Transitional Kindergarten

Transitional Kindergarten (TK) is an option, but not mandatory, for children who have their fifth birthday between Sept. 2 and Dec. 2. All districts are required to offer a TK option, though not every school in the district is required to have its own TK class. To learn more about what your child's school district offers, please contact the district directly. You can look up appropriate contact information in the SCOE directory. If you are not sure what district your child is in, you can use this district lookup to find out.


Children are age-eligible for Kindergarten if they will be five years of age on or before September 1. This means that their district of residence must admit them at that age. However, school is not mandatory for a child until he or she turns six. More information on Kindergarten is available on this California Department of Education webpage.
