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 Wechsler Individual Achievement Test (WIAT-4) is the latest iteration of a popular instrument that psychologists employ to assess academic achievement. The WIAT-4 authors make both pragmatic and measurement claims about the instrument. The pragmatic claims involve being useful for identifying individuals in certain academic achievement-related…

Math fluency (MF) is the ability to quickly and accurately solve simple math exercises. Proficiency in MF is one of the buildings of arithmetic achievement during school. However, so far only paper and pencil tests have been used to assess MF. In the current study, we present the BGU-MF (Ben-Gurion University Math Fluency) test, a new computerized…

Large scale international assessments depend on invariance of measurement across countries. An important consideration when observing cross-national differential item functioning (DIF) is whether the DIF actually reflects a source of bias, or might instead be a methodological artifact reflecting item response theory (IRT) model misspecification.…

This research is motivated by the perspective that when empirical studies and assessment frameworks inform each other, assessments can enrich science education and strengthen its connections to modern science. The research proposes a bioenergy competency assessment for science education. It uses an argument-based approach to validation. Multiple…

This research aimed to investigate animation-based achievement tests according to the item format, psychometric features, students' performance, and gender. The study sample consisted of 52 fifth-grade students in Samsun/Turkey in 2017-2018. Measures of the research were open-ended (OE), animation-based open-ended (AOE), multiple-choice (MC), and…

The goal of this study was to provide normative scores and examine the psychometric properties of the Math Computation subtest of the Wide Range Achievement Test--IV (WRAT-IV) for Mexican adolescents after the completion of junior high school. We group-administered this subtest to 1,318 first-year Mexican high school students. We then obtained its…

This study provides a comparison of the results of latent class analysis (LCA) and mixture Rasch model (MRM) analysis using data from the Trends in International Mathematics and Science Study -- 2011 (TIMSS-2011) with a focus on the 8th-grade mathematics section. The research study focuses on the comparison of LCA and MRM to determine if results…

Mathematical competency is related to performance in introductory statistics courses and may be a roadblock to successful course completion. We developed a new measure (Math Assessment for College Students, MACS) of basic mathematics skills that improves upon measures previously used in undergraduate settings. The MACS is freely available and…

This study determined the psychometric properties of the Economics Achievement Test (EAT) using Item Response Theory (IRT). Two popular IRT models namely, one-parameter logistics (1PL) and two-parameter logistics (2PL) models were utilized. The researcher adopted instrumentation research design. Four research questions and two hypotheses were…

PISA [Programme for International Student Assessment] will be in the news again this year. The 2018 results are due to be released at the end of 2019 and they usually generate media interest. This Rangahau Whakarapopoto is a research brief which outlines things to watch out for as you think about what the results might mean.

Validity is one of the psychometric properties of the achievement tests. To determine the validity, one of the examination is item bias studies, which are based on differential item functioning (DIF) analyses and field experts' opinion. In this study, field experts were asked to estimate the DIF levels of the items to compare the estimations…

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…

In Winter 2021-2022, the Nebraska Student-Centered Assessment System (NSCAS) assessments are administered in ELA and mathematics in Grades 3-8. In Spring 2021-2022, the NSCAS assessments are administered in English language arts (ELA) and mathematics in Grades 3-8 and in science in Grades 5 and 8. The purposes of the NSCAS assessments are to…

In Fall and Winter 2022-2023, the NSCAS assessments were administered in ELA and mathematics for grades 3-8. In Spring 2022-2023, the NSCAS assessments were administered in English language arts (ELA) and mathematics for grades 3-8 and in science for grades 5 and 8. The purposes of the NSCAS assessments are to measure and report Nebraska students'…
