  • 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.

    Marine Military Academy
    Marine Military Academy Photo - MMA’s Academic Department includes 29 full-time faculty members—19 men and 10 women. All faculty members meet or exceed Texas state teacher requirements, and several members of the faculty hold advanced degrees. Drill Instructors are considered adjunct faculty members and work closely with the Academic Department. DIs are all retired Marine chief warrant officers or senior staff noncommissioned officers who live in an apartment in the barracks with their families. The Dean, John D. Butler, has a MBA from University of Texas at Pan Am, a B.S. from Texas A&M University, a M.Ed. in educational administration from the University of Texas at Brownsville, and an Ed.D. in curriculum and instruction from the University of Houston. Dr. Butler joined MMA in 1996 and is a veteran of the U.S. Army. With the 2011-2012 academic year Environmental Science, Cinematography Arts, and Mandarin IV have been added to MMA’s curriculum to provide high quality, educational choices for our cadets as they prepare for higher education. Of course, the cadets, faculty, and staff continue to be the key to MMA’s ongoing success. As we are all aware, technology and discovery create new knowledge at a near exponential rate. What is found between the covers of a textbook today is likely incomplete or incorrect by the time it reached publication. Marine Military Academy cadets are prepared to deal with this phenomenon successfully because they have developed within themselves the ability to think…problem solve…and convert data into useful information. They do not rely on rote memorization and the recitation of facts to succeed. The Marine Military Academy faculty understands that the material presented, the presentations made, and the assignments collected are merely toolsfor developing those qualities within our cadets required to negotiate a rapidly changing environment and lead those less fortunate in the process. The faculty stand at the front of the class, not as lecturers so often encountered within schools, but as examples of integrity, responsible citizens, and leaders. Cadets are not passive vessels in the classroom but an active and integral part of the educational process. Marine Military Academy cadets take responsibility for themselves and their classmates as they navigate their way to the college of their choice.
