The qualification alone decides nothing. What is compared is the content: which subjects, how many hours, how much practice. That is why the subject and hours transcript is the most important paper in the pile — not the certificate with the seal.
§ 5 BQFG lists five mandatory items, and two of them appear on no certificate: the tabular list of your training and employment in German, and the declaration that you have not applied before. Those two are missing most often — with the result that the application is incomplete and the clock has not started.
And if the pile is incomplete, the road does not end. § 14 BQFG knows the case where evidence is missing through no fault of your own — after flight, war, or because a university no longer exists. Then the qualification is established another way: work sample, professional interview, examination, expert opinion. The route is longer, but it is provided for in the law and is not an act of grace.
