  • Among "All-Boys Schools", view the boarding schools with the smallest average class sizes (2018-19).
  • Keep in mind that small statistical differences in average class sizes between schools do not always indicate better student performance at one school or another.
  • Also keep in mind that boarding schools in general have smaller average class sizes than public schools - even for schools with larger class sizes, a "large" class in a boarding school would still often be considered small by public school standards which often have class sizes of 20 students.

The heritage and ideals of the Marine Corps are passed on to the Cadets at the Marine Military Academy by a staff of former Marines who live their lives by these principles. Honor, courage and commitment are but three core values the staff and faculty preach to the young Cadets at MMA. The military setting eliminates distractions, improves personal accountability and enables Cadets to establish and focus on their future goals. The Marine Corps JROTC program develops informed citizens, strengthens character by teaching discipline and develops an understanding of the responsibilities of citizenship.
