THIS STUDY ATTEMPTS TO DETERMINE FACTORS WHICH INFLUENCED A SELECTED GROUP OF TWO-YEAR COLLEGES TO EXPAND, TO IDENTIFY THE PROBLEMS ENCOUNTERED IN THIS TRANSITION, AND TO DEVELOP A SET OF GUIDING PRINCIPLES AND PROCEDURES WHICH WOULD PROVIDE DIRECTION AND ASSISTANCE TO COLLEGES CONSIDERING EXPANSION TO FOUR-YEAR CURRICULA. CASE STUDIES OF TEN INSTITUTIONS (REGIONALLY ACCREDITED BOTH AS TWO-YEAR AND AS FOUR-YEAR COLLEGES) ARE INCLUDED. DATA FOR THE STUDY CAME FROM INTERVIEWS WITH ADMINISTRATIVE AND TEACHING PERSONNEL, RECORDS, REPORTS, AND OTHER MATERIALS PROVIDED BY THE COLLEGES, STATE OFFICES OF HIGHER EDUCATION, REGIONAL ACCREDITING AGENCIES, AND LOCAL NEWSPAPERS. FACTORS INFLUENCING EXPANSION TO FOUR-YEAR PROGRAMS FELL INTO TWO CATEGORIES--THOSE INTERNAL TO THE INSTITUTION, AND THOSE EXTERNAL TO THE INSTITUTION. THE PROBLEMS ENCOUNTERED IN THE TRANSITION ARE DISCUSSED UNDER EIGHT CATEGORIES--(1) OPPOSITION TO EXPANSION, (2) FINANCES, (3) PHYSICAL PLANT, (4) ORGANIZATION AND ADMINISTRATION, (5) CURRICULUM, (6) FACULTY, (7) LIBRARY, AND (8) STUDENT SERVICES.
