ABSTRACT
Competence is the foundation of a teacher in carrying out learning. The expertise of a teacher needs to be developed out on an ongoing basis. Competency testing is one of the stages in developing teacher skills. This study used a literature study approach. The data are presented using tables, figures, and descriptive analysis. The first analysis found that mastery of the competency of the teacher was in “good” criteria at 71.45%. The second analysis found that in the implementation of the teacher competency test the average score was 86% with “very good” category. It can be concluded that overall mastery of competence and teacher competency testing played an important role in teacher performance in vocational secondary schools in improving the quality and learning process.
