The manual was designed to aid members of admissions committees in the use of the new Medical College Admission Test (MCAT) for the selection of applicants, and to familiarize health professions advisors and other groups of the basic characteristics of the test and its selection and counseling functions. The first chapter includes a rationale for the development of the new test and test specifications and development information. Characteristics of the subtests and a comparison of the new and old test are also provided. Chapter 2 discusses the scoring procedures for the new test including methods of calculation, score reporting formats, and equivalence scales. In chapter 3 the technical considerations of the interpretation of the new test are assessed in areas such as reliability and independence of measured abilities. The fourth chapter surveys the normative considerations of interpretation including the use of the test by the undergraduate major, by racial and ethnic background, and by sex. Chapter 5 details the use of the new MCAT in admissions decisions. The final chapter presents preliminary research and implications on the test. Technical supplements provide facts on the speededness of the test, and methods for converting raw scores and equating successive forms of the test. Guidelines for calculating local norms are appended. (PHR)
