Abstract. This research determines the effectiveness of the Supreme Elementary Learner Government (SELG) Programs and their influence on the development of elementary learners in Tagudin District, Ilocos Sur. Employing a quantitative-descriptive research design, the study investigates the characteristics of respondents, such as age, gender, educational background, training, and experience as SELG advisers. It also assesses the impact of different SELG initiatives, including involvement in Brigada Eskwela, coordinating Teachers' Day events, and spearheading environmental projects. The study seeks to evaluate student behavioral growth, accountability, and community engagement changes. Data was gathered using a validated questionnaire from 42 teachers and 21 SELG advisers. The results indicate that most respondents have favorable characteristics for successful leadership in the SELG framework. The effectiveness of SELG programs is considered acceptable, showing a beneficial impact on learners' transformation. Notably, specific respondent characteristics considerably impact program effectiveness, underscoring the need for training and seminars to improve leadership abilities. The research finds that SELG programs promote civic engagement and comprehensive development among learners. Enhanced Supreme Elementary Learner Government Development Plan is considered highly valid, indicating its ability to enhance educational practices. Suggestions involve continuous leadership development, personalized mentoring, and frequent assessments to improve the impact of SELG initiatives. This study provides important insights for school leaders, teachers, and upcoming researchers, highlighting the necessity of ongoing enhancement in student government initiatives to develop responsible and active citizens. Overall, the research highlights the vital importance of civic education in developing engaged and informed individuals poised to bring about positive transformations in their communities.
