First impressions matter – this is especially true for the TestDaF writing section. As an examiner, I see daily how promising texts squander their chances for TDN 4 or 5 with just the first sentence. In only 45 days is the next TestDaF date on February 10, 2026, and your opening sentence can determine success or failure.
The Most Common Introduction Mistakes from an Examiner's Perspective
The Copy-Paste Error
Many candidates begin with a direct repetition of the task description:
❌ Weak: "The present graph shows the development of tuition fees in Germany from 2010 to 2020."
✅ Strong: "While higher education is becoming increasingly expensive in many countries, the present graph shows a surprising development of tuition fees in Germany between 2010 and 2020."
From my experience as an examiner, I immediately recognize when someone is just copying the task. This signals a lack of language competence and costs valuable TDN levels right from the introduction.
The Context Killer
Another common mistake is the lack of thematic context:
❌ Weak: "The graph shows numbers about environmental protection."
✅ Strong: "In light of the current climate debate, environmental awareness among the population is gaining increasing importance, as the following graph illustrates."
The strong opening sentence connects the topic with societal developments and demonstrates C1 level.
The Banality Trap
Many candidates use meaningless phrases:
❌ Weak: "Nowadays this topic is very important and interesting."
✅ Strong: "The digitalization of the job market presents both opportunities and challenges, the extent of which the present statistics illustrate."
Why the Opening Sentence Is So Crucial
First Assessment Impulses
As an examiner, I form an assessment of the candidate's language level after just the first two sentences. These first impressions unconsciously influence the entire evaluation. A weak start means the rest of the text must be particularly convincing.
Criterion "Structure and Cohesion"
The opening sentence is the first indicator of text structure. Examiners evaluate here:
- Thematic introduction
- Transition to the graph
- Linguistic connection
- Reader guidance
A successful opening sentence immediately shows that you master the text type.
Vocabulary Demonstration
The introduction is your first chance to demonstrate C1 vocabulary. Many candidates waste this opportunity with B2 standard formulations.
The Anatomy of a Perfect Introduction
Building Block 1: Thematic Hook
Begin with a relevant societal development or current reference:
"Increasing urbanization shapes modern societies worldwide..." "While work forms are fundamentally changing..." "In light of rising healthcare costs..."
Building Block 2: Problem Statement or Relevance
Connect the topic with its significance:
"...this presents urban planners with new challenges." "...employees must adapt to changed requirements." "...prevention gains importance."
Building Block 3: Transition to the Graph
Elegantly transition to data analysis:
"The present statistics illustrate this development using concrete numbers." "As the following graph shows, this trend is reflected in current data."
Complete Example
✅ Optimal Opening Sentence: "While work-life balance is gaining increasing importance for employees, companies face the challenge of developing flexible work models – a development that is clearly reflected in the present survey data on home office usage."
This sentence fulfills all criteria:
- Thematic context (work-life balance)
- Societal relevance (challenge for companies)
- Transition to graph (survey data)
- C1 vocabulary (work-life balance, reflected)
- Complex sentence structure
Avoiding Typical Assessment Pitfalls
Length Extremes
❌ Too short: "The graph shows data." (4 words) ❌ Too long: A sentence with over 40 words that nests multiple subordinate clauses while losing clarity.
✅ Optimal: 20-30 words with clear structure
Linguistic Pitfalls
Avoid Anglicisms: ❌ "The topic is very relevant." ✅ "The subject is of great relevance."
Avoid Colloquial Language: ❌ "Nowadays this is really important." ✅ "Currently, this topic is gaining significance."
Use Modal Particles Sparingly: ❌ "This is surely an important topic." ✅ "This undoubtedly represents a central challenge."
Examiner Perspective: What Convinces Us
Positive Signals
As an examiner, I immediately recognize a strong candidate by:
- Independent thematic approach instead of task copying
- Precise word choice without filler words
- Complex but comprehensible sentence structures
- Thematic connection with societal developments
Negative Signals
These introductions make me take notice:
- Direct repetition of the task description
- Grammar errors already in the first sentence
- B2 standard formulations ("very important," "interesting")
- Missing thematic embedding
Practical Practice Strategies
The 3-Sentence Method
Write three different opening sentences for each practice graph:
- With current societal reference
- With historical classification
- With future perspective
Then choose the strongest one.
Vocabulary Upgrade
Create a list with C1 alternatives for common B2 expressions:
- important → significant, relevant, central
- show → illustrate, demonstrate, prove
- problem → challenge, issue, difficulty
Timing Training
Practice opening sentences under time pressure:
- 2 minutes for graph analysis
- 3 minutes for opening sentence formulation
- 1 minute for revision
Common Myths Debunked
Myth 1: "Longer is better"
Many candidates believe complicated nested sentences would bring higher TDN levels. Actually, examiners rate clarity and precision higher than length.
Myth 2: "Personal opinion belongs in the introduction"
The introduction should remain neutral and factual. Your position comes later in the text.
Myth 3: "Standard formulas are safe"
Formulations like "The present graph shows..." are not wrong, but they don't demonstrate language competence.
Countdown Strategy for February 2026
Week 1-2: Consolidate Basics
- Collect 20 different introduction formulations
- Practice one opening sentence daily
- Analyze sample solutions
Week 3-4: Increase Complexity
- Connect topics with current developments
- Experiment with different sentence structures
- Have introductions evaluated by others
Week 5-6: Automation
- Reduce formulation time to under 5 minutes
- Practice under exam conditions
- Perfect your top 3 formulation patterns
💡 Practice Tip: Write an opening sentence to a current news story every day. This trains the spontaneous connection of topics with societal developments – a core competency for TDN 4 and 5.
