In 1993, MML created its oldest ambassador program, Municipal Government Works (MGW), to promote citizens' awareness of and interest in the government in their communities. Through school visits, MML members have educated over 51,000 students and their teachers about how municipal government works. 

Historically, MGW Month was celebrated as a week-long initiative in April from 1993 through 2004, known as Municipal Government Works Week. In 2005, MGW became a month-long initiative before moving to November in 2008.
