This article is a list of characters from the British TV series Teachers.^[1][2][3][4]

• Gillian Bevan – Clare Hunter, the headmistress. Usually provides the staff with their topic of discussion for the episode (disabilities, age awareness etc.). Had a brief fling with Bob. Was renowned for her iron-like nature, as exemplified with her no-nonsense approach towards Carol and the "Come In" buzzer which sounded on the opening of her office door. Clare can often be very sarcastic and cutting, but shows another side to herself when she goes through the menopause.
• Ursula Holden-Gill – Carol Schicklgruber, one of the school secretaries. Speaks very rarely and incoherently, apart from when repeating something that Clare has said, when her impression is perfect (Series 2, Episode 5). Had a brief relationship with Kurt, and it is suggested they got back together after the second series, though they are not together in the third. Carol is pregnant at the start of the third series, and the father is unknown. The baby is born later in the series and is regularly accidentally left behind by Carol in various locations. It is eventually revealed that the baby is part Chinese, thus not Kurt's. It is revealed by Lindsay in Series 4 that the maths teacher Mr. Chong is the father. Carol's surname "Schicklgruber" is the same as the original surname of Alois Hitler, father of Adolf Hitler.
• Lloyd McGuire – Bob Porter, the previous head of English. Though initially a relatively minor character (his role in series 1 was as an authority figure who would get on Simon's back about incomplete work), by Series 3 he had developed into a main character, almost one of the gang (though he was repeatedly made fun of and generally disliked) and most of his scenes revolved around his buffoonery or foul mouth. When Summerdown and Wattkins merged at the beginning of series 4, he lost his position to Ewan, whom he loathes. He ordered a bride from Thailand (Ping), who later had sex with Ewan. Ping dumped Bob at their wedding reception. His first wife - Yvonne - left him for "the satellite installation man" in series 3. This was because she was not satisfied with their sex life, after a brief revival, due to the series 2 Christmas party.
• Ellen Thomas – Liz Webb, one of the school secretaries, known for her witty and acerbic put-downs. Her daughter, Kayla, was in Brian's class in series 2 and 3. Despite being married, she had a one-night stand with Kurt, and an intense affair with Bob for a few days after the Bonfire Night Disco. Liz sees herself as being much more powerful than she is, and tries to assert her imagined authority over the staff whenever she can.
• Jonas Armstrong – Anthony Millington, a student who has a brief affair with Penny, who originally thinks he's a teacher. He dumps her after deciding that he needs to focus on his school work, after which she tries to make his life miserable. He then mentions the affair to Liz to try to get Penny off his back, but they reconcile before any news of it gets to the headmistress. The two get back together at the end of series 4 when the school year ends because she says she will miss him and wishes for him not to go.
• Su Bhoopongsa played Ping, Bob's Thai bride. Bob and she made contact through a website in series 4. When she arrived, she had sex with Ewan in his office, without Bob knowing. Bob married Ping in the final episode, but she left him, because she only wanted British citizenship.
• Jason Boyd — Grint, a prematurely-balding student in the third and fourth series. He was frequently made fun of by the teachers in their attempts to work through the problems they face in each episode. He had an episode focused on him when he was found "wanking in a cupboard" by Damien. He is a practising Buddhist and also was seen to be a member of the 'Aryan Society' along with Carol the school secretary, in series 4 which Penny is invited to join.
• The Canteen Dwarves – Although the very first episode features tall dinner ladies, many of the school's canteen staff are dwarfs, for no apparent reason. They appear as background characters in various scenes, seldom speaking or interacting with the teaching and administrative staff. Dramatically, the Canteen Dwarves are used to perpetrate many visual jokes, running parallel to the (spoken) dialogue of the main characters, usually at the bin-yard behind the school kitchen. For example, whilst some teachers have a sly smoke between lessons, a dwarf is seen climbing out of a large industrial rubbish bin. A few moments later, another dwarf follows. The teachers appear oblivious.
• Peter England played Arnie, a pupil in Simon's class in Series 1 and returned as a sixth former in Series 2. Arnie would often be found smoking with Simon behind the school, often having to listen to Simon moan about the worries in his life. In Series 1 Arnie bribed Simon into giving him straight A's in return for taking the blame when drugs were found.
• James Corden played Jeremy Stevens, probably the smartest pupil in Simon's year 11 class. He would always worry about Simon's lack of "proper" teaching and loved being tested, much to his classmates' dismay. He disappeared after Series 1 and returns in Series 3, as a sixth former, when Simon returns from travelling and quizzes him on the places he went.
• Damien Goodwin played Alec, the school psychologist. He had a relationship with Jenny. Kurt, Brian and Simon usually came to him for advice, which didn't please Susan. Jenny broke up with him because she thought the relationship was getting boring.
• Ashley Madekwe - played Bev, a loud mouth student in series 1 whose story-lines evolve mainly around her pregnancy. She gives birth towards the end of the series with Simon delivering the baby in the school's toilets. She briefly comes back in series 2 to talk about her experiences as a teenage parent, prompting Susan to consider artificial insemination.
• Zoe Telford – played Maggie, the police officer girlfriend of Simon. Dumped by Simon in the final episode of series 1 after he slept with Jenny, she is not seen again.
• Phoebe Thomas played Cheryl Cassidy, Pauline's friend and also a year 11 pupil in Simon's class. Dumped her boyfriend following Simon's advice after he wouldn't have sex with her but later realised this was due to him catching crabs off her friend Pauline. She only appeared in Series 1 with no explanation to her departure.
• Kara Tointon played Pauline Young, a year 11 pupil in Simon's class and friends with Cheryl. Pauline slept with Cheryl's boyfriend and gave him crabs, which Brian accidentally revealed. Also "complained" when Bob stared at her breasts during French. She only appeared in Series 1 not returning for Year 13 to work for her dad in an office job.
• Liz White played Eileen, a dinner lady who spends the night with Simon and in a later episode goes on a date with Brian in series 3.
