A United States Employment Service (USES) General Aptitude Test Battery (GATB) plan was formulated to evaluate and develop additional job-related assessment methods. Eighteen alternative predictors were reviewed, from which biodata was selected for development. The literature indicates that biodata provides increased validity with little or no adverse impact. The focus will be on writing that will generalize across an occupational cluster and on the identification of relevant constructs. Items will inquire about background information and life experiences and will be screened for bias. Various scoring methods will be reviewed and evaluated as research progresses. The plan includes administration of the experimental biodata instrument along with the GATB. Future results will demonstrate whether biodata, with or without the GATB, improves validity and reduces adverse impact. Five tables summarize testing plans. (Author/SLD)
