It is possible to retake the exam under the following conditions:
- The exam can be retaken only if the KNX training centre agrees with this.
- The exam can be retaken max. 3 times.
- You are allowed to retake that part of the KNX exam you have failed (e.g., theory). The successful part of the exam does not have to be retaken (e.g., practical).
- If you fail after 3 attempts, you need to reattend the complete course.
Note: It is not possible to retake a part of the exam (e.g. theoretical or practical part) at another certified training centre.
