The purpose of this study is to compare the teacher retention rates in public elementary and middle schools in Georgia that met or did not meet the academic performance component of Adequate Yearly Progress. The teacher retention rates were expected to be higher in schools that met the academic performance component of AYP and lower in the schools…

In this report, Joan Herman, director for the National Center for Research, on Evaluation, Standards, & Student Testing (CRESST) recommends that the new generation of science standards be based on lessons learned from current practice and on recent examples of standards-development methodology. In support of this, recent, promising efforts to…

Background/Context: There are few empirical studies exploring the alleged conflict between the No Child Left Behind Act (NCLB) and the Individuals with Disabilities Education Act (IDEA). Objective: The purpose of this study was to examine what impact the No Child Left Behind Act has had on students with disabilities. Research Design: Specifically,…

In this article, we introduce a person-fit statistic called the hierarchy consistency index (HCI) to help detect misfitting item response vectors for tests developed and analyzed based on a cognitive model. The HCI ranges from -1.0 to 1.0, with values close to -1.0 indicating that students respond unexpectedly or differently from the responses…

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 this commentary, the author addresses what is referred to as the deterministic input, noisy "and" gate (DINA) model. The author mentions concerns with how this model has been formulated and presented. In particular, the author points out that there is a lack of recognition of the confounding of profiles that generally arises and then discusses…

Rupp and Templin (2008) do a good job at describing the ever expanding landscape of Diagnostic Classification Models (DCM). In many ways, their review article clearly points to some of the questions that need to be answered before DCMs can become part of the psychometric practitioners toolkit. Apart from the issues mentioned in this article that…

This article traces quality assurance and evaluation (QAE) developments in Finnish compulsory schooling. The central question is this: Is there a Finnish model of QAE? We conclude that it may be a rhetorical overstatement to speak about a specific Finnish 'Model' of QAE in a strong sense. However, neither is it valid to conclude that what happens…

Opposes Holt's suggestion to eliminate testing; states that the evils he suggested are not inherent in testing but in test administration and interpretation. Supports material-imbedded tests using unobtrusive measures. (MH)

This paper illustrates how graphical analyses can enhance the interpretation and understanding of multidimensional item response theory (IRT) analyses. Examples of different graphical representations are presented, including item response surfaces, information vectors, and centroid plots of trait distributions. All graphs are intended to…

Discusses the relationship between statistics and measurement for educators and test developers in particular. Using both approaches can develop linear measures and provide further analyses of the developed measures. (SLD)

The assumptions underlying item response theory (IRT) models may be expressed as a set of equality and inequality constraints on the parameters of a latent class model. It is well known that the same assumptions imply that the parameters of the manifest distribution have to satisfy a more complicated set of inequality constraints which, however,…
