Dr. Edward Dudley Tibbits established Hoosac School to provide an intimate, highly personalized educational setting in which each student could receive individualized attention and support.

Today, the School's essential mission remains true to its founder's philosophy: to develop the character, spirit, mind, and body of its students, to foster independence and self-discipline, and to motivate them to develop to their full potential for success in college and for full, productive, and intelligent lives. Founded as an Episcopal church school for boys, Hoosac today retains its ties to the church through the Chapel program while welcoming young men and women from many religious backgrounds. Students and faculty pledge to conduct themselves according to the School's Code of Honor.

Hoosac School is a nonprofit corporation governed by a Board of Trustees. It is chartered by the New York State Board of Regents and accredited by the Middle States Association of Colleges and Schools. Many of the 1700 living graduates support the School through the Annual Giving. Eight alumni currently serve on the Board of Trustees.
