In 2009, Ma'yan's second cohort of Research Training Interns decided to find out how Bat Mitzvah is experienced and understood by girls today. The Research Training Internship (RTI) is grounded in the principles of Participatory Action Research, which means that we conduct research as a collaborative, intergenerational team -- researching with Jewish teen girls instead of on them. Using an online survey and a novel research method (asking participants to write endings to fictional Bat Mitzvah-related scenarios), we gathered data from pre- and post-Bat Mitzvah girls in the Tri-State area.
