Adaptive behavior scales are vital in assessing children and adolescents who experience a range of disabling conditions in school settings. This article presents the results of an evaluation of the design characteristics, norming, scale characteristics, reliability and validity evidence, and bias identification studies supporting 14…

The availability of psychometrically sound and usable universal screeners is a key component to successful early identification within a response-to-intervention model. The purpose of this study was to compare the diagnostic accuracy of oral reading fluency (ORF) and an informal reading inventory for identifying students considered at risk for…

Understanding students' learning dispositions has been a focus for research in education for many years. A range of alternative approaches to conceptualising and measuring this broad construct have been developed. Traditional psychometric measures aim to produce scales that satisfy the requirements for research; however, such measures have an…

For "Matter Changing" unit included in the Secondary School 5th Grade Science Program, it is intended to develop a test conforming the gains described in the program, and that can determine students' achievements. For this purpose, a multiple-choice test of 48 questions is arranged, consisting of 8 questions for each gain included in the…

The Centers for Disease Control have suggested that physical education plays a role in promoting healthy lifestyles. Prior research suggests a link between attitudes toward physical education and physical activity outside school. The current study provides additional evidence of construct validity through a validation across two instruments…

The scales for rating the behavioral characteristics of superior students (SRBCSS), which were developed by Renzulli and his colleagues, are considered the most widespread and the most important scales used in the identification of gifted and superior students. Recently, four new scales were added. The aim of this research was to examine the…

Teachers' attitudes and beliefs on classroom management contribute significantly to student learning and development. Despite its importance, research in this aspect, however, has still been stymied by the difficulty of measuring teachers' classroom management attitudes and beliefs. Psychometrically sound instruments to measure teachers' classroom…

Self-regulation has become a widely discussed subject in education as it facilitates learners' ability to master their own learning. The purpose of the present study is to examine the psychometric properties of self-regulation in second language learning via Rasch measurement. A total of 528 high-school students from an East Asian country…

Research indicates that educational, economic, and life success reflect children's nonacademic as well as academic competencies. Therefore, longitudinal surveys that assess educational progress and success need to incorporate nonacademic measures to avoid omitted variable bias, inform development of new intervention strategies, and support…

Initiatives to increase leadership accountability coupled with efforts to promote data-driven leadership have led to widespread adoption of instruments to assess school leaders. In this paper we present a decision matrix that practitioners and researchers can use to facilitate instrument selection. Our decision matrix focuses on the psychometric…

In psychometrics, it is difficult to verify that measurement instruments can be used to produce numeric values with the desirable property that differences between units are equal-interval because the attributes being measured are latent. The theory of additive conjoint measurement (e.g., Krantz, Luce, Suppes, & Tversky, 1971, ACM) guarantees…

The Career-Adaptabilities Scale (CAAS)--Portugal Form consists of four scales, each with seven items, which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from good to…

The Career Adapt-Abilities Scale (CAAS)--Korea Form consists of four subscales, each with six items. The subscales measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from…

The CAAS-France Form consists of four scales, each with six items, which measure concern, control, curiosity, and confidence as psychosocial resources for managing occupational transitions, developmental tasks, and work traumas. Internal consistency estimates for the subscale and total scores ranged from moderate to good. The factor structure was…

Reliability of test scores is one of the most pervasive psychometric concepts in measurement. Reliability coefficients based on a unifactor model for continuous indicators include maximal reliability rho and an unweighted sum score-based omega, among many others. With increasing popularity of item response theory, a parallel reliability measure pi…
