Associate degrees are commonly conferred by community colleges. This degree is awarded upon a student’s satisfactory completion of a program of study. Students who have maintained continuous enrollment have the option of completing the Associate Degree requirement in effect at the time they initially enrolled or any subsequent catalog up to and including the last semester of attendance. The Associate Degree is one of two types, the Associate in Arts or Associate in Science. The distinction between the degrees lies in the majors. An Associate in Arts Degree includes at least eighteen units in Social Science, Humanities and Arts courses. An Associate in Science degree includes at least eighteen units in Science, Math and Technical courses.
