Illinois BASSET Study Guide 2026

BASSET training

BASSET stands for Beverage Alcohol Sellers and Servers Education and Training. The Illinois Liquor Control Commission (ILCC) licenses the companies and trainers that teach BASSET courses, both online and in classrooms.

• People who serve or sell alcohol for on-premises consumption, such as bartenders and servers, and their managers must complete BASSET training.
• Training must be finished within 120 days of starting the job.
• Certification must be renewed every three years.
• Use a provider licensed by the ILCC, or your training may not count.

Illinois alcohol law for servers

Illinois alcohol rules come from the Liquor Control Act of 1934 (235 ILCS 5). The legal age to buy or drink alcohol is 21.

State and local licenses

Illinois uses a two-level system. A business needs a state liquor license from the ILCC and a local liquor license. In a city or village, the mayor or village president usually acts as the local liquor control commissioner and can fine, suspend or revoke a local license.

Minors

Selling or giving alcohol to a person under 21 is a Class A misdemeanor, and the business can also face penalties against its license. Illinois, like many states, prints vertical licenses for drivers under 21; always check the date of birth, because the person may have turned 21 since the card was issued.

The Dram Shop Act

The Dram Shop Act (section 6-21) lets people who are injured by an intoxicated person bring a claim against the business that sold or gave that person the alcohol. The law limits the amount of damages, and the limits are adjusted every year. Responsible service is the best way to avoid these claims.

Responsible service skills

Illinois sets its own rules, but the skills below are taught in every responsible alcohol service course and appear on every exam.

Standard drinks

A U.S. standard drink holds about 14 grams (0.6 fluid ounces) of pure alcohol.

Big pours and strong cocktails can hold two or three standard drinks in one glass. Proof is twice the alcohol percentage, so 80 proof means 40% alcohol.

Blood alcohol

• Fast drinking and an empty stomach raise BAC quickly; food slows it down.
• Smaller people and most women reach a higher BAC from the same drinks.
• The body removes roughly one standard drink an hour. Only time lowers BAC.
• BAC can keep rising after the last drink.
• Every state sets 0.08% as the limit for drivers 21 and older, except Utah at 0.05%.

Signs of intoxication

• Lowered inhibitions: louder, overly friendly, more talkative.
• Impaired judgment: rude comments, buying rounds for strangers, drinking faster.
• Slowed reactions: slurred speech, glassy eyes, slow answers.
• Loss of coordination: stumbling, swaying, spilling drinks.

Look for changes in behavior and keep track of how much each customer drinks. If someone seems far more impaired than their drinks explain, their drink may have been spiked; get help.

Refusing service

1. Tell your manager and co-workers.
2. Speak privately, calmly and firmly. Point to the law or house policy.
3. Offer food, water or a non-alcoholic drink.
4. Do not serve drinks that others buy for the customer.
5. Help arrange a safe ride, and call police if an impaired customer drives.
6. Write the incident in the log.

Checking ID

The minimum legal drinking age is 21 in every state. Accept only valid, government-issued photo ID. Compare the photo and description with the customer, check the date of birth and expiration date, and feel for tampering. Watch for borrowed, altered and counterfeit IDs. The REAL ID star does not show age.

If you find a fake ID

1. Stay calm and do not accuse the customer.
2. Politely refuse the sale and explain that you cannot accept the ID.
3. Follow your state law and house policy on whether to keep, return or report the ID.
4. Tell your manager.
5. Write what happened in the incident log, including the time and a description of the ID.

Preventing over-service

• Offer food early, especially to customers who are drinking on an empty stomach.
• Serve water with drinks and suggest non-alcoholic options.
• Pace service: do not bring a new drink while the last one is still full, and avoid serving more than one drink at a time to one person.
• Measure pours. Free pours and large glasses can turn one order into two or three standard drinks.
• Never offer drinking games, contests or "bottomless" specials that push people to drink fast.

Alcohol overdose

Signs of alcohol overdose include confusion, vomiting, seizures, slow or irregular breathing, pale or bluish skin, low body temperature and being hard to wake. Call 911 right away. Stay with the person, keep them on their side so they do not choke, and never leave them to "sleep it off."

Liability

Illegal service can lead to criminal charges, administrative penalties against the license, and civil lawsuits under dram shop laws. Careful ID checks, early refusals and good incident records protect you, your customers and your employer.

Exam tips

• Remember the two key numbers: 120 days to complete training after you start work, and renewal every 3 years.
• Know who runs the system: the ILCC licenses BASSET providers and state liquor licenses, and local liquor control commissioners handle local licenses.
• Expect questions on the Dram Shop Act, sales to people under 21, and how to refuse service.
• Check that your course provider is licensed by the ILCC before you pay.
