In an attempt to reveal the various types of learning environments present in 30 mathematics classrooms in five Catholic high schools, this replication study examined student (N = 602) perceptions of their classrooms using the Classroom Environment Scale. Student attitudes toward mathematics were assessed by the Estes Attitude Scale. Extending previous research conducted in public high schools, this study delineated two basic types of learning environments (teacher-centered and student-centered) in Catholic high schools. In contrast with students in public schools, students in these parochial schools reported positive attitudes toward mathematics regardless of the type of learning environment. Discussion of the findings and implications for practice, including the utility of the CES, are summarized.
