Some students in Wales will not graduate on time or with their final grades due to a marking boycott.
Cardiff University confirmed some would graduate with an unclassified degree while Swansea University said up to 70 would have their graduations delayed.
The University and College Union boycott is part of a pay dispute.
On Wednesday, the new student union president at Cardiff University launched a petition calling for an end to the dispute.
Meanwhile, Swansea University said a "small group" - less than 70 students out of a total of 2,500 - would be unable to graduate on time as a result of the marking and assessment delays.
A spokesperson said: "We are working diligently to ensure that award outcomes are promptly confirmed for all students. We encourage our students to reach out to their faculties should they have any queries or concerns."
In a joint statement with her fellow sabbatical officers, new students' union president at Cardiff University Angie Flores Acuña said the graduation disruption marked "another failure for students".
