Schools do not lack data; they lack agreement between the systems that hold it. Backstage lays whatever a school already has — termly check-ins, grades, attendance, programmes — under the observation record and reads them together. One child, three sources, one coherent read: what we see, what it means, what we will do next.
Grades come along too — in their place: behind the story of a child's growth, never in front of it. Backstage asks resource questions of the same numbers:
Call it a gentle subversion, not a rebellion: the marks the system requires, finally serving the child's story. When a parent asks "but how is she doing compared to the class?", the page answers with the better question already open — here is where she is on her own journey, and here is what we're doing next.
