Abbey College on Dame Street, which specialises in English language training, has ceased trading.
In a statement on its website the college said it is seeking alternative arrangements for students who have not completed their tuition after the college closed on Friday but that this could take some weeks.
It apologised to students and said that steps were being taken to appoint a liquidator and wind up the company.
It said details will be posted on its website, www.abbeycollege.ie, as they become available.
For students whose tuition period has finished, the statement says their details have been sent to the Garda National Immigration Bureau.
Abbey College specialised in English language teaching but also provided other foundation and diploma courses for a number of awarding bodies in Ireland and the UK.
