Welcome to NDC-RI
Nederlands Duikcentrum Registratie Instelling (Dutch Divecentre Registration Institution)
Welcome to the website of NDC-RI, the registration institution in the field of working under pressure. As of 1-2-2025 NDC-CI (certifying institution) has changed to NDC-RI (registering institution).
Appointed by the Ministry of Social Affairs and Employment (SZW), NDC-RI carries out its task as a Registration Body within the current Dutch Registration System. Extensive information about the system can be found on the Arboportaal (SZW) and on the SWOD website.
NDC has been a well-known concept for over 35 years, both nationally and internationally. Professional divers and diving team leaders with an NDC certificate benefit greatly from the broad international recognition of the certificate.
APPLY FOR REGISTRATION, PORTFOLIO-CHECK or REREGISTRATION
Applying for your registration is easy via the NDC-RI Portaal. In your personal digital environment you always have a clear overview of your certificates and you can easily request your portfolio check or re-registration.

EXAMS AND PRACTICAL TESTS
From 1 July 2024, all exams will be administered by Hobéon SKO. To make an appointment for an exam, you can contact Hóbeon directly. You will find the link here: Examens Hobeon SKO
When applying for initial registration, your certification application must be submitted to NDC-RI prior to taking the exam.
In case of re-registration, we request that you submit your re-registration application to NDC-RI in good time. You can make an appointment with Hobéon for a practical exam (Diver) or Practical and Theory exam (Dive supervisor) immediately after the application, but also prior to the application. Of course, you must have completed both the application and the exams before the expiration date of your certificate.

Currently there are no additional exemption regulations established by the Ministry of Social Affairs and Employment in connection with Covid. If you have any questions about this, you can send an email to
