The idea

Evaluate how answers use approved school sources.

Classroom example

Ask a question with supporting text, a conflicting passage, and no answer. Check what the system cites and how it describes uncertainty.

Use this checklist for grounded learning platforms.

  • Inspect source permissions
  • Open citations
  • Test deletion and reindexing

Grounding makes evidence inspectable

An answer tied to a source gives a learner something to check. It does not guarantee that the source was interpreted correctly or that it supports every sentence in the answer.

Try it with your school

  • Ask a question with a known source passage.
  • Open the citation.
  • Check each important claim against the passage.
  • Test a question the source cannot answer.

Review the result

A useful system should make missing evidence visible. Reward an honest limitation in the evaluation instead of treating every refusal to invent an answer as a failure.
