The results of the scale test using Cronbach's Alpha and the EFA factor analysis help us extract the components of leadership style affecting student satisfaction: (1) Ohao Smart design and landscape, (2) Ohao Smart responsiveness, (3) Ohao Smart support service quality, (4) Food quality /reliability, (5) Ohao Smart price. The scale of research concepts has reached convergent and discriminant validity through satisfying the conditions of EFA factor analysis and Pearson correlation analysis. The test results of linear regression show that all 5 components have a leadership style that positively impacts student satisfaction at a significant value of < 0.05 (95% significance level). The model test results show that the model is suitable, there is no violation of the test assumptions, and the results of testing the hypotheses are accepted. Keywords---Leadership style, student satisfaction, Ohao Smart. 1.
