The Africa Teacher Foundation is a non-profit organization (501-c-3), which introduces research-based philosophies and strategies to teachers in Africa. The Africa Teacher Foundation was established in 2007 to help African teachers use best educational principles and practices to improve their curricular and instructional standards. These improvements will, in turn, enhance the quality of life for children residing in the poorest slums in East Africa. Participants from slum, rural, and national schools in Kenya, Tanzania, and Uganda receive ten days of professional development and support to learn varied approaches to meet the needs of all learners across the basic skill areas of literacy, mathematics. To date, 2500 teachers from 500 schools have been trained and through these teachers more than 35,00 students have been reached.
