Evidence Ratings
Scientifically Supported: Strategies with this rating are most likely to make a difference. These strategies have been tested in many robust studies with consistently positive results.
Some Evidence: Strategies with this rating are likely to work, but further research is needed to confirm effects. These strategies have been tested more than once and results trend positive overall.
Expert Opinion: Strategies with this rating are recommended by credible, impartial experts but have limited research documenting effects; further research, often with stronger designs, is needed to confirm effects.
Insufficient Evidence: Strategies with this rating have limited research documenting effects. These strategies need further research, often with stronger designs, to confirm effects.
Mixed Evidence: Strategies with this rating have been tested more than once and results are inconsistent or trend negative; further research is needed to confirm effects.
Evidence of Ineffectiveness: Strategies with this rating are not good investments. These strategies have been tested in many robust studies with consistently negative and sometimes harmful results. Learn more about our methods

Health factors shape the health of individuals and communities. Everything from our education to our environments impacts our health. Modifying these clinical, behavioral, social, economic, and environmental factors can influence how long and how well people live, now and in the future.
Age of seller and server laws set a minimum age for sellers in off-premise locations that sell alcohol and servers and bartenders in on-premise locations. Some states specify a separate minimum age to handle beer, wine, and spirits, and require a manager or supervisor to be present when an underage employee sells, serves, or dispenses alcoholic beverages1.
What could this strategy improve?
Expected Benefits
Our evidence rating is based on the likelihood of achieving these outcomes:
Reduced underage drinking
Potential Benefits
Our evidence rating is not based on these outcomes, but these benefits may also be possible:
Reduced alcohol-related crashes
What does the research say about effectiveness?
There is insufficient evidence to determine whether age of seller and server policies reduce underage drinking. Available evidence suggests that underage sellers are more likely to sell alcohol to customers under the age of 212, 3 and to intoxicated patrons4. States with legislation that requires a minimum age of 21 for bartenders appear to have fewer alcohol-related fatal crashes among underage drivers than states with a younger minimum age or no required age5, 6; however, regulations that establish a minimum age for sellers and servers do not appear to affect alcohol-related fatal crashes5, 6, 7. Additional evidence is needed to confirm effects.
How could this strategy impact health disparities? This strategy is rated no impact on disparities likely.
Implementation Examples
The minimum age required for sellers in off-premise locations and servers and bartenders in on-premise locations varies by state. As of January 2016, the minimum age to serve alcohoic beverages ranges from 17 in Maine to 21 in Alaska, Nevada, and Utah; most states set a minimum age of 18. Ten states require a manager to be present when underage servers are working8.
