Below is a list submitted by the German representative of the Central Agency for German Schools Abroad. I checked all the websites and many are in German but we hope that the list is still helpful to you.
I added the website below and I would encourage you to start with this site (you can select your language).
Here is an overview of German language examinations, presented by the University of Munich. You can switch to English. In the German version, you can scroll down to the very bottom and find a very useful overview of a multitude of ways to take an examination to proof your German proficiency. There are tests by the German universities -DSH, by the Goethe Institut, by the TestDaF centers, and of course, the DSD examinations that the German schools abroad offer.
