Parental involvement refers to parents' participation in their children's educational activities at home and school, such as assisting with homework, attending events, and talking with teachers. At the elementary level, such involvement is critical for improving academic performance, motivation, and general development. The purpose of this study is to evaluate the relationship between parental participation and primary pupils' academic performance. A random sample of 100 students in grades 3-5 and their parents was drawn from a private school. Data were gathered using a parental participation frequency measure and academic grades from school records. The study discovered a strong positive connection (r = 0.61, p < 0.01) between parental participation and academic achievement. Activities such as homework assistance, reading with the child, and regular teacher communication were important contributions. The findings emphasise the importance of effective school-family partnership in increasing student achievement.
