EXPLO is a non-profit organization offering personalized academic enrichment summer programs where smart, curious students in grades 4-12 step outside of their comfort zones, grasp the power of their potential, and embrace their ability to shape the future. We offer EXPLO Junior for grades 4-7, EXPLO Senior for grades 8-9, and EXPLO Pre-College for grades 10-12.

With our MIT heritage and global network of alumni, EXPLO is not your average summer youth program - and it just might be the right fit for your far-from average family.
