q1 · i? · associational · r1

This is the author's stated conclusion from the mass-testing results, offered as interpretation; the article reports no validity coefficient or formal comparison against teacher judgments, only the retarded/accelerated group patterns.

"The tests in the time of a few minutes reveal the ability of the several members of the class to do general school work almost as accurately as the teacher by general observation can determine it after many months of intimate acquaintance."
