Assessment Summary

DUI-DWI Offender Test (DDOT)

The DUI/DWI Offender Test is a 117-item, self-administered test that includes a Marijuana Scale. It takes 20 minutes to complete and is computer scored, with DDOT reports printed in 2 1/2 minutes, from data (answers) entry. DDOT recommendations are DUI/DWI program oriented. DDOT was designed for DUI/DWI offender assessment and was (and continues to be) standardized on DUI/DWI offenders


  1. Truthfulness Scale
  2. Alcohol Scale
  3. Drug Scale
  4. Marijuana Scale
  5. Driver Risk Scale
  6. DSM-5 Substance Use Disorder

The DDOT is a self-report test that is completed by the client, either individually or in group settings. There are no forms or questionnaires to be completed by the staff. The DDOT is scored and interpreted by the computer that generates printed DDOT reports on-site within three minutes of test completion. These reports eliminate the need for tedious, time consuming and error prone hand scoring. Staff report writing, substantiation of decision making and record keeping needs are met with DDOT reports.
