Because of the very early closure of certain courses, a questionnaire was developed and administered to all evening college students registering during a pre-determined period in order to identify enrollment patterns. Another questionnaire was administered following the first census week to students in a 10 percent randomly selected sample of classes that closed late in the registration period and those that did not close, in order to compare the goals of the students, and the completion rate of the students in these classes. All evening college offerings were studied in relation to time of offering and function--meets degree or graduation requirements, or is offered for general personal development--either transfer or non-transfer. The bulk of the courses which closed early were in occupational areas, while the general education courses remained open until the final registration period. The time of the offering did not seem to have as much influence on closure as the day of the offering. The sooner a student enrolled, the more likely he was to complete the class satisfactorily. Day students registered in the evening in order to resolve work or class schedule conflicts, or because a required class was not offered in the day. (Recommendations are made to resolve course offering imbalances, and 16 tables are appended.) (NHM)
