Kimball Union Academy, or KUA, is a private boarding and day high school that offers students in grades 9 through 12 or a postgraduate year with a transformative college-preparatory education that places individual growth and development at its core.

As one of the oldest boarding schools in the nation, KUA is rooted in history, yet unbound by tradition. Innovative in nature and forward-thinking in our approach, we stay true to our mission to create a deep sense of belonging for all members of our community as they develop the knowledge, voice, and character to live with purpose and integrity.

Strong relationships form the foundation of our academic and co-curricular programming. We leverage everything we know about the science of learning and how the brain works to design intentional experiences and challenges that meet you where you are. Along the way, you’ll be supported by our exceptional faculty, advisors, and coaches who are highly invested in your growth.

This all takes place on our 1,300-acre campus nestled in New Hampshire’s Upper Valley – an ideal educational environment that offers students access to the outdoors and distraction-free study, as well as rich cultural, intellectual, and recreational opportunities.

Applications are due February 1. To schedule a campus tour for you and your family, just call our Admission Office at 603-469-2100 or email You can also learn more online at
