Information on why entering college students leave New Jersey is presented. Attention is also directed to characteristics of high school seniors who choose out-of-state colleges, including their grade point average, rank in class, Scholastic Aptitude Test scores, family income, and parental education. Seniors who could be attracted to New Jersey's colleges and toward whom more active recruitment efforts should be directed are also described. Additionally, implications for systemwide enrollment are considered, along with the academic profile of entering freshmen that would result from larger numbers of prospective out-migrants entering the state's institutions. Major findings, which are based on a 1982 survey of over 5,000 high school seniors, include the following: two-thirds of seniors who planned to attend college and who expressed a preference for an out-of-state institution indicated that the institution's reputation for high academic quality was one of the three reasons for their selection; and 39 percent of seniors cited the availability of a particular educational program at the chosen out-of-state institution as one of the three reasons for their selection. Appendices include the senior questionnaire and information on selected out-of-state institutions chosen by 1982 New Jersey college-bound students. (SW)
