Help and Guidance


The AOP-Wiki help pages provide descriptions of each field in the wiki and includes links to the relevant sections in the AOP Developers' Handbook for more information.

The online AOP Developers' Handbook contains all the information from the OECD AOP Developers' Handbook in a web accessible format. The original document is still available for download.

If you have any questions that are not addressed below please check the AOP Forum and/or Frequently Asked Questions page.

Training Wiki

We have launched a training wiki to allow users to learn the new system before making changes on the new production wiki. You do not need to be an author on this wiki to be granted author status on the training wiki, but all information in the training wiki is purged periodically and no mechanism exists to migrate information from that system to this one. If you would like to request author privileges on the training wiki, please contact us at
