Nobody graduates from Hogwarts; they just leave

Have you ever noticed that there is almost no mention made of students actually graduating from Hogwarts in in any of the seven Harry Potter novels?

I mean, sure, some of the students we know (like Oliver Wood, Percy Weasley and Penelope Clearwater) clearly complete their studies and move on into the post-Hogwarts lives, and many adults in the books recall their days at Hogwarts fondly, but we never actually see, or even hear of, a graduation ceremony.

I went back and read the final sections of all seven books and, even at the "end-of-year" or "leaving" feast (the final celebration in the spring is called the former in the first three years and the latter after year four), there is absolutely no mention made of graduation, no congratulations offered to students who had completed their studies, no celebration of the class of students that is leaving Hogwarts to begin their careers.

In year one, Harry attends the end-of-year feast and Dumbledore's reported comments focus only on the House Cup and awarding additional points to Harry and crew.

In year two, Harry also attends and we only read about Hermione's return, Gryffindor winning the House Cup for a second year in a row, exams being cancelled and Gilderoy Lockhart not returning in the upcoming year.

The report on the end-of-year feast after year three is even shorter, with confirmation that Gryffindor won the House Cup yet again.

In year four, perhaps not surprisingly, the much longer scene focuses on the death of Cedric Diggory and the return of Lord Voldemort. No mention of the winner of the House Cup at all.

At the end of year five, we are not even sure if Harry made it to the feast since, devastated at having lost Sirius Black, Harry is first distracted by Nearly-Headless Nick and then by Luna on his way to the Great Hall.

There is apparently no final feast in year six since the focus is on the death of Dumbledore.

And, of course, there isn't even really a school year for Harry, Ron and Hermione in year seven since they are on the run for the entire book, returning only for the Battle of Hogwarts at the very end.

It's interesting that Rowling paid so little attention to the fact that seventh-year students were actually graduating from her beloved school.

And perhaps even more interesting that each of the last four books ends with a significant death: Cedric, Sirius, Dumbledore and finally Voldemort.

I don't have any brilliant thoughts or insights into why this may be but I do find it interesting.
