The Amgen Foundation announced Oct. 12 that it would donate $3 million over three years to Mountain View-based digital education nonprofit Khan Academy.

The foundation has previously provided funding to support the production of biology content for the Academy’s lessons, including new videos, articles and exercises for ninth-graders. More than 1 million students per month access the free online content, the two said in a news release.

“The Amgen Foundation’s funding allows Khan Academy to create new biology lessons that will enrich the classroom experience for students and teachers everywhere,” said CEO Sal Khan.

A 2015 grant from the Thousand Oaks-based biotech giant helped create the Advanced Placement biology course. Since it was established in 1991, the foundation has donated around $250 million to support science education and community investment.
