1933. On April 5, 1933, at the age of 9 years 10 months, G was again tested by Leta S. Hollingworth, perhaps as a class demonstration. He was then in Grade 7B and his IQ is recorded as 176 plus. The following comment is made:
Children of G's present age can no longer be reliably measured in terms of IQ by any existing test if they have previously scored above 185 IQ. . . . The IQ of 176 plus merely informs us that the test has begun to "run down" in his case. . . . Next time we test him we shall have to use a test scoring in points only, which will place him on the centile scale for adults. . . . His physical measurements correspond closely to the norms for boys of about 11 years.
1934. There is in the files a Stanford-Binet record of G taken by Leta s. Hollingworth, March 19, 1934. His age was then 10 years 10 months and he was in Grade 8B in P.S. 208, Brooklyn. He passed without error all the tests in the scale (Average Adult and Superior Adult).
Miscellaneous records. In the McElwee report already cited the following scores are recorded, on a variety of scales, covering a two-year period (1931-1933).
