As well as the various students around Bullworth Acadmey, there's all sorts of faculty members to affect Jimmy's academic career.
It's not just limited to the teachers, either; there are other staff members who'll have their own impact on your school days.
Teachers
Mr. Burton
The Gym teacher. A former pro footballer, Mr. Burton has some rather strange interests in "laundry", and often hits on the female students (or tries to).
Dr. Crabblesnitch
The headmaster of Bullworth Academy. He doesn't actually teach any classes, but does take an active (although not always positive) interest in the academic career of Bullworth's more troubled students.
Mr. Galloway
The English teacher. Mr. Galloway has a drinking problem that's only known to a few people, but he's in danger of getting fired over it. He is romantically involved with the Art teacher, Ms. Philips, and is particularly fond of Jimmy.
Mr. Hattrick
The Math teacher. Mr. Hattrick is extremely unpopular at Bullworth, both among the students and the staff, for his arrogance and self-righteousness. He has a particular dislike for Mr. Galloway, and is determined to get the English teacher fired. Mr. Hattrick has also been known to sell test answers to some pupils.
Mr. Neil
The Shop teacher. He doesn't like to talk much, preferring that his students just shut up and get on with their work.
Ms. Philips
The Art and Photography teacher. Ms. Philips is one of the few people to know about Mr. Galloway's drinking problem, and helps Jimmy cover it up.
Dr. Slawter
The Biology teacher. He's rather morbid, and enjoys taxidermy in his spare time.
Dr. Watts
The Chemistry teacher. His mental state seems a little fragile, and he's often forgetful.
Mr. Wiggins
The History teacher. Mr. Wiggins can be seen walking around the school grounds, but he has no involvement in the plot of the game.
Other staff
Mrs. Carvin
The school librarian, Mrs. Carvin has a pathological fear of rats.
Miss Danvers
Dr. Crabblesnitch's secretary. She's somewhat two-faced, being very polite in front of the headmaster but ruthlessly aggressive when he's not around.
Edna
The unhygienic lunchlady. She's got a thing for the Chemistry teacher Dr. Watts, and isn't above using pupils to help her out with manic schemes to bed him.
Mr. Luntz
The janitor, Mr. Luntz also works in the Bullworth Academy's clothing shop.
Nurse MacRae
The school nurse.
Mrs. Peabody
Hall monitor and girls' dorm mother. She hates Jimmy, and comes down especially hard on him if he's caught trespassing in the girls' dorms or bathrooms.
