A/HRC/38/32/Add.1 teachers who meet the relevant teaching requirements. Accessibility means that the system must be accessible to all, without geographical, economic, social or cultural discrimination, and affirmative action must be taken to include groups that are particularly marginalized. Acceptability means that the content of education must be relevant, non-discriminatory, culturally appropriate and of good quality; the school environment must be healthy and safe and the teachers must be professionals. Adaptability means that education must evolve with the changing needs of society and help to challenge inequalities, especially gender discrimination, and it must be able to be adapted locally to suit specific contexts. A. Availability 46. With regard to funding, as previous Special Rapporteurs have pointed out, investment in education is a human rights obligation that States must fulfil. The Ivorian Government has approved a 10-year plan for the education and training sector for 2016– 2025, at an estimated cost of CFAF 5,246 billion for the period 2017–2020, with the aim of providing inclusive, quality basic education for all. An additional sum of CFAF 19.1 billion has been set aside for measures to increase the enrolment rate among girls. In 2017, a total of CFAF 908 million was allocated to the literacy programme. 47. In principle, for the right to education to be effectively implemented, public education should be free, without any costs that might act as a barrier. The Education Act provides that public school education should be free and available to all; however, some costs, such as enrolment fees, social services and the cost of textbooks and other school supplies, are not covered. These exceptions mean that low-income families are likely to come into conflict with the law, because they do not have the financial means necessary to cover the compulsory extra costs of their children’s education. Moreover, according to the information received, in rural areas particularly, communities must sometimes contribute to the remuneration of voluntary teachers through subsidies paid to the school management committee, which has led UNESCO to conclude that households cover between 30 and 37 per cent of the costs of education. Primary education 48. Universal primary education, which has been identified as Sustainable Development Goal 4 and a goal of the African Union, is also a key goal of the Ivorian Government. With the support of international bodies and local stakeholders, the Government has launched a series of initiatives relating to the renovation and construction of school infrastructure, the training and recruitment of teachers and the purchase of teaching materials and equipment. Secondary education 49. The number of secondary schools has risen slightly over the past five years. The Special Rapporteur is pleased to note that the Government allocated a budget of CFAF 333 billion to the development of secondary education in the 2016–2020 National Development Plan. This investment will be used, in particular, for the renovation, construction and equipment of school buildings and the recruitment of staff. Teacher training 50. As in many countries, the lack of qualified teachers is a challenge for the authorities; this problem concerns all levels of the education system, including higher education. It can also be noted that the geographical distribution of teaching staff at both primary and secondary level is very uneven, with a high concentration of teachers in major cities. Around 30 specialized schools help to provide training for teaching and educational support staff, under the responsibility of the relevant ministries. The Special Rapporteur recommends working hand in hand with universities to resolve the practical problems that arise when dealing with large class sizes and to promote a teaching method that focuses on the learner and on cultural values. She also recommends taking steps to increase the prestige of the teaching profession in order to motivate teachers to perform well. GE.18-06824 9
