How does it work?

To submit a data sharing request, read the NTR data sharing request procedures and complete the NTR data sharing request form and send it to NTR Data management. To avoid delays, please go through the checklist before submitting your request.

Review process

Data management will check your request for completeness and feasibility. After this, your data request is submitted for review by the NTR Data Access Committee (NTR-DAC). Once the NTR-DAC has reviewed your request (typically within 2 to 4 weeks) you will be informed of the outcome. If the request is not approved, you may be requested to revise the proposal and resubmit.

After approval

Internal applicants (VU employees):
After your data request is approved, you will be asked to sign a data sharing statement. After we receive your signed data sharing statement, your dataset will be prepared.

External applicants:
If you are an external applicant (i.e. not working at the Vrije Universiteit Amsterdam), NTR data management will prepare a data sharing agreement (DSA) that specifies the data access fee to be paid to NTR. This DSA needs to be signed by the managing director of your division as well as the PI of your research project. It will be countersigned by the chair of the NTR management team and the managing director of the Vrije Universiteit Amsterdam.

Since the size of the dataset has to be known in order to determine the access fee, the DSA will be sent to you after creation of the dataset. However, to prevent delays, we recommend early consultation with the responsible officer of your institute. Concept DSA forms can be found here.


The review process by the DAC may take up to 4 weeks. Preparation of a typical dataset will typically take approximately 2 weeks. If your request is particularly complex, more time may be needed; if this is the case, NTR data management will inform you.
