Lobbyists represent the interests of an organization by meeting regularly with lawmakers to persuade them to promote the interests of the organization or its constituents. To become a lobbyist, you normally need a college degree, though you don't necessarily need a master's degree in public affairs to grow in this career.
Political science, communications, PR, economics and journalism are common undergraduate degrees for lobbyists, according to "The Princeton Review." Along with the education, employers look for effective communication abilities, organizational skills and initiative. A master's of public affairs can certainly increase your potential for more lobbying jobs with larger organizations that may pay more money.
