On September 29 and 30, 2023, WOSD had its 5-yearly ISO audit again.

During this very intensive audit, all ISO-certified WOSD training courses and the general WOSD structure are checked according to internationally established rules and standards. Not only are all textbooks, manuals and forms checked, but real-time lessons are also evaluated and interviews are held with instructors and students about their previous training, what they learn, where they can find the (lesson) information, etc.

We are therefore pleased to report that this audit has been completed with an 'excellent' result and that we have been ISO certified for another 5 years. This ISO recognition means that WOSD courses are recognized by governments of more than 163 countries in the world.
