When parents are actively engaged in their children's education—through activities such as attending school meetings, helping with homework, and fostering educational aspirations—it often leads to improved academic achievement. This paper aimed to establish which domain of parental involvement shows significant relationship with students’ academic achievement. Using a standardized adopted questionnaire, the study surveyed 96 parents of college students enrolled in San Agustin Institute of Technology through purposive sampling procedure. The demographic profile revealed that most of the parents were married (83.33%) and high school graduates (43%). Additionally, in terms of family monthly income, most parents earned below P10,000.00 ($171.84), and a majority were farmers (34.46%). Regarding the level of variables, parental involvement was high. In terms of their children's academic achievement, most students earned very good grades in both the 1st and 2nd semesters. When the test of relationship was executed, it was found that parental involvement is significantly associated with academic achievement. This suggests that parents’ involvement and support in their children's academic endeavors are linked to higher academic grades, particularly by enhancing children's learning in the home environment and utilizing community services in school programs. Thus, there is a need to intensify parents’ involvement in their children’s education, even at the college level.
