Updated and Improved Standards Review Database
The online standards review database has been updated to provide greater functionality, offering a single sign in feature with dashboard, so users can easily access and highlight those items that require attention. The new system reduces staff and volunteer time by allowing committees to do all of their letter ballots in the system, track most committee activity online and download ballot reports.
