A framed diploma on a bookshelf at the Protagonist's House, as seen in the beginning of Fallout 4

A framed certificate in the Protagonist's House in Fallout 4.

Can be seen on a bookshelf near the hallway.

Diploma reads:

"Suffolk County School of Law

Boston, Massachusetts"

The diploma presumably belongs to Nora, which indicates that she is a lawyer. The books around the diploma appear to be law books.

Next to the diploma, there is a display case with a Veteran Flag, presumably Nate's.
