Trainees do not need a license. They will use the User Name and Unlocking number of the person signing their reports.

To do this, click Help→Registration and enter the appraiser's User Name and Unlocking number and click resister. 



In order for both signatures to appear, a dual certification form needs to be added.
When a dual certification page is in the report, there are additional options when affixing signatures.
The appraiser will choose Affix Signature as Appraiser. The trainee will choose Affix Signature as Co-Appraiser.
