This monograph is one of APCEIU's EIU Best Practices Series, which aims to encourage educators, scholars, and activists to implement and share local initiatives on EIU. The Series No.39 introduces the Training of Trainers (TOT) program, a workshop for teachers to better incorporate GCED/EIU concepts into respective curriculum and school environment. Upon participating in the APCEIU training workshop, Mr. Yeshi Dorji from Dungtse Middle Secondary School in Bhutan sought to create a forum in which teachers and school officials can learn to incorporate GCED. Such exemplary initiative not only enhances capacity building of educators in the school, but also has potential to have larger impact in the local and regional communities.
