The National Education Act of 1978, as amended in 1995, governs schools in Tanzania. It establishes different categories of schools - government schools managed by the Ministry or local authorities, grant-aided community schools owned by non-government organizations but receiving government grants, and non-government schools wholly managed by non-governmental organizations. The Act also defines key terms like local government authority, manager, owner, and types of schools. It requires all schools to register with the Commissioner of Education and obtain written approval to establish a new school in accordance with the national education policy.
