Funding

How Pennsylvania funds schools

Pennsylvania funds districts through Basic Education Funding layered on heavy local property-tax reliance, distributed by a student-weighted fair funding formula (2016) that accounts for poverty, English learners, charter enrollment and local wealth. After a 2023 Commonwealth Court ruling found the system unconstitutional, the state added an adequacy supplement — about $494 million in 2024–25 directed to the most underfunded districts — as a first step toward closing a multi-billion-dollar adequacy gap.

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

Accountability

Report card & state results

Pennsylvania’s accountability dashboard is the Future Ready PA Index, covering state-assessment performance, academic growth (PVAAS), English-language progress, regular attendance, the Career Standards Benchmark and graduation rate. Look up Ridley SD on the Future Ready PA Index.

Accreditation

Accreditation status

Pennsylvania does not require accreditation of its public districts; the State Board of Education and Department of Education oversee them directly, while voluntary accreditation through Middle States or Cognia is used mainly by private and charter schools. Search the Middle States directory.
