This study explores parental satisfaction in a private international school in Surabaya, Indonesia, focusing on how well the school meets expectations in terms of Learning Quality, Teacher Quality, and Facilities. As education becomes increasingly market-driven, parents play a vital role as primary stakeholders whose satisfaction impacts school reputation, loyalty, and student success. The objective is to identify key factors influencing satisfaction by comparing parental expectations with actual school performance using Important-Performance Analysis (IPA) and regression analysis. A quantitative descriptive approach was used, collecting data from 133 parents across various grade levels. Findings revealed that Learning Quality and Facilities Quality significantly affect parental satisfaction, while Teacher Quality showed no statistical significance, likely due to uniformly high ratings. The analysis highlights critical gaps in areas like real-world learning and academic facility quality, emphasizing the need for targeted improvements. These insights offer practical guidance for school administrators seeking to enhance educational service delivery and build stronger parent-school relationships.
