Our narrator is Scout, a girl who will grow from age 6 to almost 9 during the story. What do you suppose we, as the readers, should be aware of as we listen to Scout tell her story? Is a child a reliable or unreliable narrator?

It is important to understand that Scout is writing this story as an adult through the point of view of a child. The fact that she is an adult reflecting on her childhood experience gives her a certain credebility as a narrator. The text is often punctuated with observations from an adult point of view. Young Scout, however, is a reliable narrator in her own right. She exudes a sense of social justice that reflects her father's world-view.

First of all, as Aslan points out, the story is written by an adult; not a child as you suppose. Most importantly, this adult is writing about her life - a life she really lived. In my opinion, she has a lot of credibility
