Very good education
I love that my children are learning and meeting new students and teachers. Their education has improved greatly since started in the beginning of school. They have been able to learn more from the previous teachers and plus more. We can’t wait for what you all have coming for the next school term.

Convenient and enjoyable
Overall it’s been a very smooth and enjoyable experience. The teachers and other staff make sure the students are kept on task and completing their work. And it’s a very convenient way of learning. No commute except for testing at the end of the year.

The BIGGEST thing I love about COA is the staff. I have NOT had one yet that didn’t make me feel like they had my families best interest at heart!! They are a phenomenal group of teachers and administrators. I wish this option was available for my children when they were in school but I am thankful my grandchildren have this opportunity.

Great virtual learning
Carolus Online Academy has thus far been a tremendous good experience for my 6th grader. This is our 2nd year attending and he has improved in his academics. He also receives speech and o.t services as well as tutoring. I love the platform and the schedule they have set for him to accommodate his learning style.

Carolus was just what my granddaughter needed. She’s not shy, but she has a lot of health problems which made it hard for her to be present in a class. Most teachers made it very comfortable and were very understanding. There were those few exceptions, as in every walk of life, that had strict rules and would not bend them for anyone or anything. I’m not saying that’s bad it’s a fact of life. Thank you for being there when you were needed (and for understanding that our Wi-Fi is not really sufficient for extended use as we are away out in the country). Overall, it has been a great learning experience. Thank you again.
