The latest increase means that the price of a paid for school dinner in a primary school or special school will have risen from £2.60 to £3.40 since the start of 2026
A headteacher said she believes "families are going to struggle" as the price of school dinners is to go up for the second time in a year.
The price of meals for pre-school, primary and special school pupils will go up by 30p, for post-primary pupils will they will rise by 15%. It follows an increase of just under 20% introduced by the Education Authority (EA) in January 2026.
Áine Leslie, principal of Malone Integrated College in Belfast, said this will put further pressure on families who are already worried about the cost of living crisis.
But the EA said that the amount parents would have to pay was still well below the average cost of producing a school meal, estimated at over £5.20.
The latest increase means that the price of a paid for school dinner in a primary school or special school, for instance, will have risen from £2.60 to £3.40 since the start of 2026.
Pupils eligible for free school meals will not be affected.
The rise in school dinner prices is not the only measure introduced by the EA in response to what they describe as "an exceptionally challenging financial position".
There will also be a change to some menus in schools, replacing baked desserts with cheaper alternatives.
Principal of Malone Integrated College, Áine Leslie, said she believes "families are going to struggle"
At Malone Integrated College about 55% of pupils have free school meal entitlement and there are also a lot of parents who are on lower incomes.
When the prices of school meals increased earlier this year, Leslie said she remembers "sitting with the head of the cafeteria and heartbreakingly decide how much to put up each item".
"I think the cumulative effect of this will be immense, particularly families who have multiple children, both at a primary school and a post-primary school, and trying to make ends meet, it's going to become incredibly difficult," Leslie told BBC News NI.
"I can't imagine what it would be like for families trying to budget that moving forward, as well as planning for Christmas.
"I firmly believe families are going to struggle at Malone.
"I do believe that there will be some families and some young people who will be worried about the stigma attached to this, and won't voice their concerns and won't ask for help. And as an integrated school, that's really sad for us.
She added: "I think it's going to be quite cutthroat for families.
"Already, we have some of our children, particularly in junior school talking about Christmas and how they've had discussions with their families that things are going to be much more scaled down this Christmas, just with the general cost of living crisis.
"And then this is only going to amplify the situation even more for young people."
Leslie added that not having a healthy, balanced diet or going without food will be a "barrier to learning".
Christos Gaitatzis is the principal of Omagh High
Christos Gaitatzis is the principal of Omagh High and described the increase of 15% on a school meal as "excessive".
"What is the price index at the moment – is it 3,4, 5%? I would imagine that would be the reasonable increase that you would put on anything, so they are going three times the value - to me it is unreasonable," he told BBC News NI
Close to 30% of pupils at his school are on free school meals.
"You would expect that the cost for a child every week, when a price of a meal is close to £5, we are talking about £20 a week, £100 a month – that's a significant cost for lunch," Gaitatzis said.
"So other measures have to be taken by the families in order to make savings, for example pack lunches – then would that diet be balanced?
"We're talking about a society where the importance of nutrition provided by schools has significant impact on your mental and physical health, so you effectively deter these families and children having these nutritious meals by putting the price up.
"Clearly this will have an overall future impact on the health of the kids."
'Flabbergasted'
The commissioner for children, Chris Quinn, says children should not have to pay the price for the financial crisis in education
Northern Ireland's commissioner for children and young people said he was ''flabbergasted" at the change.
Chris Quinn said what makes the move "particularly difficult to accept is that it comes shortly after schools were directed towards energy-saving guidance advising people who were cold to wear more clothes rather than turn up the thermostat".
"I strongly advised the Education Authority to remove that guidance and made clear that responsibility for financial pressures in education should not be transferred to children and families."
The commissioner added: "Children did not create the financial crisis in education and they should not be expected to pay the price for it.
"School meals are not a luxury. For many children they are an essential part of the school day, and these increases will hit hardest those families already struggling with the cost of living."
What other costs are increasing?
Payments to schools for school milk are at risk.
The EA currently pays milk subsidies to around 500 schools.
The Authority is to seek funding from the Department of Agriculture, Environment and Rural Affairs (Daera).
The EA are also planning to offer more parents payments to transport their children to school rather than paying for a taxi to do it.
At the minute, some parents receive parental payments if their children is eligible for free school transport but no private providers, like taxis, are available.
Charges for EA music lessons for pupils are also set to rise again, and some schemes run in schools will no longer be funded.
The Authority, however, has not specified what is at risk.
'These were difficult decisions'
In a statement, the EA said that they "were being asked to deliver important services to children and young people with insufficient funding".
They said that they hoped to save £20m by introducing the measures on top of £30m saved this year.
They also said costs, such as providing energy for schools, continued to rise.
"These were difficult decisions which sought to balance our commitment to children and young people alongside the requirement to live within the funding allocated for the year," the EA said.
"We are also mindful of the pressures across all public services in NI and of the fact that any overspend this year may impact on next year's finances."
The Northern Ireland Executive has yet to agree a budget amid a dispute with the secretary of state about how Northern Ireland is funded.
