Certification - VVSOR - VVSOR



Employers, government institutions and society at large increasingly make demands on biostatisticians who design and analyse biological, medical and agricultural research. For this reason the VVS-OR, in cooperation with BMS-ANed, inaugurated the Register of Biostatisticians in 1999. This register guarantees that a biostatistician – in the opinion of the occupational group of statisticians in the Netherlands – has sufficient theoretical knowledge and experience to be able to function as an independent biostatistician.


Biostatisticians who fulfil the requirements stated in the Rules and Regulations for the Registration of Biostatisticians can be entered in the register.

The general requirements are:

  • a Master’s degree with at least 42 units of credit (‘studiepunten’) in statistics/calculation of probability/methodology of a satisfactory level
  • at least five years of practical experience in applying biostatistical methods, of which at least two years with personal responsibility for the biostatistical work
  • the signatures of two registered biostatisticians to testify to the applicant’s experience

All applications are judged by the Board for Registration of Biostatisticians. Any conflicts will be governed by the Regulations for Appeal.


You are invited to apply for entry into the VVS Register of Biostatisticians by filling out the application form and sending it to cbalje@author.nl. The Registration Board charges € 60 (VAT not applicable) for each application to cover administrative expenses. Possible referees regarding the required practical experience can be found in the Public Register; this register only contains information on the registered biostatisticians who have no objections against publicity.
