When Maryland uses a selection test for a state job, 10 points are added to your passing score as a veteran with an honorable discharge or a certificate of satisfactory completion, as the spouse of a veteran with a service-connected disability, or as the surviving spouse of a deceased eligible veteran. A former prisoner of war gets 2 more points, and an applicant with a disability as defined by the Americans with Disabilities Act gets 5 more.
Claim the credit when you apply for a state job through the Maryland Department of Budget and Management, and upload your service documentation with the application.
Your DD214 or other documentation of service, plus proof of disability if you are claiming as a disabled veteran, and a marriage certificate or death certificate if you are claiming as a spouse or surviving spouse.
