The AI Policy Labs network, an initiative of the EdSAFE AI Alliance, unites U.S. school districts and states in a collaborative effort to navigate the integration of artificial intelligence in K-12 education. Guided by the Alliance's SAFE framework (Safety, Accountability, Fairness, Efficacy), these labs work together using an open science approach to develop a comprehensive "policy stack." This includes creating practical, shared resources like acceptable use policies, guidelines for parent communication and consent, professional development materials, and ethical frameworks to ensure the responsible, equitable, and effective deployment of AI technologies in schools nationwide.
