In October 2014, Tang gave an additional $15 million to establish the Tang Institute at Andover. "A physical and virtual hub for entrepreneurial exploration, the Tang Institute at Andover supports community ideas for innovative approaches to teaching and learning. Focused on the Andover experience and advances in secondary education more broadly, the Institute encourages experimentation, interdisciplinary collaboration, new partnerships, connected learning, and ongoing assessment. By harnessing the intellectual curiosity and creativity of faculty and students—both in and out of the classroom—the Tang Institute seeks to have a lasting impact on campus and beyond."
