Changes are occurring in the type and grade placement of content in mathematics and science in many high schools. Many attempts are being made to shift the methodology of learning from drill to discovery, as indicated by Mayor and Brown (1). Though these changes in content and methodology are occurring, the problem of providing for differences among students in rate of learning still exists. The recently formulated programs in modern mathematics, biology, chemistry, and physics require individualization of instruction, including acceleration whereby some students complete twelve years of school in less than twelve years.One means of bringing appropriate educational content and bright children together is to admit bright children to the first grade at a younger age than other children. Thus, the bright children are the youngest in their classes but do not skip any content. Worcester (2) found this procedure effective in the schools of Nebraska; Hobson (3) reported similar results in the schools of Brookline, Mass.; and Birch (4) drew the same conclusion in the schools of Pittsburgh, Pa.At present, most schools do not grant early admission to bright children, and skipping a grade during the elementary school years is rejected by most parents and educators. However, many school systems hold classes during the summer. Children in the elementary school who are in the upper half of their class in chronological age and who are also bright and high achieving may attend a summer session of a few weeks duration, acquire the essential content of the higher grade to be skipped, and enter the higher grade in the fall. This procedure was tested in the Racine Public Schools. Older bright secondgraders were accelerated to the fourth-grade, after a five-weeks summer session which met for five mornings each week. The results were excellent academically, emotionally, socially, and physically for the children (5, 6). The Racine Public Schools have now incorporated this procedure into their regular operating practice.Another widely-discussed means of accelerating pupils without skipping content is the nongraded classroom. In the nongraded elementary school, older bright children may be accelerated without attending school in the summer through completing two semesters of
