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,…

This article suggests a graphic technique that uses P-P plots to show the extent to which two groups differ on two variables. It can be used even if the variables are measured in completely different, noncomparable units. The comparison is symmetric with respect to the variables and the groups. It reflects the differences between the groups over…

The generalized partial-credit model (GPCM) is used frequently in educational testing and in large-scale assessments for analyzing polytomous data. Special cases of the generalized partial-credit model are the partial-credit model--or Rasch model for ordinal data--and the two parameter logistic (2PL) model. This article extends the GPCM to the…

There is a growing body of literature linking curriculum based measurements and general outcome measures to state test outcomes. With an increasing focus on the early identification of students at risk for academic failure, the present study investigated the predictive validity of preschool early literacy general outcome measures (GOMs) in a low…

This report presents the findings from the second National Assessment Program--Civics and Citizenship, conducted under the auspices of the national council of education ministers, the Ministerial Council on Education, Employment, Training and Youth Affairs (MCEETYA). The National Assessment Program--Civics and Citizenship measures Year 6 and Year…

To determine the extent to which knowledge of evidence-based reading instruction and mathematics is assessed on licensure tests for prospective special education teachers, this study drew on information provided by Educational Testing Service (ETS), the American Board for Certification of Teacher Excellence, and National Evaluation Systems (now…

In this commentary, the authors discuss some of the issues regarding the use of diagnostic classification models that practitioners should keep in mind. In the authors experience, these issues are not as well known as they should be. The authors then provide recommendations on diagnostic scoring.

This paper provides an overview of Chinese government attempts to promote a revised school curriculum reflecting a more holistic approach to education under the banner of "suzhi jiaoyu" ("quality education"), and positions the policies in the Chinese historical, educational, social and economic context. While the push has…

This article examines major trends in testing and accountability reform in the United States over the past decade. The review covers the apex and decline of the national experimentation with a range of alternative assessments and the rise of test-based accountability as a central policy initiative. These trends signify that testing has become a…

In many states, standardized tests are used to hold schools accountable for student academic achievement. To motivate improvement in test scores, financial awards are given to teachers and administrators in schools that show the greatest gains. However, failure to adjust for initial conditions may put awards out of the reach of some schools and…

We investigated motivation for taking low stakes tests. Based on expectancy-value theory, we expected that the effect of student perceptions of three task values (interest, usefulness, and importance) on low stakes test performance would be mediated by the student's reported effort. We hypothesized that all three task value components would play a…

A Markov chain Monte Carlo (MCMC) method and a bootstrap method were compared in the estimation of standard errors of item response theory (IRT) true score equating. Three test form relationships were examined: parallel, tau-equivalent, and congeneric. Data were simulated based on Reading Comprehension and Vocabulary tests of the Iowa Tests of…

This article looks at the controversial starting of testing, its boycott, the subsequent years of protest and, in October 2008, the apparent end of key stage examining in England. It considers a possible alternative to the tests based on a project carried out at King's College London based on portfolio assessment.

The national certification tests and entrance examinations are the most important tests for proving the ability or knowledge level of a person. To accurately evaluate the professional skills or knowledge level, the composed test sheets must meet multiple assessment criteria such as the ratio of relevant concepts to be evaluated and the estimated…
