The education system in Mauritius consists of pre-primary, primary, secondary and tertiary sectors. The education structure consists of two to three years of pre-primary school, six years of primary schooling leading to the Primary School Achievement Certificate, five years of secondary education leading to the School Certificate, and two years of higher secondary ending with the Higher School Certificate. Secondary schools have "college" as part of their title. The government of Mauritius provides free education to its citizens from pre-primary to tertiary level. In 2013 government expenditure on education was estimated at about ₨ 13,584 million, representing 13% of total expenditure. As of January 2017, the government has introduced changes to the education system with the Nine-Year Continuous Basic Education programme, which abolished the Certificate of Primary Education (CPE).
