wide range intelligence test reliability and validity

This flexibility makes the RAIT a viable option for use in schools, juvenile and adult justice systems, clinical settings, and human resource and related industrial settings.

Print and digital versions are statistically equivalent-so you can confidently assess groups or individuals using a computer or traditional paper and pencil.

Administration and scoring are also available through PARiConnect this digital version allows you to administer the full battery (i.e., all seven subtests) or the abbreviated battery (i.e., crystallized and fluid subtests only) and automatically calculates a measure of effort.

Requires minimal reading skill and almost no motor coordination and visual-motor skill, reducing the complications that can occur when manipulated objects (e.g., blocks) are used to assess intelligence.

Designed to provide continuity of measurement across a wide age span.

Composed of seven subtests that assess crystallized intelligence, fluid intelligence, and quantitative aptitude or intelligence.Unlike many similar measures, the RAIT can be administered via computer. The RAIT is a rapid, reliable, and valid intelligence test designed for group or individual administration. While the test authors claim that the full range of subtests takes only 60–90 minutes (no more than 13 of the 15 subtests can be given to any one individual and in practice, probably only six or seven may beadministered in any particular testing situation), the actual testing time may be significantly greater than this, depending on individual circumstances.NEW!

It is, in this regard, both exhaustively comprehensive and concomitantly rather tedious and slow to administer, particularly when a detailed assessment is required.

The present fourth edition of the Stanford-Binet Intelligence Scale (Thorndike, Hagen & Sattler, 1986) is greatly advanced in design and construction over the previous Form L-M. Early versions of the instrument were concerned primarily with the prediction of school achievement and academic learning on the basis of an overall IQ score.

The Stanford-Binet Intelligence Scale has a long history of successful usage as the foremost psychometric instrument for the assessment of cognitive ability.
