The recognition of competency-based training has been popular in recent years. A lot of studies reveal the effectiveness of CBT in the term of improving workforce quality and addressing skills mismatch nowadays. Thus, this analytical study aimed to explore how the English teaching and learning process occurred at BLKK PPNT in the light of CBT-based training focused on five major investigations: learning objective, materials, teaching methods, media, and assessment strategies. This was a descriptive qualitative study undertaken at the 4th period of English training of BLKK PPNT in the fiscal year 2020. There were 16 students and one certified instructor that are involved in this study. The data were gained through observation, interview, and documentation. Data analysis was carried out through reducing, displaying, and verifying data by linking them to the existing theory. The result showed that the learning objective was to teach English for front-liners under the Indonesian National Competency Standard (SKKNI), the materials were the modules published by Ditjen Binalattas in 2016, the teaching methods implemented shared the same notion with the CBT model, the media utilized were multimedia (audio, visual, and audio-visual), and the assessment strategies were formal and informal assessments in the form of post and final testing. These findings feasibly can be a reflection for other vocational education/training units that take part in the development of CBT in the national education/training systems.
