I Don't know where you get this information that Brazil has a minimal enforcement in the education conditionality, but it is very far from the truth.
In the bolsa familia program we have more than 90% of perfect enrollment information in the beginning and more than 97% in the end of the school year. Besides that, every two moths we have attendance information for each student. Now, we have very good information for more than 89% of our students, i.e, almost 16 milion of students.
