The four-year program is designed for students for whom attendance on a full-time basis would be difficult for economic reasons or because of job, family, or other responsibilities.
The program requires attendance an average of 10 hours a week, evenings, over four academic years, plus enrollment in at least one summer session (where classes are offered in the evening). Although most students in the four-year program enroll in evening classes, the school also welcomes part-time day students.
