The Ministry of Education recruited 20,000 new teachers in 2005 and continued to implement teacher training. Teachers tend to be underpaid, inadequately trained and overworked (sometimes teaching two or three shifts a day). Some teachers may reportedly demand payment or bribes directly from their pupils. Other factors, such as the presence of landmines, lack of resources and identity papers, and poor health prevent children from regularly attending school. Although budgetary allocations for education were increased in 2004, the education system in Angola continues to be extremely under-funded.
