Leadership training is one of the cornerstones of cadet life at SJNMA. The goal of the Academy is to prepare each of our cadets for success in life by instilling in them a solid work ethic, an understanding of the value of integrity and teamwork, and the ability to think critically, communicate well, and function in a diverse and ever-changing world.
The spiritual and character development program fosters personal growth and a sense of community at SJNMA. Cadets have the opportunity to explore their spiritual growth, practice their faith traditions and serve their community on a regular basis.
The community of SJNMA is comprised of global cultures, backgrounds and languages. Approximately one-third of our cadet population is international and the rest of the Corps is from all over the United States.
The Aviation Science program at SJNMA offers high school junior and seniors interested in aviation the opportunity to earn their private pilot’s license as part of the accredited academic curriculum. This unique opportunity is a natural stepping stone for those interested in degrees in aviation-related majors and aerospace.
SJNMA features four, one week themed sessions of high-energy summer camps for young men ages 11-16 that are designed to promote leadership, self-confidence, teamwork and physical endurance while having fun. All camps feature the Academy’s popular activities such as paintball, rappelling/rock climbing, 'THE MUD PIT,' marksmanship, obstacle course, water survival and archery to name a few. In addition, SJNMA offers a five-week summer academic program for young men entering grades 7 to 12 that provides them an opportunity to advance in their academics while developing character and leadership skills in a military, boarding school environment, and to provide the best learning environment possible while supporting the student for success.
St. John's Northwestern Military Academy has been shaping the minds and developing the character of young men since 1884.
Academy alumni have attended notable colleges and universities.
As a college preparatory and leadership development boarding and day school for young men in grades 6 through 12, St. John's Northwestern provides a distinctive educational experience for its cadets that focuses on academic success, athletics, leadership development and values.
Surrounded by English gothic-style architecture, broad lawns and towering trees, cadets living within the 110-acre campus are immersed in a safe and secure environment in which they build self-esteem, self-discipline, academic focus and intellectual curiosity that allows them to "work hard, play hard, pray hard.".
