There is nothing wrong with schools asking parents to contribute paper or other stationary supplies for their children's classrooms, NSW Education Minister Adrian Piccoli says.
His comments follow reports that several schools across the state are asking students to bring additional paper to class.
Seven Hills North public school is among a number of schools which have introduced a paper levy in their voluntary school contribution schemes this year, according to the Daily Telegraph.
Mr Piccoli says the practice is "completely normal and completely allowable" and is an alternative to asking parents for voluntary financial contributions.
"Instead of asking for financial contributions they are asking for a particular resource," Mr Piccoli told Fairfax Radio network on Monday.
"If any parent is unable to pay, there are no consequences because it's voluntary."
His comments come after the state government slashed $1.7 billion in education spending late last year, despite criticism from teachers and parents.
Mr Piccoli denied that schools didn't have enough money to pay for their own stationary, saying the voluntary donations are "additional resources".
