Traditional methods of assessing personality traits in medical school selection have been heavily criticised. To address this at the point of selection, "non-cognitive" tests were included in the UK Clinical Aptitude Test, the most widely-used aptitude test in UK medical education (UKCAT: http://www.ukcat.ac.uk/). We examined the…

Medicine is a profession with a long history of research and high standards of methodological rigour and evidence-based decision making. These standards are being transferred into medical education. Universities are starting to collect high-quality data on their admissions systems. This has not been a short-term proposition. Medical courses are…

An investigation was conducted to determine the effects of response-category weighting and item weighting on reliability and predictive validity. Response-category weighting refers to scoring in which, for each category (including omit and "not read"), a weight is assigned that is proportional to the mean criterion score of examinees selecting…

Evidence on how the psychometric properties of verbal and quantitative academic aptitude tests are affected when item options are weighted using rather simple conceptual procedures is presented. This is discussed in connection with the scoring methods used on the Graduate Record Examinations. (DG)

A visual display is introduced that enables one to compare the predictive validities of all possible non-negatively weighted sums of two predictors. This two-predictor validity curve assesses the level of predictability of a criterion from composites of two predictors. Derivations are presented for the general case. For illustrative purposes, the…

COUNSELORS OFTEN ADMINISTER TESTS OF QUESTIONABLE VALIDITY. IN RELIABILITY STUDIES, EVERY PRECAUTION IS TAKEN TO STABILIZE THE STIMULUS SITUATION. IN ASSESSING VALIDITY, CONCERN CENTERS ON BEHAVIOR UNDER DIFFERENT STIMULUS CONDITIONS. CRONBACH'S THEORETICAL LIMIT FOR A VALIDITY COEFFICIENT OF A TEST IS THE SQUARE ROOT OF THE RELIABILITY…

Data from the National Science Foundation Fellowship applicant records and the NRC Office of Scientific Personnel Doctorate Records File were utilized to evaluate the potential of GRE Aptitude and Advanced Tests as predictors of whether or not the candidate attained the doctorate within a period of from seven to ten years. In addition, the study…

The fairness of testing practices for selection or promotion of members of different racial and ethnic groups has been questioned. In this study, a search was made of occupations in the Federal Government to find those in various agencies with sufficient ethnic group representation for acceptable sample size, and for which dependable and objective…

This research report recounts the procedures, results, and recommendations of a research project in which more than 200 tenth-grade students in Florida were tested (1) to determine whether aptitude treatment interaction (ATI) effects on syntactic maturity and on knowledge of structural relationships occur after several months of instruction; (2)…

The primary purpose of the present research was to explore the relationship of ability and intrinsic motivation in the prediction of job performance. Intrinsic motivation was traced to two primary determinants. One, an organizational factor, is the extent to which an employee's job is "enriched," or incorporates challenging elements such as…
