I can't tell you specifically about K because we moved here after all our kids were out of kindergarten, but we love the school. It does have art, music and PE, as well as band, chorus and strings in later grades (and chamber strings and chorus for kids who are seriously good). Because the school is large (close to 900 kids I believe this year), the kids eat lunch and have recess in shifts by grade. The little ones bring a mid-morning snack up through 4th grade to make sure they don't get hungry.
Our kids are all very different personality-wise and academically, and we've just been amazed by how approachable the administrators are and the care the principal and her staff take to listen to parents' input when deciding things like classroom placement. Teacher-wise, we've had a couple we didn't care for, several good ones, and a probably higher than average number of outstanding ones. Tje PTA is very active and organizes a lot of activities--the only one they don't have and I wish they did is a science fair, which my older kids had at schools before we moved here and loved.
