E/C.12/IRN/CO /2 and Azeris. It also recommends that the State party take steps to improve the quality of instruction in and physical infrastructure of schools in rural areas, and to increase the number of female teachers in rural areas. 28. The Committee is concerned that many children, in particular those in rural areas, are not registered at birth, creating an obstacle to school enrolment. It is concerned that refugee children have reduced access to primary education due to the lack of personal documents and the non-registration of their parents with the authorities, as well as the imposition of enrolment fees. The Committee is also concerned about the lack of access to education of children with disabilities and children of nomadic communities (arts. 13 and 14). The Committee recommends that the State party intensify its efforts to ensure that all children receive birth certificates and that the lack of such a document is not an impediment for school enrolment of a child. It recommends that the State party take measures to ensure that refugee children have access to education, regardless of whether their parents have registered with the authorities, and that primary education, including enrolment thereto, is offered free of charge. The Committee also recommends that the State party intensify its measures to guarantee an inclusive education for children with disabilities, including through the Organization for Special Children and the Seven-Point Guideline for Universal and Consolidated Education for Children and Students with Special Needs, and to ensure that all children of nomadic communities have access to primary education, including through the establishment of mobile schools. 29. The Committee is concerned that ethnic minorities face severe res trictions in practice with regard to education in their mother tongue, including Azeri, Kurdish, and Arabic, despite policies protecting the use of non-Persian languages (arts. 13 and 14). The Committee recommends that the State party take steps to ensure that ethnic minorities have the opportunity to receive education in their mother tongue, in addition to Farsi. 30. The Committee is concerned that ethnic minorities, including Kurds, Arabs, Azeris and Baluch, do not fully enjoy their right to take part in cultural life, including as a consequence of closures of publications and newspapers in minority languages (art. 15). The Committee recommends that the State party take steps to ensure the full and unrestricted enjoyment by ethnic minorities, including Kurds, Arabs, Azeris and Baluch, to their right to take part in cultural life, including through the protection of publications and newspapers in minority languages from imposed closure. The Committee also recommends that the State party take measures to protect cultural diversity, promote awareness of the cultural heritage of national and ethnic minorities, and ensure favourable conditions for members of those minorities to preserve, develop, express and disseminate their identity, history, culture, language, traditions and customs in line with the Committee’s general comment No. 21 (2009) on the right of everyone to take part in cultural life. 31. The Committee recommends that the State party adopt a comprehensive antidiscrimination bill in compliance with article 2, paragraph 2, of the Covenant and taking into account the Committee’s general comment No. 20 (2009) on nondiscrimination in economic, social and cultural rights. 32. The Committee encourages the State party to consider signing and ratifying the Optional Protocol to the International Covenant on Economic, Social and Cultural Rights. 33. The Committee encourages the State party to sign and ratify the Convention on the Elimination of All Forms of Discrimination against Women, the Convention 7
