Arizona adds points to your passing score on a state employment exam. Veterans who served at least six months of active duty with an honorable discharge, and former reserve component members eligible for military retired pay, get 5 points. Veterans with an honorable discharge who have a service-connected disability rating or receive VA compensation or disability retirement benefits get 10 points. Spouses and surviving spouses get 5 points. If the hiring process does not use numerical scores, you get the preference through preference codes on your application instead.
Claim the preference when you apply for Arizona public employment and attach your supporting documents.
Your DD214, plus a VA rating or award letter, marriage certificate, or casualty documentation depending on which preference you are claiming.
