The Student Data Privacy Consortium (SDPC) is the largest student data privacy initiative in the United States. Operated by the Access 4 Learning Community, it brings together schools, districts, state agencies, and edtech vendors to solve the practical challenge of student data privacy at scale.
At the heart of the SDPC is the National Data Privacy Agreement (NDPA) — a standardized contract template that sets clear expectations for how vendors handle student data. Version 2 of the NDPA was developed collaboratively by all 28 state alliances, covering both national baseline obligations and state-specific privacy requirements. When a vendor signs one alliance agreement, other districts in that state can subscribe to it without negotiating from scratch.
The numbers speak for themselves: since 2016, over 275,000 standard DPAs have been executed through the SDPC framework. The freely accessible SDPC Resource Registry at sdpc.a4l.org now hosts more than 130,000 signed agreements between over 12,000 schools and districts and more than 6,674 education application providers. The 28 state alliances collectively represent over 34 million students in approximately 10,000 districts.
For teachers and administrators, the SDPC registry is the fastest way to verify whether an app has a formal privacy agreement in place. We reviewed education apps in the SDPC ecosystem and selected 8 with strong privacy commitments, broad district adoption, and signed Data Privacy Agreements that schools can verify and subscribe to.

Our Verdict
Prodigy Math stands out with the strongest combined privacy stack: iKeepSafe COPPA and FERPA certifications, a 92% Common Sense Privacy score, and active SDPC agreements. For districts that want one math tool they can approve with confidence, Prodigy is the safest bet.
If budget is the deciding factor, Khan Academy Kids is 100% free, nonprofit-backed, ad-free, and has signed DPAs through multiple SDPC state alliances. For leveled reading with current events, Newsela maintains active SDPC agreements across numerous states.
IXL and BrainPOP are strong choices for schools that need comprehensive K-8 or K-12 coverage with formal SDPC data privacy agreements in place. Both have extensive district adoption and signed DPAs that other schools in their state alliance can subscribe to.
The SDPC Resource Registry at sdpc.a4l.org is your starting point for verifying any vendor. Search by state, vendor name, or content area to check whether an app has a signed agreement before adding it to your classroom. If your state has an SDPC alliance, joining it gives your district access to subscribe to existing DPAs without negotiating individually.
