This seems to confirm the goal being linked to the graduation buff, rather than actually finishing university as the goal would suggest.
Were either of the sims in your active household when they didn't attend graduation, or were you playing a different family?
PS remember to click on the "Vote" arrow at the top of the thread, so EA flags that this is currently a problem for players.
So once I read on this thread that it was happening if Sims didnt attend gradauation, I reverted my save, as only a couple of Sims days passed since the graduation prompt. I then went ahead and had my Sim attend graduation and sure enough, the bucket list item marked off after it was completed. In both instances my Sims were in active households and I manually declined the graduation attendance prompts.
