While we acknowledge and lay emphasis on the importance of passing examinations, our aim is to develop the total personality of students. It has been found that activities that promote and reward individual talent is best identified when participating, in non-academic pursuits. Therefore we at Alethea give equal prominence to extra curricular activities.

Our students proved that they could balance an excellent academic record along side an award winning co curricular schedule reinforcing our belief that one compliments the other. For those who found that their strengths were in sports or co curricular activities they excelled in their respective fields went on to
lucrative employment in the private sector. To that end, we make it compulsory, for students to take an active role in sports, and other team and leadership building activities. Prospective employers and universities too, look for students, who have participated in sports and co curricular activities, as these make the transition from school to work place smoother.
