You’re paying €400/month. You’ve been at B1 for four months. Your teacher just explained the Dativ in English. Again. Sound familiar?
Not every German course is a scam. But plenty of them are a bad deal — and the language school industry has little interest in telling you that. So we will.
This is not a hit piece on language schools. Many schools in Germany are excellent. But if your course shows any of the five signs below, you are probably paying for the comfort of studying, not the results of it.
Let’s do the math. A standard intensive lesson runs 90 minutes. Your teacher speaks for roughly 40 minutes — explanations, corrections, new material. That leaves 50 minutes for students. Divide by 20 students, and each person gets 2.5 minutes of active speaking time per lesson.
Two and a half minutes. Per lesson.
Language acquisition research is clear: you need meaningful output, not just input. Sitting in a room while 19 other people struggle through the same exercise is input. It is not learning.
Schools with classes of 20+ students are optimizing for their own margins, not your progress. The economics are simple: more students per teacher means more revenue per lesson. You are subsidizing that equation.
What to look for instead: A maximum class size of 12, ideally 8-10. Schools like DeutschAkademie Stuttgart cap their groups at 12 and charge around €260/month. interDaF Leipzig runs 14-18 per class at a similar price — a meaningful difference in speaking time. Ask the school directly: “What is the maximum class size in my course?”
A well-structured intensive course moves students one full CEFR level in 8 to 12 weeks. That is approximately 200 contact hours — the standard benchmark. If you are doing 20 hours per week, that is 10 weeks. If you are doing 16 hours per week, that is 12-13 weeks.
If you have been at B1 for four months without progressing to B2, one of three things is happening: you are not attending consistently, you are not doing the homework, or the course is not working.
The first two are on you. The third one is on the school.
Signs the course is failing you: no formal progress assessments, no clear syllabus with level milestones, a teacher who moves at the pace of the slowest student rather than the median. These are structural problems that a new attitude on your part will not fix.
What to look for instead: Ask to see the curriculum. A serious school has a written syllabus that maps each week to specific CEFR competencies. They run placement tests and level assessments. At GLS Berlin, students move from A1 to B1 in approximately 14 weeks of intensive study. That is a concrete benchmark to hold other schools against.
A confused face should trigger more German — simpler German, slower German, German with gestures and examples. What it should not trigger is an automatic switch to English.
Teachers who switch to English are not being kind. They are avoiding the effort of explaining something differently. And every switch to English is 30 seconds you are not spending in the target language.
The “total immersion” principle is not a gimmick. Your brain switches into a different mode when you have no English safety net. You pay attention differently. You process differently. You remember differently. A classroom that constantly falls back on English trains you to rely on English — which is exactly what you are trying to stop doing.
There is a difference between strategic L1 use (explaining a truly untranslatable concept once) and habitual English as a default. If your teacher is in the habit of switching languages the moment anyone hesitates, that classroom is not an immersion environment. It is an English classroom with German vocabulary.
What to look for instead: Ask prospective schools about their language-of-instruction policy. Do they teach in German from day one, even at A1? The answer tells you a lot about their pedagogical standards. The best schools hold German-only from the first lesson, with visual aids and context to compensate for the lack of L1 support.
Here is an uncomfortable truth: a school that does not prepare you for a recognized exam is teaching you “German” without a measurable outcome.
What does that mean in practice? You attend for three months. You feel like your German is better. But you have no telc certificate, no Goethe-Zertifikat, no TestDaF result. You cannot prove anything to a university, an employer, or a Visa authority. Your progress lives entirely in your own perception.
That is not enough.
Recognized exams — telc Deutsch B1, telc Deutsch B2, Goethe-Zertifikat, TestDaF, DSH — are the proof of work in German language learning. They are internationally recognized. They unlock university admission, visa extensions, and professional opportunities. A school that does not structure its courses around them is selling you comfort, not credentials.
Think of it like a gym without a scale. You might be getting fitter. But if nobody is measuring anything, how would you know?
What to look for instead: Check whether the school is an official telc exam center, a TestDaF center, or a Goethe-Zertifikat partner. Schools with these accreditations have exam dates on-site and courses specifically designed to meet exam standards. You can find which schools on our search page hold which accreditations.
telc exam center. TestDaF center. BAMF approval. AZAV certification. Goethe-Zertifikat partner.
If a school has none of these, ask why.
Accreditations are not free. They require audits, standard-compliant facilities, qualified teachers, and documented processes. Schools that invest in accreditation are schools that have submitted to external quality checks. Schools that skip accreditation have not.
This does not automatically make an unaccredited school bad. Some are excellent. But their quality is self-reported. Nobody is checking their class sizes, their teacher qualifications, or their exam pass rates. You are taking their word for it.
If you are studying German for a functional reason — a visa, a job, a university place — accreditation is not optional. BAMF-approved courses are required for integration course funding. AZAV certification is required to use a Bildungsgutschein (education voucher) from the Bundesagentur für Arbeit. A school without AZAV certification cannot accept your voucher, no matter how good it is.
What to look for instead: Look for at least one of: telc exam center, BAMF approval, or AZAV certification. You can verify these directly on the telc website, the BAMF portal, and the AZAV register. Do not take the school’s website as proof — cross-check independently.
Here is the honest counterpart to everything above.
Plenty of German courses are excellent. A good intensive course is still the fastest way to reach B2. No app, no podcast, no YouTube channel gets you there in 12 weeks. The structure, the feedback, the speaking practice, the exam preparation — combined, they work. The research backs this up.
The courses that are worth every euro share the following traits: small classes (under 12), a clear written curriculum, exam-oriented teaching, at least one recognized accreditation, and teachers who push you to speak German from day one.
Those schools exist. You just need to know how to find them.
Answer yes or no:
8-10 yes: Your course is working. Stay.
5-7 yes: Some structural problems. Raise them with the school directly.
Under 5 yes: Your money is probably going somewhere better — into a different school.
The research consensus is 8-12 students per class. Under 8 and costs go up significantly. Over 12 and individual speaking time drops below what’s needed for meaningful progress. If a school advertises classes of “up to 15” or “up to 20,” that is a sign they prioritize enrollment over learning outcomes.
In a proper intensive course (20 hours/week), 10-14 weeks is realistic. The CEFR recommends approximately 200 classroom hours per level. If you have been at B1 for more than 4 months in an intensive course, something is wrong — either with your attendance, your study habits, or the course structure.
BAMF approval means the Bundesamt für Migration und Flüchtlinge has approved the school to run integration courses and language courses under the Aufenthaltsgesetz (Immigration Act). AZAV certification means the Bundesagentur für Arbeit recognizes the school — which allows students to redeem a Bildungsgutschein (education voucher). Both require external audits and ongoing compliance. They are different approvals for different purposes.
That depends on the school’s contract terms and German consumer law. Most language schools include a cancellation clause — typically 4 weeks’ notice. If the school is not delivering what was promised in writing (e.g., a specific class size or exam preparation), you may have grounds for a partial refund under §313 BGB (frustration of purpose). Document everything in writing.
No. Some private language schools without formal accreditation are genuinely good. But accreditation is the only external quality signal you have before enrolling. Without it, you are relying entirely on reviews, word of mouth, and trial and error. If you are studying for a specific exam or visa requirement, accreditation is non-negotiable.
Take a preparatory course at an accredited school, then sit a telc exam. telc B1 costs around €150 for the exam itself. Add a 6-week intensive prep course at a mid-range school (around €400-500) and you have a recognized B1 certificate for under €700 total. Self-study plus one exam sitting is cheaper but statistically less reliable — exam pass rates are significantly higher for students who attend structured preparation courses.
Reviews measure satisfaction, not outcomes. Students often rate their experience highly even when progress is slow — because the social environment is pleasant, the teacher is nice, or the alternative feels daunting. If you are not progressing at the rate described in Sign 2 above, look at the structural data, not just the sentiment.
