If you're looking for the 1986 comedy of the same name, go here.
In Real Life, adults furthering their education by returning to school is a fairly common occurrence — and one that can happen for any number of reasons, even out of a genuine love of learning.
However, in the realm of movies and TV, this situation is looked upon as purely humorous. Plots in which the main adult character — and it usually is the lead; only occasionally will you see a more minor character as the focus of this sort of story — has to return to school are pretty much exclusive to the comedy genre.
Your average John Q. Dropout's reason for completing his education is nearly always related to his career, sometimes to obtain a new job requiring a higher degree of education and other times because his current job demands it. Stupidity and incompetence will often be lampshaded. The character will often be thrown amongst people outside their age group or at least act in that way. In situations involving a character being de-aged, this is a result of Compulsory School Age.
When actual school children have to repeat a grade, see Held Back in School.

Enforced with the fact that the uniform they wear as trainees has all the appearance of an institute uniform, which she has to wear too.

- In Monsters University, Don has joined Oozma Kappa after he was downsized from his sales department. Averted in that none of his humour is about his age, rather than that he's still sticking with his well-polished sales persona and patter in a fraternity environment.

- Done in an episode of Friends where Phoebe wants to do a literature course but has it ruined by Rachel who doesn't take it seriously.

- In another episode, Florida (who dropped out in the 11th grade) employs this trope because she wanted to set an example for the children as well as have an accomplishment outside of being a wife and mother. James (who dropped out in the 6th grade) forbids her from going to school because he was insecure about having a wife who was more educated than him.

- An arc in The Big Bang Theory has Penny enrolled at a history class at the local community college. If Leonard's assessment of how bad her paper was is to be believed, there's a reason she dropped out of college in the first place. She also made her female friends write a paper for her.
- In the "Kotter Makes Good" episode of Welcome Back, Kotter, teacher Gabe Kotter (Gabriel Kaplan) starts studying for his high school's senior-year exams when the principal can find no record of his scores.

- There is an earlier episode where he has to take a night course run by his old high-school principal because he never finished remedial science. His final exam gives us a classic:
