About the Centraal Diploma Register


In the CDR (Centraal Diploma Register) you can check the validity of personal diplomas regarding VCA, SOG-petrochemie, SVWOH and NOGEPA. The register gives insight on expiration dates of the diploma as well, so you know when a renewal is needed.
To search in the CDR you need the diploma number or at least 3 following characters of the last name of the diploma holder in combination with the date of birth of that person.


In the CDR you can find:


  • VCA-diploma's (B-VCA, VOL-VCA and VIL-VCA)
  • SOG-petrochemie diplomas from the course- and trainings guide from SSVV
  • SVWOH-diplomas from the scaffolding courses
  • NOGEPA-diplomas and certificates from the NOGEPA courses

There is a connection with the Belgium CDR, for combined search results. Other foreign diplomas and equivalents of the VCA- and SOG-petrochemie-diplomas are not registered in the CDR. You can find more information about VCA equivalents in this document and for SOG-petrochemie in this document.
