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.


Rachel - Current CMASAS Student

Having gone to Christa McAuliffe School of Arts and Sciences before, I know that they're really good about helping the students and caring for their educational needs. But after two years at that...delightful place, this amazes me. At my other online school, you weren't even allowed to skip a lab if you already understood the concept, and now here I am at a different school where they're willing to alter the entire course to make it more practical-science-y. I can't even express how much I love this!! Putting the passion and love back into learning!

CMASAS Student

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.

CMASAS Student

CMASAS DEFINITELY lives up to the goals they claim. Many of the classes definitely can be challenging, through-provoking, and inspiring. The only time a class is going to be easy is if someone already has the knowledge of it, but needs to go through that class to get to the more advanced level. Of course, that's where the personalized classes come in!

An Experiment in Gratitude: The Science of Happiness

An Experiment in Gratitude: The Science of Happiness

August 30, 2016

Adults will tell you: Adulting is hard. Paying taxes, making money, having to choose between fixing the sink or funding your Star Wars collectable habit, all these things are hard. But let’s be honest: life is hard, no matter your age. There’s always something we’re trying to figure out. As a young adult, your formative years are one long struggle of trying to find out who you are and what you want from life. When you’re an adult, your life is spent trying to stay true to yourself while maintaining adult responsibilities. So when we’re constantly wading through the river of life, not knowing what’s beyond the bend, how can we stay happy? This video via @SoulPancake has an idea: Gratitude. They gave a written test on several volunteers, then asked them to write a letter to someone who had greatly influenced their life. Afterward, they asked the participants to pick up the phone, call that person, and read their letter out loud. Before leaving, the test was given again with a different format, so it didn’t look the same

The Power of Introverts

The Power of Introverts

August 11, 2016

I am an Introvert. I am an Extrovert. I am in-between. Which one of these sentences resonated with you? It’s actually quite important to know which you are, not to nail yourself into a box, but to learn how to harness the unique power you have inside you. How do you re-charge? When are you the best version of yourself? If you find that you feel the most inspired and connected to yourself when you’re alone, if you have to gear up to be in large groups of people, if you enjoy solitude and quiet reflection, you may be an introvert. If you find that your batteries charge in large groups of people, if you’d rather be out than at home, if group collaborations are how you get inspired, you may be an extrovert.
