The following are the main characters of the novel To Sir, with Love by E. R. Braithwaite:

Ricardo Braithwaite: Ricardo, who is also referred to as “Rick,” is the main character in the story. He was formerly an engineer before joining the air force during World War II. After the war, he tries to find work but is subjected to racial discrimination. However, he does not despair, and he eventually lands a job as a teacher. His students are semiliterate and do not show much interest in learning. He turns to unconventional methods of teaching by allowing students to visit museums and decide what topics they want to discuss. This approach becomes popular with the students, and they end up loving Ricardo Braithwaite.

Mrs. Grace Dale-Evans: Mrs. Dale-Evans is a teacher in charge of the domestic science department and introduces Braithwaite to other teachers. She is a staunch advocate for cleanliness among her students. She even cleans the staff lounge and helps one of the students to bathe after the student is neglected by her mother.

Alex Florian: Florian is the school headmaster and is described as small with large eyes and a head full of white, curly hair. He welcomes Braithwaite into his office when Braithwaite first reports to the school. Florian outlines the various circumstances surrounding his students and gives his word that he will not interfere with Braithwaite as long as he operates within the outlined guidelines.

Miss Gillian Blanchard: Miss Blanchard is the newest among the teachers and the prettiest of them all. She volunteers to accompany the students on their various trips. Gillian and Braithwaite become close and fall in love. At first, Gillian’s parents disapprove of their relationship, but the two later get engaged.

Pamela Dare: Pamela is a girl who runs into Braithwaite in the hallway. She is one of the cleanest and neatest students in the class. When Mr. Braithwaite asks for someone to read for the boy who was making fun in class, she volunteers. She is quite eloquent, which makes other students not want to read after her.

Miss Vivienne Clintridge: Everyone refers to Miss Clintridge as “Clinty.” She is an art teacher with a kind heart. She brings Braithwaite a cup of tea and wants to know how he fared in class. She also tells Mr. Braithwaite that most of the students come from homes that experience a lot of violence, which makes many of them disobedient.

How would one go about describing the main characters in To Sir, With Love?

Braithwaite is the central character of the narrative.  His character can be seen as one striving to find meaning and not afraid to use his freedom in order to do so.  Braithwaite is defined by his fluid understanding of the world, and a resistance to settling in to a condition that he knows is not satisfying.  His courage to embrace freedom as a form of innovation is not only what helps him find happiness, but is what makes him an effective teacher.  Mr. Florian is the representation of the evolved teacher, whos philosophy of understanding children in a non- punitive setting is one that not only defines him as a headmaster but represents an ideal that most teachers cannot reach.  His position and beliefs are a jarring shock to Braithwaite's first experience with his students, who prove to him the need to formulate his own philosophy before embracing others'.  Denham is a very strong force amongst the students.  His leadership and unwillingness to be persuaded through superficiality is what defines him.  Braithwaite learns quickly that he has to find a way to bring Denham into his corner or simply move past him, as he will not be successful in challenging him.  Pamela Dare is struggling to find meaning in her world.  She struggles with finding attention from her mother and from Mr. Braithwaite, and while she is emotional about this need to be validated, she understands what true commitment is and true understanding of people through her revelations brought about by Braithwaite's teaching.
