What Parents Should Know

At 5.7:1 students to teachers, Dalton School sits well below the national average. Smaller classes like that usually mean more one-on-one time between students and teachers.

Dalton School is private, so it runs independently of the local district and sets its own curriculum. That freedom cuts both ways depending on what you want for your child. If you're considering it, start with the practical questions: tuition, financial aid, and how admissions work.
