 Peer leaders chosen are typically gregarious and outgoing, and females comprised 65% of the peer force within the 2008–2009 Somerville High School school year.Through a series of group examinations in which random peer applicants are given physical leadership puzzles to complete within specified time periods, the most outspoken individuals are looked upon highly.Through group interviews that follow, seniors that are similarly self-confident and socially agreeable are chosen as peer leaders.
