The study population was all teachers in the two schools, each of which was taken 35 teachers as a sample. Data collection was carried out by observation and questionnaires. Data were tested using validity, reliability, linearity, multicollinearity, and heteroscedasticity tests. Data analysis was then performed using multiple regression analysis, t-test, F test, and determination coefficient. The results show that; first, the school principal leadership, teacher performance, and internal quality assurance systems have a significant effect on improving the education quality of SMK Muhammadiyah 1 Bambanglipuro, where the contribution given is 23.40% and the regression equation obtained is Ŷ = 3,138 + 0,106X1 + 0,109X2 + 0,086X3, while the principal’s leadership, teacher performance, and internal quality assurance system together have a significant effect on improving the education quality at SMK N 1 Pandak, where the contribution is 26.50% and the regression equation obtained is Ŷ = 3,378 + 0,150X1 + 0,162X2 + 0,049X3.
