Precocious Puberty, IQ and School Acceleration.

The paper presents the results of a survey on cases of idiopathic sexual precocity with reference to the relation between physical precocity, chronologic age, IQ and school grade level. The best sampling criterion was a diagnosis of idiopathic sexual precocity. Intelligence tests had been given to the patients over the years by four different people and put on file. The patients fall into three categories with respect to progress in school: (1) those for whom accelerated admission and/or skipping a grade was accomplished (12 cases); (2) those for whom early school admission or later acceleration was recommended, but either not accomplished or not subsequently reported (eight cases) and (3) those for whom school acceleration was not pragmatic and was not recommended (25 cases).
