Beta III

It is easy to administer and score and is useful for screening large numbers of people for whom administering comprehensive test batteries would be time consuming and costly. It is especially useful when assessing low-functioning or low skilled individuals. Beta III can be administered to groups or individuals.

Beta III is the latest revision of an instrument with a long and distinguished history. The original version was developed by the U.S. Army during World War I to assess the intellectual ability of illiterate recruits. In 1934, Kellogg and Morton revised it to make it suitable for civilian use. Beta III is an updated version of the Revised Beta Examination, Second Edition, Published in 1974.
