The international schools I have worked in have frowned on this as side work.

Understand that MYP courses are going to be significantly more work than DP courses in a school that doesn't already have materials created. The DP subject guide tells you exactly what to teach, and there's less of an emphasis on creative lessons. Motivation is easier. You prepare students for the test. With MYP, you'll have more projects that use different grading criteria and you have to differentiate a lot more. The MYP is a harder to learn and requires a lot more time. Be prepared to work far beyond the required hours, especially if you have multiple preps.

I did my M.Ed Admin internship through an American public university at the Southeast Asian international school I worked at. A couple of suggestions: 1. Make sure your current principal is on board with you doing the internship. I needed mine to sign off on a lot of papers, and while he was willing to do it, it was a pain and since my principal didn't share my nationality, he wasn't familiar with the processes that I was going through. If your principal isn't willing to sign off on everything, you can't complete the internship. 2. Don't change jobs during the program. You'll end up doing a lot of extra work for the school, and it puts you in a good light. Completing the program puts you in a good position to get promoted at your current school. At least that was my experience. Good luck.

That's basically what's happened in New Orleans.

These are my observations as a teacher at a low-paying for-profit in Southeast Asia.

The only goal of the school is to make profit, and education is secondary at all times.

White, western faces look good and are the ideal. If the school can get these at a low price, great. If the school has a few to some teachers like this, then parents are less likely to notice as the school hires people without teaching licenses, and more eastern Europeans, middle easterners, and south Americans. People who are happy with an American minimum wage 18-22k per year type of salary. I'm cheap labor, and I'm treated as such.

Can it be a career? If you can get into a better school. But many people can't, and they still stay international. Most good teachers, or teachers who think they are good, either get into a good school or return home. However, in many ways you can live more comfortably and save more making 22k in Southeast Asia than you can on a normal 50-60k teacher's salary in the US, and this is why for some it stays a career, even if they can't get into better school. And one so far unstated advantage for Americans, is that with an income based student loan repayment plan, and the fact that your entire income is untaxed because of the foreign earned income exclusion, you don't have to make student loan payments or ever pay your student loans back as long as you stay overseas.

Retirement wise, the perspective is somewhat different. If you've been in Southeast Asia, then you're probably comfortable retiring with 300-500k, instead of the 1-2 million that many financial resources say you need to retire comfortably. If you work from 45-65 and put away 10k a year during that time, which is still possible even making only 22k a year in SE Asia, then you can retire comfortably in this part of the world if not richly.

Something to consider is that being able to pass the Praxis HS Math certification test isn't the same as being able to actually teach upper level math. For example, I passed the test, because I can beat any math multiple choice test. But I have nowhere near the math knowledge to teach IBDP Math SL or HL, or AP Calculus, and that's what most international schools who have openings are going to want you to teach.
