Miss Jennifer Honey is Matilda's teacher at Crunchem Hall Primary School. Miss Honey is young, pretty, mild-mannered and "possessed that rare gift for being adored by every small child under her care." (p. 67) Later in the story, she becomes a great advocate for Matilda.
Miss Truchbull is undoubtedly the most colorful in the cast of Matilda characters. The Headmistress at Crunchem Hall Primary School, Miss Trunchbull serves as the "head teacher, the boss and the supreme commander" (p. 66) who "insists on strict discipline throughout the school." (p. 69) Dahl also describes her as a "gigantic holy terror, a fierce tyrannical monster who frightened the life out of the pupils and teachers alike" (p. 67) who "hardly ever spoke in a normal voice." (p. 85) Instead, he says she "barked or shouted." (p. 85) Miss Trunchbull's favorite form of punishment is to send students to the "Chocky," which is a "very tall but very narrow cupboard" that has a floor "only ten inches square so you can't sit down or squat in it" - forcing one to stand, instead. Furthermore, "three of the walls are made of cement with bits of broken glass sticking out all over, so you can't lean against them." Leaning against the door is also impossible, because it has "thousands of sharp spikey nails sticking out of it." (p. 104) Much later in the book, we learn that Miss Trunchbull is also Miss Honey's aunt Agatha.
Lavender, Nigel, Ruper, Eric, Wilfred and Hortensia are Matilda's friends and classmates at Crunchem Hall Primary School.
Amanda Thripp is another classmate. She makes the mistake of coming to school wearing her hair in pigtails. Miss Trunchbull despises pigtails, and so she uses them to pick Amanda up. Using her Olympic hammer training, Miss Trunchbull swings Amanda around over-head and throws her clear across the school yard fence. Luckily, she "landed on the grass and bounced three times and finally came to rest." (p. 116)
Bruce Bogtrotter is yet another of Matilda's classmates who suffers under Miss Trunchbull. This 11-year old boy commits the crime of sneaking a piece of the Headmistresses' "special" chocolate cake. During his confession, Bruce admits that he found the cake, baked by the school's cook, to be "very good." (pp. 122-123) As his punishment, Bruce is forced to eat every last bite of a duplicate cake which was "fully eighteen inches in diameter" and "covered with dark-brown chocolate icing." (p. 124)
Mr. Trilby is the Deputy Head of the school who, at the end of the book, is appointed Head Teacher in Miss Trunchbull's place.
Miss Plimsoll is Matilda's teacher once she is moved to a higher grade at the school.
