The Irish Primary Principals' Network is calling on the Government not to cut school capitation grants any further in December's Budget.
It comes after reports that one school in Cork is asking its pupils to bring their own toilet roll, soap, and hand towels with them, when they return to school this week, as it is struggling to cope with funding cuts.
The capitation grant has been cut in the last two budgets and many schools are now relying heavily on voluntary contributions from parents.
Spokesperson from the IPPN Larry Fleming also believes that the Government should allow schools claim VAT refunds on their purchases.
Mr Fleming said: "My message to Government would be to strongly desist from any further cuts in education because education is the rock on which any future recovery is going to be based.
"I would also ask the Government to look at the issue of VAT payments for schools.
"Schools have to pay VAT, yet they are not allowed to claim any VAT back even though they are considered charitable organisations, so I would be urging the Government to look at the issue of VAT refunds to schools."
