The Fighter Controller training staff of the Royal Netherlands Air Force (RNLAF) regularly seeks to improve training to enhance the transfer of training to the operational environment and to reduce attrition of students. Recently the Fighter Controller training has been redefined using a competency perspective. The competency-based approach, as tailored for the RNLAF, ensures that the competencies identified are consistent to the Four Component Instructional Design (4C/ID) model. This approach provides a hierarchic model of competencies and skills, enabling a close relation to training design decisions, including performance assessment and grading. The paper will describe and discuss the competency analysis, the method, the results and its practical applicability.
