If you want to know what makes us different, it’s our teachers.

Our teachers are the foundation of iCademy and the growth of your student. They are talented, passionate, patient, and specially trained to excel in all the subtleties of online teaching. iCademy teachers are drawn to virtual schools because they know kids are different and learn in different and unique ways.

iCademy has a teacher led structure, so our teachers are leaders in their teaching and in making decisions about our school through what we call a School Responsibility (S.R.). Check out their information below.
