A key advantage of the telc language examination system is its comparability. This means that an exam passed in German at level B1 (intermediate), for example, is the same as an exam in French or English at the same level. The grading is also comparable. All exams at a given level have the same structure.

telc exams test practical skills acquired by foreign language learners, such as:

• the ability to read to grasp specific information (finding the price of a single room in a hotel brochure),
• the ability to listen and grasp the departure time of a train in a recorded announcement from a station,
• the ability to write a letter asking about room rates,
• during a conversation, the ability to persuade another person to go to the cinema to see a film of one's choice.
• the ability to apply grammar in a specific situation or context, for example, by supplementing a formal letter to an institution with appropriate forms of verbs, nouns, etc.

The telc exam essentially consists of a written and an oral section. The written section consists of reading and listening comprehension; the oral section consists of a conversation in the given language. Individual sections of the exam may vary somewhat depending on the level, but not the language. The structure of the B1 (intermediate) exam is identical for all languages ​​and is as follows: The written section tests the ability to understand the general meaning of authentic texts that must be read and listened to. The next task is to write a letter to an institution or individual. The grammar section involves filling in the missing words in the texts. The oral section consists of three tasks that two candidates must complete together in a conversation.
