q1 · i? · review · r1

Annotated-list entry for the National Intelligence Tests, outgrowths of the Army Intelligence Tests prepared under National Research Council auspices by a committee of Haggerty, Terman, Thorndike, Whipple and Yerkes (chairman), for grades 3 to 8. The reliability judgment is the author's evaluative comment, not a printed coefficient.

"The General Education Board appropriated $25,000 for the standardization of these tests, and they are probably the most reliable of any group tests of intelligence. Each scale is furnished in five forms of equivalent difficulty."
