Assessment is fundamental to school psychology, but its purpose has shifted from making predictions about children to improving outcomes for children. This commentary on the special issue focuses on screening and progress-monitoring decisions that can be used to solve student problems. We outline several psychometric and practical issues that…

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…

This paper describes the development and psychometric evaluation of the Self-assessment Practice Scale (SaPS), an instrument for assessing students' actions when engaged in self-assessment. Adopting a theory-driven approach, the SaPS was developed in line with the self-assessment process proposed by Yan and Brown ("Assess Eval High…

Home literacy activities influence children's emergent literacy progress and readiness for reading instruction. To help parents fulfill this opportunity, we developed a new Emergent Literacy Screener (ELS) and conducted 2 studies of its psychometric properties with independent prekindergarten samples. For Study 1 (n = 812, M[subscript age] = 54.4…

The aim of the present study was to examine the psychometric properties of a questionnaire adapted from Students' Motivation Towards Science Learning questionnaire developed by Tuan and colleagues, to assess motivation to learn science among Namibian Grade 12 students (N = 755). The overall reliability of the scores on the 19-item questionnaire…

Current instruments for assessing university students' statistics anxiety prevailingly emphasize the affective construct component. In order to unfold the construct in a more exhaustive and differentiated manner, a scale for measuring university students' worry, avoidance, and emotionality cognitions was developed. In two samples of education…

This article aims at proposing a new measurement to assess the effects of language learners' goal-setting behavior, as an alternative to the traditional open-ended questionnaire. This goal-setting instrument was carefully developed through three phases. In the first phase, an item pool was generated. In the second phase, a pilot study was carried…

This study focused on the development and psychometric evaluation of the 16-item Critical Musicality Scale (CMS). The participants in the study comprised (N = 118) secondary students (mostly 13 to 14 years old) from Singapore. Four factors of critical musicality were hypothesised and empirically tested. The full sample was used to conduct an…

The "Psychological Sense of School Membership" (PSSM) scale has been used for more than 20 years to measure students' sense of school belonging, yet its psychometric properties have had limited examination with pre-adolescent children. This study investigated the utility and psychometrics of the PSSM in three primary school samples from…

The purpose of this study was to examine the psychometric properties of the "Autism Program Environment Rating Scale" ("APERS"), an instrument designed to assess quality of program environments for students with autism spectrum disorder. Data sets from two samples of public school programs that provided services to children and…

This study describes the development and initial psychometric evaluation of a Recognizing Effective Special Education Teachers (RESET) teacher observation instrument. Specifically, the study uses generalizability theory to compare two versions of a rubric, one with general descriptors of performance levels and one with item-specific descriptors of…

The Strengths and Difficulties Questionnaire (SDQ) self-report form is a brief 25-item measure that assesses the psychological adjustment of youth. Although widely utilized as a screening tool, a lack of consistent psychometric evidence undermines the SDQ's utility as a sound diagnostic tool for all youth. This study focused on examining the…

The purpose of this study was to identify the factor structure of the Child Oral and Motor Proficiency Scale (ChOMPS) and to evaluate the psychometric properties, including internal consistency reliability, test-retest reliability, and construct validity as measured by convergent and known-groups validity. Principal component analysis with varimax…

In this study, the replicability of the factor structure of The School Liking and Avoidance Questionnaire [SLAQ] for Turkish preschool children and the psychometric properties of the scale were investigated. The SLAQ consists of 14 items and is used to assess children's emotional and behavioral participation in school based on children's…

Drawing valid inferences from modern measurement models is contingent upon a good fit of the data to the model. Violations of model-data fit have numerous consequences, limiting the usefulness and applicability of the model. As Bayesian estimation is becoming more common, understanding the Bayesian approaches for evaluating model-data fit models…
