<![CDATA[Success in developing schools cannot rely solely on external factors such as budget, technology, and physical facilities. Internal factors, particularly teachers' commitment to their profession and institution, play a key role in fostering a high-quality learning environment. Teachers with strong commitment are more likely to take initiative, be responsible, and contribute sustainably to achieving educational goals, making them a fundamental pillar of overall school progress. This study aims to examine the influence of human resource management practices and perceived organizational support on teacher commitment, with employee engagement as a mediating variable. The research was conducted at Junior High Schools in Subrayon 09, Semarang City, involving a sample of 194 teachers. Data were collected using a 5-point Likert scale questionnaire distributed online via Google Forms. Data analysis was carried out using Structural Equation Modeling based on Partial Least Squares (SEM-PLS). The findings indicate that human resource management practices and perceived organizational support have a positive effect on employee engagement and teacher commitment. Furthermore, employee engagement directly influences teacher commitment and significantly mediates the effect of human resource management practices and perceived organizational support on teacher commitment. Abstrak Bahasa Indonesia Keberhasilan dalam mengembangkan sekolah tidak cukup hanya mengandalkan faktor-faktor eksternal seperti anggaran, teknologi, dan fasilitas fisik. Faktor internal, khususnya komitmen guru terhadap profesi dan institusi, memegang peranan kunci dalam menciptakan lingkungan belajar yang berkualitas. Guru yang memiliki komitmen tinggi akan lebih berinisiatif, bertanggung jawab, dan berkontribusi secara berkelanjutan dalam mencapai tujuan pendidikan, sehingga menjadi fondasi utama dalam kemajuan sekolah secara menyeluruh.
