Validity and reliability are a major focus in teacher education accreditation by the Council for Accreditation of Educator Preparation (CAEP). CAEP requires the use of "accepted research standards," but many faculty and administrators are unsure how to meet this requirement. The Standards of Educational and Psychological Testing…

Studies investigating invariance have often been limited to measurement or prediction invariance. Selection invariance, wherein the use of test scores for classification results in equivalent classification accuracy between groups, has received comparatively little attention in the psychometric literature. Previous research suggests that some form…

Rater training is an important part of developing and conducting large-scale constructed-response assessments. As part of this process, candidate raters have to pass a certification test to confirm that they are able to score consistently and accurately before they begin scoring operationally. Moreover, many assessment programs require raters to…

In this digital ITEMS module, Dr. Robert [Bob] Mislevy and Dr. Maria Elena Oliveri introduce and illustrate a sociocognitive perspective on educational measurement, which focuses on a variety of design and implementation considerations for creating fair and valid assessments for learners from diverse populations with diverse sociocultural…

The evidence-centered design framework was used to create a special education teacher observation system, Recognizing Effective Special Education Teachers. Extensive reviews of research informed the domain analysis and modeling stages, and led to the conceptual framework in which effective special education teaching is operationalized as the…

Neil Dorans has made a career of advocating for the examinee. He continues to do so in his NCME career award address, providing a thought-provoking commentary on some current trends in educational measurement that could potentially affect the integrity of test scores. Concerns expressed in the address call attention to a conundrum that faces…

"Scaling" is the process of constructing a score scale that associates numbers or other ordered indicators with the performance of examinees. Scaling typically is conducted to aid users in interpreting test results. This module describes different types of raw scores and scale scores, illustrates how to incorporate various sources of…

The application of generalizability theory to the reliability and error variance estimation for performance assessment scores is discussed. Decision makers concerned with performance assessment need to realize the restrictions that limit generalizability such as limitations that lead to reductions in the number of tasks possible, rater quality,…

Literature related to the multiple true-false (MTF) item format is reviewed. Each answer cluster of a MTF item may have several true items and the correctness of each is judged independently. MTF tests appear efficient and reliable, although they are a bit harder than multiple choice items for examinees. (SLD)

A broad description is given of admissions procedures to Israeli universities. In Israel, a single unified test, the Psychometric Entrance Test, is used for admission to the various universities. Issues of validity and reliability and problems of ensuring fairness for non-Hebrew speakers are considered. (SLD)
