Thirty-two preschool children were administered the Cognitive Levels Test (CLT) to evaluate its temporal stability and concurrent validity. Results indicated good temporal stability for the CLT-Cognitive Index and high correlations between the CLT-Cognitive Index and the Stanford-Binet: Fourth Edition. (Author/JDD)

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…

WISC-III IQs and subtest scaled scores of 440 students with specific learning disabilities were examined for gender differences. Boys exhibited statistically higher Full Scale, Verbal, and Performance IQs than did girls, as well as higher scores on six of seven subtests. Girls outperformed boys only on the Coding subtest.

Rasch calibration procedures were applied to item-response data for the 1,262 infants and toddlers comprising the standardization sample for the Mental Scale of the Bayley Scales of Infant Development. Analyses tend to confirm the psychometric integrity of the instrument. (Author)

The Wechsler Preschool and Primary Scale of Intelligence-Revised, intended for children ages 3-7, is used to diagnosis exceptional intellectual ability in school settings. Its 12 subtests measure both Performance Intelligence Quotient and Verbal Intelligence Quotient. This paper describes the test's administration, summation of data,…

The Cognitive Levels Test, for use with ages 5-21, is designed as a quick cognitive assessment instrument with 4 subdomains: verbal reasoning, abstract reasoning, quantitative reasoning, and memory. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)

The Stanford Binet Intelligence Scale measures four areas of cognitive abilities (verbal reasoning, abstract/visual reasoning, quantitative reasoning, and short-term memory), providing a continuous scale for appraising cognitive development from age two to adult. This paper describes the test's administration, standardization, reliability, and…

This article describes the Comprehensive Test of Nonverbal Intelligence, an assessment designed to evaluate the intellectual ability of students ages 6 to 18.11 years for whom other mental ability tests are inappropriate or to enable comparisons between verbal and nonverbal intellectual ability. Its administration, standardization, reliability,…

This article describes the Kaufman Brief Intelligence Test, an assessment of intelligence for individuals ages 4 to 90. The test is designed for those circumstances in which a brief measure of intelligence will suffice and trained professionals may be unavailable for the assessments. Its administration, reliability, and validity are discussed.…
