Research interest in achievement motivation and its correlates has grown in recent years. Though there are thousands of studies on goal orientation, the number of instruments to identify goal orientation based on four-fold model viz., performance approach goal orientation (PAP), performance avoidance goal orientation (PAV), mastery approach goal orientation (MAP) and mastery avoidance goal orientation (MAV) are rare, especially in the non-western education contexts. This paper describes the development of academic goal orientation inventory for adolescent students. Data from 832 higher secondary school students of Kerala chosen through stratified random sampling were factor analyzed to confirm that the responses on the new inventory follows the 2x2 achievement goal-orientation framework proposed by Pintrich (2000) and Elliot and McGregor (2001). This 15 item inventory reliably and validly identifies four goal orientations.
