The SACMEQ III Project commenced in 2006 and was completed during 2011. The SACMEQ III data collection was implemented in fifteen SACMEQ Ministries of Education (Botswana, Kenya, Lesotho, Mauritius, Malawi, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania (Mainland), Tanzania (Zanzibar), Uganda, Zambia, and Zimbabwe). The SACMEQ III Project followed the general research direction of the first two SACMEQ Projects by focusing on an examination of the conditions of schooling in relation to achievement levels of learners and their teachers in reading, and mathematics. The focus was expanded to cover the learners’ levels of basic knowledge about HIV and AIDS. The SACMEQ III Project involved data collections from around 61,000 learners, 8,000 teachers, and 2,800 school principals.
