OpenDecisions (Open Decisions Graph)

OpenDecisions is equivalent of nutrition labels for education decisions: a public, open dataset and schema that turns scattered, un-auditable college data into comparable, citeable, uncertainty-aware labels, so students, counselors, and builders can make better choices without false precision or black boxes.

This site is the documentation for the OpenDecisions schema (v1), API, and prototype. Whether you're evaluating the project, building on it, or integrating the API, start with the Overview for full context: the problem we're solving, who it's for, what we're building, and what we don't do.
