59. By way of illustration, violations of article 13 include: the introduction or failure to repeal legislation which discriminates against individuals or groups, on any of the prohibited grounds, in the field of education; the failure to take measures which address de facto educational discrimination; the use of curricula inconsistent with the educational objectives set out in article 13 (1); the failure to maintain a transparent and effective system to monitor conformity with article 13 (1); the failure to introduce, as a matter of priority, primary education which is compulsory and available free to all; the failure to take “deliberate, concrete and targeted” measures towards the progressive realization of secondary, higher and fundamental education in accordance with article 13 (2) (b)-(d); the prohibition of private educational institutions; the failure to ensure private educational institutions conform to the “minimum educational standards” required by article 13 (3) and (4); the denial of academic freedom of staff and students; the closure of educational institutions in times of political tension in non-conformity with article 4. 3. Obligations of actors other than States parties 60. Given article 22 of the Covenant, the role of the United Nations agencies, including at the country level through the United Nations Development Assistance Framework (UNDAF), is of special importance in relation to the realization of article 13. Coordinated efforts for the realization of the right to education should be maintained to improve coherence and interaction among all the actors concerned, including the various components of civil society. UNESCO, the United Nations Development Programme, UNICEF, ILO, the World Bank, the regional development banks, the International Monetary Fund and other relevant bodies within the United Nations system should enhance their cooperation for the implementation of the right to education at the national level, with due respect to their specific mandates, and building on their respective expertise. In particular, the international financial institutions, notably the World Bank and IMF, should pay greater attention to the protection of the right to education in their lending policies, credit agreements, structural adjustment programmes and measures taken in response to the debt crisis. 29 When examining the reports of States parties, the Committee will consider the effects of the assistance provided by all actors other than States parties on the ability of States to meet their obligations under article 13. The adoption of a human rights-based approach by United Nations specialized agencies, programmes and bodies will greatly facilitate implementation of the right to education. 29 See the Committee’s general comment No. 2, paragraph 9.
