***** NOT A TEACHER *****
"She went to school" uses the past tense because it is something that happened in the past.
One uses the present perfect if it STILL touches the present time: "She has lived in the country for most all her life." (She started to live in the country at a certain time and she is still living in the country at this moment.)
I, for example, lived in the central part of California when I was a child, but I have lived in Southern California since the 1940s.
