Last updated: 17 October 2026 · Verified against official exam guidelines and grading rubrics
For self-study candidates, Writing (Schreiben) is the hardest module to prepare for: Reading and Listening have answer keys, but an answer key cannot tell you how many points your email, forum post, or argumentative essay would earn. Here is a complete comparison of the tools available to grade and improve your German exam writing.

Where Candidates Lose Points in Goethe, telc & TestDaF Schreiben
- Goethe B1 & B2 Schreiben: Omitting one of the required Leitpunkte, writing repetitive main clauses without connectors, or using the wrong formality register.
- telc B1 & B2 Schreiben: Mismatched salutation (Anrede) and sign-off (Grußformel), or addressing less than the required four content points.
- Digital TestDaF Schreiben: Copying numbers from the chart without linking them to the reading text arguments or failing to justify your own stance (required for TDN 4+).
How Zertifly's Rubric-Based Writing Evaluator Works
When you submit a Writing task on Zertifly, the engine evaluates your text against the exact prompt you solved. First, it verifies whether every required content point was addressed fully.
