A Letter from our Director of Student & Residence Life

Welcome to Cotter's Boarding Program!

Since 1911, Cotter Schools has been providing an exceptional experience and strong foundation to prepare our students for a lifetime of learning and growth. Cotter has been offering boarding services for international and domestic students for over 20 years. We currently offer boarding options for student in grades 7-12. 

Cotter offers exceptional academic programs, athletics, fine arts, and extra-curricular activities. We are also committed to providing our students with best-in-class facilities. In fall 2021, our boarding students will enjoy a brand new dorm and cafeteria!

Cotter offers a challenging academic environment filled with experiential learning opportunities! As a student-centered school, our teachers prepare students through personal attention and small class sizes. Through project-based learning you will frequently interact with fellow students and teachers. 

Cotter is a global community where you can expect to feel supported by your teachers, fellow students, and staff. At Cotter, we are a family that embraces our diversity and the different cultures present in our school.

At Cotter, our residential program provides for an on-campus living experience while having activities that allow you to meet local students that allows our students to enjoy their Cotter experience!
