E/C.12/NDL/CO/4-5 about the practice of the use of isolation as a form of punishment when prisoners cause trouble, without due regard being given to the health implications involved (art. 12). The Committee recommends that the State party address the problem of medical treatment of prisoners with mental health problems and take the necessary measures to increase the number of trained mental health personnel in penal institutions or to guarantee appropriate treatment in mental health institutions. The Committee urges the State party not to use isolation as a form of punishment when prisoners with mental health problems cause trouble. 31. The Committee is concerned that, while education is compulsory for all children, regardless of their legal status, undocumented children opting to enrol in vocational education programmes are not yet able to complete their apprenticeships because of work permit requirements in the Netherlands (arts. 13 and 2, para. 2). The Committee recommends that the State party take appropriate remedial measures to ensure that undocumented children who enrol in vocational education programmes in the Netherlands are able to complete their apprenticeships. 32. The Committee is concerned that the national school curricula of the State party do not provide for adequate human rights education (art. 13). The Committee calls on the State party to ensure that human rights education is provided in schools at all levels and universities, and that it covers the economic, social and cultural rights. 33. The Committee encourages the State party to take advantage of the institutionbuilding process taking place in Curaçao and St. Maarten to ensure that their enactments and policies give effect to the economic, social and cultural rights enshrined in the Covenant. In this regard, the Committee draws the attention of the State party to its general comment No. 3 (1990) on the nature of States parties’ obligations. 34. The Committee welcomes the progressive reforms brought to the social security system in the four constituent countries of the State party and encourages the State party to take account of the Committee’s general comment No. 19 (1997) on the right to social security in future initiatives to be taken to improve the social security system (art. 9). 35. While recognizing the measures taken in the Netherlands to combat human trafficking, the Committee urges the State party to continue and intensify its efforts to combat trafficking as long as the Netherlands remains a destination or transit country for trafficking. The Committee also recommends that the State party provide in its next periodic report detailed information about the problem of human trafficking in the islands of the former Netherlands Antilles and the impact of measures taken (art. 10). 36. The Committee recommends that the State party adopt a national plan of action to combat the rise in homelessness in the Netherlands, and to consider its causes and prescribe ways and means of preventing homelessness and rehabilitating the homeless (art. 11). 37. The Committee recommends that the State party intensify its efforts to reduce the waiting time of six weeks in the Netherlands for children and adolescents needing mental health care (art. 12). 38. The Committee recommends the State party to provide, in its sixth periodic report, updated statistical data on the enjoyment of each Covenant right, 9
