What changed for DUI in 2026

What the DUI is and how it works

According to Texas Department of Licensing and Regulation, “You must have a minimum of an Associate Degree in the field of psychology, sociology, counseling, social work, criminal justice, education, nursing, or health to apply for a Court-Ordered Education Instructor license.”[2]

The exam is run by the Texas Department of Licensing and Regulation (TDLR) for people who want to teach court-ordered drug and alcohol education. Rules differ from state to state, so everything below describes Texas only. If you are certifying somewhere else, check that state's own agency.

TDLR does not publish a content outline or a passing score in the sources we checked, so read the Candidate Information Bulletin as soon as you receive it. Confirm current dates, fees and rules on the TDLR court-ordered education pages before you register.

Worked examples: how to reason through DUI questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What should a DUI instructor do if they suspect a participant is under the influence during class?

  1. Ignore the suspicion and continue teaching
  2. Address the situation privately, encourage the participant to seek help, and report the incident according to program policies
  3. Physically test the participant for impairment
  4. Dismiss the participant without any further action

Answer: B. Address the situation privately, encourage the participant to seek help, and report the incident according to program policies

Explanation:

The correct answer is to address the situation privately, encourage the participant to seek help, and report the incident under program policies. This protects the participant, keeps the class safe, and leaves a record that others can follow up on.

Ignoring the suspicion leaves a possible safety problem in the room and ignores your duty to the program. Physically testing the participant is wrong because an instructor is not there to perform impairment tests, and doing so can create conflict and legal exposure. Dismissing the participant with no further action is wrong because it provides no help, no documentation and no follow-up.

Rule to remember: handle it discreetly, support the person, and document and report through the channels the program sets. Do not diagnose, test or punish on your own.

Example 2

Question: Why is root cause analysis important in quality improvement?

  1. It identifies the underlying cause of problems rather than just symptoms
  2. It assigns blame to specific individuals
  3. It eliminates the need for data collection
  4. It replaces the need for corrective actions

Answer: A. It identifies the underlying cause of problems rather than just symptoms

Explanation:

Root cause analysis matters because it finds the underlying cause of a problem instead of treating only what is visible on the surface. If you fix a symptom, the same problem tends to return.

Assigning blame to individuals is wrong because the method looks at processes and conditions, not at who to punish. Blame also discourages people from reporting problems honestly. Eliminating data collection is wrong because the analysis depends on evidence to show what actually happened. Replacing corrective actions is wrong because the analysis only explains the problem. Corrective actions are still needed to fix it, and the findings tell you which actions are worth taking.

Rule to remember: ask why until you reach the cause, use data to support it, then act on it.

Example 3

Question: What method is most commonly used in DUI education to engage participants in learning about impairment and prevention?

  1. Lectures only
  2. Group discussions and real-life case studies
  3. Hands-on training with alcohol testing tools
  4. Passive reading assignments

Answer: B. Group discussions and real-life case studies

Explanation:

Group discussions and real-life case studies are the right answer. They get participants to think, compare their own experience with the material, and talk about impairment and prevention in practical terms. That kind of involvement is what helps people change behavior.

Lectures only is wrong because one-way delivery gives participants little chance to reflect or respond. Hands-on training with alcohol testing tools is wrong because it is not the most common engagement method in DUI education, and it focuses on equipment rather than on understanding and prevention. Passive reading assignments are wrong because reading alone asks nothing of the participant and is easy to skim without absorbing.

Rule to remember: when a question asks how to engage adult learners, pick the interactive, discussion-based option over the passive one.

How to use these practice tests

Start with the official material. When TDLR sends you the study materials and the Candidate Information Bulletin, read them through and note every topic they name. Our topic list is a practice aid and may not match the bulletin, so let the bulletin decide what you study.

  1. Take a short practice set on each topic area on this page and write down which ones feel weak.
  2. For every miss, read the explanation and write the rule in your own words. Do not just memorize the letter of the answer.
  3. Return to the official materials for each weak topic, then retake that set a few days later to see whether it stuck.
  4. Practise instructor-focused questions on ethics, handling an impaired participant, and engaging adult learners, since these call for judgment more than recall.
  5. Close to test day, do mixed practice under the 1 hour time limit so the pace feels familiar.

Remember the exam is in person in Austin and held once a month, so plan your travel and your registration date well ahead. If you fail, you have 30 days to retake, so keep your notes.

The exam is 1 hour long. The sources we checked do not state the number of questions or the passing score, so look in the Candidate Information Bulletin that TDLR sends after you register.

What happens if I fail?

You have 30 days to retake the exam. If you pass, the license is mailed to you. Exams are held once a month in Austin, so book your retake early enough to fit inside that window.
