MAT Tool Available with MAT version 5.4 Update

The Measure Authoring Tool (MAT) is once again available for use. We have completed the Update to MAT version 5.4.

This update contains the system fix to correct the version numbers for some of the files in the Measure Package. For more information on this update, please see the release notes posted to the Training and Resources page of the MAT public website

To see the changes in the version numbers on the exports, Measure Developers will need to re-package and re-export their measures. If a measure is currently in a versioned state, a new draft will need to be created which will enable the measure to be re-packaged.

If you have any questions or concerns regarding this update, please use the Contact Us form on the Contact Us page of the MAT Public website ( or send an email to
