[ASSESSMENT](https://avioverse.aero/glossary/easa/assessment) OF ASSESSOR COMPETENCE

The level of harmonisation on competence assessment is low as a result of the variety of methods. Any assessment of assessor competence should be realistic and it could take place during live traffic situations or during training.
