This survey sought information regarding the policies of school districts across the nation on entrance requirements to kindergarten and the first grade. The school systems were classified under four strata according to total enrollment size. The most frequently reported minimum entrance age for kindergarten was 5 years of age by December 1. For the first grade, the majority of districts set 6 years by December 1 as the minimum age; a few schools required, in addition, the completion of the kindergarten level. Exceptions to the rules are summarized by district in the study. Chronological age is the principal entrance criterion, with other factors such as sex, I.Q., and social maturity becoming more influential. Extensive tables list the district admission requirements and State laws that affect these admission standards. (LN)
