Education is a key to the economic development of nations. This research investigates the effects of education on economic development using cross-national statistical analyses of developing nations. It focuses on the impacts on economic growth of differences in levels of education (primary, secondary and higher). The statistical analysis showed that length of schooling has a significant impact on economic growth. Several patterns of the relationship are observed in the analysis. Generally, while the regression coefficient of higher education is greater than those of lower levels of education, the statistical significance shows the opposite.
