Universal Nonverbal Intelligence Test™

Description


The UNIT is a set of individually administered specialized tasks that measure cognitive abilities. Unique to the UNIT, both administration and item response formats are completely nonverbal. Test materials have been designed to be culturally and ethnically sensitive, making them ideal for use with students who may be disadvantaged by traditional language-dependent measures. The tests measure a broad range of complex memory and reasoning abilities, including both verbal (symbolic) and nonverbal mediation.Back to the top How to Use the Assessment
Examiners employ eight universal hand and body gestures to explain the tasks to examinees. Examiner demonstrations, sample items, corrective responses, transitional checkpoint items, and scored items that do not permit examiner feedback, aid the nonverbal administration process. Examiners may administer two, four, or all six subtests depending on the referral. The Abbreviated Battery consists of the first two subtests, takes about 15 minutes to administer, and is ideal for screening of cognitive functioning. The Standard Battery consists of the first four subtests, takes about 30 minutes to administer, and is ideal for eligibility and diagnostic decision making. The Extended Battery consists of all six subtests, takes about 45 minutes to administer, and provides the most in-depth diagnostic data of the three test batteries. Regardless of which battery is administered, the examinee will receive an equal number of reasoning, memory, symbolic, and nonsymbolic tasks.

UNIT can be scored by hand or scored with the UNIT Compuscore software. UNIT Compuscore provides professionals the option to quickly convert raw scores to derived scores, and allows for changes in confidence bands and significance levels. The narrative text report contains a text section that can be exported for word processing, and the program includes integrated help menus for ease-of-use.

The minimum system requirements for the UNIT are:
  • Microsoft® Windows 95/98/NT/2000/ME operating system
  • Pentium® Processor
  • 20 MB hard disk space (30 MB recommended)
  • 32 MB of RAM CD-ROM drive
Please note that this test includes manipulatives with small parts that may present a choking hazard for children under the age of 8. Do not allow the child to place any manipulative in their mouth. A trained adult examiner must always closely supervise the administration of the test and the use of manipulatives by children. Back to the top
