Requires full-day kindergarten in all school districts and establishes uniform age requirement for enrollment in kindergarten.

New Jersey's A4647 requires all public school districts to provide full-day kindergarten programs, with implementation deadlines based on district classification (A/B/CD/DE districts by 2020-2021, others by 2021-2022). It establishes a uniform age requirement: children must be five years old by October 1 of the school year to enroll in kindergarten, replacing current district-specific cutoffs. The bill amends existing education statutes (N.J.S.18A:38-5 and N.J.S.18A:44-2) to mandate these changes. This directly affects all New Jersey public school districts and kindergarten students entering school.
