The Prudhoe Cognitive Function Test (PCFT) directly measures the cognitive abilities of people with intellectual impairment. This study examined the relationship between this instrument and the Kaufman Brief Intelligence Test (K-BIT) and two shorter versions of the same scale. High correlations between the verbal and performance sections of the…

The assessment of vocational workplace-based qualifications in England relies on human assessors (raters). These assessors observe naturally occurring, non-standardised evidence, unique to each learner and evaluate the learner as competent/not yet competent against content standards. Whilst these are considered difficult to measure, this study…

Value-added evaluations use student test scores to assess teacher effectiveness. How student achievement is judged can depend on which test is used to measure it. Thus it is reasonable to ask whether a teacher's value-added score depends on which test is used to calculate it. Would it change if a different test was used? Specifically, might a…

This study assesses the psychometric properties of a newly tested self-report assessment tool for media literacy, based on the twelve new media literacy skills (NMLs) developed by Jenkins et al. (2006). The sample (N = 327) consisted of normal volunteers who completed a comprehensive online survey that measured their NML skills, media exposure,…

The Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) is the instrument of choice for assessing symptom severity in older children (i.e., 8-18 years) diagnosed with obsessive-compulsive disorder (OCD). The reliability and validity of this measure for use among younger children (i.e., 5-8 years of age), however, has never been examined.…

Aims: Childhood attention-deficit/hyperactivity disorder (ADHD) frequently persists into adulthood and continues to impair health-related quality of life (HRQL). Thus, it is important to have validated symptom and HRQL measures for assessing treatment outcomes in this population. The purpose of the current analysis was to assess test-retest…

There is a paucity of information surrounding maths anxiety levels in the British undergraduate student population, and, due to terminological issues, existing measures of maths anxiety may not be appropriate measures to use with this population. The current study, therefore, reports on the development and validation of a new maths anxiety scale.…

Background: The purpose of this study is to describe feasibility and test-retest reliability of the six-minute walking distance test (6MWD) and an adapted shuttle run test (aSRT) in persons with severe intellectual and sensory (multiple) disabilities. Materials and Methods: Forty-seven persons with severe multiple disabilities, with Gross Motor…

This article sets the stage for the description of a variety of approaches to test reviewing worldwide. It describes the importance of test reviewing as a protection of the public and of society and also the benefits of this activity for test users, who must choose measures to use in particular situations with particular clients at a particular…

Educators and policymakers envision the future of education in Egypt as enabling learners to acquire scientific inquiry and problem-solving skills. In this article, we describe the validation of a model for problem solving and the design of instruments for evaluating new teaching methods in Egyptian science classes. The instruments were based on…

The Vanderbilt Assessment of Leadership in Education (VAL-ED) is a multirater assessment of principals' learning-centered leadership. The instrument was developed based on the Standards for Educational and Psychological Testing. In this article, we report on the validity and reliability evidence for the VAL-ED accumulated in a national field…

As a result of this research, a quantitative model and a procedure have been developed to create an online mentoring effectiveness index (EI). To develop the model, mentoring and teaching effectiveness are defined, and then the constructs and factors of effectiveness are identified. The model's construction is based on the theory that…

Assessing school principal performance is both necessary and challenging. During the past five years, many states have begun using validated measures in summative assessments of novice principal competency as a basis for certification decisions. Although standardized tests are used for certification purposes, other types of assessments are being…

Recent insight into the underlying molecular and cellular mechanisms of fragile X syndrome (FXS) has led to the proposal and development of new pharmaceutical treatment strategies, and the initiation of clinical trials aimed at correcting core symptoms of the developmental disorder. Consequently, there is an urgent and critical need for outcome…

This is the second study to investigate the clinical use of the Parent-Instruction Game with Youngsters (PIGGY) which is a structured observation system derived from the Dyadic Parent-Child Interaction Coding System II (DPICS-II; Eyberg, Bessmer, Newcomb, Edwards, & Robinson, 1994) and the Behavior Coding System (BCS; Forehand & McMahon, 1981). In…
