Class Attendance in College

A meta-analysis of the relationship between class attendance in college and college grades reveals that attendance has strong relationships with both class grades ( k = 69, N = 21,195, ρ = .44) and GPA ( k = 33, N = 9,243, ρ = .41). These relationships make class attendance a better predictor of college grades than any other known predictor of academic performance, including scores on standardized admissions tests such as the SAT, high school GPA, study habits, and study skills. Results also show that class attendance explains large amounts of unique variance in college grades because of its relative independence from SAT scores and high school GPA and weak relationship with student characteristics such as conscientiousness and motivation. Mandatory attendance policies appear to have a small positive impact on average grades ( k = 3, N = 1,421, d = .21). Implications for theoretical frameworks of student academic performance and educational policy are discussed.
