Requires minimum geographic cost adjustment for school districts in all counties.

This bill requires New Jersey school districts in every county to receive a minimum geographic cost adjustment (GCA) of 1.0 when calculating state school aid. The GCA adjusts funding based on local costs, and this bill mandates it cannot fall below 1.0 for any county, ensuring all districts get at least the base funding level. It amends existing law to clarify that the commissioner must develop and update this adjustment every five years using census data, while maintaining the 1.0 minimum. This directly affects all public school districts statewide by guaranteeing a baseline funding level regardless of geographic cost differences. The bill focuses on the formula's structure, not specific outcomes or advocacy.
