Trainee priests in Maynooth will be supervised at meal times under new stricter rules.
The move comes after claims that seminarians were using the gay dating app Grindr, and a suggestion that a gay subculture exists at the National Seminary.
The Irish Independent reports trainees will be required to eat breakfast and evening meals in the college instead of being allowed to choose where they dine.
Senior staff will eat with them.
A review of social media use at Maynooth has also been ordered.
The Archdiocese of Dublin confirmed earlier this month that it would not be sending its trainee priests to Maynooth.
Dublin's Archbishop Diarmuid Martin has denied that his decision has any link to the recent scandal and that he had made his decision some time ago.
