Funding

How New Jersey funds schools

New Jersey funds districts through the School Funding Reform Act (SFRA), which calculates a weighted adequacy budget — a base per-pupil cost plus weights for at-risk, English-learner, combination and special-education students — then determines each district’s local fair share and fills the rest with equalization aid. The multi-year S2 law finished rebalancing aid toward under-funded districts in 2024–25.

District-level per-pupil spending and the local/state/federal revenue split for South Plainfield School District are published in the federal school-finance files — see the full-data links below for the current figures.
