About Crimson Global Academy

Crimson Global Academy (CGA) is a world-leading online school with students in more than 30 countries and a teaching staff drawn predominantly from New Zealand, Australia and the United Kingdom. Every one of our teachers is a subject expert, and our strong pastoral care network ensures students learn in a safe and inclusive environment.

Students at CGA study at a level that matches their academic competence rather than their age, which means a significant proportion of our cohort is working ahead of their peer group. Combined with curriculum flexibility, cutting-edge technology and the opportunity to accelerate, CGA offers an unusually rich environment for students with the drive to excel. Our academic results speak for themselves.

Transforming the way students learn is central to what we do, and we are rapidly integrating AI to support student learning in meaningful, classroom-ready ways.

Please note: you must hold a New Zealand teaching registration to qualify for this position.
