This study determined the level of parents’ awareness and extent of involvement in school activities in relation to learners’ academic performance. Respondents were grouped according to age, family size, highest educational attainment, average family monthly income, and grade level. Parental awareness was assessed in terms of curricular and non-curricular activities, while parental involvement was examined across parenting, communicating, volunteering, learning at home, decision-making, and collaborating with the community. The study also assessed learners’ academic performance during the first and second quarters and examined significant differences and relationships among the variables. The respondents were parents of Grade 6 and Grade 10 learners at St. Sebastian International School-Neg. Occ., Inc., Bacolod City, and data were gathered using a modified parental involvement questionnaire by Alderete. Findings revealed that parental involvement in communicating significantly differed by age, while volunteering showed no significant differences across all demographic variables. In learning at home, a significant difference was found only by grade level. Decision-making significantly differed by age, while collaborating with the community significantly differed by age and educational attainment. No significant relationship was found between parents’ awareness and learners’ academic performance. However, parental involvement was found to have a significant relationship with learners’ academic performance, indicating that greater parental involvement in school-related activities is associated with improved academic outcomes.
