About SURF
SURF is a cooperative association of Dutch educational and research institutions in which the members combine their strengths. Within SURF, we work together to acquire or develop the best possible digital services, and to encourage knowledge sharing through continuous innovation. The members are the owners of SURF.
SURF Cooperative

There is a growing awareness in society and education that the deployment of intelligent technology requires reflection and guidance to exploit opportunities and manage risks, which the technology also entails.

Members' council, BoD, SB, WTR

Curious about SURF's organisational structure? In brief:

The members' council represents the members (owners of the cooperative) and is the highest body of the cooperative. The members' council meets at least twice a year.

The Executive Board (BoG) formulates SURF's policy and strategy and translates it into tactical and operational matters.

The Scientific Technical Council (WTR) is an independent advisory body. The council advises, solicited and unsolicited, on strategic, scientific and technical issues of the cooperative.

The Supervisory Board (SB) supervises the policies of the Board and the general affairs of the cooperative and its affiliated enterprise(s). The SB acts as an employer of and a sounding board for the Board.

Council of Members

The members' council represents the members (owners of the cooperative) and is the highest body of the cooperative. The members' council meets at least twice a year.

Tasks of the member council

  • adopt articles of association
  • approve the annual accounts
  • approve the Long-term Agenda (the strategy) and the annual plans of the SURF cooperative
  • appointing the members of the Supervisory Board, the Executive Board, and the WTR
  • approve the admission of new members

Distribution of members

The Members' Council consists of 36 members divided into six departments. A set number of seats is available for each department. Members are assigned to one of the member council's departments, which takes decisions on behalf of the members. Thus, the voice of all members is heard. Members serve on the members' council for a maximum of 4 years and can be reappointed 2 times by their department.

Department Maximum number of members To be appointed by
Academic education 14 Universities
Higher professional education 10 Universities of applied sciences, via the Association of Universities of Applied Sciences
Secondary vocational education 5 MBOs, via the MBO Council
Non-commercial and non-university research 3 - 1 by NWO
- 1 by KNAW
- 1 by the Council of Members
University medical centres 2 Umc's, through the NFU
Other 2 TNO and Royal Library

Method of decision-making

Decision-making is based on an absolute majority (more than half) of the valid votes cast, unless the statutes or the law prescribe a larger majority.

The chairman of the WTR or a deputy appointed by him or her is authorised to attend meetings of the Members' Council and has an advisory vote.

Governance code

Through the Members' Council, the members have a say in matters such as SURF's strategy and the (core) package of services. To exercise that control, in addition to the involvement of our members, SURF also needs transparency about its management and supervision. We have therefore drawn up a governance code, which contains widely supported general views on good corporate governance and rules of conduct. The governance code also requires the board of directors to draw up a whistleblower policy and publish it on the website.

Appointment of WTR members

The WTR consists of recognised independent authorities appointed in their personal capacity. WTR members are appointed on the basis of their independent outlook, vision of the future and expertise in the cooperative's fields of activity. Appointment is always for a term of 3 years with a maximum of 3 terms. New WTR members are nominated by the Supervisory Board and appointed by the Members' Council. The composition of the WTR is evaluated every 2 years. If vacancies arise, their filling is discussed with the Executive and Supervisory Boards.

Role WTR

The WTR's role is broad:

  • Performs a substantive review of projects and activities initiated by SURF.
  • Supports the sectors in formulating their positions and priorities.
  • Advises SURF's Executive Board and Member Council on the level of innovation in the Multi-Year Plans and 2-Year Plans. 2 years after publication of the trend report, the WTR reassesses the trends and issues described.
  • Makes recommendations for tightening or changing the chosen course in the 2Year Plans. This is done on the basis of progress reports of the cooperative's entire portfolio: service delivery, service development and innovation.

The WTR as a whole issues the recommendations. A committee, composed in consultation with the client, prepares the opinions. In carrying out its work, the WTR may additionally be assisted by external experts.

WTR also advises institutions

The WTR advises SURF member institutions seeking an independent and expert response to questions regarding ICT policy. Institutions can contact the WTR for audits, support in planning and reviewing policy. The WTR's advice is always tailor-made. The diversity of expertise of the WTR's council members allows it to make quick diagnoses and formulate concrete advice.

View WTR opinions

Advice from the WTR to SURF is in principle public, unless other arrangements have been made. Advice from the WTR to institutions is only public if the client explicitly opts for this.

The WTR considers topics of strategic importance to SURF. The starting point is innovation in current and future services to the members, based on national and international developments.
