Research was conducted to investigate the relationships between the SATs, SAT preparation courses and academic self-efficacy. Previous research indicates a significant link between academic self-efficacy and academic achievement. This study leads to a better understanding of the effects of SATs and SAT preparation courses on academic self-efficacy. A survey assessing academic self-efficacy measured at distinct points in the standardized testing process was distributed to a random sample of Muhlenberg students. Results indicate that SAT preparation courses do increase an individual's academic self-efficacy. The results of this study suggest that access to SAT preparation courses improve one's confidence in academic performance in college, which may in turn affect overall academic achievement.
