It has been alleged that 2-year colleges often seek transformation to a 4-year status. This survey reports on an analysis of institutional changes that have occurred in 72 junior colleges from 1958-59 through 1967-68. Institutional information is profiled on the basis of the following factors: (1) year of academic extension and location by state; (2) institutional control; (3) type of student body; (4) enrollment size; (5) academic calendar system; (6) presence or absence of regional accreditation; (7) year when the regionally accredited institutions first offered junior college work; (8) type of curricula represented on the 2-year campuses prior to academic extension; and (9) type of curricular adaptations accompanying changes to 4-year institutional status. A detailed discussion of these factors as related to the overall spectrum is presented as well as the actual statistical data. (Author/HS)
