Technical difficulties occasionally lead to missing item scores and hence to incomplete data on computerized tests. It is not straightforward to report scores to the examinees whose data are incomplete due to technical difficulties. Such reporting essentially involves imputation of missing scores. In this paper, a simulation study based on data…

Current educational policies rely on educational assessments. However, the technical aspects of assessments are often unknown to policy makers, which is dangerous because sound assessment policy requires knowledge of the strengths and limitations of educational tests. In this article, we discuss the importance of informing policy makers of…

Items on test score scales located at and below the Proficient cut score define the content area knowledge and skills required to achieve proficiency. Alternately, examinees who perform at the Proficient level on a test can be expected to be able to demonstrate that they have mastered most of the knowledge and skills represented by the items at…

A particular trait of the educational system under socialist reign was accountability at the input side--appropriate facilities, centrally decided curriculum, approved text-books, and uniformly trained teachers--but no control on the output. It was simply assumed that it met the agreed standards, which was, in turn, proven by the statistics…

Students who are deaf or hard of hearing (SDHH) often use test accommodations when they participate in large-scale, standardized assessments. The purpose of this article is to present findings from the "Third Annual Survey of Assessment and Accommodations for Students who are Deaf or Hard of Hearing". The "big five" accommodations were reported by…

Substantial growth in the numbers of English language learners (ELLs) in the United States and Canada in recent years has significantly affected the educational systems of both countries. This article focuses on critical issues and concerns related to the assessment of ELLs in U.S. and Canadian schools and emphasizes assessment approaches for test…

Local assessment systems are being marketed as formative, benchmark, predictive, and a host of other terms. Many so-called formative assessments are not at all similar to the types of assessments and strategies studied by Black and Wiliam (1998) but instead are interim assessments. In this article, we clarify the definition and uses of interim…

The purpose of this paper is to define and evaluate the categories of cognitive models underlying at least three types of educational tests. We argue that while all educational tests may be based--explicitly or implicitly--on a cognitive model, the categories of cognitive models underlying tests often range in their development and in the…

Large data sets from a state reading assessment for third and fifth graders were analyzed to examine differential item functioning (DIF), differential distractor functioning (DDF), and differential omission frequency (DOF) between students with particular categories of disabilities (speech/language impairments, learning disabilities, and emotional…

Based on the results of a generalizability study of measures of teacher knowledge for teaching mathematics developed at the National Center for Research on Evaluation, Standards, and Student Testing at the University of California, Los Angeles, this article provides evidence that teachers are better at drawing reasonable inferences about student…

Assessments labeled as formative have been offered as a means to improve student achievement. But labels can be a powerful way to miscommunicate. For an assessment use to be appropriately labeled "formative," both empirical evidence and reasoned arguments must be offered to support the claim that improvements in student achievement can be linked…

In most large-scale assessments of student achievement, several broad content domains are tested. Because more items are needed to cover the content domains than can be presented in the limited testing time to each individual student, multiple test forms or booklets are utilized to distribute the items to the students. The construction of an…

In many school districts, the pressure to raise test scores has created overnight celebrity status for formative assessment. Its powers to raise student achievement have been touted, however, without attending to the research on which these claims were based. Sociocultural learning theory provides theoretical grounding for understanding how…

There is no agreement at present about the importance or meaning of the term "consequential validity." It is important that the authors of revisions to the "Standards for Educational and Psychological Testing" recognize the debate and relegate discussion of consequences to a context separate from the discussion of validity.…

Some of the challenges that test publishers face in constructing educational assessments that meet high technical quality as prescribed in the "Standards for Educational and Psychological Testing" (AERA, APA, NCME, 1999) are examined. Federal educational initiatives are used to illustrate demands on technical quality that challenge the efforts of…
