In many developing countries, the government remains the main financier and the dominant provider of education. The demand for quality education continues to increase while resources remain scarce, making education inaccessible to a significant part of society.
An innovative way of financing education is via cash transfers to schools based on enrollments or by providing cash to families to purchase schooling – in other words- through vouchers. Another way is to reach education providers directly and ensure they deliver the services by fulfillment of a contract such as Charter Schools (in the USA), Academies or Free Schools in the UK or concession schools in Colombia, which are examples of this mechanism. The objective in both cases is to extend financial support from the government to providers and parents and promote access to quality education. Advocates of these systems argue that this will lead to efficiency gains, as schools – public and private – vie for students and try to improve quality while reducing expenses.
