The study aims to verify the validity and reliability of a set of tests for measuring Indonesian students' reading literacy achievement that has been developed by the Center for Language Strategy and Diplomacy Development as well as the Educational Assessment Center, two institutions under the auspices of the Ministry of Education, Culture,…

International large-scale assessments provide cross-national data on students' cognitive and non-cognitive characteristics. A critical methodological issue that often arises in comparing data from cross-national studies is ensuring measurement invariance, indicating that the construct under investigation is the same across the compared groups.…

Early diagnosis of children with reading disorders is essential for intervention and academic success. Many children with reading difficulties have a deficit in phonemic awareness. A web-based, group-administered screening vehicle, the Risk Factor Screen for Reading (RiFS-Reading), was developed to quickly identify students who are "At…

This study examined the psychometric properties of the Positive and Negative Affect Schedule for Children-Short Form (PANAS-C-SF) in a diverse sample of 15-year-olds in the United States [N = 4382]. Multiple measurement models, including a one-factor model, two-factor orthogonal and oblique models, a three-factor model (PA, Fear, and Distress),…

This study aimed to develop a comprehensive tool to assess underachievement in gifted students, incorporating input from parents, teachers, and students themselves. A total of 285 participants, including 95 gifted students, their parents, and teachers, were involved in the study. The results have revealed a four-factor structure for the Gifted…

The aim of the study is to develop an achievement test consisting of the questions in verbal intelligence games whose validity and reliability have been ensured and which are in accordance with the learning outcomes of the states of substance and knowing the properties of substance via the five senses taking place in the unit "Let's Know…

Disciplinary climate and opportunity to learn (OTL) are considered as effectiveness-enhancing factors that can improve mathematics achievement. In this study, we investigated whether the school-level aggregation of student-reported OTL could yield reliable and valid measures, and then explored the relationships among disciplinary climate, OTL, and…

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…

In the current study, we aimed to develop a reliable and valid scale to address individual cognitive load types. Existing scale development studies involved limited number of items without adequate convergent, discriminant and criterion validity checks. Through a multistep correlational study, we proposed a three-factor scale with 13 items to…

The "GRE"® Psychology test is an achievement test that measures core knowledge in 12 content domains that represent the courses commonly offered at the undergraduate level. Currently, a total score and 2 subscores, experimental and social, are reported to test takers as well as graduate institutions. However, the American Psychological…

There is a significant need for kindergarten entry assessments (KEA) that meet state education agency (SEA) requirements and are psychometrically sound measures of a broad range of school readiness domains such as language, literacy, math, science, executive function, and social-emotional skills. Research Findings: In this paper, we describe five…

The aim of this study was to develop a Scientific Process Skills Test (SPST) in the context of ''Matter and its Nature''. It was investigated whether there was a predictive effect of demographical features and participating out-of-school learning opportunities across the 7th and 8th grade students' Scientific Process Skill (SPS) levels.…

The challenge of correctly identifying gifted students is a critical issue. Gifted education in Puerto Rico is marked by insufficient support and a lack of appropriate identification methods. This study examined the reliability and validity of a Spanish translation of the "Gifted Rating Scales-School Form" (GRS) with a sample of 618…

Component Universe Score Profile analysis (CUSP) is introduced in this paper as a psychometric alternative to multivariate profile analysis. The theoretical foundations of CUSP analysis are reviewed, which include multivariate generalizability theory and constrained principal components analysis. Because CUSP is a combination of generalizability…

Existing instruments designed to measure mathematics attitudes were too long, dated, or assessed with only western samples. To address this issue, a shortened version of the Attitudes Toward Mathematics Inventory (short ATMI) which measures four subscales--;enjoyment of mathematics, motivation to do mathematics, self-confidence in mathematics, and…
