The Sierra Leone Civil War resulted in the destruction of 1,270 primary schools, and in 2001, 67% of all school-age children were out of school. The situation has improved considerably since then with primary school enrolment doubling between 2001 and 2005 and the reconstruction of many schools since the end of the war. Students at primary schools are usually 6 to 12 years old, and in secondary schools 13 to 18. Primary education is free and compulsory in government-sponsored public schools.
