CMASAS message Regarding COVID-19 Related Enrollments

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 mid-year enrollments.

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.  All new enrollments will be processed with a start date of April 20, 2020 to provide our staff time to be with their family during our Spring Break.

If you are looking for a temporary enrollment option for your family, we recommend enrolling in our Flex Plan.  We have reduced the registration fee to $150 under this plan for a pay as you go six-month term. Regardless of the number of courses desired, the Flex Plan meets your needs at an affordable price while providing students and families with the exceptional support of one of our Personalized Education Coaches.

We deliver what other programs can't - we are an accredited institution that provides a personalized learning experience tailored to each individual student. We differentiate ourselves from other online schools by not just making the ordinary exceptional, but through our Personalized Philosophy which drives everything we do.

CMASAS has recently been recognized as being in the top 10 of the 50 Best Online High School Diploma programs named by The Best Schools - an independent website that ranks schools on quality based on a number of criteria including accreditation, academic success rate, personal attention, and cost.

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.
