Teachers in Cambodia are earning merely US$20 to US$50 a month,[10] they resort to collecting informal school fees of $0.02 to $0.05 per day from students to supplement their salaries. This is just for the teacher in the city only and it is spreading to some of the provincial now. This further deters children from attending schools as they cannot afford to pay for the informal school fees. With an average of three children per household in Cambodia, the informal school fees will add up to a significant amount, making it almost impossible for parents to send their children to school. Though there are efforts by the Cambodia government to promise free provision of education, the collection of informal school fees is still a huge deterrence for children to attend school.
