In 2010, the William and Flora Hewlett Foundation, Bill & Melinda Gates Foundation, the David and Lucile Packard Foundation and Gordon and Betty Moore Foundation collaborated to develop a comprehensive training program on legal issues in grantmaking. Out of the collaboration came Learn Foundation Law, a series of free, online trainings on legal issues that private foundation staff and their grantees must understand. The series is designed to speak to a variety of learning styles and organizational training needs.
