The purpose of this study was to analyze efforts to increase the synergy between teachers and supervisors in improving academic supervision. This research uses qualitative research with a case study approach. The types of data in this study are primary data and secondary data. This research was conducted using a best practice approach carried out in the Mande sub-district, with the object of research including nine fostered teachers from Middle School 1 Mande, Middle School 2 Mande, Middle School 3 Mande, Middle School Plus Al-Bidayah Islamic Middle School Ibnu Umar , all of which are located in Cianjur district. Based on the results of the data and analysis, it can be concluded that to achieve the learning goals that have been determined, both teachers and supervisors must be able to work together and synergize well. Because with good synergy between teachers and supervisors, both parties can continue to upgrade their skills and professionalism, as well as make the learning process more focused and measurable in accordance with the provisions set out in the national education system.

The research is motivated by the limited capacity of Islamic religious education (PAI) instructors in the Ministry of Religion of Cianjur Regency to conduct Classroom Action Research. Therefore, the researcher attempts to enhance the skills of the teachers of the district. This study employs a qualitative research methodology with action research methods along with mentoring techniques. The data collected are using a variety of methods, such as observation techniques, interviews, and portfolios. Based on the findings and analysis, the Islamic religious education teachers’ ability in conducting action research increased. This is demonstrated by the following. 1) The percentage of PAI teachers engaged in CAR activities which was initially 55%, has improved to 88% after the last cycle. It requires that coaching and mentoring activities for Islamic Religion education teachers have a positive effect on the teacher's ability to carry out PTK.
