Much of the recent focus of educational policymakers has been on improving the measurement of teacher effectiveness. Linking student growth to teacher effects has been a large part of reform efforts. To date, neither researchers nor practitioners have arrived at a consensus on how to treat test scores from students with disabilities in…

An effect size of about 0.70 (or 0.40-0.70) is often claimed for the efficacy of formative assessment, but is not supported by the existing research base. More than 300 studies that appeared to address the efficacy of formative assessment in grades K-12 were reviewed. Many of the studies had severely flawed research designs yielding…

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…

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…

In this commentary, we summarize some of the main themes of the NRC report and note ways in which the papers by Mislevy and Haertel, Gorin, and Abedi and Gandara address the Panel's recommendations. We then briefly review and offer reflections on each paper. We see much to applaud here and also in the broader effort to build bridges between the…

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…

Studied the actual classroom assessment and grading practices of secondary school teachers in relation to a specific class and determined whether meaningful relationships existed between teacher practices and grade level, subject matter, and ability levels of students. Analysis of surveys completed by 1,483 teachers shows that most secondary…

Responds to a negative evaluation of the National Assessment of Educational Progress (NAEP) by the National Academy of Sciences (NAS) and asserts that a review of the evidence for the NAEP performance standards indicates that there is support for the current approach to NAEP standard setting. Considers the scholarship of the NAS evaluation…

Takes issue with support of the standard setting process of the National Assessment of Educational Progress (NAEP) advanced by critics of the evaluation of the standard setting process by the National Academy of Sciences and asserts that the achievement level descriptions developed for the NAEP no longer adhere to policy statements defining the…

Discusses the ways new technology, in partnership with advances in cognitive and measurement science, will transform large-scale educational assessment. Focuses on high-stakes assessment, especially testing for educational admission. (SLD)

The relationships between ratings on the Idaho Alternate Assessment (IAA) for 116 students with significant disabilities and corresponding ratings for the same students on two norm-referenced teacher rating scales were examined to gain evidence about the validity of resulting IAA scores. To contextualize these findings, another group of 54…

This article presents the viewpoint that care must be taken to fit the specifics of a testing program to its intended purpose. Testing for diagnosing individual student learning and for school evaluation should not be confused. Statewide testing programs may provide evaluative information, but are inadequate sources of diagnostic information. (LMO)

Data from large-scale international studies for 13 countries indicate that U.S. students are clearly not the most heavily tested students on earth if one compares systemwide tests by their duration. In the United States, tests are much more likely to be of low consequence for the student. (SLD)

Points out areas in which aspects of assessment practice remain resistant to change: (1) evaluation of student achievement; (2) appropriate application of assessment innovation; and (3) preparation of educators in educational assessment. (SLD)
