In the lead article, Davenport, Davison, Liou, & Love demonstrate the relationship among homogeneity, internal consistency, and coefficient alpha, and also distinguish among them. These distinctions are important because too often coefficient alpha--a reliability coefficient--is interpreted as an index of homogeneity or internal consistency.…

Because of difficulties with neuropsychological assessments for dementia in people with learning disabilities, professionals in clinical practice have relied heavily on carer interviews, one of the most widely used being the "Dementia Questionnaire for People with Learning Disabilities" (DLD-Evenhuis et al. 2006 "Dementia…

This study used generalizability theory to measure reliability on the Recognizing Effective Special Education Teachers (RESET) observation tool designed to evaluate special education teacher effectiveness. At the time of this study, the RESET tool included three evidence-based instructional practices (direct, explicit instruction; whole-group…

Teachers are thrown open to abundance of free text answers which are very daunting to read and evaluate. Automatic assessments of open ended answers have been attempted in the past but none guarantees 100% accuracy. In order to deal with the overload involved in this manual evaluation, a new tool becomes necessary. The unique superlative model…

For educational tests, it is critical to maintain consistency of score scales and to understand the sources of variation in score means over time. This practice helps to ensure that interpretations about test takers' abilities are comparable from one administration (or one form) to another. This study examines the consistency of reported scores…

The extant literature has largely ignored a potentially significant source of variance in multiple mini-interview (MMI) scores by "hiding" the variance attributable to the sample of attributes used on an evaluation form. This potential source of hidden variance can be defined as rating items, which typically comprise an MMI evaluation…

One of the most important considerations in designing clinical infant research studies is the selection of reliable and valid measurement procedures. Few measures of caregiver-child interactions have been studied with newborns, particularly premature infants. The main objective of this study was to examine psychometric properties of the National…

Direct Behavior Rating (DBR) has emerged as a useful assessment method to identify behavioral risk and monitor behavioral progress. The development of an online training module has provided an option for low cost training accessible to a wide variety of users at their convenience. Although evaluation of the DBR online training module has…

This study aimed to investigate the item "Response Time Fidelity scores" ("RTFs"), "KuderRichardson Reliability" ("KR[subscript 20]") and "Cronbach's Alpha Reliability" ("alpha") coefficients, calculate "KR[subscript 20]" coefficients with "RTFs" for 30 threshold…

The Implicit Association Test (IAT) is increasingly used in developmental research despite minimal evidence of whether children's IAT scores are reliable across time or predictive of behavior. When test-retest reliability and predictive validity have been assessed, the results have been mixed, and because these studies have differed on many…

Educational Testing Service (ETS), working with 21 U.S. law schools, evaluated the predictive validity of the GRE® General Test using a sample of 1,587 current and graduated law students. Results indicated that the GRE is a strong, generalizably valid predictor of first-year law school grades and that it provides useful information even when…

This paper reviews the most important public English examination (matriculation exam) that students take at the end of their secondary education in Bangladesh. The examination is known as the Secondary School Certificate (SSC), which is taken at the end of Grade 10 in the mainstream education in the country. The score of SSC English examination is…

The aim of this study was to examine whether there is a relationship between the spatial reasoning skills and mathematical thinking profiles of elementary school students. The quantitative method of descriptive survey model was used in the study. The sample of the study comprised 103 fourth grade elementary school students in Turkey. The…

The main purpose of this study was to conduct a validation analysis of student surveys of teaching effectiveness implemented at Bangkok University, Thailand. This study included three phases; survey development, a pilot study, and a full implementation study. Four sources of validity evidence were collected to support intended interpretations and…

Researchers and practitioners have questioned whether scoring procedures used with curriculum-based measures of writing (CBM-W) capture growth in complexity of writing. We analyzed data from six independent samples to examine two potential scoring metrics for picture word CBM-W (PW), a sentence-level CBM task. Correct word sequences per response…
