The United Nations body, UNICEF, says the Papua New Guinea Government has to make education one of its main priorities.
The UNICEF head Isiye Ndombi says it is immoral to charge school fees which denies the poor an education.
He says this doesn't augur well for a country where a poverty elimination strategy is being promoted.
Dr Ndombi says the practice recycles poverty.
"I think there are ways of getting money other than charging poor parents. What I am trying to say is that you don't really help poor parents get their children to school when you are charging fees. And if you want to get those children to school then you have to help them get some money from somewhere - may be by indirect taxation or through other approaches"
