Dear @marlometaj,
Welcome to the Wefugees Community and thank you for your question.
During my research, I noticed that sources provide different information about this. Some websites say that the B1-level must be proven. However, on the website of the city of Nuremberg in Bavaria, for example, it is stated that the training company can alternatively confirm that the language skills are sufficient for the training/Ausbildung.
It seems to be the safest option to make the test, but in the meantime you could sumbit a confirmation from your future employer.
Do you agree dear @mbeon-fardeen?
I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
Meike
