Transitional Kindergarten Overview

Registration for Kindergarten and Transitional Kindergarten


In 2010, the California legislature passed the "The Kindergarten Readiness Act" (SB1381) which amended California Education Code (EC) (Section 46300, 48000 and 48010) to change the required birthday for admission to kindergarten and first grade and established a Transitional Kindergarten Program beginning in the 2012-2013 school year.  The intent of "The Kindergarten Readiness Act" is to ensure that children have the early experiences they need to help them succeed in school. 

In 2021, legislation was passed that requires any local education agency (LEA) operating a kindergarten to also provide a TK program for all four-year-old children by 2025–26. TK uses a modified kindergarten curriculum that is age and developmentally appropriate and based on California's Preschool Learning Foundations and Frameworks.

Los Gatos Union School District offers an International Baccalaureate Transitional Kindergarten program at Lexington Elementary School.

This program provides the following advantages:

  • World language and a global perspective
  • California state standards taught in a transdisciplinary way
  • Student-centered approach to learning where student agency is taught and valued
  • Inquiry based, differentiated instruction to meet a child’s developmental and academic needs
  • A curriculum that encourages the development of flexible thinking and prepares students to evaluate information critically 
  • The opportunity for students to explore their environment and learn about their world through play and relationships 


Children residing in the Los Gatos Union School District attendance boundaries who will turn 5 years old by September 1, 2023 will be eligible to attend Kindergarten beginning on August 17, 2023.  Children who turn 5 years old between September 2, 2023 and April 2, 2024, are eligible to attend Transitional Kindergarten beginning on August 17th.

Kindergarten and Transitional Kindergarten registration packets for the 2023-24 school year are available online. Proof of age (birth record/certificate, passport, baptism certificate OR affidavit of the parent, guardian, or custodian of the minor), proof of residency, and immunization records will be required to register. Only students with completed registration, as outlined in the enrollment checklist, will be enrolled.
