Adjusting enrichment levies and local effort assistance.

SB 5593 adjusts how Washington school districts calculate their maximum allowable enrichment levies (local property taxes for extra programs beyond state funding). It sets new limits based on student enrollment: $2,500 per student (adjusted for inflation) for districts with fewer than 40,000 students, and $3,000 per student for larger districts. The bill also modifies the calculation to account for local effort assistance, compliance adjustments, and cooperative agreements between districts. School districts must now get approval for their levy expenditure plans before voting on new levies.
