Arthur Sinton Otis, PhD is best known for the multiple choice intelligence tests he developed for the US Army. As a doctoral student under Lewis Terman in 1917 he developed the group-administered tests titled the Army Alpha (for literates) and the Army Beta (for illiterates). Dr. Otis developed it to improve cost and time efficiency as compared to one developed by Alfred Binet (1857?1911), which was individually administered. Given in multiple-choice format and administered in groups, 1.7 million World War I recruits took the Army Alpha test. The results were published in 1921 and included the relative performance of recruits of different national origins. - Wikipedia Otis-Lennon School Ability Test (OLSAT).
