SUBJECT:Times of Student Enrollment for Parking Analysis

Per your request, I have grouped student enrollment by course start times. The sections are grouped into two-hour blocks of time. Students taking at least one course during each time period were counted once during that period. Since TBA classes do not have start times listed, the figures presented below may undercount the total number of students enrolled at any given time by as much as 3%. Sections that meet multiple days or have multiple start times have been counted each time the students are likely to be in class.

Figure 2 includes enrollments in Monday thru Thursday sections for the 2002-03 Fall, Winter, Spring, and Summer quarters. Figure 3 lists the number of sections offered each period, indicating how many faculty members are likely to be on campus during a particular time period. Figure 1 below is a graph of the enrollment during Monday for the fall term. Monday in the fall quarter has the largest course enrollment.

9-11 am is the peak period for all days and quarters, with about 25% of daily enrollments. During this period there are nearly 7,000 students enrolled in class with an additional faculty presence of about 250. Each day approximately 325 classified and administrative staff work on the De Anza College campus.
