E/C.12/DZA/CO/4 State party address the low wage levels and conditions of work of health-care professionals and ensure an adequate provision and distribution of medicines and material in public health establishments. The Committee draws the attention of the State party to general comment No. 14 on the right to the highest attainable standard of health. The Committee also requests the State party to provide in its next periodic report information on policies and measures taken with regard to education in sexual and reproductive health. 21. The Committee is concerned that there are regional disparities in access to education and enrolment rates, that in the most populated wilayas the student-to-teacher ratio is very high – sometimes up to 40 students per class, and that the State party’s educational system is characterized by a high school dropout rate (less than 50 per cent of primary school students go on to the secondary level, and only 12 per cent of the primary school students obtain a higher educational degree) (arts. 13 and 14). The Committee recommends that the State party take urgent measures to address regional disparities in access to education and enrolment rates through the creation of new establishments and the expansion of the school transport system. It also recommends that the State party take steps to increase the number of school teachers at all levels and improve the conditions of work of educational personnel, including by ensuring wage increases. The Committee draws the attention of the State party to its general comment No. 13 on the right to education. 22. The Committee is concerned that the Amazigh language has not yet been recognized as an official language, despite its recognition in 2002 as a national language, and that the teaching of the Amazigh language is not generally available to all age levels and in all regions (art. 15). The Committee recommends that the State party recognize the Amazigh language as an official language and further strengthen its current efforts to ensure the teaching of the Amazigh language and culture in all regions and at all education levels, including by increasing the number of qualified Amazigh language teachers. The Committee draws the attention of the State party to its general comment No. 21 on the right of everyone to take part in cultural life. 23. The Committee recommends that the State party consider, based on the principles of necessity and proportionality, lifting the protracted state of emergency, in place since 1992, insofar as it has a negative effect on the enjoyment of economic, social and cultural rights in the State party (arts. 4 and 5). 24. The Committee encourages the State party to consider signing and ratifying the Optional Protocol to the Covenant. 25. The Committee requests that the State party disseminate the present concluding observations widely among all levels of society, in particular among State officials, the judiciary and civil society organizations, translate and publicize them as far as possible and inform the Committee of the steps taken to implement them in its next periodic report. It also encourages the State party to continue engaging the national human rights institution, non-governmental organizations and other members of civil society in the process of discussion at the national level prior to the submission of its next periodic report. 26. The Committee requests the State party to submit its fifth periodic report, prepared in accordance with the revised reporting guidelines of the Committee, adopted in 2008 (E/C.12/2008/2), by 30 June 2015. 6
