How we connect content to standards

Every alignment badge is a claim. We owe you an honest explanation of how we make it. Our process is five steps: read the framework's requirement, find candidate content, verify the connection, mark how strong it is, and write down why.

For curriculum directors

We publish the rubric criteria, the source URL and version for every framework, and an audit-grade reasoning note on every link. Citations are first-class — Porter (2002), Webb (1997), and Achieve EQuIP.
