• Sommario/riassunto: Coming out of civil war, Mozambique had an enormous education deficit. In 199, five years after the peace treaty, 80 percent of the labor force reported to have no education at all, and school enrollment outside the large cities was miserable. Since then, Mozambique has come a long way in improving access to lower and upper primary through sustained investments in education infrastructure and introduction of important reforms. The primary education reform programs implemented in 2004, combined with a continuing program of school construction and teacher training, resulted in a 70% increase in
