The purpose of this study was to analyze the role of the principal in improving the quality of education at the Laboratory Elementary School of Unimuda Sorong. The methodology used was qualitative with a phenomenological approach. The study found that the role of the principal in improving the quality of education at the Laboratory Elementary School of Unimuda Sorong consisted of three stages: input, processing, and output. The input stage includes 1) Free of costs: providing free education for Papuan children and 2) Mapping: prioritizing Papuan children and transmigrants’ communities around the "Warmon Kokoda" village. The processing stage includes enlarging the classrooms, providing laboratories, creating a comfortable library for elementary school-aged children, evaluating al-Qur'an teachers, and daily controlling the Standard Operating Procedures (SOPs). Finally, at the output stage, all of the students of the past few years graduated with stable and static grades. The leadership style carried out by the principal was democratic in all respects by taking a social-persuasive approach when problems occur between teachers and parents and the surrounding community.
