General Background: Quality education requires continuous teacher professional development supported by structured academic supervision. Specific Background: In practice, academic supervision in kindergartens often remains administrative and lacks reflective guidance, particularly in Aceh Tamiang Regency. Knowledge Gap: Limited studies integrate coaching techniques within academic supervision at the early childhood education level, especially in local contexts. Aims: This study examines the implementation of academic supervision through coaching techniques to improve kindergarten teacher professionalism. Results: Using a qualitative case study with interviews, observations, and document analysis, findings show supervision is conducted systematically through planning, classroom observation, reflection, and coaching-based follow-up. The approach encourages self-reflection, improvement of learning tools, adaptation of teaching strategies, and increased consistency in lesson plan implementation, classroom management, and professional responsibility. Novelty: The study provides a contextualized analysis of structured coaching integration within annual supervision cycles in kindergarten settings, highlighting its institutionalization in school quality management. Implications: Coaching-based academic supervision supports reflective and collaborative practices, strengthens teacher motivation and confidence, and contributes to improved learning quality in early childhood education.
