A/CONF.189/PC.2/22 page 37 129. Furthermore, States should be encouraged to ratify the human rights treaties, including those relating to discrimination in education, without reservations and to speed up the entry into force of instruments such as the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families, of 18 December 1990.136 3. Follow-up and monitoring of States’ obligations 130. Our study has shown that some treaty bodies, despite their competence in this area, do not have the resources, or sufficient resources, to ensure effective compliance by States with the principles of non-discrimination and tolerance, particularly as regards the content of education. In this respect, it is important that the various treaty bodies should include this issue in the guidelines for the reports that States parties must submit. Moreover, particular attention should be paid to the content of education in the work of the Human Rights Committee, and especially of the Committee on Economic, Social and Cultural Rights, as that content has unrivalled potential for giving specific substance to efforts to combat discrimination and intolerance. 131. In general, United Nations treaty bodies should attach greater importance to the consideration of racial discrimination and religious intolerance and their effects, including in relation to the education of the children of minorities and migrant workers.137 Education is within the remit of several United Nations human rights bodies and specialized agencies. In order to avoid duplication or overlapping, there should be more cooperation and a greater exchange of information between these bodies and the relevant specialized agencies in areas of common interest. The cooperation between the Committee on the Elimination of Racial Discrimination and UNESCO deserves to be highlighted in this connection.138 Other committees are particularly concerned: for example, with regard to the implementation of article 13 of the International Covenant on Economic, Social and Cultural Rights, the Committee on Economic, Social and Cultural Rights can play an important role in coordinating and centralizing data on racial discrimination and religious intolerance. 132. It is also important to strengthen the monitoring mechanisms by adopting new instruments, such as an optional protocol to the International Covenant on Economic, Social and Cultural Rights, enabling the Committee concerned following efficient procedures, to consider complaints of violations of the right to equal access to education or regarding any education not based on non-discrimination and tolerance. Everyone recognizes that education is a fundamental human right and that without it other rights cannot be fully realized. It seems quite logical, therefore, to draw all the legal implications of this in ensuring the availability of appropriate remedies and effective protection for this right, as in the case of other human rights with more sophisticated monitoring mechanisms.139 The same observation can be made about other categories of persons and other treaties with obviously weak rights-monitoring mechanisms.140 133. The special rapporteurs on contemporary forms of racism, the human rights of migrants, religious intolerance and the right to education should, within the terms of their respective mandates, combine their efforts and coordinate their activities with a view to systematically addressing racial discrimination and religious intolerance in education. 134. Finally, all these treaty and non-treaty bodies, and States too for that matter, should pay particular attention to aggravated discrimination in education, that is, discrimination against
