Highline's financial outlook remains stable due to steady student enrollment and past budget adjustments. The School Board held a work session on Wednesday, March 5 about the budget development process. The next steps for the 2025-26 budget include working with leaders on school and department budgets, additional board updates in April and May, final budget development and a public hearing in June before submission to OSPI.
