100% of all TET employees have undergraduate higher education qualifications with 70% having a master's degree or above or senior staff titles. However with the increase of foreign companies, personnel and technological exchanges, business exchanges in China, TET found that not only do US and European companies use English to communicate but the Asian countries now use English as their primary language for conducting business abroad. These countries included Thailand, Indonesia, Malaysia which are all major trading markets for TET.

TET has thus made English proficiency a top priority. At the request of the staff, TET has developed English Staff Training Seminars. Other initiatives include English Open Mouth Meetings and English Reading Classes. This helps TET create a good spoken English learning environment.
