Comprehensive Test of Nonverbal Intelligence - Second Edition [CTONI-2]

Donald D. Hammill, Nils A. Pearson, J.Lee Wiederholt

The latest edition of the Comprehensive Test of Nonverbal Intelligence is a norm-referenced test that uses non verbal formats to measure general intelligence of children and adults whose performance on traditional tests might be adversely affected by subtle or overt impairments involving language or motor abilities. The CTONI-2 measures analogical reasoning, categorical classification, and sequential reasoniing, using six subtests in two different contexts:pictures of familiar objects and geometric designs.
Results are reported as standard scores, percentile ranks, and age equivalents, for ages 6 years through 90 years. The reliability coefficients of its composite are mostly in the .90s with a few in the high .80s. It correlates with most well known intelligence testing in the high .70s. Considerable other validity evidence is provided in the manual.
New features include:updated and enhanced overall look, all new normative data from 2007 and 2008, elimination of floor effects, expanded study of item bias, and new oral instructions for common non-English languages in the United States. Testing time is one hour on an individual basis.

Detroit Tests of Learning Aptitude - Primary - Third Edition [DTLA-P:3]

Donald D. Hammill, Brian R. Bryant

The DTLA-P:3 is a quick, easily administered test for measuring the general aptitude of young children. It is particularly useful with low-functioning school-age children ages 3-0 through 9-11. It comprises six subtests, measuring cognitive ability in areas such as language, attention, and motor abilities. Significant improvements include:

Pictures in the easel have been drawn in color to present a more appealing look to children.

Additional instructions have been provided for giving and scoring the digit sequences and design reproduction items.

Interpretation sections have been expanded.

Items have been validated by both exploratory and confirmatory factor analysis.

Administration is on an individual basis and should take 15 to 45 minutes.

Draw-a-Person Intellectual Ability Test for Children [DAP:IQ]

Cecil R. Reynolds, Julia A. Hickman

The Draw-A-Person Intellectual Ability Test for Children, Adolescents, and Adults (DAP:IQ) provides a common set of scoring criteria to estimate intellectual ability from a human figure drawing.
This flexible assessment is for use by psychologists, school counselors, and professionals working with special-needs populations. The DAP:IQ allows you to derive reliable, quantitative ability estimates by using the largest single collection of normative data on this task ever gathered. Psychometric data, including normative reference data, are provided for ages 4 years to 89 years and are based on a total sample of 3,090 individuals across the United States. The validity and utility of this test lie in the scoring system’s emphasis of concepts over artistic skill and motor coordination.
The collection of an HFD is easily standardized with a set of simple, easily understood instructions, and requires a very short period of time to administer, 10 to 12 minutes, individually or to a group.

Primary Test of Nonverbal Intelligence [PTONI]

David J. Ehrler, Ronnie L. McGhee

The Primary Test of Nonverbal Intelligence (PTONI) is a theoretically sound, research-based method of assessing reasoning abilities in young children, ages 3 years to 10 years. Psychologists, diagnosticians. special educators, speech-language pathologists, and other professionals can use this test to identify both severe intellectual deficits and superior cognitive intelligence; help estimate future school success based on family history, educational background, and personality traits; and study a wide range of researchable topics and issues.

The PTONI was normed on a culturally and ethnically diverse demographic sample. It is unbiased, quick, accurate, and cost-efficient. Testing takes approximately 5 to 15 minutes, on an indiviual basis.

The test format requires the child to look at a series of pictures on each page and point to the one picture that does not belong with the others. Early items measure lower order reasoning (e.g., visual and spatial perception). Later items measure higher reasoning abilities (e.g., analogical thinking, sequential reasoning, and categorical formulation). The child's performance is recorded as a standard score (called the Nonverbal Index), a percentile rank, and an age equivalent.

Slosson Intelligence Test - Revised [SIT-R3]

Richard L. Slosson. Revised by Charles L. Nicholson and Terry L. Hibpshman

This newly revised edition of the Slosson Intelligence Test - Revised (SIT-R3) remains a quick and reliable individual screening test of Crystallized Verbal Intelligence for ages 4 to 65 years. It now has adapted score sheets for scannable/electronic readers and the supplementary manual for the visually impaired and the blind is now inclusive of the SIT-R3 manual.
The new SIT-R3 is a multidimensional assessment tool which can be used for regular education testing populations and also for most special testing populations. The test questions and norms tables have not changed, so SIT-R3 users may continue to administer and score the SIT-R3 with the 1998 Calibrated Norms Tables as usual and just order the supplementary manual when testing these special populations. It is designed for use by teachers, psychologists, guidance counselors, special educators, learning disability instructors, and other responsible persons who often need to evaluate an individual's mental ability. Administer and score on an individual basis within twenty minutes.

Test of Nonverbal Intelligence - Fourth Edition [TONI-4]

Linda Brown, Rita J. Sherbenou, Susan K. Johnsen

The Test of Nonverbal Intelligence - Fourth Edition is a practical, easy-to-use, norm-referenced instrument that measures an individual's intelligence. The administration and response format are pragmatic with simple oral instructions, requiring test takers to answer only with simple but meaningful gestures such as pointing, nodding, or blinking. This test is ideal for those who have language, hearing, or motor impairments, or are not familiar with mainstream American culture.
The TONI-4 has two equivalent forms: Form A and Form B. Each form consists of 60 items, all of which are abstract/figural, i.e., void of pictures or cultural symbols. All items are arranged in easy-to-difficult order. Each item contains one or more of the eight salient characteristics: shape, position, direction, rotation, contiguity, shading, size, and movement. Easier items contain one or two characteristics while more difficult items contain several.
This edition is for ages 6 years through 89 years of age on an individual testing basis. Testing time is between 15 and 20 minutes.
