Understanding personal factors that contribute to university student satisfaction with life is important in order to determine how we can better prepare students for the transition to post-secondary education and support them during this transition. This study examined predictors of university student satisfaction with life, academic self-efficacy, and self-reported academic achievement in their first year of university. First-year students (n = 66) completed selfreport measures of academic achievement, university well-being, satisfaction with life, personality, and mental health. A linear regression analysis approach was applied to the data. Results indicated that academic satisfaction and school connectedness predicted satisfaction with life but that academic self-efficacy and college gratitude did not, conscientiousness predicted academic self-efficacy, college well-being predicted self-reported achievement, and anxiety predicted achievement but depression did not. This study highlights the importance of understanding the personal factors that influence well-being and achievement during the transition to university.
