vocational institutions. 61 percent of Canadians aged 25 to 34 attained some form of tertiary education which is also one of the highest among OECD countries, ranking second behind South Korea. 31 percent of Canadians aged 25 to 64 have earned a bachelor's degree or higher, which is the same as the OECD average of 31 percent. Assessment agencies The Canadian Education Statistics Council (CESC) works in collaboration with provincial and territorial departments that are responsible for education and training, on the Pan-Canadian Education Indicators Program (PCEIP). The CESC includes both the Council of Ministers of Education, Canada (CMEC) and Statistics Canada. The CESC submits an annual report, Education Indicators in Canada: An International Perspective, "supports the comparison of educational systems in Canada's provinces and territories with member [OECD] countries". The Organisation for Economic Co-operation and Development (OECD) coordinates the Programme for International Student Assessment (PISA) that is intended to evaluate educational systems—OECD members and non-OECD members—by measuring 15-year-old school pupils' scholastic performance on mathematics, science, and reading. Canada-wide The federal government's responsibilities in education are limited to the Canadian Military Colleges, and funding the education of indigenous peoples; all other matters of education in Canada fall under provincial responsibility. As such, there is a lot of variation in the management of education from province to province. In 2016, 8.5% of men and 5.4% of women aged 25 to 34 had less than a secondary school diploma (340,000 young Canadians). In many places, publicly funded secondary school courses are offered to the adult population. The ratio of secondary school graduates versus non diploma-holders is changing rapidly, partly due to changes in the labour market that require people to have a secondary school diploma and, in many cases, a university degree. Nonetheless, in 2010, 51% of Canadians had completed a tertiary education, the highest rate in the world. The majority of schools, 67%, are co-educational. Canada spends about 5.4% of its GDP on education. The country invests heavily in tertiary education (more than US$20,000 per student). Recent reports suggest that from 2006 the tuition fees of Canadian universities have increased by 40 percent. Since the adoption of section 23 of the Constitution Act, 1982, education in both English and French has been available in most places across Canada (if the population of children speaking the minority language justifies it). French Second Language education/French Immersion is available to anglophone students across Canada.
