I consider English my native language as it is the first one I learned since I was born, as have my parents. Nevertheless, my family has traveled a lot, and I hold nationality and citizenship in countries where English is not a main language.
For this reason alone, I am required to submit IELTS or TOEFL when applying for graduate programs around the world.
Since I would like to teach privately (to support my wallet during Master studies), I was pondering whether it would be worth to pursue one of those English teaching
certificates, such as CELTA/DELTA or CerTESOL, and thereby save money, instead of taking IELTS or TOEFL.
Since, in theory, teaching certificates should indicate higher language ability than a foreign language certificate, don't you think this would be valid for graduate admission?
