This document reports on the first segment of a project that estimates the determinants of individual enlistment decisions using the 1992 second followup of the National Educational Longitudinal Study (NELS). The NELS sample contains youths who were high school seniors in 1992. The project's first segment estimates scores on the Armed Forces Qualification Test (AFQT) for NELS respondents, and it uses the results of this estimation to draw some implications for recruiting policy. The second project report will replicate the studies of J. Hosek and C. Peterson (1985, 1990) and estimate additional models of enlistment decisions. The NELS does not contain AFQT scores, but it does contain extensive demographic information on its sample, including scores on mathematics, science, and reading tests. The basic assumption is that a person who scored at some percentile on a NELS test would score at a similar percentile were the same population given a component of the National Assessment of Educational Progress (NAEP) of the AFQT with comparable content. Analyses suggest that in 1992 a higher fraction of youths scored in the ranges that qualified them for military enlistment than was true in 1980. This finding implies that when the AFQT is renormed as planned using a random sample of the youth population collected in 1997, fewer individuals will qualify for enlistment than is currently true using the old AFQT norms. The methodology also suggests a way that AFQT scores renorming could be approximated on a regular basis between National Longitudinal Survey of Youth norming studies. Appendixes contain standard and percentile test score tables and relate test score estimates to recruiting outcomes. (Contains 11 figures, 13 tables, and 36 references.) (SLD)
