According to UNDP, UNESCO, and GTCI reports, the quality of Indonesian education was still low, so that a joint effort (government, educational institutions and community) is required to improve the quality of education, such as participating in a program educational certificate. This research was conducted to recognize and understand the competency indicators of pedagogy, personality, social, and professional relating to certified teachers. Moreover, this research employed a qualitative method using a triangulation analysis method. The objects of the research are private vocational schools in South Tangerang City with A-grade accreditation by involving certified teachers as the respondents with the criteria of characteristics, educational background, status, experience, and readiness. The data were collected using verbal, written and structured interviews. The result revealed that teachers certified by regulations could not be considered as professional or competence teachers, which were indicated by the lack of knowledge of the certification regulations, innovation, linearity, contextual and character personality. The findings revealed the importance of supervision and evaluation, socialization and mentoring, education and training, and reciprocity.
