To maintain the quality of KNX training and ensure that KNX tutors regularly apply and keep their knowledge up to date, KNX certified training centres are recommended to organize a certain number of KNX certified courses each year.
The recommended annual course frequency depends on the certification level of the training centre:
| Training centre certification level | Recommended course frequency per year |
| KNX certified training centre | At least 4 KNX Basic courses |
| KNX+ certified training centre | At least 4 KNX Basic courses and 2 KNX Advanced courses |
| KNX++ certified training centre | At least 4 KNX Basic courses, 2 KNX Advanced courses and 1 KNX Tutor course |
These course frequencies are recommendations intended to help training centres and their KNX tutors maintain their training experience and technical knowledge.
