Student employment while in college during 1980-1984 is presented, based on the High School and Beyond data for 1980 seniors. Who was working, how much was earned, what kind of jobs students held, and how employment was related to college persistence are described. Data are limited to traditional college students during 1980-1984. An introduction looks at: the purpose; high school and beyond data; analysis procedures; and organization of this report. Chapters focus on the following: people working in college; amounts college students earned; the number of different jobs college students had; kinds of jobs college students had; number of hours per week college students worked; hourly earnings; and the relationship of work to persistence in college. Variables of type of institution, academic year, race/ethnicity, family income, and ability level were considered. Among the findings are: a greater concentration of jobs in the service sector among college students than in the total civilian labor force, with 23% of the student jobs were in occupations connected with the service industry; about 1 in 12 students worked more than full time while attending college full-time, but 25% worked less than 20 hours per week during the academic year; and those who worked during the academic year improved their persistence, while those who worked in the summer did not. Three appendices discuss: methodology and technical notes, accuracy of estimates, and confidence levels; supporting tables for figures one through four; and occupational classification. Tables and figures are described. (SM)
