Most of the witnesses I know that have graduated high school in the congregation, have had a graduation party organized for them by the congregation.
However, I have yet to see anyone who graduated college get the same treatment.
Recently, we had two college students graduate in June. One elder who was asked to attend their graduation party refused the invite.
While acknowledging that the students had worked hard, and deserved the success, he cited that he couldn't in good conscience attend the party because he was giving a talk about going to college and it wouldn't look right.
One elder in our hall actually said to me, that he refuses to give talks about the dangers of college/university because he doesn't agree with the Society's stand on education. Both him and his wife were college graduates, and his son has started university this month.
There are a lot of conflicting views from the friends about whether or not to send their kids, even though they know the Society's stance on higher education.
