The Board of Selectmen is the executive body charged with doing what is necessary to carry out the vote of the people at town meeting. Each year at town meeting the voters approve warrant articles that spell out what they want done during the upcoming year; the Selectmen are ultimately responsible for the expenditures, personnel, policies, contracts, etc. that are needed to implement those town meeting votes.
Andover has a three member Selectboard. One member is elected each March to a three year term.
