The constitution of iMMO (available in Dutch only) recognizes the following organs:

  • board (‘bestuur’)
  • advisory council (‘adviesraad’)
  • general manager (‘directie’).

iMMO has a permanent core bureau (‘staf en medewerkers’) comprising medical, psychological and legal expertise. These staff members cooperate with a network of assessors (‘rapporteurs’), professionals – as a rule physicians and psychologists – who perform the actual assessments (on a voluntary basis). The office manager and legal assistant, provide logistic and administrative support.

The general manager has the overall management responsibility for the organization; she also primarily represents iMMO in the relationship to external parties.

The consultation group (‘consultatiegroep’) is composed of a number of experienced assessors, who have a role in the quality assurance of assessments and the training of new assessors.
