title: Assessing the validity of the updated Medical College Admission Test.
abstract: This report represents early information about the validity of the updated Medical College Admission Test (MCAT) battery introduced in 1991. Data are given on both the use of the new examination in the selection of medical students and its estimated predictive value for freshman students' performance. Admission officials from 114 institutions responded to a survey on medical school admission practices and on the use of MCAT data; also elicited were assessments of the examination in relation to its design and implementation objectives. Regression-based evaluations of the predictive validity of the MCAT, undergraduate grades, and of undergraduate selectivity data for first-year grades at 12 institutions are described. Survey responses suggest that MCAT data are viewed in relation to the varied information needs of admission decision making and are supplemented by other academic and nonacademic information in selection. The new battery generally is judged favorably by admission officials. Predictive validity results reflect the usefulness of MCAT scores, undergraduate grades, and selectivity data for identifying individuals apt to succeed in medical school. The authors conclude that preliminary information about the results of the new examination is encouraging. The members of the MCAT Validity Studies Advisory Group, who assisted the authors in framing and conducting the research presented in this report, continue their research and deliberations about the use, utility, and impact of the updated MCAT.
