Considerable research has examined the use of rapid guessing measures to identify disengaged item responses. However, little is known about students who rapidly guess over the course of several tests. In this study, we use achievement test data from six administrations over three years to investigate whether rapid guessing is a stable trait-like…

The discovery and characterisation of planets orbiting distant stars has shed light on the origin of our own Solar System. It is important that college-level introductory astronomy students have a general understanding of the planet formation process before they are able to draw parallels between extrasolar systems and our own Solar System. In…

Naomi Gafni, director of Research and Development, National Institute for Testing and Evaluation, Jerusalem, Israel, has devoted a substantial part of her career to the development of admissions tests and other educational tests and to the investigation of their validity. As such she is keenly aware of the complexities involved in this process.…

Meeting Science, Technology, Engineering, and Mathematics (STEM) workforce demands require students to have positive attitudes and persist through the STEM pipeline. There is limited research on reliable and valid instruments that measures non-cognitive skills towards all STEM fields. Tools that have been developed have mostly used traditional…

The findings of previous research into the compatibility of stakeholders' perceptions with statistical estimations of item difficulty are not seemingly consistent. Furthermore, most research shows that teachers' estimation of item difficulty is not reliable since they tend to overestimate the difficulty of easy items and underestimate the…

This special issue of "Assessment in Education" contains the type of debate needed about what Cizek (2015) calls a "… lingering flaw in the concept of validity…." Some practitioners might not agree that the current theory of validation is flawed. Specifically, the debate Jon Twing is referencing concerns the role of the…

Since Cronbach's (1951) elaboration of a from its introduction by Guttman (1945), this coefficient has become ubiquitous in characterizing assessment instruments in education, psychology, and other social sciences. Also ubiquitous are caveats on the calculation and interpretation of this coefficient. This article summarizes a recent contribution…

School climate is one of the significant factors determining educational achievement. However, the lack of instruments to measure it has complicated the study of this concept in Russia. We review the history of the study of the concept of "school climate," and we discuss approaches to how it can be defined. We describe the most widely…

Cognitive Diagnostic Assessment (CDA) is an alternative assessment which can give a clear picture of pupils' learning process and cognitive structures to education stakeholders so that appropriate instructional strategies can be designed to tailored pupils' needs. Coincide with this function, the Ordered Multiple-Choice (OMC) items were…

In this commentary, Mary James highlights two problems she deemed critical during her work exploring the relationships between assessment and learning in theory and practice. First, efforts to improve assessment for learning were not always successful either in improving performance or in other ways. Second, and this may be a reason for the first…

Foreign language aptitude is defined as one's potential to learn a second language. A language learner with higher aptitude is predicted to learn more, faster, and reach a higher level of proficiency. If this is the case, one way to validate the construct of aptitude and its measure is to conduct a validation study in which measures of aptitude is…

Purpose: This study examined the quality of English test items using psychometric and linguistic characteristics among Grade Six pupils. Method: Contrary to the conventional approach of relying only on statistics when investigating item quality, this study adopted a mixed-method approach by employing psychometric analysis and cognitive interviews.…

As the global development community shifts its focus from improving access to education to improving learning and instruction, the need for instruments that accurately measure student achievement in mathematics and meet technical standards is increasing. This paper explores the importance of collecting high-quality validity evidence that aligns…

A critical discussion of the assumption of uncorrelated errors in classical psychometric theory and its applications is provided. It is pointed out that this assumption is essential for a number of fundamental results and underlies the concept of parallel tests, the Spearman-Brown's prophecy and the correction for attenuation formulas as well as…

Brennan (Brennan, R. L., 2012) noted that users of test scores often want (indeed, demand) that subscores be reported, along with total test scores, for diagnostic purposes. Haberman (Haberman, S. J., 2008) suggested a method based on classical test theory (CTT) to determine if subscores have added value over the total score. According to this…
