CRC/C/BOL/CO/4 page 6 Data collection 19. The Committee notes efforts made to further improve data collection mechanisms as demonstrated by recent surveys on children in school. Nevertheless, the Committee is concerned at the lack of a comprehensive system of data collection and analysis and at inadequate data on specific groups of children, particularly indigenous children, children with disabilities, children out of school, working children, children in emergency situations and other children in need of special protection. 20. The Committee recommends that the State party strengthen its efforts to develop a comprehensive system of data collection on the implementation of the Convention. The data should respect the age definition of childhood set at below 18 years and be disaggregated by sex, age, ethnicity and other relevant characteristics of children and their life situations. Dissemination, training and awareness-raising 21. The Committee is concerned at the lack of a national strategy to promote the rights of the child, and reiterates its concern about the low level of awareness of the Convention among professionals working with and for children, including the role of the media, and among the general public, especially among children themselves. 22. The Committee recommends the reinforcement of systematic training of all professional categories working for and with children, including teachers, police, lawyers, judges, health personnel, the media, social workers and personnel of childcare institutions and judicial facilities, and also the inclusion of the Convention in the school curriculum at all levels. 23. The Committee recommends that the media, both private and public, should treat children with respect, disseminate the rights of the child taking into account the cultural diversity and include in its programmes the expressions and points of view of children. The Committee further recommends that the State party encourage the media sector to establish professional codes of ethics, taking into account the rights of the child. Cooperation with civil society 24. The Committee takes note with appreciation of the importance that the State party gives to the participation of civil society. However, it is concerned at the lack of a strategy to ensure civil society participation in relation to the rights of the child, and it regrets that the State party’s report was not prepared on the basis of a wide consultation with organizations that contribute to the implementation of the Convention, as well as the children themselves. 25. The Committee recommends that the State party systematically involve communities and civil society, as well as multisectoral institutions which have been created (the National Council and the departmental and municipal Commissions) and children’s organizations in all aspects of elaboration of policies, plans, laws and regulations in the
