B1 and B2 are both "Independent User" in the CEFR framework, and they are the two bands most German job ads are actually describing when they write "gute Deutschkenntnisse" without specifying a level. B1 handles routine work independently in plain sentences; B2 writes clearly and in detail across a wider range of subjects, and can follow an argument without help. The gap between them is where most professional German writing quality actually lives.
B1: Independent, on Familiar Ground
At B1, someone can produce simple connected text on topics that are familiar or of personal interest, and can handle most situations likely to arise in everyday work — describing a task, summarising a routine event, writing a straightforward request or update. The key word is independent: B1 does not need the fixed sentence patterns of A2, and can generate original text rather than adapt memorised phrases.
What B1 struggles with is range and nuance. German grammar adds a specific version of this struggle: subordinate-clause word order — where the verb moves to the end of the clause — and case endings both tend to simplify or slip under pressure, and a B1 sentence outside familiar territory often reads as slightly under-precise rather than actually wrong.
B2: Clear, Detailed, and Able to Argue a Point
B2 is a genuine step up: clear, detailed writing on a wide range of subjects, and the ability to explain a viewpoint, weighing the advantages and disadvantages of different options. That last part — structured argument rather than plain description — is the real marker of B2, and it is what most professional writing actually requires: an internal report that recommends something, an email that persuades, a summary that weighs options rather than just lists facts.
B2 also reads comfortably: notices, short articles, and workplace documents on familiar professional territory are accessible without needing every unfamiliar phrase explained. That reading fluency is what lets a B2 writer absorb source material fast enough to respond to it in kind.
Register Control Gets Harder, Not Easier
By B2, the du/Sie decision is no longer a fixed pattern learned by rote — it has to be judged correctly across a wider range of situations: a formal internal announcement, a casual message to a teammate, a request to someone senior. Getting the register right consistently, rather than only in the obvious cases, is one of the quieter markers that separates a solid B1 from a genuine B2.
Writing It Honestly on a CV
Naming the band directly — "Deutsch: CEFR B2" — sidesteps the ambiguity that phrases like "gute Deutschkenntnisse" or "fließend" carry, and it maps onto something a hiring reader can actually check against the role's real written demands.
It is also worth being specific about what the level covers: written German specifically, if that is what has been assessed, rather than letting a reader assume spoken ability is included. The German Proficiency test is explicit about this same boundary — it measures written German only, and a CV line should carry the same honesty.
Moving Toward C1
The step from B2 to C1 is mostly about flexibility and precision under less structured conditions: expressing ideas fluently without obviously searching for words, using German flexibly for social, academic and professional purposes, and producing well-structured, detailed text on complex subjects. It is less about new grammar and more about range holding up when the topic gets harder or the register shifts without warning.
The German Proficiency test scores reading, grammar, vocabulary and workplace usage separately across 40 questions in about 15 minutes, which shows specifically whether vocabulary range or structural precision is the more useful thing to work on next for a B1 or B2 result.
