NAIS believes that in order to survive and thrive in the 21st Century, schools should address sustainability on five dimensions.
Demographic Sustainability: becoming more inclusive and representative of the school-age population and less unapproachable financially and socially
Environmental Sustainability: incorporating sustainability practices into teaching and practice; becoming more green and less wasteful
Financial Sustainability: becoming more efficient and less costly
Global Sustainability: becoming more networked internationally and less parochial in outlook
Programmatic Sustainability: becoming more focused on the skills and values that the marketplace of the 21st Century will seek and reward, and less narrowly isolated in a traditional disciplines approach to teaching and learning
