In 1981, a national survey entitled Leaders in Transition was conducted to determine biographical and employment information about upper-level administrators at four-year colleges, as well as information about job characteristics and issues facing administrators and their institutions. The sample consisted of approximately 4,000 administrators from a total population of 20,000 administrators in 1,600 institutions. Study findings were used to investigate the question of institutional crossover, i.e., the specific situation in which current four-year college and university administrators were previously employed at a two-year college. Of the 2,896 respondents to the survey, 170 (5.8%) had at one time held at least one position at a two-year institution. Responses from this group indicated: (1) the largest percentage of two-year college crossovers (52.9%) were currently employed in liberal arts colleges, compared to 39.8% of the general sample; (2) barely 10% of the institutional crossovers were employed in doctoral-granting institutions; (3) the administrative positions most frequently held by two-year college personnel were student affairs officer (8.8%), registrar (7%), dean of continuing education (6%), chief academic officer (5%), and head librarian (5%); (4) like the general sample, the crossover group was comprised mostly of males, between 35 and 50 years of age, who held associate or full professor ranks; (5) the crossover group was better educated than their administrative peers; and (6) in comparison to crossover men, crossover women were more likely to hold two--as opposed to three--degrees, were employed in a smaller number of positions, were more likely to have a mentor, and were younger. A literature review on faculty and administrator mobility is included. (EJV)
