The NGSS represent an unprecedented opportunity for the environmental and sustainability education community. They promise to dramatically change the focus and process of k-12 science education in the United States. The good news is that NGSS is strong on environmental content, much stronger than what is being taught now in the vast majority of schools throughout the nation. However, it is not a given that the transition to the new standards will occur widely and quickly. The extent to which the EE community can help those states seeking to implement the NGSS to do so quickly and effectively will help determine the degree of penetration of both NGSS - and its associated EE content - into the nation's classrooms.
