CRC/C/15/Add.99 page 8 of Opportunities for Persons with Disabilities (General Assembly resolution 48/96), the Committee recommends that the State party develop early identification programmes to prevent disabilities, increase its efforts to implement alternatives to the institutionalization of children with disabilities, establish special education programmes for children with disabilities and further encourage their inclusion in society. The Committee also recommends that the State party seek technical cooperation for the training of professional staff working with and for children with disabilities. International cooperation from, inter alia, UNICEF and WHO can be sought to this effect. 27. The Committee remains concerned at the situation of education, particularly as regards overcrowding, the high drop-out rate, the lack of basic training materials, poorly maintained infrastructure and equipment, shortages of textbooks and other materials, the limited number of trained teachers and the lack of play space and recreational facilities. The Committee is also concerned that some children, particularly immigrant children and those living in poverty and among minority and indigenous communities, still do not have access to education. The Committee expresses further concern that the school curricula do not adequately address the special situation of non-English-speaking children, particularly the minority indigenous and Spanish-speaking children. The Committee recommends that all appropriate measures be taken to improve the quality of education and to provide access for all children within the State party. In this regard, it is recommended that the State party seek to strengthen its educational system through closer cooperation with UNICEF and UNESCO. The Committee also recommends that the State party seek to implement additional measures to encourage children to stay in school, particularly during the period of compulsory education. The Committee further recommends that the State party seek to ensure the right of the child to rest and leisure and to engage in play and recreational activities. The State party is further encouraged to review its educational policies and programmes with a view to ensuring that they adequately reflect the cultural and ethnic diversity of the population. 28. Child labour and economic exploitation are matters of concern, particularly the situation of immigrant children working in the banana industry. The Committee encourages the State party to introduce monitoring mechanisms to ensure the enforcement of labour laws and protect children from economic exploitation. In this regard, it is further recommended that the State party undertake a study on the situation of children engaged in hazardous work, especially those employed in the banana industry. The Committee also suggests that the State party consider ratifying ILO Convention (No. 138) concerning Minimum Age for Admission to Employment. 29. The Committee is particularly concerned at the high and increasing incidence of drug and substance abuse among youth; the lack of legal provisions in relation to narcotic drugs and psychotropic substances; and the limited social and medical programmes and services available in this regard. In the light of article 33 of the Convention, the Committee recommends that the State party take all appropriate measures, including legislative, administrative, social and educational measures, to protect children from the illicit use of narcotic drugs and psychotropic substances, and to prevent the use of children in the illicit production and trafficking of such substances.
