The purpose of this study was to find out the digital competencies of vocational high school students and to derive implications for increasing the digital competencies of vocational high school students by identifying what competencies currently need to be improved most urgently. The results are as follows. First, the digital competency of vocational high school students was defined as the competency, including knowledge, skills, attitudes, and thinking skills that vocational high school students must have in common to perform their duties using various digital technologies after entering the labor market after graduation. Second, 5 major areas of vocational high school students' digital competencies were derived: 'understanding and responding to changes according to digital transformation', 'digital data collection and management', 'digital-based communication and collaboration’, ‘digital content development and utilization’, and 'digital-based problem solving' and minor 11 areas were derived. Third, ‘communication through digital technology’ and ‘digital data search and collection’ were identified as areas with high level of performance and importance, but ‘digital content development’ was identified as areas with low level of performance and importance. Fourth, competencies with high demand for improvement include ‘digital data search and collection’, ‘communication through digital technology’, ‘sharing and collaboration through digital technology’, and ‘digital content utilization’. In the suggestion, it was suggested that long-term research should be conducted to find ways to increase digital competencies of vocational high school students, and specific policy should be established that focus on improving students' foundational common competency.
