The Department of Education's under fire for 'not grappling' with a shortage of teachers.
There are currently 643 primary school jobs advertised on the Education posts website, with 456 jobs on offer at secondary schools across the country.
Labour's Aodhán Ó Riordáin says many children won't now be educated by trained teachers when the new term starts in just a few weeks time.
He says educators can't find housing, especially in the capital. Over 1000 primary and secondary school positions are lying unfilled nationwide today, according to educationposts.ie.
A chronic shortage of housing and high cost of living are among the reasons blamed.
Noel Daly, Principal of Portlaoise College, says schools outside cities are benefiting from a migration of teachers.
