Students who are not proficient in math are more likely to face negative long-term effects. In addition to adults with a lack of math skills facing a range of potential economic and mental health issues, the nation is also negatively impacted by a society of individuals who cannot contribute to the technological infrastructure. Project-based…

The purpose of this study was to examine the impact of positive behavior interventions and supports for students with disabilities on school campuses compared to campuses that do not utilize PBIS. Specifically, the researcher sought to determine if campuses implementing PBIS impact students with disabilities academic performance on STAAR Reading,…

We investigated the ecological validity of performance measures from a computer-based assessment tool that utilises scripted video vignettes. The intended purpose of this tool is to assess the maintenance and repair skills of automotive technician apprentices, complementing traditional hands-on assessment formats from the German journeymen's…

Despite agreement about the central importance of validity for educational and psychological testing, consensus regarding the definition of validity remains elusive. Differences in the definition of validity are examined and reveals that a potential cause of disagreement stems from differences in word use and meanings given to key terms commonly…

Two experiments examined the dual influence of mind wandering (MW) on the incubation of both deliberate and spontaneous modes of creativity. Specifically, using a modified version of Sustained Attention Response Task as the incubation task, this study assessed whether taking a break from a creative task and engaging in either an MW-allowed task or…

The Wechsler Intelligence Scale for Children's (WISC) factorial\theoretical structure has undergone numerous substantive changes since it was first developed, and each of these changes has subsequently been questioned by assessment experts. Given remaining questions about the structure of the latest revision, the WISC-V, the present study used…

The use of unidimensional scales that contain both positively and negatively worded items is common in both the educational and psychological fields. However, dimensionality investigations of these instruments often lead to a rejection of the theorized unidimensional model in favor of multidimensional structures, leaving researchers at odds for…

The chapters in this online volume comprise the TIMSS & PIRLS International Study Center's technical report of the methods and procedures used to develop, implement, and report the results of TIMSS 2019. There were various technical challenges because TIMSS 2019 was the initial phase of the transition to eTIMSS, with approximately half the…

Purpose: This study introduces a framework to produce very short versions of the MacArthur-Bates Communicative Development Inventories (CDIs) by combining the Bayesian-inspired approach introduced by Mayor and Mani (2019) with an item response theory-based computerized adaptive testing that adapts to the ability of each child, in line with…

The authors evaluated measurement-level, factor-level, item-level, and scale-level revisions to the "Gifted Rating Scales-School Form" (GRS-S). Measurement-level considerations tested the extent to which treating the Likert-type scale rating as categorical or continuous produced different fit across unidimensional, correlated trait, and…

The underrepresentation of English learners (ELs) in gifted and talented programs is a societal and research problem that merits investigation. Three state departments of education and their state directors of gifted programs supported our access to 16 schools across nine districts. In these three states with gifted identification and programming…

Rapid response behaviour, a type of test disengagement, cannot be interpreted as a true indicator of the targeted constructs and may compromise score accuracy as well as score validity for interpretation. Rapid responding may be due to multiple factors for diverse populations. In this study, using Programme for International Student Assessment…

Comparing group is one of the key uses of large-scale assessment results, which are used to gain insights to inform policy and practice and to examine the comparability of scores and score meaning. Such comparisons typically focus on examinees' final answers and responses to test questions, ignoring response process differences groups may engage…

ACT requested assistance from the National Center for the Improvement of Educational Assessment (Center for Assessment) to investigate declines of scores for states administering the ACT to its 11th grade students in 2018. This request emerged from conversations among state leaders, the Center for Assessment, and ACT in trying to understand the…
