This study examines whether congruence between classroom environment and student personality is associated
with increases in student satisfaction and performance. Data were collected from students (n= 1763) at a comprehensive
state university and analyzed usingmixed-level maximumlikelihood polynomial regression analysis
and surface response methodology. Results indicate that student personality is a consistent predictor of student
satisfaction, classroomenvironment is a consistent predictor of performance, and the interplay between the two
is important in predicting satisfaction and performance. The personality characteristics of agreeableness and conscientiousness
and the classroomenvironment dimension of structurewere all positively related to both satisfaction
and performance. Congruence between several personality traits and classroomenvironment elements was
found to increase satisfaction, performance, or both. The implications of these results for instruction and research
on person–environment fit in higher education are discussed
