Appropriate interpretation of assessment data requires an appreciation that tools are subject to measurement error. School psychologists recognize, at least on an intellectual level, that measures are imperfect--that test scores and other quantitative measures (e.g., rating scales, systematic behavioral observations) are best estimates of…

A readily applicable procedure is discussed that allows evaluation of the discrepancy between the popular coefficient alpha and the reliability coefficient of a scale with second-order factorial structure that is frequently of relevance in empirical educational and psychological research. The approach is developed within the framework of the…

The development of proficiency in the practices used by scientists and engineers is considered an important student outcome of laboratory instruction. We developed tasks to assess students' use and development of selected scientific and engineering practices in the general chemistry laboratory using an adapted evidence-centered design approach.

This article describes the development and initial testing of the "Elementary Literacy Coach Self-Efficacy Survey", a new instrument designed and created to assess literacy coaches' efficacy for coaching-specific tasks. A synthesis of literature on literacy coaching tasks and experts in the coaching field were used to craft the…

Classical approach to test theory has been the foundation for educational and psychological measurement for over 90 years. This approach concerns with measurement error and hence test reliability, which in part relies on individual test items. The CTT package, developed in light of this, provides functions for test- and item-level analyses of…

Research suggests that kindergarten fine motor (FM) and visual motor (VM) skills predict later school performance. Being able to identify if gaps exist in FM/VM readiness could inform FM/VM programming in the early years. The Early Development Instrument is used to assess school readiness in Canada and other countries. Through a Delphi method, a…

It is written for measurement professionals and administrators to help evaluate the quality of MAP Reading Fluency. The seven sections of this report: (1)…

Was the approach proposed for calculating exam grades in summer 2020 fair? Were the grades eventually awarded (after policy changes) fair? What is a fair arrangement for 2021? These questions have been at the heart of debate in the UK in the light of COVID-19. After schools were closed in the spring of 2020 and the decision was made not to proceed…

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.

Reliability is a measure of consistency. It is the degree to which student results are the same when they take the same test on different occasions, when different scorers score the same item or task, and when different but equivalent tests are taken at the same time or at different times. Reliability is about making sure that different test forms…

Teachers need to assess their students' current level of mathematical understanding to provide appropriate interventions for students who are struggling. Several school districts in Georgia currently use two assessments for this purpose--the Global Strategy Stage (GloSS) and the Individual Knowledge Assessment of Number (IKAN). The IKAN is…

The test view is on the Duolingo English Test (DET), an alternative online English proficiency test with a machine-driven characteristic. The review covers essential information of the DET such as test purpose, usage, score-mapping with CEFR scale, price, and publisher. Meanwhile, the test usefulness is discussed with focuses on reliability,…

In Japanese secondary schools, speaking assessment in English classrooms is designed, conducted, and scored by teachers. Although the assessment is intended to be used for summative and formative purposes, it is not regularly or adequately practiced. This paper reports the problems (i.e., lack of continuous speaking assessment, limited speaking…

Reading scores exist for a continuum of purposes, from informal assessment to formal standardized tests. This brief aims to answer the question: What matters most for elementary-grade teachers when thinking about reading scores, and what could policymakers do to help teachers? Three positions worth pursuing in this regard are shared: (1) every…

The Classroom Strategies Assessment System-Observer Form (CSAS-O) is a classroom observational system that combines direct observations and rating scales to assess teacher instructional and behavioral management practices, inform goals, plan professional development interventions, and monitor progress. CSAS-O Strategy Rating Scales yield scores…
