This study establishes competency indicators for digital electronics contestants in skills competitions to examine instructor importance levels as well as to observe the competency indicator performance of the contestants these instructors had trained. Using a purposive sampling method, the digital electronics skill competition “Golden Hand Award” winners and the 65 teachers selected from Taiwan who had trained the competition contestants in 2007–2015, were taken as the subjects for an importance-performance analysis (IPA). Competence was measured using the five indicators of general discipline, professional field, self-management, characteristics, and professional skills; 17 indicator connotations; and 67 indicator items. It was observed that instructors found professional field indicator facets to be the most important for teacher indicator importance levels, and that professional knowledge and abilities were the most important for the professional field. The results showed the most important of the instructors’ cognition in dimensions to be specialised field, and the most important of the instructors’ cognition in specialised fields to be professional subjects; the best performance of the contestants in dimensions to be professional skills, and the best performance of the contestants in professional skills to be the ability to measure.
