Medical College Admission Test (MCAT) score differences were examined for Black and White examinees who entered American medical schools in 1978 and 1979. The incidence of academic difficulty resulting in delayed graduation, withdrawal, or dismissal was also examined. The MCAT provides six scores: biology, chemistry, physics, science problems,…

The predictive and incremental validity of both the Old and New Medical College Admission Test (MCAT) was examined and compared with a sample of over 300 medical students. Results of zero order and incremental validity coefficients, as well as prediction models resulting from all possible subsets regression analyses using Mallow's Cp criterion,…

The purpose of this study was to investigate the viability of the property of parameter invariance for the one-parameter (1P), two-parameter (2P), and three-parameter (3P) item response theory (IRT) models for the Medical College Admissions Tests (MCAT). Invariance of item parameters across different gender, ethnic, and language groups and the…

Acceptable performance on the Medical College Admissions Test (MCAT) is necessary for acceptance into medical school; therefore, students planning a career in medicine and their advisors would benefit by having information useful in predicting performance on this examination. The present study examined the validity of the ACT Assessment as such a…

The effectiveness of Medical College Admission Test (MCAT) scores in predicting success during the first phase of medical education is investigated. The process by which medical students are educated and evaluated, the nature and purpose of the MCAT, and the MCAT Interpretive Studies Program developed by the Association of American Medical…

The predictive validity of the new Medical College Admission Test (MCAT) was examined; the validity coefficients were compared to those obtained from previous versions of the MCAT and from performance data gathered early in a first-year basic science program. Data were collected from about 400 medical students, including: (1) MCAT…

The predictive and incremental validity of the New Medical College Admission Test (New MCAT) Science Problems Subtest was examined with a sample of over 165 medical students. Criterion measures were National Board of Medical Examiners (NBME) Part I (basic science) and Part II (clinical science) performance. The Science Problems subscore is derived…

A study followed 66 medical students from matriculation through clerkship to determine the use of an anxiety measure, undergraduate grades, and Medical College Admission Test scores in predicting clerkship performance. Results showed disparities in prediction but suggest that the way students are evaluated in clerkships determined which factors…

The Medical College Admission Test (MCAT) was examined for sex bias. Data for student samples from two midwestern state-supported medical schools were analyzed. The criteria included average course grades in each of the first two years of medical school. Tests comparing various regression models based on male and female subgroups generally failed…

A substantially revised Medical College Admission Test (MCAT) was introduced in spring 1991. The new examination is designed to assess critical thinking skills, basic concepts and problem solving facility in science, and writing skills. This paper reports preliminary findings on the factor structure of the revised MCAT, which consists of four…
