The education system is well supported in financial terms by the Government, which allocates as much as 20% of the State budget to education. Most (52%) of this expenditure is directed to primary and lower secondary education. The system is also well supported by private household expenditure. Indeed, private household expenditure on education is now claimed to be approaching or exceeding public expenditure on education. Tuition fees, which are charged at all levels other than for primary education, are a significant component of private household expenditure on education and were estimated in 2006 to account for 31.8% of all private household expenditure on education.
