Ulster University (UU) has said all students due to graduate this summer will receive their full degree results and classifications.
A spokesperson said "robust processes" were used to ensure students could receive their qualifications.
However the university's branch of the University and College Union (UCU) has raised concerns.
It said some degrees were being awarded "based on incomplete marks and non-expert marking."
Graduations at some other UK universities have been affected by a marking boycott by members of the UCU.
That is part of a long-running UK-wide dispute between the UCU and the Universities and Colleges Employers' Association (UCEA) over pay and workload.
About 750 students at Queen's University Belfast (QUB), for example, are due to graduate over the next week without having their degree results finally confirmed.
