The shape of Figure 2 indicates at what level the program was effective. The effect is increasing until the sixth year of education, decreasing until the twelfth, and slightly increasing thereafter. A maximum of about 6 percent of the sample living in high program regions were induced to complete at least primary school. This also shows some impact of the program on the probability of completing lower secondary school(1.5 percent of the sample is estimated to have been induced by the program to complete the 7th,8th,and 9th grades or more). There is a negative difference in differences at the senior high-school level.
