Since the start of the 2011 school year, more than 15,000 teachers have been employed, 30,000 classrooms have been renovated and almost 300 new schools have been built. In 2015, the gross enrolment ratio for children aged 6-16 was close to 95%, compared to less than 75% in 2007. The government is also paying close attention to secondary and tertiary education. Around a hundred high schools ( junior and senior) and four regional universities were built and equipped to strengthen the existing schooling network. Due to the 110 billion CFA francs invested by the education department, public universities, which had been closed for two years, were able to re-open in 2012, including the AbidjanCoco dy, Ab odo-adj amé,Bouaké and Korhogo campuses and the Institut National Polytechnique Houphouët-boigny (INPHB) in Yamoussoukro. With the current population of 23 million set to double by 2050, Côte d’ivoire is facing an immense challenge.
