How the marking is checked
WardPass marks practice writing and speaking with a two-pass AI assessor built against the published OET criteria. This page shows how we test it, what the latest test found, and what the marking cannot do. Only claims with retained evidence appear here.
LATEST CALIBRATION RESULT
HOW IT IS TESTED
- Two assessors, every time. A first pass marks your letter or role play against each published criterion, quoting your own words as evidence before committing to any band. A second, independent critic pass verifies every score and must justify any change. You see the critic's result.
- Stability before accuracy. The same letter marked five times must land within one band on every criterion. A marker that cannot repeat itself cannot be trusted, so this gate runs before anything else.
- Calibration against references. The engine is scored against a private reference set: official published sample responses, letters with deliberately planted faults, and letters blind-graded by an experienced human assessor. The release rule: at least 90% of criterion scores within one band of the reference, or the update does not ship.
- Every dispute is reviewed by a clinician. Each feedback screen has a dispute link. A human reviews within 48 hours, explains the decision, and the case joins the reference set so the same mistake is not made twice.
HONEST LIMITS
- This is practice feedback based on published OET criteria, not an official evaluation. Estimated grades are indicative, and only OET can grade your real exam.
- Speaking is marked from an automatic transcript. Intelligibility and fluency can only partially be judged from text, so those two bands are always labelled approximate.
- Reading and listening scores convert to the 0 to 500 scale approximately; the real test's conversion varies between sittings.
- Confidence is shown on every marking. When the two passes disagree, or a submission is unusual, the feedback says so instead of pretending certainty.
