Abstract
Form L of this test was given to 215 children of both sexes with a mean I.Q. of 62.2, mean C. A. of 14-2, and mean M.A. of 8-5. The test was continued with each child until complete failures were registered in 3 successive test levels. The writer concludes that "if a mental defective fails a whole test-level between the test-age groups IX-XII, the psychologist, in order to obtain the greatest accuracy, should examine the child through two complete age levels beyond the year in which he first fails all test items."
