Since the mid-nineties, an increasing number of developing countries have been abolishing school fees, especially at the basic levels, in order to improve their poor education outcomes. This paper analyzes the effects of these policies not only on the rate of primary enrollment, but the rates of completion of primary school and the average years of education. The analysis finds that the results vary in magnitude from country to country, but it shows that children who were exposed to the policy were significantly more likely to have enrolled in primary school, to have completed primary school, and to have had significantly more years of education.
