Aberrant behavior refers to any type of unusual behavior that would not be expected under normal circumstances. In educational and psychological testing, such behaviors have the potential to severely bias the aberrant examinee's test score while also jeopardizing the test scores of countless others. It is therefore crucial that aberrant examinees…

At the outset of his thoughtful and thought-provoking article, Haertel (this issue) clearly identifies the issue with which he will be dealing: The disjunct, or gap, in current approaches to evaluating the merits of a given test, between the intended uses of that test and the validity of its score-based interpretations. The author thinks that…

In his thoughtful focus article, Haertel (this issue) pushes testing experts to broaden the scope of their validation efforts and to invite scholars from other disciplines to join them. He credits existing validation frameworks for helping the measurement community to identify incomplete or nonexistent validity arguments. However, he notes his…

The author is deeply gratified by the commentators' thoughtful responses and finds almost nothing to disagree with in any of them. Each offers additional insights prompting further reflection. In drawing out just a few common themes, this brief rejoinder omits many important ideas from the individual contributions. As stated in his title, the…

Validation research for educational achievement tests is often limited to an examination of intended test score interpretations. This article calls for an expansion of validation research in three dimensions. First, validation must attend to actual test use and its consequences, not just score meaning. Second, validation must attend to unintended…

Educational achievement is a very important issue for parents, teachers, and the government. An accurate measurement plays a very important role in evaluating achievement fairly, and, therefore, analysis methods have been developed considerably in recent years. Education based on long-time learning processes forms a fruitful base for item tests,…

The rank-ordering method for standard maintaining was designed for the purpose of mapping a known cut-score (e.g. a grade boundary mark) on one test to an equivalent point on the test score scale of another test, using holistic expert judgements about the quality of exemplars of examinees' work (scripts). It is a novel application of an old…

"Linking" is a term given to a general class of procedures by which one represents scores X on one test or measure in terms of scores Y on another test or measure. A recent taxonomy by Holland and Dorans (2006; Holland, 2007) organizes the various types of links into three broad categories: prediction, scale aligning, and equating. In…

Newton's article (2010) makes three main contributions to the literature. First, it is transatlantic, bringing together literatures that have been dealing with similar problems, using sometimes different methods and certainly with distinctive educational, cultural perspectives. He points out that neither of these literatures has all of the…

Discusses evaluation of tests both in terms of their measurement properties and their potential social consequences. Presents a model for evaluating test validity based on empirical evidence as well as on ethical decisions. Stresses the importance of construct validity as a rational foundation for test predictiveness and relevance; and the…

Testing is a means of obtaining information about people and their status. Too often tests and testing govern us as educators rather than being governed by us. Reviews the problem and offers some suggestions. (Editor)

Measurement terms used in Title I evaluation are contained in this glossary. Several types of measurement techniques are identified and defined. Other measurement terms which are defined include those relating to validity, reliability, statistical analysis, test interpretation, and program effectiveness. (DWH)

Although agreeing that the System of Multicultural Pluralistic Assessment (SOMPA) has an important purpose, the author questions some perceived weaknesses: test validity; medical model measures; sociocultural scales; estimated learning potential (ELP); and the incompleteness of SOMPA manauls for use in evaluating the system. (See also TM 504 174).…
