What Parents Should Know

Kellenberg Memorial High School is a large school: 2,549 students. Size usually brings more course choices and activities than a smaller school can staff, but kids can also blend into the crowd. Ask how the school keeps students known and supported.

Kellenberg Memorial High 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.
