About Us

OESIS is a faculty-focused innovation network of over 550 independent schools (See list below). Our network focuses on changing the learning models of schools with an emphasis on the innovative practices in pedagogy, curriculum development, and school culture change. We have grown from a focus on online learning now to cover all areas of student-centered learning including Project-based learning, Mastery, 21st Century Standards-Based, STEAM, Design-Based PRBL, Blended Learning, Inquiry Driven Models and more. Our network encourages real 21st century collaboration through our online platform OESIS-XP, through our anchor Conferences in Boston, Los Angeles and China, and our @ School conference Programs. Our mission is to catalyze the considerable 21st century opportunities for independent school growth. We do that by maximizing collaboration between the many schools that constitute the independent school tapestry, by provoking innovative conversations, by globalizing connections for independent schools and by using research and information to lead.

*The 2018-2019 Academic Innovation Survey is now open for senior administrators at independent schools.  This survey takes 10-12 minutes. The results will be provided free to survey-respondents.
