Have a look at http://faamed.info and it’s FAQs which has the flowchart that will be used and other information.
For that level and one DUI looks like you will need “Requires Chemical Abuse Depenency Counselor evaluation of 5 factors of tolerance, withdrawal, lifestyle centered on use, continued use in the face of bad outcomes, and blackouts.”
