The school already fired him.   No school would ever hire a teacher that has had sex with a student.   Do you not realize the liability they would place upon themselves if they did that?

Besides, he deserves to never teach again.  That is a most severe abuse of authority.  And he is more than young enough to start a new career.   So starting over in a new career is no problem by itself.

But I don't honestly see what making him a registered sex offender and putting him in jail accomplishes.   That will really have a most severe impact on his life, and make it difficult to get employment.

Having him lose his career of being a teacher is enough punishment in my book.
