Abstract. This study explored the mentoring and supervisory practices of master teachers to strengthen Professional Learning Communities within basic education. Master teachers serve as critical instructional leaders; however, the transition from administrative oversight to transformative mentoring requires a complex balance of pedagogical expertise and relational sensitivity. Through purposive sampling, nine master teachers and nine beginning teachers were selected through inclusion and exclusion criteria. Adopting Max van Manen’s interpretive phenomenological research design, this study utilized the hermeneutic analysis to explore master teachers’ perceptions of essential supervisory qualities and the evolution of their mentoring relationships. Findings reveal that effective supervision is an "emotionally charged" process, necessitating high emotional intelligence to navigate the "relational labor" of teacher induction. Analysis indicates a developmental progression in mentoring—moving from initial rapport-building to "co-constructive dialogue" that shifts the "locus of control" from the mentor to the mentee. Critical turning points in these relationships are successfully managed through adaptive communication, facilitating a transition from mentee dependency to professional autonomy. Based on these results, the study proposes the RUIZ Framework: A Learning Action Cell, which stands for Relational Resilience, Uplifting Instructional Mastery, Integrative Problem-Solving, and Zenith of Professional Autonomy. This framework is operationalized through a proposed Learning Action Cell plan aimed at enhancing teacher resilience and instructional efficacy. The study concludes that fostering culturally responsive and self-determined professional environments is vital for sustaining collaborative excellence and professional identity formation in schools.
