The author's interpretation of findings from the surveys conducted with the scale across several Indiana cities; no effect sizes or statistics are printed for these group differences.

"In the surveys already made, clear-cut differences have been found between "fast" and "slow" sections, between schools, both in the ability of the children attending them and in the amount of adjustment made by the schools to the capacities of the children, and between average school children and children in institutions."
