Teachers Without Borders (TWB) is an international organization launched in 2000, with a mission to connect teachers to information and each other in order to close the education divide and based upon the premise that teachers are community change agents and key catalysts of global development priorities. The programs are led by teachers from all over the world from members of around 171 countries. The organization was founded by Dr. Fred Mednick who believed combining teachers professional development and global development can equally distribute education internationally.[1] Teachers Without Borders received the 2018 Luxembourg Peace Prize for Outstanding Peace Education, recognized for a free Peace Education program involving teachers from regions in conflict, for having embedded peace education into all TWB courses (see below), and its Voice of Teachers Radio Show in Nigeria.

In 2018, TWB's membership has reached 177 countries. Teachers Without Borders membership is free and enables local educators the opportunity to connect with colleagues globally.
