Delivery operations

High-stakes assessment delivery

QFlowLearn supports synchronized starts, deadline submissions, connection failures, content corrections, and result reviews.

Read the runtime contract Architecture summary
  • Synchronized starts Every learner gets the same published package version.
  • Deadline submissions Durable receipts and queues process concurrent submit requests.
  • Connection drops The browser journal keeps work until reconnection.
  • Stale or duplicate tabs One attempt authority rejects a state change from an old session.
  • Instructor edits after release A correction creates a new version and does not change live work.
  • Bad questions or answer keys Rescoring preserves original responses and records the correction.
  • Late submits and reconnects Policy-aware reconciliation records what happened and when.
  • Result challenges The attempt event trail supports review, audit, and rescoring.
