Parent volunteers play an important role at LGCS.
The main vehicle for volunteering is the LGCS Parent Association, which organizes the school's book fair, and events for students. Each classroom has at least one class parent who helps arrange for parents to volunteer in the classroom, reading to students, or assisting teachers and aides. Parents with a particular expertise can talk with students about their specialties. They can also serve as chaperones on the weekly field-study trips to educational sites in Brooklyn.
