In this study, the effect of governance on SDG4 has been studied in Iran since 1990 to 2019 using the GMM method. The potential energy amount formula saved in the electric circuit capacitor (Physics) has been applied for the theoretical foundations. The foregoing results denote that there is a weak contact among government, government expenditure on education and effectiveness with inequality in education because of paying inadequate attention by the governance to remove the educational discrimination and also improving the economic, social and cultural abilities. Also, the poor relation between Gross National Income Per Capita (GNI) and Inequality in Education can be indicative of the low quality of education in the educational canters therefore those families that are of lower affordability will be liable to the educational discrimination. Accordingly, the governance here in Iran can be realized by increasing the welfare, prosperity and improving the education quality (Graders & Students) and increasing the levels of qualification (Teachers & Professors) with the aim of lasting and perpetual educations based on experience, practice and research. These can also materialize the SDG4 in Iran and then propel the sustainable development realization in Iran towards the reality through improving Iran's human development index. Also, the government can accelerate the SDG4 realization by implementing a total structure and an appropriate mechanism and also by decreasing the urbanization growth and applicable budget appropriation and through the justly distribution of educational facilities and the pulling power of teaching method.
