Transitional Kindergarten

To ensure that California children are better prepared to succeed in kindergarten and beyond, the Riverside County Office of Education (RCOE) is supporting districts in implementing the Kindergarten Readiness Act of 2010 (Senate Bill 1381).

The transitional kindergarten legislation changed the entry day for kindergartners depending on their birth month. Prior to 2012, children enrolling in kindergarten had to turn five (5) years old by December 2. The legislation changed the enrollment age to five (5) years old by September 1, so that all children enter kindergarten at or near the age of five. The law amended the state Education Code (EC 48000[a]) relating to kindergarten to create a “transitional kindergarten” program that uses a modified kindergarten curriculum that is age and developmentally appropriate for students born between September and December. Transitional kindergarten serves as the first year of a two-year program and will provide four-year-olds with fall birthdays an additional year of preparation before entering kindergarten.

The transitional kindergarten program was phased in over three (3) years and was fully implemented by the first day of the 2014-2015 school year and pursuant to California EC 48000(c)(3), transitional kindergarten will continue each school year thereafter.

  • Eligibility for Transitional Kindergarten – Children who have their fifth (5) birthday between September 2 and December 2 qualify to be enrolled in a transitional kindergarten program maintained by the local school district. This age-criterion for enrollment will continue beyond this school year.

The RCOE Transitional Kindergarten Network meets multiple times a year to continue collaboration between districts and teachers to support the continued development and refinement of transitional kindergarten programs across the county.
