A complete overview of available data gathered from 2013 to 2020 can be found here [temporarily unavailable, please send an e-mail]. For questions about the available data, please contact

Submitting a data sharing request

Researchers who want to collaborate with the Netherlands Autism Register can fill out this form and contact the NAR via Your data request will be reviewed by the NAR-team. Once the NAR-team has reviewed your request (typically within 2 weeks) you will be informed of the outcome. If the request is not approved, you may be requested to revise the proposal and resubmit.

Once your data request is approved, you will be asked to sign a data sharing agreement (DSA). Once we receive your signed data sharing agreement, data management will prepare your dataset. A typical data request takes approximately 2 weeks to prepare. If your request is particularly complex, more time may be needed. If this is the case, you will be informed of this by NAR data management.

If you have any questions that have not been answered, feel free to contact the NAR team via
