The Kindergarten Readiness Act, signed into law in 2010 by Gov. Schwarzenegger, is a historic reform to kindergarten education that gives California an unparalleled opportunity to ensure that our state’s youngest children are better prepared to succeed in kindergarten and beyond. The Kindergarten Readiness Act, SB 1381 by Senator Simitian, created transitional kindergarten, the first year of a two-year kindergarten experience for those students who are born between September and December. It also changed the kindergarten entry date from Dec. 2 to Sept. 1, so children enter kindergarten at age 5. The law phases in the new age requirement by moving the cutoff date one month a year for three years, beginning in the fall of 2012.
