The satisfaction scale (Zufriedenheitsskala)
| Grade | German phrase | Means |
|---|---|---|
| 1 | “stets zu unserer vollsten Zufriedenheit” | very good (sehr gut) |
| 2 | “stets zu unserer vollen Zufriedenheit” | good (gut) |
| 3 | “zu unserer vollen Zufriedenheit” | satisfactory (befriedigend) |
| 4 | “zu unserer Zufriedenheit” | sufficient / adequate (ausreichend) |
| 5 | “im Großen und Ganzen zu unserer Zufriedenheit” | poor / deficient (mangelhaft) |
What is an Arbeitszeugnis?
An Arbeitszeugnis is a formal written reference German employers must provide when your employment ends, and usually when you ask for one mid-job. There are two kinds. A simple reference (einfaches Zeugnis) confirms only your role and dates. A qualified reference (qualifiziertes Zeugnis) also assesses your performance and conduct, and it's the one that matters for your career. Almost every German recruiter expects to see it, and many won't shortlist a candidate who can't produce one.
At first glance a qualified Arbeitszeugnis reads like unbroken praise. Every sentence is polite and appreciative. That warmth is the trap: the document is written in a coded professional language, Zeugnissprache, where the real evaluation hides in small differences of wording. Two references can look near-identical to an untrained eye yet award grades that are worlds apart. Reading the code is the only way to know what your former employer actually told the market about you.
For expats the gap is especially dangerous. If German isn't your first language, a reference can read like a heartfelt thank-you letter when it's really a lukewarm or even negative verdict. Many newcomers file their Zeugnis away proudly, never realising it carries a below-average grade that quietly weakens every future application. The document also follows a fixed structure: tasks, skills, performance, conduct, then the closing lines. A marker can hide in any of those blocks.
Why the secret code exists (the law)
The coded language comes straight out of German employment law. Your right to a written reference is anchored in § 109 of the Gewerbeordnung (GewO), Germany's trade regulation act, which entitles every departing employee to a qualified reference on request. That reference must satisfy two duties that pull against each other. It must be truthful (wahr), so an employer can't invent achievements or bury serious problems. And it must be benevolent (wohlwollend), worded so it doesn't needlessly damage the employee's future prospects. The Federal Labour Court (Bundesarbeitsgericht) has confirmed both principles repeatedly, and neither may cancel the other out.
Open criticism would breach the duty of benevolence, so an employer can't simply write that someone was slow, difficult, or unreliable. Over decades, a shared vocabulary of euphemisms grew up instead, one that keeps employers factually honest while signalling a negative verdict to anyone who knows the system. A phrase that sounds generous to a foreigner can be a quiet warning to a German HR manager. The law even names the problem: § 109 (2) GewO bans formulations that secretly mark an employee in an unfair way. But the established grading phrases count as common knowledge in Germany, so they stay fully legal and widely used.
The result is a document written for two audiences at once. To you, it reads as a friendly farewell. To the next recruiter, it reads as a graded transcript. The gap between those two readings is where careers are quietly made or held back.
The satisfaction scale: how grades are hidden
The heart of the code is a single sentence about how satisfied the employer was with your work. German school grades run from 1 (very good) to 6 (unsatisfactory), and the reference mirrors that scale through tiny shifts in wording. Two levers do the work: how strong the satisfaction word is (volle, vollste), and whether stets, meaning always or consistently, reinforces it.
The ladder runs like this. "Stets zu unserer vollsten Zufriedenheit" (always to our fullest satisfaction) is grade 1, very good. "Stets zu unserer vollen Zufriedenheit" (always to our full satisfaction) is grade 2, good. "Zu unserer vollen Zufriedenheit" (to our full satisfaction), with no always, drops to grade 3, satisfactory. Plain "zu unserer Zufriedenheit" (to our satisfaction) is grade 4, a below-average pass. And "im Großen und Ganzen zu unserer Zufriedenheit" (on the whole to our satisfaction) is grade 5, a clear fail dressed up as courtesy.
So a single missing word can move you a whole grade. "Fullest" versus "full" is the line between top marks and merely good, and "stets" present or absent shifts you again. That's why you read a reference word by word instead of skimming it for its friendly mood.
Common coded phrases and red flags
Beyond the satisfaction sentence, several stock phrases carry hidden meaning. The most notorious is "Er hat sich stets bemüht" (he always made an effort). Effort language is a polite way of saying the results weren't there, and it's widely read as a failing grade. Praise for sociability ("Geselligkeit") or for boosting the workplace atmosphere works the same way: it can hint at drinking or socialising instead of working, especially when it stands in for praise of actual output.
Watch the order and the omissions too. If a reference lavishes detail on minor duties but sums up your core responsibilities in one flat line, that imbalance is deliberate. Praising loyalty and honesty in an ordinary employee can imply those qualities were in doubt. And any note that someone met expectations "in the main" or "for the most part" is code for falling short.
The closing paragraph is its own red-flag zone. A strong reference thanks the employee, expresses regret at their leaving, and wishes them well for the future, personally and professionally. If your Zeugnis ends abruptly on the bare fact that you left, with no thanks and no good wishes, that silence is itself a negative signal. In Zeugnissprache, what's left out speaks as loudly as what's written.
What to do if your Zeugnis is bad
First, decode it calmly, sentence by sentence, and confirm what grade the wording actually gives you before you react. A reference that feels underwhelming may only be a grade 3, which is legally normal; one that reads as polite may hide a 5. Knowing exactly where you stand tells you whether it's worth challenging.
You have a legal right to a reference that is both truthful and benevolent, and German case law treats an average grade (grade 3, satisfactory) as the default an employer must justify moving away from. If your reference sits below average, the employer usually has to prove you deserved worse; if you claim you deserve better than average, the burden shifts to you. In practice, a below-average Zeugnis full of effort-phrases and missing good wishes is often correctable.
Ask your former employer in writing for a corrected reference (Berichtigung), naming the specific phrases and the grade you think is fair. Many disputes end here, because employers know the code too. If they refuse and the stakes are high, an employment lawyer or your works council can help, and you can take the claim to a labour court (Arbeitsgericht). Limitation periods apply, so don't wait indefinitely. And never quietly accept wording you don't understand: that document follows you to every future interview.

Frequently asked questions
Is my Arbeitszeugnis legally required to be positive?▼
It must be both truthful and benevolent (wohlwollend), worded so it doesn't needlessly harm your future prospects. That's not the same as positive. An employer can legally give you a below-average grade if the wording is accurate, but they can't invent faults or push honest criticism beyond what the facts justify.
What does 'stets zu unserer vollsten Zufriedenheit' mean?▼
It translates as 'always to our fullest satisfaction' and is the top grade, a 1 (very good) in the German school system. Two signals make it grade 1: the superlative 'vollsten' (fullest) and the reinforcing word 'stets' (always). Drop either one and the grade falls.
What grade is 'zu unserer Zufriedenheit'?▼
Plain 'zu unserer Zufriedenheit' (to our satisfaction), with no 'stets' and no 'vollen' or 'vollsten', is grade 4, a below-average pass. It sounds courteous but signals that your performance was only just acceptable. Put 'im Großen und Ganzen' in front and it sinks to grade 5, effectively a fail.
Does the closing paragraph matter?▼
Yes, it's one of the most revealing parts. A good closing thanks you for your work, expresses regret that you're leaving, and wishes you well both personally and professionally. If those thanks and good wishes are missing, that conspicuous omission reads as a deliberate negative signal, even when every earlier sentence sounds friendly.
Can I challenge a bad Arbeitszeugnis?▼
Yes. Request a corrected reference (Berichtigung) in writing, naming the specific phrases and the grade you consider fair. German courts generally treat an average grade as the baseline, so a below-average reference often puts the burden on the employer to justify it. If they refuse, a works council, an employment lawyer, or the labour court can help, but mind the applicable time limits.
