telc and OSD Prep: Format Differences and How to Practise Each

Here is the trap. You book a German exam because the Ausländerbehörde, an employer, or a university wants a B1 or B2 certificate. You prepare with generic textbook drills. Then on exam day the format surprises you: a paired speaking task you never rehearsed, or a grammar gap-fill section nobody mentioned. This guide explains how telc and ÖSD differ and how to practise for each.

telc vs ÖSD: How the Two Exams Are Actually Built

When I first had to prove my German, I assumed every certificate tested the same thing in the same way. B1 is B1, right? Partly. The Common European Framework sets the level, so a telc B1 and an ÖSD B1 measure roughly the same ability. Each provider then builds its own exam around that level. The task types, the order of sections, the speaking set-up and the passing rules all differ. Those differences decide how you should spend your limited study hours.

Both certificates are widely used in Germany. telc is everywhere because so many Volkshochschulen and integration course providers host it, from the Münchner Volkshochschule to small adult education centres in Saxony. ÖSD is the Austrian Sprachdiplom. It is offered at a network of language schools across Germany, and many expats in Munich, Stuttgart and Frankfurt sit it because the dates or the modular format suit them. Before you pick either one, ask the authority or employer exactly which certificates it accepts. If you are preparing for naturalisation, see How to Prove German Language Skills for Citizenship (B1).

The Written Side Compared

The telc written exam runs as one sitting with distinct parts: reading, listening, a section called Sprachbausteine, and writing. Sprachbausteine is the part that catches people. It is a set of gap-fill texts testing grammar and vocabulary in context. You pick the right preposition, connector, verb form or word from a list. The Goethe-style exams have no direct equivalent, so learners who prepared with Goethe material are often blindsided by it.

The telc writing task at B1 is typically a letter or email responding to a situation. You get several guiding points (Leitpunkte), and you must address them in your answer. The examiners care whether you covered the points, organised your text, and used the right register for the recipient.

ÖSD writing at B1 is built differently. You face several shorter tasks across different registers: something informal to a friend, an opinion-style text, and a more formal message. Instead of polishing one letter, you have to switch tone quickly between tasks. ÖSD listening and reading are also designed with the whole German-speaking world in mind. You may hear Austrian voices, references to Austrian everyday life, or vocabulary that sounds slightly unfamiliar if you have only ever lived in Hamburg.

The Oral Side Compared

This is where the exams feel most different on the day, and where most preparation goes wrong.

The telc B1 oral exam is usually done in pairs. You sit with another candidate in front of two examiners after a short preparation period. The structure moves through three stages:

1. A getting-to-know-you conversation with your partner.
2. A discussion of a topic, often prompted by a short text or statement.
3. Planning something together, such as a party, a trip or a farewell gift.

You are assessed partly on how well you interact. Interrupting politely, agreeing, disagreeing and suggesting alternatives all count.

The ÖSD Zertifikat B1 speaking test is also typically done in pairs, but the weight shifts. You plan something together with your partner, as in telc. You also give a short structured presentation on a topic from prepared slides or prompts, then answer questions and respond to your partner’s presentation. So ÖSD rewards a confident, structured monologue more than telc does. telc rewards spontaneous back-and-forth across the whole test.

Scoring, Modules and Retakes

Both exams split the result into a written part and an oral part. You generally need to reach the pass mark in each. A brilliant written result will not rescue a weak speaking performance.

ÖSD goes further with its modular design. At B1, reading, listening, writing and speaking are separate modules. You can take them together or individually, and if you fail one you can usually retake just that module rather than the whole exam. For working professionals that is a real advantage. Strong readers who freeze when speaking can bank three modules and focus everything on the fourth.

telc has traditionally been sat as a complete exam, although the written and oral results are reported separately. Always check the current rules with the specific test centre. Rules on partial retakes and validity can vary by exam variant and centre.

How to Practise for telc: Sprachbausteine, Letters and the Paired Oral

I have watched friends who chat happily in German at the Späti fail the telc oral. They had never practised the specific moves the exam asks for. I have also watched shy friends pass comfortably because they drilled those moves until they were automatic. telc preparation is about rehearsing patterns, not becoming a different person.

Training for the Sprachbausteine Section

Sprachbausteine rewards precision. You are not choosing between plausible ideas. You are choosing between “obwohl” and “trotzdem”, “auf” and “an”, “würde” and “wurde”. Generic conversation lessons will not fix this, and neither will vocabulary apps on their own.

The most efficient approach I have found is a three-step loop:

1. Do a timed Sprachbausteine set from an official telc model test.
2. Mark it, and write down every mistake by category: case after prepositions, connectors and word order, verb tenses, fixed expressions.
3. Bring that error list to a tutor and have them build short targeted exercises around your weakest category.

This is where a tutor on iTalki earns their fee. A good one will not simply explain the rule again. They will give you ten fresh sentences built around your exact weak point, then ask you to say why each answer is right. Saying the reason out loud is what makes it stick. If you hit the same mistakes week after week, it is worth reading Breaking the B1 Plateau: Why Grammar Study Stalls and What Speaking Fixes, because Sprachbausteine errors are often a symptom of grammar you know on paper but never use when speaking.

Writing the telc Letter Without Losing Points

The telc letter is predictable, and predictability is your friend. Build yourself a skeleton you can reuse:

1. An opening suited to the register: formal for a landlord or company, informal for a friend.
2. A sentence stating why you are writing.
3. One short paragraph for each guiding point, in the order given.
4. A closing sentence that asks for a reply or confirms next steps.
5. A sign-off that matches the opening.

The most common way people lose marks is by skipping a guiding point. Another is spending all their effort on one point and giving a half sentence to the rest. Practise ticking each point off as you write.

Hypothetical scenario: Priya, a nurse in Düsseldorf, gets a prompt about writing to her course organiser because she missed a class. The four points are: why she missed it, what she wants to catch up on, a question about the next session, and an apology. Her first draft is lovely German but spends three paragraphs on why she was ill. A tutor reviewing it would cut that down, move the apology near the top, and add a clear question at the end. That edit alone could lift the score significantly. Sending one or two letters a week to a tutor for written corrections is one of the highest-return habits you can build.

Rehearsing the Paired Oral Exam

The telc oral is a performance with a script you know in advance. You just do not know the topic. Rehearse each stage separately:

1. Introduction stage. Prepare a flexible set of things to say about your job, family, hobbies, how long you have lived in Germany and why you are learning German. Practise asking your partner the same questions back. Interaction counts.
2. Topic discussion stage. Practise giving an opinion, a reason and a personal example in a natural chain. Then practise reacting to someone else’s opinion with phrases like “Da bin ich anderer Meinung” or “Das sehe ich ähnlich, aber…”.
3. Planning stage. This is pure negotiation. Rehearse making suggestions, rejecting them politely, offering alternatives and summarising the agreed plan at the end.

Your tutor can play your exam partner, including a difficult partner who talks too much or barely speaks. On the day you do not choose who you are paired with, and a talkative partner can push you into silence if you have never practised cutting in politely.

How to Practise for ÖSD: Modules, Accents and the Presentation

ÖSD preparation feels different because the exam asks you to be adaptable. You may need to understand an Austrian speaker in the listening section, switch writing registers mid-exam, and then hold the floor alone during your presentation. Each of these can be trained.

Getting Comfortable With Austrian and Regional German

The first time I heard an Austrian news clip after a year in northern Germany, I caught maybe two-thirds of it. Nothing was wrong with the grammar. The vowels, the rhythm and a handful of everyday words were just unfamiliar. “Jänner” instead of “Januar”, “Paradeiser” for tomatoes, “heuer” for this year. ÖSD listening does not try to trick you, but it does reflect that German is spoken across several countries.

The fix is exposure plus guided decoding:

1. Listen to short Austrian clips: radio segments, interviews, everyday dialogues.
2. Write down every word or phrase you did not catch.
3. Go through them with a tutor who knows the variety and can say it in standard German beside the Austrian version.

On iTalki you can filter tutors by where they are from. Booking a few sessions with an Austrian tutor before an ÖSD sitting is a smart move even if you will spend your life in Germany. For more on when that makes sense, see Austrian and Swiss German Tutors: When They Make Sense for a Germany Move.

Practising Multiple Writing Registers

Because ÖSD gives you several shorter writing tasks, the skill being tested is switching. You need to move from “Hallo Jonas, wie geht’s?” to “Sehr geehrte Damen und Herren” in a few minutes without carrying informal phrasing into the formal text.

A practical drill:

1. Ask your tutor for three prompts at once: one informal, one opinion-based, one formal.
2. Write all three in a single timed session.
3. Have the tutor mark register errors separately from grammar errors.

You will quickly see whether your problem is “my German is wrong” or “my German is fine but sounds wrong for this reader”. Those need different fixes. Register errors are fixed with fixed phrases and templates. Grammar errors take more structural work.

Opinion texts deserve extra attention. Many learners can describe things at B1 but struggle to argue a position with linked reasons. Collect a small toolkit of connectors such as “einerseits… andererseits”, “deshalb”, “außerdem”, “im Gegensatz dazu”, and practise using them in short paragraphs until they come without thinking.

Building a Strong ÖSD Presentation

The presentation section is where ÖSD rewards preparation most generously. The topics vary, but the structure you are expected to follow is predictable. You introduce the topic, describe the situation in your home country, discuss advantages and disadvantages, give your own opinion, and close. Learn that structure once and reuse it for any topic.

Here is a simple way to prepare it with a tutor:

1. Agree on a bank of about ten everyday topics: working from home, living in a big city versus the countryside, online shopping, learning languages, sports and health.
2. For each topic, deliver a short presentation using the fixed structure, without notes the second time round.
3. Have your tutor interrupt with the kind of follow-up questions an examiner or partner might ask.
4. Swap roles: the tutor presents and you ask questions, because responding to your partner’s presentation is part of the test too.

Hypothetical scenario: Tomás, a software developer in Stuttgart, can talk about remote work for twenty minutes in English but stalls in German after the second sentence. After four sessions running the fixed structure on different topics, he no longer has to think about what comes next. He only has to think about the content. That frees up enough mental space to speak more naturally and fix his own errors mid-sentence. This is exactly the kind of targeted rehearsal that one-to-one lessons on iTalki are suited for, and that group classes rarely have time for.

Building Your Exam Prep Plan With an iTalki Tutor

Self-study gets you a long way on reading and listening. Model tests, podcasts and graded readers are excellent and cheap. Writing and speaking are different. You cannot mark your own letter for register mistakes you do not know you are making, and you cannot rehearse a paired oral exam alone in your kitchen. That gap is why I recommend iTalki as the core of exam preparation for both telc and ÖSD.

Choosing the Right Tutor for Your Exam

Not every German tutor is an exam coach. When you browse iTalki, look for tutors who mention telc or ÖSD by name in their profile, not just “exam preparation” in general. During a trial lesson, ask direct questions:

1. Which exam formats have you prepared students for, and at which levels?
2. Do you use official model tests in lessons?
3. How do you give feedback on writing, during the lesson or as written corrections afterwards?
4. Can you play the exam partner and the examiner in a mock oral exam?

If the answers are vague, keep looking. Our guide How to Choose a German Tutor on iTalki: Screening Questions and Red Flags covers more warning signs. For help deciding between a casual conversation partner and a qualified teacher at exam stage, see Community Tutor vs Professional Teacher on iTalki: Which for Your Level?. For telc Sprachbausteine and ÖSD writing marks, a professional teacher is usually worth it. For extra speaking time in the final weeks, a community tutor can be a good, cheaper top-up.

On cost: tutors on iTalki set their own rates, so prices vary widely by experience and specialisation. Trial lessons are typically offered at a reduced rate, and many tutors sell lesson packages that bring the price per session down. Check each tutor’s profile for their current pricing. Before you buy, it is worth reading iTalki Packages vs Single Lessons: How to Buy Without Wasting Credits so you do not lock credits in with a tutor you have not fully tested.

Structuring Lessons by Exam Section

The biggest mistake I see is booking “German lessons” when what you actually need is exam lessons. Tell your tutor which exam you are sitting and when. Then split your sessions by purpose. Here is a practical split for the weeks before the exam:

How many sessions you need depends on your starting level and how close you already are to the target. If you are unsure, Budgeting Tutor Hours for B1 Certification: How Many Lessons You Really Need helps you estimate realistically. On spacing, How Often Should You Book German Lessons? Frequency vs Progress explains why two or three shorter sessions a week usually beat one long weekly block before an exam.

The Final Weeks Before Exam Day

The last stretch is not the time for new grammar. It is the time for rehearsal under exam conditions. Here is the routine I would follow, and the one that worked for me:

1. Sit at least two full written model tests at home under timed conditions, without pausing or looking anything up.
2. Book a full mock oral exam with your tutor at the same time of day as your real exam if possible.
3. Ask your tutor to switch to examiner mode for one session: no corrections during the task, only a debrief at the end, the way a real examiner behaves.
4. Review your error list one last time and pick the three mistakes you are most likely to make under pressure. Write them on a card and read it the morning of the exam.
5. In the final days, keep the lessons light: short speaking warm-ups to stay fluent, not heavy correction sessions that shake your confidence.

One more practical tip that sounds obvious but saves people every exam season: visit or at least look up your test centre in advance. A Volkshochschule exam room in a large city building can be hard to find on a busy Saturday morning. Arriving flustered costs you focus in the first section, and the first section for telc is often reading, where calm concentration matters most.

If your exam is part of a longer goal, such as moving from B1 towards B2 for professional recognition, keep your tutor relationship going after the result arrives. The same tutor who knows your error patterns can carry you to the next level much faster than starting over. If you are weighing a Goethe exam instead, the same lesson planning principles apply; see Goethe Exam Prep With a Tutor: Choosing Your Level and Timeline.

Preparing for telc or ÖSD is far less intimidating once you see the exam as a set of predictable tasks rather than a vague test of “your German”. Pick the format that suits your strengths. Get the official model tests. Then book a trial lesson on iTalki with a tutor who knows your exam by name and can rehearse every section with you until exam day feels like a repeat of something you have already done.
