Supplementary data on college student financial aid recipients for academic years 1980-1981 through 1983-1984 are presented for a sample of the Senior Cohort of the High School and Beyond Study (HS&B). By 1984 the HS&B senior cohort had been out of high school for 4 years. Background information on the Center for Education Statistics Longitudinal Studies Program and the HS&B Study is included. This Financial Aid Supplement contains six data files: data on 11,995 students in the HS&B Senior Cohort follow-up sample; data from the students' postsecondary schools; data from the Guaranteed Student Loan (GSL) program records for 1981-1984; data from Pell Grant disbursements files for 1980-1984; GSL guarantee agency disbursement data for 1980-1984; and data from the HS&B Postsecondary Education Events file. Each file is provided in two formats: (1) a raw data file in EBCDIC character form with fixed length records; and (2) a Statistical Analysis System data set, which contains all the data found in the corresponding raw data file. In addition to numerous financial aid variables, the files cover selected student and family characteristics, high school and educational background information, and employment status variables. (SW)
