Bars and taverns range from those serving only beverages to those that also offer snacks or entire meals. Certificate programs in bar management may also be under titles such as hospitality management or food and beverage management. A bar management program may focus solely on bar operations while a hospitality or food and beverage management program may teach business principles for the industry as a whole. Relevant programs can be found at colleges, universities and culinary institutes. Graduates of undergraduate degree programs may choose to continue their education in hospitality management at the master's and doctoral levels, which are research-intensive.
