Hi Heliotrope, Sorry for asking such basic questions, I am literally just getting started doing this, I didn't know what questions to ask. It's all new for me. Will use the search functions as you instructed!

Hi Sid, Thanks for the information, that is really helpful! I am really new to this, so I was not aware that there such a thing as ISS. It sounds like ISS schools are on the whole significantly better than non-ISS ones, is that right?
As for my situation, I am a US citizen, but am living abroad already, so getting a state certificate is possible, but definitely not convenient, as it means I have to go back to the US and live there for around a year, which I don't really want to do, but can do. Do I have any other options, for example somehow getting a state certificate while abroad, or getting some other certificate?
Thanks again for your attention and help!

Also- are online certifications from accredited organizations accepted?

Hi everyone,
I think I should introduce myself first, since this is my first ever post. I am from the US originally, and have fourteen years of experience teaching ESL, mostly to adults but also some to teens. In university, I studied history, as well as German as a second language. I currently work online teaching ESL, and am exploring what it would take to teach in international schools.
One big question I have is what certificates are required to teach. It seems like there are several different currciula out there, the most popular ones being US K-12 curriculum, British, and IB. Are there big differences in pay between these different programs? Is one of them more popular than the others?
Also, I know that to get a job in an ISS, I need to have a Master's in Education, a US state teaching license, or possibly some other options. Which of these certificates is best to get to teach the different curricula I mentioned above? Do most schools have hard and fast requirements about which certificate you need, or is there some flexibility?
Thanks for any help you all can provide!
Tim
