1919–1921: about fifteen group tests for the youngest pupils

In June 1921 O. J. Johnson, a Minnesota doctoral student, surveyed the group tests for primary pupils. He dated the first extensive use to 1919, when Haggerty gave Delta 1 in the Virginia Public School Survey, and counted about fifteen examinations by the time he wrote [3]. The years and names below are as he lists them.
