Modifies conditions for regional school district use of property assessments as basis for apportionment of costs to participating municipalities.

This bill changes how regional school districts in New Jersey apportion costs (like school funding) among participating municipalities. It allows districts to base these costs partly or entirely on property assessments, rather than solely on student enrollment, but only if three conditions are met: all municipalities have recent property revaluations within five years of each other, or all have property valuation ratios above 90%, or all are within 5% of each other's ratios. This ensures property-based cost sharing is fair and accurate across municipalities. The bill directly affects local governments that participate in regional school districts.
