Advice on Teaching English in Poland [709]
Agreed. CELTA, DELTA, TESOL and TEFL are major components of the alphabet soup of the ESL industry.
They all work for different people. I chose the TEFL and haven't had a problem finding work when I wanted it. II am well aware that there are a couple of places which use it as a qualifier but don't think I have ever cared about working at a place like that for one reason or another. In a similar fashion, I have seen ads specifying age, sex, nationality (not for legal reasons) and other qualifiers as conditions of employment and consideration.
You can work with any of them in most situations although it's always possible you'll miss a screening due to others in the stack having one or another preferred qualifications in the eye of the hiring manager or owner.
As long as there was some student contact (usually 10 hours or more) and 100+ hours of classroom instruction that should get you into most applicant pools.
All that said, I'm thinking about a CELTA this summer. The paper is irrelevant but I enjoy meeting a new group of teachers and trainers. If I was in a place where TEFL classes were common (like Prague) then doing another TEFL would be fine as well. If I was 15 years younger I would go back and complete another BA in Secondary Education with an emphasis in Social Studies and combine it with my other education then work the International Schools circuit.
So, a good TEFL or CELTA work fine. The MA-TESOL and DELTA are great for those making a life-long career out of this as well. Other combinations work based on the individual.
As for Korea, the base qualification I am aware of are a valid BA. I am sure there are some schools which have requirements but if you want to teach kids you can work in Asian public schools easily enough without anything more. CELTA and TEFL classes are taught in Korea and in Japan if you decide you want to upgrade your skills and add some paper to your CV.
Good luck.
