SODAT-Delaware, Inc. is authorized by the Office of Highway Safety to operate the DUI
Evaluation and Referral Program (DERP). Every individual who is arrested in the State of Delaware
for a DUI violation, or is otherwise under Delaware’s jurisdiction for a DUI offense, is evaluated
by SODAT and then referred to an educational or treatment agency, as appropriate.
DERP’s administrative offices are located in New Castle County, but evaluations are done in all
three counties in the state of Delaware. Your DUI evaluation will be scheduled at the office most
convenient to you.
The DUI evaluation takes approximately 90 minutes and involves an interview with a trained evaluator.
Within five (5) to 10 business days following the completion of your DUI evaluation, you will
receive a letter with your referral and all of the information you will need to schedule your classes.
The fees for this service are as follows:
No Show/Cancellation Fee:
$35 (for failure to cancel within 24 hours)
$35 (for changing from one DUI provider to another, once initially referred)
We accept cash, money orders, and certified checks, as well as Visa, MasterCard, Discover.
Credit cards must be in the name of the person being evaluated. We do not accept personal checks.
