Over 100 teachers and students have gathered outside the Dáil in protest at cuts to teacher numbers on further education courses.
The demonstration was organised by the Dublin City branch of the Teachers Union of Ireland.
Protesters say the cuts, which were introduced in the last Budget, will mean that many further education courses will be scrapped in September 2013.
They say the plan will result in the loss of 8,000 further education places nationally, and the dismantling of a key access route to university.
Speaking on RTÉ's Morning Ireland, Deputy Principal of Ballyfermot College Kevin Devine said the loss of specialist staff will result in fewer courses being offered at such colleges.
Mr Devine said it will mean "some courses will have to be cancelled and, therefore, it will mean fewer places for students, with a knock-on effect for the following year".
