Co-curricular activities provide prospects for better youth development and growth experiences. These activities are particularly good at providing opportunities for students to work in teams, to exercise leadership, and to take the initiative themselves. The active participation of the students is required to reap out maximum benefits out of such activities. The present study utilized data from 1000 higher secondary school students to find out the influence of parental factors in perceiving the psychological values of co-curricular activities and in improving their personality traits. Findings indicated a negative influence of parents; however the psychological values of co-curricular activities exerted significant positive influence on the selected personality traits of higher secondary students. The results point out the need to ensure effective participation of students in co-curricular activities which could boost their personality.
