Figures from the Irish Primary Principals Network show that more than 11 students are homeless at one Cork primary school.
Twenty-three percent of schools have at least one homeless pupil while 16% have at least one student in direct provision.
The IPPN, which is based in Cork, surveyed 128 Cork schools and found that there are at least 99 students who are homeless or in direct provision.
The number of homeless students in Cork primary schools highlights the extent of the current housing and rental crisis, according to regional manager of Focus Ireland, Ger Spillane.
Mr Spillane described the figures as stark and said with the rising rental market, the situation is only going to get worse.
“There’s a huge difference between what a family is entitled to from the Home Assistance Payment versus what the market rent is. We’re seeing a new type of homeless, the working poor, people who are gainfully employed but the rental market is out of their reach because there are so few properties to rent,” he added.
