The CIA World Factbook estimates that, in 2000, the adult literacy rate was 84% for males and 64% for females, with UN figures suggesting a small fall in literacy of Iraqis aged 15–24 between 2000 and 2008, from 84.8% to 82.4%. The Coalition Provisional Authority undertook a complete reform of Iraq's education system: Baathist ideology was removed from curricula and there were substantial increases in teacher salaries and training programs, which the Hussein regime neglected in the 1990s. In 2003, an estimated 80% of Iraq's 15,000 school buildings needed rehabilitation and lacked basic sanitary facilities, and most schools lacked libraries and laboratories.
