One of the most challenging types of question on this forum is: Is such-and-such university recognised or accredited in this or that country?

The German state has a useful database that rates universities worldwide both by whether they are recognised in their own country, formally, and also whether they are comparable in quality to German universities. This "H+" level of compatibility is very useful, and it's used in deciding whether or not people quality under the EU Blue Card scheme.

I think Anabin is useful whether or not you are targetting Germany. It's a strong, independent assessment of quality. You can read more about the database and get a guide in English to using it, at:

Sadly the database works only in German, so if you don't know Germany you'll find the guide helpful.
