The bill authorizes the implementation of ranked choice voting in the town of Arlington by amending Chapter 503 of the acts of 1952. It introduces a new section, Section 8B, which defines key terms related to ranked choice voting, such as "concluded ballot," "continuing candidate," and "highest-ranked continuing candidate." The bill stipulates that select board members, school committee members, moderators, elected members of the board of the housing authority, and assessors will be elected using ranked choice voting, with specific exceptions for single-seat and multi-seat offices based on the number of candidates. The tabulation process for votes is outlined, including how to handle concluded ballots and tie situations.

Additionally, the bill mandates that the town clerk will oversee the ranked choice voting process, including making necessary changes to ensure election integrity, and will publish election results showing the tabulation by rounds. A question regarding the acceptance of this act will be placed on the ballot for voters during a regular or special election, and if a majority votes in favor, the act will take effect in Arlington.
