A new group of Grade 12 students graduates from high school each year. This is an important time for young adults because they must make decisions for what life after high school will look like. The purpose of this study was twofold: (a) to investigate what decisions students in Alberta are making for after high school, and (b) to examine how such decisions are linked to students' motivation in the form of underlying causality orientations as articulated by self-determination theory (SDT). A total of 237 Grade 12 students responded to a survey with closed and open-ended questions about their plans for after high school. The results showed that all participants had some type of plan for after high school, with 79% planning to pursue post-secondary education. Their reasons could be categorized by causality orientation theory (COT) and revealed differences in reasons between students bound for postsecondary and those not. The paper concludes with suggestions for future research and avenues to aid students in their decision-making process during high school.
