Socratic Society is a place for thoughtful students to gather to consider complex and difficult questions. Each month, the group tackles a new issue, working collaboratively to try to work out responses to questions that often have no easy answer; do we have a right to die? is some art 'better' than others? are we required to respect everyone's opinion? Using the Socratic method of asking even more questions, the students work to unravel the depth and complexity of these ideas and, in so doing, learn more about themselves, each other, and their roles as active and engaged citizens.

Where Purple? was formed by students, along with members of the Seacoast Community, in response to the numerous suicides of LGBT youth in the Fall of 2010.  The group takes part in Spirit Day, Wear Purple Day, and other events.  Their goal is to eliminate bullying in all forms and to create a community at CATA that is virtually purple, or safe, at all times for all people.
