Third-Party Audits of the AI Grading System: The grading system is periodically reviewed by external auditors checking for consistency and bias across score outcomes, with findings used to refine rubrics.

Trust on Redrob Skills is built into the mechanics, not just claimed in a policy page. Every score traces back to a fixed rubric applied identically to every candidate, every credential is recorded the moment it’s issued, and every result comes with a fairness summary showing exactly how it was reached.

If something ever feels off � a flagged session, a disputed score, a technical failure mid-test � a human reviewer is always reachable, and the process for reaching one is the same for every candidate, regardless of who they are or which test they’re taking.
