CRC/C/15/Add.222 page 4 14. The Committee reiterates its previous recommendation to the State party to significantly improve the effectiveness of its tax collection system and urges the State party to substantially increase the budget allocation and ensure transparency of the use of funds for the implementation of the Convention, in particular in the areas of health and education, and strengthen its efforts to eliminate corruption. Data collection 15. The Committee notes the difficulties the State party encounters in introducing a comprehensive system of data collection, as recommended by the Committee in its previous concluding observations. However, the Committee maintains that such data are crucial for the monitoring and evaluation of progress achieved and the impact assessment of policies with respect to children. 16. The Committee reiterates its previous recommendations, and urges the State party to intensify its efforts to establish a central registry for data collection and introduce a comprehensive system of data collection incorporating all the areas covered by the Convention. Such a system should cover all children up to the age of 18 years, with specific emphasis on those who are particularly vulnerable. Training/dissemination of the Convention 17. The Committee welcomes the information provided in the State party’s report on awareness-raising initiatives supported by the United Nations Children’s Fund (UNICEF) and various NGOs, and notes the information included in the written replies to its list of issues relating to the integration of the Convention into the educational system. 18. The Committee encourages the State party to continue its efforts to provide adequate and systematic training and/or sensitization on children’s rights for professional groups working with and for children, in particular law enforcement officials, parliamentarians, judges, lawyers, health personnel, teachers, school administrators and others as required. 2. General principles 19. The Committee is concerned that the right to non-discrimination (article 2 of the Convention), the principle of the best interests as a primary consideration (art. 3), the right to life, survival and development of the child (art. 6) and the right of the child to express his or her views freely according to age and maturity (art. 12) are not yet fully reflected in the State party’s legislation, policies and programmes at the national and local levels.
