The main RuneScape Wiki has an article on: Examiner
The Old School RuneScape Wiki also has an article on Examiner.

The Examiner is a non-player character involved in the Digsite quest. She provides the player with an unstamped letter of recommendation, a trowel, and performs the first test (which the player fails, and must learn the answers from students).

Her examine text is an amusing pun.
