Last year, a kindergarten-teacher friend and I were talking about the opening days of school. Maybe I should have waited until next year. Maybe this child should have waited another year. Regulations regarding kindergarten entrance age vary throughout the United States because each state determines its own rules.
Many children enter kindergarten at age five.
Some children enter at age six. And some children are still four. A few states, including Connecticut, enroll children in September who will reach their fifth birthday on or before January 1 of the next year. And the developmental age span is even greater. The official school age, the legal age at which children must be educated, is often different from the kindergarten entrance age.
