Description

An intelligence assessment scale proposed by Arthur S. Otis that assigns absolute intelligence grades and age-adjusted brightness coefficients to estimate general intelligence and probable ultimate attainment.

Components

  • Otis Group Intelligence Scale Advanced Examination: ten tests, described as the oldest and perhaps most widely used group test: Arthur S. Otis's Advanced Examination is described as "The oldest and perhaps the most widely used of the group tests of intelligence", consisting of 10 tests each containing from 20 to 30 tasks, including following directions, opposites, disarranged sentences, proverbs, arithmetic, geometric figures, analogies, similarities, narrative completion and memory, suitable for grades 5 to 12. The Army Alpha examination is noted as based largely on the Otis tests. (Bell (1920))
