A Pennsylvania 501(c)(3) nonprofit supporting the MaST Community Charter Schools — providing the facilities and stewardship that let great teaching happen.
Who We Are
The Isaac Newton Foundation supports the health, welfare, and educational interests of the Mathematics, Science & Technology (MaST) Community Charter Schools. Organized and operated exclusively for charitable and educational purposes, the Foundation acts as a financial and property-holding vehicle that helps build, maintain, and support learning environments tailored around STEM education.
What We Do
The Foundation carries out its mission largely through real estate and facilities management. It leases property to several campuses under the MaST umbrella — ensuring these schools have the physical infrastructure they need to operate. By acting as a supportive landlord and asset manager, the Foundation lets school administrators focus on curriculum and student success while it handles macro-level facility and financial needs.
Building, holding, and leasing the campuses where MaST students learn every day.
Maintaining property and managing resources so funds directly benefit the schools.
Supporting learning spaces purpose-built around mathematics, science, and technology.

Accountability
As an entity exempt from federal taxation under Section 501(c)(3), the Foundation submits an annual Form 990 to the IRS detailing its revenues, expenses, and assets. Its financial statements are audited by an independent accountant to ensure strict regulatory compliance and to verify that all activities directly benefit the affiliated public charter schools.
