CMASAS gave me the greatest high school experience I could have asked for! The teachers and faculty work closely with the students to give them the best education they can, tailored to their specific learning needs as well as their interests.


I went to CMASAS from sophomore through senior year of high school and the experience that I had was invaluable! The faculty is highly professional and very supportive.


One thing I have to say about CMASAS is that there is a great deal of student/teacher interaction. I attended another online school my freshman year of high school and I rarely had my questions answered within an acceptable time frame.
