          The assessment are composed of paper exams , interviews, and practical demonstrations, which the paper exam is the main testing. The selection of interviews and practical demonstrations are depending on the assessors’ judgment. Competition should be assessed in the workplace or work environment simulated using tools and equipment specified in the maintenance documentation. It is also expected that the applicable general-purpose tools and test equipment found in most routine situations would be used where appropriate.




          The application of the test procedures should clearly indicate the knowledge of system operation, the relationship of the individual components and linkages with other systems (if applicable) within the limits of the aircraft / guidance system troubleshooting before taking any action. The work plan should take into account the applicable safety requirements and quality in accordance with industry and regulatory standards.The following conditions of assessment represent the requirements of the Regulators  and maintenance stakeholders and must be rigorously observed.




          • A person can not be assessed as competent until they can demonstrate to the satisfaction of the assessor workplace relevant elements and performance criteria of competence unit is carried out under the supervision of routine in a system and at least one important system component / line replaceable unit (LRU) for each of the following groups:
