The Department of Education spent over 104 million euro on the salaries of teachers in private schools last year.
It covered 51 fee-paying schools across the state.
The highest amount was paid to teachers in St Andrew's College on Booterstown Avenue, at almost 4.2 million.
While Blackrock College was next, at just over 4 million.
Both of these schools had more than 1,000 students during the year.
The Social Democrats education spokesman, Gary Gannon, says it isn't appropriate for the state to fund the salaries of teachers in private schools.
Gary Gannon, Social Democrats Education Spokesman, said it is not appropriate for the State to fund the salaries of teachers in private schools.
"What I can't accept is the State continuing to allow wealthier cohorts of society to lock in their privilege, through investing in private education, that is bucked up by the State's investment of over €100 million coming from the taxpayer," he said.
Deputy Gannon said this was being used "to fund a rather small cohort of people to ensure that they get more advantages going into the Leaving Cert, and inevitably into the best places in third-level education."
In total, the salaries of teachers in seven private schools across the State came to over €3 million last year.
