Although I don’t have the answer to your questions, I thought you would be interested in knowing that the requirements to teach in Europe are very different than the United States.
It might be a good idea to visit www.ereps.eu.
It’s going to be pretty difficult to secure work if you don’t prove your credentials and abilities with the governing bodies.
The only way that I am able to teach across the Europen Union is that my credentials have been recognized by EREPS in the UK and EREPS Italy.
Hope this information is of help to you.
I am German (born in Berlin 🙂 and did some searches in German with no result at all.
As Joanne mentioned, make sure you know all the rules for employment when in Germany. Since your husband is the one employed, his company may help you identify what you are or are not allowed to do. German laws are known for some rigidity.
R.I.P.P.E.D or not: I hope you will enjoy your stay in Germany. Viel Vergn├╝gen!
