Mark Zuckerberg and his wife, Priscilla Chan, opened a free school for low-income families in California’s Bay Area, where Meta is headquartered.

A pair of tuition-free schools started by the Chan Zuckerberg Initiative will close at the end of this school year. The Primary School, which operates both locations, did not give a reason for the closure.

Founded in 2016 by the Chan Zuckerberg Initiative, the tuition-free private school serves students from predominantly low-income communities in East Palo Alto and neighboring Menlo Park.
