When did Jem and Scout get out of school in the book To Kill a Mockingbird?
The novel covers about three years of Scout's life. When the story begins, it is summer. She and Jem meet Dill in Chapter 1 and he leaves in Chapter 2, when Scout starts school for the first time.
Scout's first year of school is over in Chapter 4. Coming home from school, Scout and Jem find another gift in the oak tree. Dill arrives two days later. This summer the kids are still fascinated by Boo Radley. On Dill's last night in Maycomb, the three of them try to get a look at Boo at night. Jem loses his pants in the attempt and Dill leaves for the next school year.
Scout's second year of school starts at the beginning of Chapter 7. Scout and Jem continue to find things in the oak tree, noting that the mysterious giver must be setting things out while they are at school.
Chapter 11 marks the end of another school year and the beginning of the next summer:
There was a hint of summer in the air—in the shadows it was cool, but the sun was warm, which meant good times coming: no school and Dill.
This summer, during which the trial occurs, extends from about Chapters 11 through 24. The trial is one of the most significant parts of the novel and therefore takes up a large portion.
