CRPD/C/GC/4 into the education system. States parties should utilize all possible sources of support for teachers, including organizations representing persons with disabilities, learners with disabilities and local community members who can contribute significantly in the form of peer mentoring, partnering and problem-solving. Their involvement provides an additional resource in the classroom and serves to build links with local communities, breaking down barriers and rendering teachers more responsive and sensitive to strengths and requirements of students with disabilities. 73. Authorities at all levels must have the capacity, commitment and resources to implement laws, policies and programmes to support inclusive education. States parties must ensure the development and delivery of training to inform all relevant authorities of their responsibilities under the law and to increase understanding of the rights of persons with disabilities. The skills, knowledge and understanding necessary to implement inclusive education policies and practices include: understanding of the concept of the right to an inclusive education and its aims, knowledge of the relevant international and national legislation and policies, development of local inclusive education plans, collaboration and partnerships, support, guidance and supervision of local educational institutions, monitoring and evaluation. 74. Quality inclusive education requires methods of appraising and monitoring students’ progress that considers the barriers faced by students with disabilities. Traditional systems of assessment, which use standardized achievement test scores as the sole indicator of success for both students and schools, may disadvantage students with disabilities. The emphasis should be on individual progress towards broad goals. With appropriate teaching methodologies, support and accommodations, all curricula can be adapted to meet the needs of all students, including those with disabilities. Inclusive student assessment systems can be strengthened through a system of individualized supports. 75. In compliance with article 33, and to measure progress on the realization of the right to education through the establishment of an inclusive education system, States parties must develop monitoring frameworks with structural, process and outcome indicators, and specific benchmarks and targets for each indicator, consistent with Sustainable Development Goal 4.22 Persons with disabilities, through their representative organizations, should be involved in both the determination of the indicators and in the collection of data and statistics. Structural indicators should measure barriers to inclusive education and not be limited merely to collecting data disaggregated by impairment. Process indicators, such as on changes to the accessibility of physical environments, curriculum adaptations or teacher training, will make it possible to monitor the progress of the transformation. Outcome indicators such as the percentage of students with disabilities in inclusive learning environments obtaining final official certification or diplomas or the percentage of students with disabilities admitted to secondary education, must also be established. States parties should also consider measuring the quality of education through, for example, the five dimensions recommended by UNESCO: respect for rights, equity, relevance, pertinence, efficiency and efficacy. Monitoring affirmative action measures such as quotas or incentives may also be considered. 76. The Committee notes the growth in many countries of private-sector education. States parties must recognize that the right to inclusive education extends to the provision of all education, not merely that provided by public authorities. States parties must adopt measures that protect against infringements of rights by third parties, including the business sector. Regarding the right to education, such measures must address the obligation to guarantee the provision of inclusive education and involve, as necessary, legislation and 22 20 Office of the United Nations High Commissioner for Human Rights, Human Rights Indicators: a Guide to Measurement and Implementation (New York and Geneva, 2012).
