About the Kuhlmann-Anderson Tests
Most early American intelligence tests covered a narrow grade range. The Otis Primary covered grades 1-4; the Otis Advanced covered grades 4-8 and high school. The National Intelligence Tests covered grades 3-8. School districts that wanted to track cognitive development across the entire K-12 range had to use multiple incompatible tests.
The Kuhlmann-Anderson was designed to solve this by providing eight grade-specific tests, each with appropriately-leveled items but using a consistent scoring scale so that results could be compared across grades. The youngest level (grade 1) used picture items administered with examiner instructions; the higher levels were entirely paper-and-pencil multiple choice.
The Kuhlmann-Anderson was widely used in US schools through the 1940s and 1950s. It was particularly popular for longitudinal studies of cognitive development because of its uniform scoring scale across grade levels.

Kuhlmann had developed an earlier Binet revision (Kuhlmann 1922) used in clinical settings; the Anderson collaboration adapted it into a group-administered school test.
