The purpose of this study was to operationalise a model of time orientation and investigate the variability of its factors based on preparation for assessment and perceived academic performance. Responses from 113 male adolescents (mean age = 16.46 years) and 115 female adolescents (mean age = 16.42 years) to items operationalising an expanded model of the contextual approach to adolescent orientation to the future were analysed using principal component analysis. The results rendered five factors including a past orientation, three present orientation factors (task focus, positive social support, and negative social support), and a future orientation. A series of two-way ANOVAs showed an association of present and future time orientation with academic achievement. Results also showed that students' approaches to learning varied mainly as a function of present positive social support and task focus. Students who prepared well for assessment had the highest future time orientation. This research highlights the importance of an elevated present and future time orientation to academic achievement and appropriate preparation for assessment tasks. (Contains 1 figure and 6 tables.)
