Summary
Educational accountability, enabled by data collaboration
The challenge: a privacy-safe solution for joining data on educational degrees and financial outcomes.
The Department of Education sought to connect data about degrees with their financial outcomes, from data managed by the IRS.
The resulting insights would be useful to students and parents, but producing the data product involved significant individual data privacy risk.
A collaboration with Tumult enabled the privacy-protected solution, and College Scorecard now helps students and families be better-informed around degree and school choice.
