The working language of the 2025 ISST Congress is English. For everyone to better understand the content of the presentations, the ISST Congress will provide the technical facilities to allow the translation of some presentations from English into other languages. We only offer this translation in the main hall, the “Lamoraalzaal”, which is intended for the keynote speakers and certain workshops. ISST member societies will soon receive communication and a feedback link where you will be asked to indicate your language preferences.
