CRC/C/15/Add.233 page 5 20. The Committee recommends that the State party: (a) Strengthen public awareness campaigns on the Convention aimed at the general public and specifically at children; (b) Continue to carry out systematic education and training on the principles and provisions of the Convention for all professionals working with and for children, in particular teachers, judges, parliamentarians, law enforcement officials, civil servants, municipal workers, personnel working in institutions and places of detention for children, immigration officers, mass media personnel, health personnel, including psychologists, and social workers. 2.

The Committee recommends that the State party review the rules governing the contracting of marriage between children under 18, with a view to increasing the minimum age for marriage between under-age children who have had children together. This age should be the same for boys and girls. Awareness-raising campaigns and other measures should be undertaken to prevent early marriages. 3. General principles Non-discrimination 23.
