Provides that regional school districts are not subject to State school aid reductions under certain circumstances.

This bill prevents certain New Jersey school districts from facing state aid reductions during the 2019-2025 school years. It specifically exempts regional school districts and high-need districts (SDA districts) meeting certain criteria - such as having above-average local tax rates, spending below adequacy levels, or meeting administrative cost benchmarks - from annual aid cuts. Districts with a negative "State aid differential" (meaning they receive less state funding than needed) will instead receive aid equal to their prior year's amount plus a portion of any state aid increases. The bill also ensures regional districts created after 2021 receive the greater of their new regional funding or the combined prior funding of their constituent districts.
