At the Elementary School, the institution of Student Communities operates for each class from 4th to 6th Grade, alongside the overarching Student Council for the entire school. The primary goals of these institutions are:

• Active participation of students in school operations by contributing to decisions that concern them, taking initiatives, providing constructive criticism, learning to engage in dialogue, proposing ideas in an organized manner, and cultivating a sense of social responsibility.
• Development of mutual respect, responsibility, self-discipline, and freedom of expression.
• Formation of harmonious and constructive collaborative relationships among students, teachers, and parents/guardians to address issues concerning the educational community.
• Familiarization and experience with the processes that govern the democratic organization of social groups.

The Student Communities has been in place at Pierce since 1927. These goals, as well as the specific terms of their formation and function, are closely linked to the school’s philosophy, encapsulated in the phrase: “Not to be served, but to serve” (Non ministrari, sed ministrare). Naturally, the operation of these institutions is adapted to the needs and abilities of elementary-aged children.
