Berkshire School uses a conceptual model to present sustainability as the pursuit toward three interrelated objectives: 1) environmental integrity; 2) economic justice; and 3) social equity. In this definition, the community is encouraged to think about sustainability from any of these three perspectives.
Success is assessed using the Protostar sustainability metric adapted from the Sustainability, Tracking, Assessment and Rating Systems (STARS) used in higher education. Protostar is a broad-based, stakeholder-designed, tested framework. It is transparent, self-reporting, and enables meaningful comparisons over time and across institutions using a common set of measurements.
