WA HB1450

Establishes state policy allowing four-year-olds to enroll in public school "transition to kindergarten" programs if they need additional kindergarten preparation or live in extreme child care access deserts without access to other early learning programs

Requires Office of Superintendent of Public Instruction (OSPI) to limit and regulate approved sites, prioritizing areas classified as extreme child care access deserts, with schools needing advance approval before enrolling state-funded children

Mandates collaboration verification from child care resource and referral organizations to ensure programs do not adversely impact regional early learning providers like Head Start, ECEAP, and licensed child care centers

Caps statewide enrollment funding at 2023-24 school year levels and explicitly states funding is not part of basic education under the state constitution

Declares the act an emergency measure taking effect immediately, amending RCW 28A.300.072
