The research discusses the achievement of four competencies in electrical installation for vocational education students of electrical engineering: planning, preparing, installing, and testing competencies in the electrical installation fields that must be achieved by each student. The learning process is carried out with the help of project-based practice modules for each student. Validated performance assessment rubrics are used as data collection instruments to measure the level of competency achievement. The research subjects are 18 students who took part in the domestic electrical installation practice learning process. The aim of this research is to determine the level of student achievement in four competencies by using a project-based learning model. The results show that the total average of the achievement values for four competencies as a whole is 87.6, where separate scores for the competencies of planning, preparation, implementation, and testing are 84.8, 87.1, 91.3, and 87 respectively. It can be concluded that the implementation of project-based learning models is effective for students to achieve all four electrical installation competencies.
