IN CELEBRATION OF THE FIRST FIFTY YEARS OF ITS EXTENSION DIVISION, THE UNIVERSITY OF WISCONSIN PUBLISHED THE STORY OF ITS CORRESPONDENCE STUDY PROGRAM, WHICH OUTLINED FACTORS AFFECTING ITS DEVELOPMENT. A PREDICTED INCREASE OF ENROLLMENT WAS ATTRIBUTED TO SUCH FACTORS AS FEDERAL ASSISTANCE TO SERVICEMEN AND INCREASED ACCEPTANCE OF THE CORRESPONDENCE METHOD. STATISTICS ON STUDENT ACHIEVEMENT SHOWED THAT CORRESPONDENCE STUDY WAS AS EFFECTIVE AS RESIDENT CLASSROOM INSTRUCTION. MILESTONES IN THE HISTORY OF THE DIVISION INCLUDED THE FARMERS' INSTITUTES BEGUN IN 1885, THE ORGANIZATION OF THE EXTENSION DIVISION IN 1906, AND THE CREATION OF A SEPARATE EXTENSION STAFF IN 1908. MEMBERS OF THE STAFF WROTE TEXTBOOKS FOR CORRESPONDENCE STUDY AND TESTED THEM IN CLASS SITUATIONS. THE WIDE PUBLICITY GIVEN THE TEXTS WAS A FACTOR IN THE TREMENDOUS INCREASE IN ENROLLMENT, WITH THE PEAK OF OPERATION IN JULY 1920 WHEN 33,659 PERSONS WERE ENROLLED IN VOCATIONAL COURSES AND 14,989 IN ACADEMIC COURSES. THE CREATION OF CLASS CENTERS THROUGHOUT THE STATE AND COOPERATION IN THE USAFI PROGRAM GREATLY AFFECTED EXTENSION AT WISCONSIN. SINCE 1954 THERE HAVE BEEN STEADY INCREASES IN ENROLLMENT IN CORRESPONDENCE COURSES. (RT)
