Reliability analysis of the group-test battery given to 566 school children, comparing the percentage of children passing each test at successive chronological ages. The author reports that certain tests "show so little discriminative capacity as group tests" and plans substitutes.

"In some instances, as in V, 4, Discriminating Colors, VI, 2, Mutilated Pictures, VII, 4, Tying Bow-knot, etc.—the tests show so little discriminative capacity as group tests, that the writer intends to find substitutes for them."
