Papua New Guinea's government has commissioned an investigation to find out how close to 400 million US dollars of funding for education has been spent over the past two years.
Chief Secretary Sir Manasupe Zurenuoc says some schools are on the verge of closure because of a lack of funds.
More than 200 million dollars was allocated last year for the education system, with a similar amount being allocated this year.
Sir Manasupe says the government wants to know why things worked well between 2011 and 2013, but now schools have no money to operate.
He told the newspaper, The National, the issue of schools not receiving money was more prevalent in Morobe and Madang provinces.
