A non-verbal performance test of intelligence, useful with language and hearing impaired individuals

  • Age Range: Developmental age 3-19 years
  • Time: Up to 40 minutes, individual administration

The Kohs Block Design Tests, published by Stoelting, are performance tests, standardized to measure intelligence for individuals with developmental ages 3-19. Its easy-to-give-and-understand instructions were designed to be given in pantomime, so the tests are especially valuable for testing those with language and hearing handicaps.  In addition, the Kohs Block Design Test has been used extensively in research, when an efficient measure of executive functioning skills is desired that is relatively language free.

The Kohs is particularly suited for use with disadvantaged and non-English speaking individuals, whose language deficits may mask underlying cognitive potential. Block design tests are significantly less affected by school training than Binet, yet possess a high degree of correlation and reliability. The test, which has shown a universal appeal to children, and even adults, consists of 16 colored cubes and 17 cards with colored designs, which the subject is to duplicate.

Complete Kohs Blocks Design Test includes Cubes, Cards, Manual and 50 Record Blanks.
