CRPD/C/GC/4 participation in political and societal processes. Public affairs include forming and participating in student organizations such as student unions and States parties should promote the creation of an environment in which persons with disabilities can form, join and effectively and fully participate in such student organizations through the forms of communication and language of their choice (art. 29). 58. States parties must remove barriers and promote accessibility and availability of inclusive opportunities for persons with disabilities to participate on an equal basis with others in play, recreation and sports in the school system and in extracurricular activities, including in other educational environments (art. 30).21 Appropriate measures must be in place within the educational environment to ensure opportunities for persons with disabilities to access cultural life and to develop and utilize their creative, artistic and intellectual potential, not only for their own benefit but also for the enrichment of society. Such measures must ensure that persons with disabilities are entitled to recognition of their specific cultural and linguistic identity, including sign languages and deaf culture. V. Implementation at the national level 59. The Committee has identified a number of challenges facing States parties in the implementation of article 24. In order to implement and sustain an inclusive education system for all persons with disabilities, the measures below need to be addressed at the national level. 60. Responsibility for the education at all levels of persons with disabilities, as well as for the education of others, must rest with the education ministry. In many countries, the education of persons with disabilities is currently marginalized within ministries of social welfare or health, which has resulted in, inter alia, exclusion from mainstream legislation, policies, planning and resourcing for education, lower levels of per capita investment in the education of persons with disabilities, a lack of overarching and coherent structures to support inclusive education, a lack of integrated data collection on enrolment, retention and attainment, and a failure to develop inclusive teacher education. States parties must urgently take measures to put the education of learners with disabilities under the competence of the ministry of education. 61. States parties must ensure a comprehensive and intersectoral commitment to inclusive education throughout the government. Inclusive education cannot be realized by education ministries in isolation. All relevant ministries and commissions with responsibilities that cover substantive articles of the Convention must commit to and align their understanding of the implications of an inclusive education system in order to achieve an integrated approach and to work collaboratively towards a shared agenda. Accountability measures for all ministries involved must be put into place to uphold such commitments. Partnerships should also be forged with service providers, organizations representing persons with disabilities, the media, civil society organizations, local authorities, student associations and federations, universities and teacher education colleges. 62. States parties, at every level, must implement or introduce legislation based on the human rights model of disability that fully complies with article 24. The Committee recalls that article 4 (5) requires federal States to ensure that article 24 is implemented, without limitations or exceptions, in all parts of the State party. 63. A comprehensive and coordinated legislative and policy framework for inclusive education must be introduced, together with a clear and adequate time frame for 21 16 Ibid., general comment No. 17 (2013) on the right of the child to rest, leisure, play, recreational activities, cultural life and the arts.
