriptive statistics, Kruskal–Wallis tests, Spearman’s rank correlation, and Simple Linear Regression were employed in the analysis. Findings showed that Basic Education learners reported very high levels of involvement (median = 4), with the widest variation in Junior High School (SD = 0.641). Academic performance was strong overall, with 85.9% of students earning grades of 85 or higher, and more than half (53.2%) clustered in the 90–94 range. Significant differences in co-curricular participation emerged across departments (χ² = 8.80, p = 0.012) and age groups (χ² = 12.0, p = 0.003). Furthermore, a weak but significant positive correlation was found between co curricular involvement and GWA (r = 0.143, p = 0.034), while regression analysis revealed a moderate positive relationship (r = 0.374), with participation accounting for 14% of the variance in GWA (R² = 0.140). The study concludes that co-curricular involvement supports strong academic performance, though its effects are modest and vary across grade levels. Structured programs at the elementary level foster consistent engagement, while adolescent learners thrive when opportunities balance autonomy and academic integration.
