Assessing a Candidate Who Freezes on the Radio
A training organisation is running an AROC assessment for a candidate, Mei, who has completed the required training. During the practical assessment she correctly reads back a clearance to line up and wait, but when the tower issues a conditional clearance - "behind the landing Cessna, line up and wait, behind" - she pauses for eight seconds, then reads back only "line up and wait" and omits the conditional element. Later, during a simulated emergency, she transmits a MAYDAY call but omits her position and the nature of the emergency, then stops transmitting entirely. The assessor is under pressure to pass her because the school has a backlog and she is otherwise a competent pilot. The assessor asks you, as the chief assessor, whether the performance meets the standard and what should happen next.
1. Evaluate Mei's performance against the competencies an AROC assessment is designed to test, and decide whether she meets the standard.

An AROC assessment tests more than the ability to key a microphone. It tests correct phraseology, accurate readback of clearances, comprehension of conditional instructions, and the ability to transmit a complete and correctly structured distress or urgency message under pressure.
Mei's conditional clearance readback is deficient: omitting the conditional element ("behind the landing Cessna") changes the meaning of the clearance and could lead to a runway incursion. A readback that drops a condition is not a correct readback, even if the words spoken are otherwise accurate.
Her MAYDAY call is also incomplete. A distress message must convey the station addressed, the identification of the aircraft, the nature of the emergency, the position and altitude, and the intentions of the pilot. Omitting position and nature of emergency undermines the purpose of the call and would delay or misdirect assistance. Stopping transmission entirely compounds the problem.
On the evidence, Mei does not meet the standard. The eight-second pause alone is not decisive, but the substantive omissions are. She should be given targeted remedial training and reassessed rather than passed to clear a backlog.
2. Explain the process steps you would direct before reassessment, and how you would document the outcome.

The process should be structured and documented:
Debrief: Provide Mei with specific, objective feedback identifying the two failures - the incomplete conditional readback and the incomplete MAYDAY - with reference to the required content of each.
Remedial training: Focus on conditional clearances and readback discipline, and on the structure of distress and urgency messages. Practice should include realistic scenarios with time pressure so that the skill generalises.
Reassessment: Schedule a reassessment that covers the failed competencies plus a sample of the others, so that the outcome is a fair measure of overall competence rather than a narrow re-test.
Documentation: Record the original assessment result as not yet competent, the specific deficiencies, the remedial plan, the reassessment date and the final outcome. Retain the records so the organisation can demonstrate that the assessment was conducted properly and that the candidate was not passed for administrative convenience.
Integrity check: Confirm that the assessor's decision was made on evidence, not on scheduling pressure. Passing a candidate who cannot read back a conditional clearance or transmit a complete distress call would create an unacceptable safety risk.
