CRC/C/DZA/CO/3-4 (b) The lack of a transportation system for pupils with disabilities and the lack of accessibility of school buildings are major obstacles to their integration into mainstream schools; (c) Mainstream school teachers are not trained to support children with disabilities and that there is lack of personnel to provide individual support to children with disability in the classrooms; (d) Children with multiple disabilities are not accepted in specialized centres and are therefore totally deprived of any educational opportunities; and (e) Programmes and support provided to children with disabilities in specialized centres are obsolete. 56. The Committee reiterates its previous recommendations (CRC/C/15/Add.269, para. 54). The Committee urges the State party to review the situation of children with disabilities in terms of their access to suitable health-care and education services and adopt as a matter of priority a comprehensive policy to develop inclusive education. In this regard, the Committee urges the State party: (a) To promote the social and human rights based approach which acknowledges that the disabling factors reside in the environmental and attitudinal barriers created by society, and that all children with disabilities are subjects of their own rights, and undertake awareness-raising campaigns aimed at the government, public and families to promote the positive image of children and adults with disabilities and their role as active participants and contributors to society; (b) To ensure that the development of inclusive education is given priority over the placement of children in specialized institutions, paying particular attention to children with mental and multiple disabilities; (c) To provide sufficient numbers of specialist teachers and professionals providing individual support into all schools and ensure that all professionals are adequately trained so that all children with disabilities can effectively enjoy their right to quality inclusive education; (d) To ensure transportation and support in classrooms, and the accessibility of educational materials, curricula, and school environments; (e) To ensure that enforceable remedies are provided to children with disabilities and their families who have been refused access to inclusive education, or who have been denied the provision of reasonable accommodation with respect to education; (f) To consider ratifying the Optional Protocol to the Convention on the Rights of Persons with Disabilities; and (g) To take guidance from the Committee 2006 general comment No. 9 on the rights of children with disabilities (CRC/C/GC/9). Health and health services 57. The Committee expresses concern that budgetary allocations to the health sector remain greatly insufficient to address the health problems of children, especially those living in rural areas who face considerable difficulties in accessing health care due to an unequal geographic distribution of care facilities and medical practitioners. The Committee is also concerned about: (a) Maternal, neonatal and under-five mortality rates, which remain at very high levels; 13
