This study aims to examine the influence of service quality on student satisfaction and to determine the extent of its contribution to the satisfaction of Grade XI students at SMK TI Muhammadiyah Cikampek. The method used is a quantitative approach to measure the relationship between the two variables. Data were obtained through a questionnaire distributed to Grade XI students, with a total population of 747 students and a sample of 75 students, determined using Arikunto’s sample size formula. The research instrument consisted of 18 items for variable X (service quality) and 19 items for variable Y (student satisfaction). The results of the simple linear regression analysis show that the regression coefficient is 0.525. Since the coefficient is positive, it indicates a positive influence. The t-test result shows that the t-value (13.289) is greater than the t-table value (±2.000) with a significance level of 0.000, thus H₀ is rejected, indicating a significant influence of school administrative service quality on student satisfaction. The coefficient of determination (R²) is 70.8%, meaning that the quality of school administrative services contributes 70.8% to student satisfaction, while the remaining 29.2% is influenced by other factors.
