This study analyzes the effects of digital leadership by school principals, teacher competence, and the availability of facilities and infrastructure on the educational quality of state senior high schools in Pelalawan Regency. A quantitative ex post facto design was employed, with a population of 214 teachers and a sample of 138 selected via proportional random sampling. Data were collected using questionnaires validated for content and reliability (Cronbach’s α = 0.961–0.983) and analyzed through multiple linear regression. Descriptive results revealed mean scores of 24.62 (38.49 %) for educational quality, 24.63 (38.50 %) for digital leadership, 22.48 (35.14 %) for teacher competence, and 26.29 (41.09 %) for facilities and infrastructure. Partial tests indicated significant effects of digital leadership (β = 0.150; t = 2.373; p = 0.019), teacher competence (β = 0.294; t = 4.097; p < 0.001), and facilities and infrastructure (β = 0.520; t = 9.162; p < 0.001) on educational quality. The simultaneous test yielded F = 160.838 (p < 0.001) and R² = 0.783, indicating that these three variables collectively explain 78.3 % of the variance in educational quality. Further research should explore external factors such as student characteristics and parental support to enhance the predictive model and broaden the generalizability of these results across diverse educational contexts.
