19% of college students say there was an attempt made to have sex with them when they were too drunk or incapacitated to stop what was happening.
The survey was carried out by the Higher Education Authority.
Almost 11,500 students and staff at third-level responded to the survey, with more than two-thirds being students.
Almost all female respondents said the perpatrator of sexual violence against them was a man, and two-thirds said the person who carried out the act was drunk or under the influence of drugs.
34% of students said they were forced into "non-consensual vaginal penetration"
A third of female students said they were often victims of sexualised comments - compared to just 9% of men.
Around 10% of men said they were subjected to sexual coercion - which includes feeling bribed to engage in sexual behaviour, while that rate was three times higher for women.
A quarter of students said they were unwelcome sexual rumours spread about them online
45% of student respondents said they have continued to ask someone for a date, even when the answer had been no.
