One of the things that Action Zambia does in Lusaka is work with the community schools in the compounds (slums). In Lusaka, the school system is under enormous pressure due to high enrollment and a derth of teachers. Last year the universities in Zambia graduated 1000 teachers from their education programs; 2000 teachers died, most from HIV related illnesses. In order to give some education to the children, many churches have opened schools or support schools. AZ gives support and training to some of the teachers in these schools. Check out this article on a similar situation in the country of Mali.
Here are some pictures from one of the schools we visited in the Kabwata compound.
