Can't agree more, I had to read it twice for school: once freshman year of high school and again sophomore year of college. I absolutely did not understand it in high school and found the entire story completely boring except for the trial.

When I read it later I was in awe of how much the nostalgia of Scouts childhood affected me. Made absolutely no sense to read it when I was still a child.

I feel like teachers/schools see a "kid" protagonist and forget that its technically Scout as an adult looking back on her childhood.
