Technical difficulties and other unforeseen events occasionally lead to incomplete data on educational tests, which necessitates the reporting of imputed scores to some examinees. While there exist several approaches for reporting imputed scores, there is a lack of any guidance on the reporting of the uncertainty of imputed scores. In this paper,…

Students with significant cognitive disabilities present an assessment dilemma that centers on access and validity in large-scale testing programs. Typically, access is improved by eliminating construct-irrelevant barriers, while validity is improved, in part, through test standardization. In this article, one state's alternate assessment data…

Standardizing aspects of assessments has long been recognized as a tactic to help make evaluations of examinees fair. It reduces variation in irrelevant aspects of testing procedures that could advantage some examinees and disadvantage others. However, recent attention to making assessment accessible to a more diverse population of students…

In educational practice, for the evaluation and diagnosis of learning disabilities (LD), it is advisable to use standardized tests together with observation questionnaires. When observation questionnaires are used in the study of LD, Cohen's (1960) kappa coefficient (k) is frequently applied as a measure of agreement between two raters when they…

In the social sciences, evaluating the effectiveness of a program or intervention often leads researchers to draw causal inferences from observational research designs. Bias in estimated causal effects becomes an obvious problem in such settings. This article presents the Heckman Model as an approach sometimes applied to observational data for the…

Four major problem areas inhibit the standardized assessment of critical thinking (CT): (1) content validity; (2) construct validity; (3) technical jargon; and (4) background knowledge. Practical examples of framing multiple-choice items for assessment are suggested. In the area of content validity, new agreement about the definition of CT now…
