For students, schools, and society, a school website is an essential thing. However, it is rare to analyze the quality of school websites, where prior research has focused more on analyzing e-government and university academic websites. In order to remain optimal and maintain its quality, a school website also needs to be evaluated regularly. In general, recommendations for quality improvement of the website will be determined in this report. To understand the existing system as the basis for collecting data and information, UML artifacts are used, i.e., requirement statements, use case diagrams, and class diagrams. The approaches utilized in this study, i.e., ISO/IEC 25010:2011 as a universal quality measurement standard and Importance Performance Analysis (IPA), to determine each item's priority for website improvement to improve quality. According to the analyzed data, the current website's performance score average is 3.29, with a negative gap (−0.22). Additionally, the existing website also has issues indicated by items in quadrant I, i.e., US2, US8, FS3, PE2, IQ2, IQ3, and IQ4. These items are the main priority for website improvement. Through these improvements, website performance has increased by 0.41, which means the average improved website performance is 3.70 with a positive gap (0.19). These results indicate that users are satisfied with the improved website performance.
