Competency tests may be invalid because people have different kinds of problems. In addition, these tests do not measure the competency of people who solve problems in unorthodox ways. (LS)

One major reason for the problems of test validation is an overemphasis on the need for empirical validity data, and a failure to recognize the primary importance of explicit verbal definitions of what the test is intended to measure and rational arguments in support of the means chosen for obtaining the measurement.

In response to Ebel (TM 508 146) Gardner argues that neither intrinsic rational validity associated with ability tests nor a validity coefficient relating a test to performance as the sole information about validity is sufficient. All relevant data about a test and its functioning are essential in describing the validity of the test. (Author/LC)

Construct validity was investigated for three tests of clinical competence in medicine: National Board of Medical Examiners examination (NBME), California Psychological Inventory (CPI), and Resident Evaluation Form (REF). Scores from 166 residents were analyzed. Results suggested low construct validity for CPI and REF scales, and moderate…

This study compared 4 methods (2 case history and 2 performance-based) used to classify the status of adult subjects in familial studies of developmental language disorders, involving 24 parents of children with developmental language disorders and 24 unrelated adult controls. Classification by case history found fewer affected adults than…

It has long been assumed that Part 3 of the National Boards, which stresses patient management and clinical problems, is a valid measure of "clinical competence" for doctors. These authors, challenging this premise, devised a study to analyze which components of medical school achievement are most predictive of Part 3 performance. Their…

Positive approaches to increase student achievement in language classes focus on the potential influence of norm-referenced and criterion-referenced tests. The author cites instances to prove that teacher efficiency increases when teachers are held responsible for student achievement. Discussion of success factors relates testing practices…

Legal issues associated with competency testing of teachers are reviewed, with an emphasis on the problem of bias against minority examinees taking standardized tests. The central legislative foci of legal activity in this area are Titles VI and VII of the Civil Rights Act of 1964. Title VII requires employers to show, with validation studies,…

The Micro-TOWER System of Vocational Evaluation was developed in response to the need for a revision of the TOWER (Testing, Orientation, and Work Evaluation in Rehabilitation) System. The Micro-TOWER system of work sample tests measures the major aptitudes required for most semi-skilled and unskilled occupations. It may be used as a screening…
