Our Team

Save Our Schools Arizona Network focuses on issues that impact the quality of education provided to children in Arizona’s public schools. 

By tracking and interpreting changes, improvements, and outcomes related to public education in Arizona, we provide information, data and analysis to help people across the state understand the crisis facing Arizona’s public schools. 

Explore our website and read about efforts to stop the nationwide push toward privatization of public education and our continued fight against profit-driven education reform. You will find in-depth analysis of Arizona’s school funding challenges and efforts to improve student achievement. 

Our Vision

We are a non-partisan, community-based organization supporting strong 
public schools for a strong Arizona. 

  • Research public education issues affecting our state in an objective, fact-based manner
  • Engage Arizonans around the topic of public education by sharing research and initiating dialogues around the state
  • Collaborate with other local and national education and community groups, business partners, and other leaders to build support for public education in Arizona
