The impact of the professional learning community on teachers' professional development has been studied in different contexts. However, the number of studies on the voices of secondary teachers in Malaysian Independent Chinese Secondary Schools [MICSS) needs to be more detailed. This study aimed to investigate how teachers in MICSS view the impact of the Professional Learning Community (PLC) on their professional development. Data for this study was collected using semi-structured interviews with eight MICSS teachers selected from two different-scale MICSSs. The patterns were analyzed by repetitive data reading, data coding, and theme creation. The findings show that with the help of PLC, MICSS teachers may improve their professional development more effectively, particularly in enhancing their knowledge of their subject, students, effective teaching methodology, and sense of occupational belonging. Moreover, collective learning and classroom observation procedures are the most effective among all the PLC activities in the MICSS context. The findings have practical implications for teachers and trainers to improve teachers' profession by establishing professional learning groups.
