Engrossed Substitute Senate Bill 6260 amends existing education statutes. It changes the school transportation vehicle reimbursement law (RCW 28A.160.200) by directing OSPI to set and annually revise a reimbursement and depreciation schedule based on vehicle category, anticipated life, and inflation; it establishes minimum useful lifetimes for certain bus categories beginning with depreciation payments scheduled as of September 2025 (120 months for category A, 180 months for categories C and D), requires reimbursements to be held in separate transportation vehicle funds, authorizes a financial penalty (a prorated deduction from future reimbursements) if districts fail to maintain or operate vehicles to OSPI standards, requires an annual straight-line depreciation schedule for private-carrier contracts, and temporarily reduces the reimbursement quote for zero-emission buses to 33 percent of the 2025–26 quote through 2027–28 while allowing final depreciation payments to be based on lowest zero-emission bids. The bill continues and renames transitional kindergarten as the "transition to kindergarten program" (RCW 28A.300.072), clarifying it is not part of the state’s statutory basic education program and directing OSPI to adopt rules for administration, funding allocation, and minimum program standards. It requires prioritization criteria (including prioritizing existing programs that serve low-income, special education, and multilingual learners before opening new slots in areas DCYF designates as extreme child care access deserts), eligibility and enrollment rules (children must be at least four by August 31 and be determined to benefit), program data reporting and student identifiers, a local child care needs assessment before expansion, OSPI–DCYF collaboration on best practices and site visits, and allows sliding-scale fees with specific exceptions. Funding is limited to amounts in the omnibus appropriations act, is allocated by two specified formulas, counts transition-to-kindergarten children as kindergarten students for certain funding calculations, and requires OSPI to report annually beginning June 30, 2026, on slot allotments and local indicators. The act also amends related funding and program statutes: it reenacts/clarifies state local effort assistance for enrichment levies (RCW 28A.500.015) and maintains National Board certification bonus provisions (RCW 28A.405.415). It amends running start funding rules (RCW 28A.600.402) to authorize up to 10 college credits per student per summer term, permit averaging September–June enrollment for funding, require annual OSPI reporting on combined FTE experience, and changes the allowed combined FTE enrollment limits for running start students; the extracted text shows conflicting provisions (one amendment sets a 1.2 FTE maximum, another sets 1.4 FTE generally and 1.3 FTE for 2026–27 and 2027–28) and portions of these sections are truncated. Important provisions, including full funding language for the transition to kindergarten program, subsection (7) regarding charter school participation, the final resolution of the running start FTE limit, and the text amending several other cited RCWs, are missing from the extracted material.

If enacted, school districts and educational service districts would see state bus replacement payments become more prescriptive and slower to accumulate: OSPI must assume longer minimum useful lives for many buses (120 months for category A, 180 months for C and D beginning with depreciation schedules as of September 2025), revise reimbursement rates at least annually, and hold reimbursements in separate transportation vehicle funds; districts that fail to maintain or operate buses to OSPI standards risk future reimbursement deductions. Zero-emission buses would be quoted at only 33 percent of the usual reimbursement for the 2025-26 through 2027-28 school years, which likely increases local costs or the need for other funding sources, and OSPI will set straight-line depreciation schedules for privately contracted carriers. The transition to kindergarten program would only grow to the extent the legislature funds it in the omnibus appropriations act and allocations would be distributed by OSPI using two specified formulas, with children in the program counted as kindergarten for funding and special education calculations; OSPI must also prioritize slots, require local needs assessments, adopt program rules, and begin annual slot-allotment reporting to the governor and legislature starting June 30, 2026. This shifts new administrative and reporting duties onto OSPI and participating districts/charter/compact schools, who must adopt eligibility, assessment, and enrollment policies and may charge sliding-scale fees except for certain low-income and special education children; however key funding details and charter participation rules are missing from the text provided, and separate portions of the bill give conflicting running-start FTE caps (1.2 versus 1.3/1.4) and conditional effective dates tied to another bill, so the final limits on running-start funding and some funding specifics remain unclear.
