Table 28 (formerly 35) provides summaries by campus of the variations in attendance of students within the college year. Students may attend for as few as one or as many as four terms depending upon the individual campus. Patterns of enrollment are expressed in terms of unduplicated headcount (any student is counted only once). The total college year unduplicated headcount for each campus is derived from the enrollments by term combination.

Rows 1 through 4 of the table (labeled "One Term") present the number of students enrolling for only one term of the 2007-08 academic calendar for any given campus. Rows 5 through 10 present the number of students enrolling for two terms. Since a campus may have as few as two and as many as four terms in its calendar, students counted in these categories may be attending for all or only a portion of a campus academic year depending on the campus. Rows 11 through 14 indicate the number of students enrolled for three terms and row 15 presents the number of students enrolled for all four terms on a year round operation (YRO) campus.

Enrollments in Rows 1 through 15 are "unduplicated"; that is, no student is counted more than once in these rows. For example, none of the enrollment counted in Row 2 (Fall Only) is counted in Rows 5, 8, 9, 11, 12, 14, or 15.

Rows 16 through 19 summarize the by-term enrollment on each campus. As such, they can be calculated by adding together appropriate information from Rows 1 through 15. For example, Row 17 (Total Fall Enrollment) can be found by adding together Rows 2 (Fall Only), 5 (Summer and Fall), 8 (Fall and Winter), 9 (Fall and Spring), 11 (Summer, Winter and Fall), 12 (Summer, Fall and Spring), 14 (Fall, Winter, and Spring) and 15 (All Terms).

Row 20 represents the total number of individuals enrolled at any time during the college year. Again, this figure represents only unduplicated enrollment; students are counted only once regardless of the number of terms for which they were enrolled. For any campus, the Net Individuals shown in the table can be calculated by adding together all of the enrollments shown in Rows 1 through 15.

For the CSU as a whole, a total of 497,932 individuals enrolled at some time during the 2007-08 college year. Of these, about 359,381 or 72 percent were enrolled for a full academic year on a CSU campus. For purposes of comparison, a student attended for a "full academic year" at a YRO campus if they were in attendance for three of the four quarters in the campus calendar. At Stanislaus, "attendance rate" cannot be calculated directly from aggregate data for the CSU; each campus calendar must be taken into account in order to determine the number of students enrolled for the entire year on a given campus.
