I have just graduate from grade 12. Can I join a teacher training course and become a teacher?

Teachers need a bachelors degree and a diploma course in pedagogy as per the new regulations. To join a training program there is no such requirement and after finishing 12^th grade, you can join for a diploma course.

Yes, you can do CACHE Level 2 programs and apply to become an assistant teacher in Nurseries in UAE. How ever school teaching jobs needs a minimum of bachelors degree inorder to be eligible for applying visa.
