The reliability and usability testing of the AGREE-REX is underway!

10 November 2016

We have received a significant amount of interest from the guideline enterprise community and are appreciative of those who have participated and provided their feedback.

To be able to provide a high level of confidence in the reliability of the AGREE-REX, we are still in need of participants to complete an AGREE-REX appraisal and usability survey. If you are interested, please see our AGREE-REX research page to learn more or to sign up.

In addition, the AGREE-REX could serve as a very helpful tool to assist guideline development groups in deciding whether to adopt, adapt, endorse, or implement a guideline in their context. For more information on how to participate in this opportunity, please contact us at
