The Educators Without Borders Team

Educators Without Borders – presented by SchoolRubric – convenes leading voices in education to discuss trends, news, and issues facing global education today. Our production team strives to outreach and connect with a diverse, knowledgeable, and engaging group for each episode and panel we assemble. Panelists bring a mixture of evidence-based practices, research-based knowledge, and personality to prompts and questions posed by a group of likeminded peers. One of the unique features of Educators Without Borders is that we truly believe that each educator shifts through different roles ranging from leader to follower, learner to teacher, moderator to panelist, and panelist to viewer. In this spirit, we create a community to engaged educators looking to learn from each other, connect, and improve outcomes for all students.


We are always looking for new episode ideas and passionate educators to join our panels. If you have any interest in participating in an upcoming episode of Educators Without Borders, have an episode suggestion, or are interested in joining our team, please email us at
