The main purpose of the study was to determine the relationship between the supreme secondary learner government and the center of learning culture. The following objectives were sought: (1) to determine the level of supreme secondary learner government characteristics (2) to measure the level of supreme secondary learner government advocacy (3) to determine the level of the center of learning cultures such as student engagement, diversity, equity, and inclusivity (4) to test whether the level of supreme secondary learner government characteristics has a significant relationship to the center of a learning culture (5) to test whether the level of supreme secondary learner government advocacy has a significant relationship to the center of learning culture (6) to test whether the quality of life experienced by learners within the institution significantly moderate the relationship between the supreme secondary learner government characteristics and advocacy and to the center of learning culture.  The researcher utilized a descriptive design and random sampling to study junior high school students in Unit II, Laguna. Data was collected through a self-made questionnaire and statistically analyzed using mean, standard deviation, and Pearson product correlation. The study found that supreme secondary learner government advocacy and characteristics are significantly correlated with the center of learning culture. The supreme secondary learner government characteristics, advocacy, and the center of learning culture are significantly and positively correlated with the quality of life experienced by the learners. It is therefore recommended that the supreme secondary learner government promote diversity and inclusivity in education through mentorship programs, cultural competency workshops, and mental health awareness. It can also implement anti-bullying policies and counseling services to enhance learner satisfaction and safety. Future researchers may consider the effect of the supreme secondary learner government in shaping the center of learning culture.
