Assessment of specific learning disabilities (SLD) in educational settings is one important function of a school psychologist. The federal definition of SLD describes "underlying cognitive processing deficits" as part of the assessment criteria, that is also incorporated in several states' SLD eligibility criteria, that is difficult to…

Brennan noted that users of test scores often want (indeed, demand) that subscores be reported, along with total test scores, for diagnostic purposes. Haberman suggested a method based on classical test theory (CTT) to determine if subscores have added value over the total score. One way to interpret the method is that a subscore has added value…

Although content validity--how well each item of an instrument represents the construct being measured--is foundational in the development of an instrument, statistical validity is also important to the decisions that are made based on the instrument. The primary purpose of this study is to demonstrate how simulation studies can be used to assist…

Several large scale assessments include student, teacher, and school background questionnaires. Results from such questionnaires can be reported for each item separately, or as indices based on aggregation of multiple items into a scale. Interpreting scale scores is not always an easy task though. In disseminating results of achievement tests, one…

The Checklist for Autism Spectrum Disorder (CASD) completed by a psychologist (following standardized procedures integrating parent interview data, teacher report, and clinical observations) was compared with the CASD completed independently by mothers and teachers in 168 children with ASD and 40 with ADHD (1-12 years). The 30 CASD autism symptoms…

This research concerns the application of multidimensional item response theory (e.g., Reckase, 2009) to link not-quite-vertical scales across age/grade levels. The approach allows scores to be related across levels without requiring the assumption of a vertical scale. The multidimensional framework is applied to an English language proficiency…

In order to accurately assess the English language proficiency of special populations of English learners, student assessment programs must maintain the comparability of standard and modified assessment formats, allowing for equivalent inferences to be made across student classifications. However, given the typically small size of special…

This article illustrates five different methods for estimating Angoff cut scores using item response theory (IRT) models. These include maximum likelihood (ML), expected a priori (EAP), modal a priori (MAP), and weighted maximum likelihood (WML) estimators, as well as the most commonly used approach based on translating ratings through the test…

This study examined changes in China's college student fitness test batteries since its inception in 1954. Using the constant content comparison method, the testing components, testing items and related cut-off values, testing methods, testing results utility, and testing material distribution were examined to identify the salient trends. The…

The paper is based on the construction and evaluation of scientific creativity test devised for the senior secondary school students. It is an attempt that was made to evaluate validity, reliability and to determine the appropriate standards for the interpretation of the scores obtained from the scientific creativity test devised for science…

This article discusses regression effects that are commonly observed in Angoff ratings where panelists tend to think that hard items are easier than they are and easy items are more difficult than they are in comparison to estimated item difficulties. Analyses of data from two credentialing exams illustrate these regression effects and the…

The purpose of this study was to support the identification of Social, Academic, and Emotional Behavior Risk Screener (SAEBRS) cut scores that could be used to detect high-risk students. Teachers rated students across two time points (Time 1 n = 1,242 students; Time 2 n = 704) using the SAEBRS and the Behavioral and Emotional Screening System…

Purpose: This study reports the psychometric development of the Cantonese versions of the English Computerized Revised Token Test (CRTT) for persons with aphasia (PWAs) and healthy controls (HCs). Method: The English CRTT was translated into standard Chinese for the Reading--Word Fade version (CRTT-R-[subscript WF]-Cantonese) and into formal…

Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

The use of the Quality Rating and Improvement System (QRIS) to improve early childhood education program quality is based in part on assumptions that the quality of programs can be measured and that quality ratings are associated with meaningful differences in learning outcomes for children. This report reviews all of the state QRIS validation…
