CMASAS Message Regarding Enrollments for the 2020-2021 School Year

Our hearts go out to all those directly affected by the Coronavirus.The recent CDC recommendations and various school closures around the country have resulted in an increased call volume for potential new enrollments for the 2020-2021 school year.

Our Personalication Philosophy provides for open enrollment year-round and several of our staff have offered to take on additional students during this national and global crisis.  We are now accepting new enrollment pre-registrations for the 2020-2021 school year. A Registration fee and 1st month tuition payment is required to pre-register for next school year. If you are unsure of which tuition plan is the best fit for your situation, please schedule an Information Call or call to speak with one of our enrollment counselors directly.

Please Note: The CMASAS office will be closed July 3rd, 2020 for 4th of July weekend. We will respond to all messages on Monday July 6th.

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.
