Accredited Teaching Centres (Worldwide)

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 benefit from studying in their own language: our course notes are available in English, Simplified and Traditional Chinese, Japanese and French. Use the map above to see if there is an ATC near you or click on one of the countries below to find out more.

Are you a school, college or university that is interested in becoming a Gem-A ATC? Contact education@gem-a.com to find out how to apply.
