How difficult is the DTZ? Difficulty, structure, and typical mistakes

V-IZ Editorial 3 min read

How difficult is the DTZ really?

For most test takers, the DTZ is manageable, but it’s not automatic. In practice, a DTZ certificate may show B1, A2 or an insufficient result. However, for citizenship, you typically need the B1 result on your language certificate. How difficult the test feels depends heavily on how much you practiced beforehand, especially speaking and writing.

If you attended the integration course regularly and completed the practice sets, B1 is a realistic goal. The difficulty usually doesn’t come from the knowledge itself, but from stress, time pressure, and avoidable mistakes.

How is the DTZ structured?

The DTZ has a written and an oral part. In total, four language skills are tested.

Written part (approx. 100 minutes)

  1. Listening (approx. 25 minutes): You hear announcements, conversations, and messages and answer questions about them.
  2. Reading (approx. 45 minutes): You read short texts like advertisements, letters, or signs and mark the correct answer.
  3. Writing (approx. 30 minutes): You write a short message or letter, for example an apology or an inquiry.

Oral part (approx. 15 minutes)

Speaking is usually a paired exam with another test taker. You introduce yourself, talk about a topic, and plan something together, for example a celebration.

How is the DTZ graded?

In total, you can reach 100 points. The points are distributed across the four skills. What matters is not just the overall point total, but also which parts you achieve B1 level in.

In order to have B1 on your certificate, you must achieve B1 level in at least two skills. One of them must be speaking. So speaking is the most important part. If you’re strong here, you’re already halfway to B1.

If you don’t manage that, you’ll receive your certificate at level A2. It’s not a disaster, but it’s usually not sufficient for citizenship.

The most common mistakes on the DTZ

We see the same mistakes repeatedly in practice. Most of them are easy to avoid.

1. Not practicing speaking enough

2. Using the wrong letter format

When writing, content is not the only thing that counts, but also form. Never forget:

  • the greeting (“Dear Sir or Madam” or “Dear Mrs. …”)
  • all the points given in the task (it’s often four)
  • the appropriate closing at the end (“Sincerely” or “Kind regards”)

If you forget a point or choose the wrong greeting, you’ll lose valuable points.

3. Poor time management while reading

45 minutes sounds like a lot, but it’s tight. Don’t get stuck on a difficult task too long. Do the easy ones first and come back later. Don’t leave any gaps blank at the end, guess instead.

4. Trying to say too much at once

When speaking, you don’t need to build complicated sentences. Simple, clear, and correct sentences earn more points than long sentences with many mistakes. Speak calmly and in complete sentences.

5. Underestimating the oral part

Because speaking is mandatory for the overall B1 result, it’s the most important part. Yet many people prepare for it the least. Set aside dedicated time for it.

What does the DTZ cost and can you retake it?

If you have authorization for an integration course, the DTZ is usually free, including a free retake after a follow-up course. As a self-paying test taker without authorization, you’ll pay a fee depending on your test center. You can retake the test if the result is not sufficient. Ask your course provider or test center for the exact conditions.

Frequently Asked Questions

Can you fail the DTZ?

Not in the classical sense. In practice, a DTZ certificate may show B1, A2 or an insufficient result. Only those with very few points fail to achieve any level.

What level do I need on the DTZ for citizenship?

For citizenship, you typically need the B1 result in your language proficiency certification. Level A2 is usually not sufficient. If in doubt, ask your competent authority.

How many points do I need for B1 on the DTZ?

In total, there are 100 points. To receive the overall result B1, you must achieve B1 level in at least two language skills, and one of them must be speaking. So the overall point total alone is not what counts.

Can I retake the DTZ?

Yes. With integration course authorization, free retakes are usually possible after a follow-up course. Self-paying test takers pay a fee per attempt. Your test center will provide the exact rules.

Which part of the DTZ is most important?

Speaking. To get the overall B1 result, you must reach B1 in the oral part. That's why you should practice free speaking especially well.

How long does the DTZ take?

The written part (listening, reading, writing) takes about 100 minutes in total. The oral part takes around 15 minutes and is usually a paired exam.
