This analysis involves enrollment data from Fall 1966 through Spring 1968. It compares two colleges and all California junior colleges in terms of age (defined as adults, minors, and baccalaureate degree holders or higher) and hours of attendance (12 or more hours as full-time, less than 12 hours as part-time) of students. Tables provide data as follows: (1) annual increase or decrease in graded classes by full-time or part-time students. The part-time category is analyzed as adults (age 21 and over, enrolled for fewer than ten class hours) and other (students with an Associate of Arts degree or higher); (2) same data as above but for ungraded classes (those for adults); (3) Spring 1968 enrollment of freshmen, sophomores, and all others (students with an Associate of Arts degree or higher) in graded classes analyzed by full- and part-time status as described in (1) above; (4) Spring 1968 enrollment of minors, defined adults, and other adults in ungraded classes (classes for adults) analyzed by full- or part-time status.
