E/C.12/ARG/CO/3 24. The Committee is concerned that despite the efforts by the State party to ensure universal access to education there are still incidences of children remaining outside of the education system, illiteracy, course repetition and school dropout, especially among disadvantaged and marginalized indigenous communities. It also notes with regret that indigenous communities do not always enjoy the right to intercultural bilingual education (art. 13). The Committee recommends that the State party effectively implement existing legislation to guarantee the right to education and to address, in particular, the problems of children remaining outside the education system, illiteracy, course repetition and school dropout. The Committee urges the State party to continue its efforts to remove disparities between different societal groups and promote the educational advancement of those disadvantaged and marginalized groups and provinces. It also recommends that the State party undertake effective steps to guarantee the access to intercultural education of indigenous peoples and to ensure that it is adapted to their specific needs. 25. The Committee regrets the insufficient information from the State party regarding the protection of the collective rights of indigenous peoples related to their traditional knowledge and cultural heritage in the State party, including ancestral lands, as an integral part of their cultural identity (art. 15). The Committee recommends that the State party provide, in its next periodic report, comprehensive information about specific and effective measures, including legislation, to acknowledge and protect the traditional knowledge and cultural heritage of indigenous peoples, including their ancestral lands, in line with the Committee’s general comments No. 17 (2005) on the right of everyone to benefit from the protection of the moral and material interests resulting from any scientific, literary or artistic production of which he is the author and No. 21 (2009) on the right of everyone to take part in cultural life. 26. The Committee encourages the State party to provide additional and more detailed information in its next periodic report with respect to the measures in place to ensure the right of everyone to benefit from scientific progress and its practical application, in line with article 15, paragraph 1 (b), of the Covenant. 27. The Committee requests the State party to disseminate the present concluding observations widely among all sectors of society, in particular among State officials, the judiciary and civil society organizations, to translate and publicize them as far as possible, and to inform the Committee on the steps taken to implement them in its next periodic report or earlier, as appropriate. It also encourages the State party to continue to engage national human rights institutions, non-governmental organizations and other members of civil society in the process of designing plans for the implementation of the present concluding observations and in discussions at the national level prior to the submission of its next periodic report. 28. The Committee requests the State party to submit its fourth periodic report, prepared in accordance with the revised reporting guidelines of the Committee, adopted in 2008 (E/C.12/2008/2), by 2 December 2016. 7
