THIS SERIES OF FOUR SURVEYS DESCRIBES SUBSEQUENT ATTENDANCE PATTERNS OF FRESHMEN WHO ENROLLED IN THE FALL 1958 AND 1962 CLASSES AT THE EIGHT 2-YEAR CENTERS OF WISCONSIN UNIVERSITY. THESE CENTERS ARE A SEPARATE UNIT OF THE UNIVERSITY, RESPONSIBLE TO THE CHANCELLOR OF THE CENTER SYSTEM, WHO IN TURN REPORTS TO THE UNIVERSITY PRESIDENT. THE MAY 1966 PAPER REPORTS THE PROGRESS OF THE FALL 1958 FRESHMEN AFTER TRANSFER TO THE MADISON CAMPUS. IT COMPARES THEM WITH THOSE WHO ENTERED MADISON AS FRESHMEN, THEIR GPA'S AT MADISON AND AT THE CENTERS, AND THEIR GRADUATION RATE WITH THAT OF THE MADISON FRESHMEN. THE OCTOBER 1966 STUDY FOLLOWS THE 729 OF THESE STUDENTS WHO HAD NOT RECEIVED A DEGREE BY JUNE 1964 TO DETERMINE THE REASONS OF THOSE WHO HAD NOT TRANSFERRED, HAD DROPPED OUT, OR HAD CONTINUED STUDIES ELSEWHERE. THE JULY 1966 STUDY INVESTIGATES THE CHARACTERISTICS OF THE NEW FRESHMAN CLASS OF FALL 1962 AND FOLLOWS THEIR PROGRESS FOR SIX SEMESTERS, WHETHER THEY REMAINED AT THE CENTER OR TRANSFERRED TO MADISON DURING THIS TIME. THE NOVEMBER 1966 REPORT (A SUPPLEMENT TO THE JULY 1966 STUDY ABOVE), FOLLOWS THE FALL 1962 ENROLLEES WHO LEFT A CENTER, DID NOT TRANSFER TO THE MADISON CAMPUS, OR DID TRANSFER BUT STAYED LESS THAN SIX CONTINUOUS SEMESTERS. IT EXHIBITS MORE RECENT TRENDS IN STUDENT RETENTION, TRANSFER, OR DROPOUT. (HH)
