The MAT Staging environment will need to change over to the MAT version 5.5 on April 26th, 2018 to allow for the MAT version 5.5 user acceptance testing (UAT). This means that the last day to access any of your MAT version 5.4 data in the staging environment will be April 25, 2018. Any user accounts that are not associated with the MAT version 5.5 UAT will be disabled on this date.

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 www.emeasuretool.cms.gov.

The Measure Authoring Tool (MAT) will be unavailable the evening of Monday, March 19, 2018 from 8:00PM ET to 11:00PM ET to allow for an update to be made to the MAT version 5.4. This update will correct the version number issue currently showing in the MAT packages. Release notes will be posted to the MAT public website on the Training and Resources page following the update.

Following this release, it is recommended that Measure Developers re-package and re-export any previously created measure packages to see the updated file version numbers.

The Measure Authoring Tool (MAT) may be unavailable from approximately Friday, January 12, 2017 at 9:00PM ET through Saturday, January 13, 2017 at 3:00PM ET due to regularly scheduled system maintenance. This downtime may affect both the Production and the Staging environments of the MAT.
