Sports performance testing is one of the most common and important measures used in sport science. Performance testing protocols must have high reliability to ensure any changes are not due to measurement error or inter-individual differences. High validity is also important to ensure test performance reflects true performance. Time-trial…

Objective: To measure test-retest reliability of the Stop-Signal Task (SST) and the Conners' Continuous Performance Test (CPT) in children with ADHD. Methods: 12 children with ADHD (age 11.46 plus or minus 1.66) participated in the study. Primary outcome measures were stop-signal reaction time (SSRT) for the SST and CPT's commission errors (%FP).…

Assessment of the overarching self-regulatory mechanisms, or executive functions, in any age group is challenging, in part due to the complexity of this domain, in part due to their dynamic essence, and in part due to the inextricable links between these central processes and the associated domain-specific processes, such as language, motor…

This paper presents an evaluation of Army job training development and testing practices, with a focus on Advanced Individual Testing. Information comes from intensive interviews with school instructors and from observations in the schools. Results indicate that some aspects of the Instructional Systems Development (ISD) model have been…

This study focused on the validation of Generalizable Reasoning Skills assessment instruments with students with disabilities in secondary vocational programs. Results indicated that student self-ratings, teacher ratings, and a performance test were internally consistent and precise measures of reasoning skills for some uses but that most…

The microcomputer has increased interest in performance testing, which samples what a person can do rather than what he or she knows. Conventional psychometric theory is based on knowledge tests, but in performance testing the unit of analysis is a trial, and it is unreasonable to assume that mean performance and interim correlations are…

Describes recent efforts of the Center for Research in Evaluation, Standards and Student Testing (CRESST) to evaluate authentic assessment methods, such as portfolios and performance tests. When comparing the merits of authentic versus multiple-choice testing, it is wise to consider validity, reliability, consequences, fairness, generalization,…

Issues pertaining to the quality of performance assessments, including reliability and validity, are discussed. The relatively limited generalizability of performance across tasks is indicative of the care needed to evaluate performance assessments. Quality control is an empirical matter when measurement is intended to inform public policy. (SLD)

The composite of Armed Services Vocational Aptitude Battery (ASVAB) subtests used to select applicants for entry-level training in Army clerical schools was evaluated by correlating composite scores with training performance scores. Comparisons were made between the multiple R for this optimal set of predictors and that for the composite of…

The use of the Wechsler Intelligence Scale for Children, Third Edition (WISC-III) and its interpretation in educational use are discussed. To measure intelligence, Wechsler believed one must measure the various aptitudes that contribute to the total behavior of the individual. The WISC-III has six verbal subtests and seven performance subtests.…
