Study In-Person at an Accredited Teaching Centre
Gem-A Accredited Teaching Centres (ATCs) are institutions, colleges and schools that have been approved to teach Gem-A courses using our course notes and equipment. They make it possible for students to have on-site, face-to-face tuition in their own region and, in some countries, students can study in their own language. Our course notes are available in English, Simplified and Traditional Chinese, Japanese and French.
