EXPLO is a non-profit organization offering personalized academic enrichment 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 8-10, and EXPLO Pre-College + Career for grades 10-12.

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