The National Network of State Teachers of the Year (NNSTOY) is a network of State Teachers of the Year and Finalists who use their teacher leadership to ensure that every student receives an outstanding education. They do this through their focus on professional practice, policy and advocacy. 

Professional Practice. They devote their time, resources and expertise on strengthening their own practice and that of colleagues. They do this through mentoring, coaching, sharing, and offering professional learning in teacher leadership and through NNSTOY fellowships.

Policy.  They work with policymakers,  influencers and education administrators to promote the conditions, capacity and culture needed to support great teaching and learning.

Advocacy. They seek to involve the nation's outstanding educators in decisions that affect teaching and learning. They advocate for critical reforms that improve learning for all students, especially those who are most at risk.
