This article considers how a handicapping system should be devised for squash. It looks at the American scoring system, and whether it is possible to have a fair system of handicapping. We consider "fair" from a perspective of expected number of rallies won and probability of winning.

Purpose: The aim of the study was to address the reported inconsistencies in the relationship between objective acoustic measures and perceptual ratings of vocal quality. Method: This tutorial moves away from the more widely examined problems related to obtaining the perceptual ratings and the acoustic measures and centers in less scrutinized…

Background: There is paucity in availability of valid and reliable measures of psychopathology that can be routinely applied with an intellectual disability (ID) population in clinical practice. The psychometric properties of the Clinical Outcome Routine Evaluation-Learning Disabilities 30-Item version (CORE-LD30) are examined. Method: The…

Creativity tests, at best, measure only a small sliver of the whole of creative giftedness. These tests assess aspects of creative intelligence. But creativity is at least as much a conscious decision and even an attitude toward life as it is a traditionally defined ability. This article discusses how well-intentioned gifted educators may be…

In this ITEMS module, we provide a two-part introduction to the topic of reliability from the perspective of "classical test theory" (CTT). In the first part, which is directed primarily at beginning learners, we review and build on the content presented in the original didactic ITEMS article by Traub and Rowley (1991). Specifically, we…

Tests, especially high-stakes ones, occupy a prominent role in education and impact on students' personal and professional trajectory. Therefore, it is crucial that they are well understood. Enhancing understanding of the workings of tests requires a multidisciplinary approach, one that treats tests not only as assessment instruments, but also as…

Reporting confidence intervals with test scores helps test users make important decisions about examinees by providing information about the precision of test scores. Although a variety of estimation procedures based on the binomial error model are available for computing intervals for test scores, these procedures assume that items are randomly…

Measurement models need to properly delineate the real aspect of examinees' response processes for measurement accuracy purposes. To avoid invalid inferences, fit of examinees' response data to the model is studied through "person-fit" statistics. Misfit between the examinee response data and measurement model may be due to invalid…

Background: Assessment is an essential part of any learning process; however, it is often disliked by most students. A wealth of research is available on issues on assessment, such as washback effect and test anxiety, and yet we know little about what students conceive of assessment. The objective of this case study was to explore a group of…

Validity and reliability are among the most crucial characteristics of a test. One of the steps to make sure that a test is valid and reliable is to examine the bias in test items. The purpose of this study was to examine the bias in 2012 Placement Test items in terms of gender variable using Rasch Model in Turkey. The sample of this study was…

Detection of students' ability levels is one of the common aims in educational studies. Cognitive Diagnosis Modeling approach has been used recently for the purpose of ability level detection by defined Q-matrices. To evaluate students' strengths and weaknesses, determine their mastery skills, and design instructions and interventions in learning…

Evaluation on the foreign student's competence of Indonesian language is required to assess their achievement. This research aimed to identify the difficulty level of test instrument, analyze the difference of foreign students' competence for Indonesian language and to analyze the correlation of students' competence over various objective test…

Distractor analyses are routinely conducted in educational assessments with multiple-choice items. In this research report, we focus on three item response models for distractors: (a) the traditional nominal response (NR) model, (b) a combination of a two-parameter logistic model for item scores and a NR model for selections of incorrect…

In the current study, we examined how student characteristics and cognitive skills, differing levels of text complexity (cohesion, decoding, vocabulary, and syntax), and reading comprehension question types (literal, inferential, critical analysis, and reading strategy) affected different types of reading outcomes (multiple-choice reading…

This study provides preliminary evidence for reliability and validity of the Hawaii Early Learning Profile Strands 0-3 (HELP Strands 0-3), an assessment instrument for young children. First, the degree of interobserver agreement for a sample of representative HELP items was examined; results indicated that HELP scoring was dependable and…
