The Irish setter arrived at Tavistock College in Plymouth in England when she was just nine-weeks-old.
The puppy is said to have an ability to work out if students are stressed, and can help calm them down, the Daily Mirror reported.
She is on hand during exam season to greet nervous students and also attends staff briefings.
"From the very first she has loved her work - she will trot jauntily down the corridor, tail wagging, looking out for children, and staff, to make a fuss of her, Plymouth Herald, headteacher Sarah Jones, said.

"Before one exam we had a student so stressed she felt he couldn't take the exam, but meeting Shola brought a smile to her face and she was then able to go in to sit her exam," Jones said.
"In a class with some students known to be worried and anxious, Shola will invariably choose to sit beside those students rather than the other, calmer, students.
"College life fascinates her - last week she discovered the college chickens and was riveted to the window watching them peck and scratch in the straw the other side of the glass," Jones said.
Shola's name was chosen from more than 300 suggestions put forward by students and she was presented to the college in assembly.
