Despite considerable gains in education enrollment over the past 15 years, worldwide, the adjusted net enrollment rates were 91 per cent for primary education, 84 per cent for lower secondary education and 63 per cent for upper secondary education in 2014. About 263 million children and youth worldwide were out of school. In Kenya, the high school enrollment is mainly affected by the high cost of secondary education whose per-student cost is three to six times the primary per-student cost. The Kenyan Government has made efforts to mitigate the expenses of secondary school, but in the meantime, the cost of secondary school remains on average twelve to twenty times as much as the monthly income of parents in Kenya’s rural areas.
