Background/Context: Previous research in educational assessment has consistently emphasized the importance of reliability as a cornerstone of test quality. Traditional measures of reliability, such as test-retest and split-half reliability, offer a broad view of how internally consistent a measure is but overlook the variability in this internal…

Anxiety often co-occurs with autism spectrum disorder, yet there are few valid and reliable instruments for measuring anxiety in youth with autism spectrum disorder. This article describes the modification of the Pediatric Anxiety Rating Scale for youth with autism spectrum disorder and systematic psychometric evaluation in a well-characterized…

15q13.3 microdeletion syndrome causes a spectrum of cognitive disorders, including intellectual disability and autism. We aimed to determine if any or all of three cognitive testing systems (the KiTAP, CogState, and Stanford-Binet) are suitable for assessment of cognitive function in affected individuals. These three tests were administered to ten…

Universal screening of very early school-age children (age 4-7 years) is important for early identification of learning problems that may require enhanced learning opportunity. In this context, use of standardized instruments is critical to obtain valid, reliable, and comparable assessment outcomes. A wide variety of standardized instruments is…

Research suggests that executive function (EF) may distinguish between children who are well- or ill-prepared for kindergarten; however, little is known about the test-retest reliability of measures of EF for children. We aimed to establish a battery of EF measures that are sensitive to both development and individual differences across the…

The consistency by which shared abilities are assessed on three intelligence tests was investigated. Instruments under consideration include: the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale-Fourth Edition. A list of shared abilities and the subtests…

Tailored testing by Cliff's method of implied orders was simulated through the use of responses gathered during conventional administration of the Stanford-Binet Intelligence Scale. Tailoring eliminated approximately half the responses with only modest decreases in score reliability. (Author/BW)

Stability of performance on the Kaufman Assessment Battery for Children (K-ABC) and the Stanford-Binet Intelligence Scale: Fourth Edition (S-B:4) over a 1-year interval was examined with a sample of 28 nonhandicapped preschoolers. Each child was administered both tests in counterbalanced order and retested in 1 year with either the K-ABC or the…

The Slosson Intelligence Test (SIT) and the Stanford-Binet, Fourth Edition (SBIV) were administered to 95 elementary students referred because of either learning problems or potential giftedness. SIT scores predicted SBIV verbal scores more accurately than composite scores. Overall the SIT predicted SBIV scores better for students with learning…

A review of the technical data available on the 1972 norms edition of the Stanford-Binet demonstrates how inadequate these data are. The Stanford-Binet should not continue to be used in important decision making processes unless this weakness is corrected. (Author)

Arguments and prejudices against the use of individually administered intelligence tests are considered and compared with possible values that may be obtained. Cautions about test score interpretation are discussed. Implications of abolishing intelligence testing are considered and recommendations for effective testing policies are presented. (CTM)

Chicano and Amerindian vocabulary scale responses from the Stanford-Binet (LM) and Wechsler Intelligence Scale for Children were item-analyzed for 1,009 subjects. The response patterns differed both by ethnic group and test, as well as by age. The most common, and recurring, pattern found was "level-of-difficulty" gradient…

The several statistical methods described for detecting test bias in terms of various internal features of a person's test performances and the test's construct validity can be applied to any groups in the population. But the evidence regarding groups other than U.S. blacks and whites is either lacking or is still too sketchy to permit any strong…

TAILOR is a computer program that uses the implied orders concept as the basis for computerized adaptive testing. The basic characteristics of TAILOR, which does not involve pretesting, are reviewed here and two studies of it are reported. One is a Monte Carlo simulation based on the four-parameter Birnbaum model and the other uses a matrix of…
