The Kohs Block test, also known as the Kohs Block Design Test,[1] is a performance test designed to measure intelligence. The test taker must, using 16 colored cubes, replicate the patterns displayed on a series of test cards. Because the instructions are easily communicated, the test can be administered to language or hearing handicaps.[1]

The test was fleshed out by psychologist Samuel C. Kohs, around 1923,[citation needed] building on earlier and similar designs. As early as the 1930s, the Kohs Block Test was administered at the Ohio School for the Deaf,[2] and at other schools with special needs students.

It has been reported that the Kohs Block test is "an integral part" of some IQ tests.[3]

Although, there is a limitation in the scoring technique that is believed to prevent a more widespread use in a clinical setting.[4]
