There is an amazing opportunity to teach English and be trained as a volunteer supervisor through the Ministry of Education in Mexico. It is an internship that includes free housing and opportunities to take on paid tutoring jobs in the evening for spending cash. This is a unique opportunity to work in the public school system in Mexico which is heavily unioned and otherwise closed to international teachers.
