Students at Blackburn College's University Centre were due to receive their results on 7 July following validation by Lancaster University.
Some of those have said the "systems issue" has put their careers on hold.
Staff at both centres are working to "ensure the data is accurate", which could take at least another two weeks.
'Nobody's fault'
Student Karen McErlean said: "We've had no satisfactory answer as to why results are late.
"I'm supposed to be starting a teacher training in September but I can't commence with that until I've got my degree confirmed."
Blackburn College said it was carrying out data testing on the IT system, introduced four to five months ago, when issues around the results emerged.
