Higher academic self-concept (ASC) has been shown to predict future performance and achievement. Marsh and O'Mara (2008) demonstrated that academic self-concept among 10th graders was a better predictor of their educational attainments five years after high school graduation than their school grades, standardized test scores, intelligence, and socioeconomic status. Liem, Marsh, Martin, McInerney, and Yeung (2004) showed that positive academic self concepts were associated with better educational outcomes 10 years later—evidence that ASC can have long lasting effects. ASC has also been tied to decision-making in educational settings. It is a predictor of course choice in high schools, major choice in college, and career path after school. In other words, ASC plays a crucial role in both educational outcomes and career aspirations. As such, the question of how self-perceptions develop and change is a genuinely important research question that has serious implications for education systems.
