Notice Regarding Enrollments for the 2020-2021 School Year

All enrollments are now closed.

We would like to thank everyone for their understanding in that we are unable to handle additional enrollments at this time. We had originally planned for 425 full-time enrollments with a capacity for 450 during our planning meetings in February. As we discovered that a Pandemic would be changing the world and especially education, we increased our capacity to 550 students to meet the demand while still being able to maintain our Personalication Philosophy. We will have limited enrollments available starting January 2021 for all grade levels. We understand some may be disappointed in not being able to enroll, however, it is a far better scenario than enrolling your child and not being able to provide an exceptional educational experience.

CMASAS Difference

Extensive Electives

Extensive list of high school electives for students with varying interests.


Mastery based assignments and assessments.


Instructor response within 24 hours and mostly same day (includes grading, assignment feedback and response to email/phone communications).

1 To 1

1:1 student teacher interaction.


Which is more than just reading and answering multiple choice questions, with assignments which allows students to show what they know in the learning style they prefer.

Personalized Education

Students have the opportunity to complete assignments based on the learning style in which they learn the best. This approach takes a commitment from both the instructor and student to develop alternative assignments which cover the learning objective and concepts being taught.



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.
