The article discusses the relationship between teacher professional competences and teacher work-autonomy at Sukma Bangsa Schools in Aceh, Indonesia. The study investigated differences in teacher professional competences and teacher work-autonomy in terms of gender, school location, classroom teacher/subject teacher, grade level and teaching experiences. The study indicated that most teachers of Sekolah Sukma Bangsa in Aceh were at moderate degree of teacher professional competences and most of the teachers attained a moderate degree of work-autonomy. The study showed that when the level of teacher work-autonomy increased, the level of teacher professional competences escalated; while lower level of teacher autonomy was associated with lower level of teacher professional competences. Furthermore, the study revealed that a degree to which teachers perceived work-autonomy and a degree to which teachers perceived professional competences were diverse based on gender, classroom/subject teacher, experience, level of school and location of school, even though the differences were not statistically significant.
