Background/Context: Confirmatory factor analysis (CFA) model is a commonly adopted framework to estimate and test a measurement model. Once a well-fitting final CFA model is selected, the selected model may be used to test structural relationships of the latent constructs with other variables, to construct a test with desired reliability and…

Student self-assessment is a central component of current conceptions of formative and classroom assessment. The research on self-assessment has focused on its efficacy in promoting both academic achievement and self-regulated learning, with little concern for issues of validity. Because reliability of testing is considered a sine qua non for the…

Results of a reanalysis of previously published data (B. M. Byrne, 1989) support the correlated uniqueness model, diagnostic tests of the validity of confirmatory factor analysis (CFA), multitrait multimethod (MTMM) solutions, inclusion of external validity in MTMM design, and application of factorial invariance to test stability of CFA-MTMM…

Twenty-one studies that reported mean score differences between the Woodcock-Johnson Tests of Cognitive Ability (WJTCA) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) Full Scale are summarized. The differences are found to be minimal and are attributed to data bias and WJTCA's higher correlation with achievement. (EGS)

Using research findings and statistics to support a policy argument often leads to misinterpretations and exaggerations of public school performance. Two experts illustrate this point by discussing examples of distorted high school drop-out rates, student performance on standardized tests, and international comparisons of U.S. and Japanese…

Researchers too frequently consider the reliability of the scores they analyze, and this may lead to incorrect conclusions. Practice in this regard may be negatively influenced by telegraphic habits of speech implying that tests possess reliability and other measurement characteristics. Styles of speaking in journal articles, in textbooks, and in…

Procedures that have been used for assessing a discrepancy between ability and achievement of students suspected to have a learning disability are examined. Methodological deficiencies and/or unavailability of conclusive validity evidence are cited to support the conclusion that all of the procedures are worthless for screening purposes. (SEW)

Kramer's study supporting the construct validity of the Fundamental Interpersonal Relations Orientation-Behavior (Firo-B) scale was replicated in this experiment. The significantly different results reported by Froehle may be due to differences in the populations sampled and in their environment. (GDC)

In September 1991, the National Assessment Governing Board (NAGB) announced standards for basic, proficient, and advanced achievement in mathematics and reported that few American students had reached these standards. Expert reviewers noted technical problems with the NAGB approach and questioned its results. In this report, the NAGB…
