Updating school district public bid limits.

SB 6263 updates Washington school districts' public bidding requirements for purchases. It raises the threshold for requiring competitive bidding from $40,000 to $75,000 for items like furniture and supplies, and increases the threshold for full public bidding from $75,000 to $150,000 for larger projects. The bill also requires school districts to target purchasing up to 1% of goods from prison labor programs (Class II inmate work) and allows a price preference for "Washington grown" food purchases. Exceptions include school buses, emergency repairs, and certain construction services like management or engineering.
