Depending on the county or state, an individual might need to take a refresher course when renewing an online ServSafe certification. Certifications last only a few years, and they must be updated as food safety techniques change.
ServSafe offers a food safety examination retest program for those who completed the online course and need to take proctored exams, or for those who need to retest for their ServSafe certifications. ServSafe also offers a one-day course as a condensed version of the initial certification class. Six-hour refresher courses for Servsafe recertification are also available in some areas, but the health departments of some counties do not accept them.
