Validity is a fundamental consideration of test development and test evaluation. The purpose of this study is to define and reify three key aspects of validity and validation, namely test-score interpretation, test-score use, and the claims supporting interpretation and use. This study employed a Delphi methodology to explore how experts in…

Despite the ease of accessing a wide range of measures, little attention is given to validity arguments when considering whether to use the measure for a new purpose or in a different context. Making a validity argument has historically focused on the intended interpretation and use. There has been a press to consider both the intended and actual…

Researchers have documented the impact of rater effects, or raters' tendencies to give different ratings than would be expected given examinee achievement levels, in performance assessments. However, the degree to which rater effects influence person fit, or the reasonableness of test-takers' achievement estimates given their response patterns,…

This paper illustrates that the psychometric properties of scores and scales that are used with mixed-format educational tests can impact the use and interpretation of the scores that are reported to examinees. Psychometric properties that include reliability and conditional standard errors of measurement are considered in this paper. The focus is…

Normal Curve Equivalents (NCEs), a new score system for standardized tests, are used by school districts in reporting results to federal funding agencies. The author uses a quiz format to answer questions on the use of NCE scores. (EGS)

It is argued that consequential validity is a concept worth considering. The solution to defining "validity" is not to narrow the concept, but to allow for the differential prediction provided by tests in different circumstances. Consequences of the uses and interpretations of test scores are central to their evaluation. (SLD)

The development and validation of professional development resource materials for teachers by the National Council on Measurement in Education and associated professional groups is described. The developed module contains a context-orienting vignette, instruction, practice exercises, hands-on experiences, small group topics, and homework problems.…

The unfulfilled promise of criterion-referenced measurement is that it would permit valid inferences about what a student could and could not do. To come closest to achieving all that criterion-referenced testing originally promised, tests of higher item density, with more items per amount of domain, are required. (SLD)

The term "criterion-referenced measurement" has been so frequently used that accumulated surplus meaning has sometimes swamped the fundamental concept. Stripping away extraneous interpretations affirms the contemporary relevance of the concept. Substituting the term "construct-referenced" underscores the need for better…

The instructional impact of criterion-referenced testing during the past three decades is reviewed, and a method of devising criterion-referenced tests is suggested that departs from the usual model. Adding verification along the lines of panel review that newly constructed test items do elicit appropriate information is suggested. (SLD)

This article presents a model that can be used by local school districts for reanalyzing standardized test results to obtain a more valid assessment of local learning objectives can be used to identify strengths/weaknesses of existing programs as well as individual students. (EGS)

The University of Tennessee, Knoxville conducted a system-wide effort to increase use of student outcome information in assessing and improving academic programs. For this effort, the university received the National Council on Measurement in Education award for an outstanding example of an application of educational measurement technology. (EGS)

A scenario and accompanying questions and answers are posed to help educators examine possible problems in interpreting a student's test score profile. Profiles developed and used soundly are very helpful, but possible pitfalls in test interpretation must be recognized. (SLD)

An expanded framework for validating tests is needed to include the perspectives of teachers and students as well as of test makers and scientists. The development of educational assessments must take place within an understanding of how tests are used in context. (SLD)

Incidents affecting the implementation of large-scale testing programs are described to illustrate associated problems. Issues addressed include creation of test materials, preparation of answer documents, transportation of test materials, scoring and analysis of tests, and dissemination and utilization of test results.
