E/C.12/CO/FRA/CO/3 page 8 and older persons. The Committee requests the State party to include in its next periodic report statistical data, disaggregated on the grounds of age and gender, on the number of persons that have committed or attempted suicide, as well as information on progress made in implementing the various plans and strategies put in place to prevent suicide. 49. The Committee recommends that the State party adopt all appropriate measures to reduce the significant disparities in terms of school performance between French pupils and pupils belonging to racial, ethnic or national minorities in the field of education, inter alia by intensifying the provision of French-language courses for those students who lack adequate French-language proficiency and avoiding the overrepresentation of minority students in classes for children with learning difficulties. The Committee further recommends that the State party undertake further studies on the correlation between school failure and social environment, with a view to elaborating effective strategies aimed at reducing the disproportionate drop-out rates affecting minority pupils. 50. The Committee, while taking note that the recognition of minority groups or collective rights is considered by the State party to be incompatible with its Constitution, wishes to reiterate that the principles of equality before the law and prohibition of discrimination are not always adequate to ensure the equal and effective enjoyment of human rights, in particular economic, social and cultural rights, by persons belonging to minority groups. The Committee therefore recommends that the State party consider reviewing its position with regard to the recognition of minorities under the Constitution, and recognize officially the need to protect the cultural diversity of all minority groups under the jurisdiction of the State party, in accordance with the provisions of article 15. In this regard, the Committee reiterates the recommendation formulated in its previous concluding observations (E/C.12/1/Add.72, para. 25) that the State party (a) withdraw its reservation to article 27 of the International Covenant on Civil and Political Rights and to article 30 of the Convention on the Rights of the Child and (b) consider ratifying the Council of Europe Framework Convention for the Protection of National Minorities, as well as the European Charter for Regional or Minority Languages. 51. The Committee reiterates the recommendation formulated in its previous concluding observations (ibid., para. 26) that the State party increase its efforts to preserve and promote regional and minority languages and cultural heritage, inter alia by ensuring that sufficient financial and human resources be allocated to the teaching of regional and minority languages and cultures in public schools and to TV and radio broadcasting in these languages. The Committee also recommends that the State party consider reviewing its position concerning the lack of formal recognition of regional and minority languages in the Constitution of the State party. 52. The Committee encourages the State party to consider ratifying the Convention on the Rights of Persons with Disabilities and its Optional Protocol. 53. The Committee also encourages the State party to consider ratifying the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families.
