The American Opportunity Index, rating America's 250 largest public companies on how they help their workers get ahead, was released Thursday.
Driving the news: The yearlong project, which included economists and data scientists, is a collaboration of The Burning Glass Institute, Harvard Business School’s Managing the Future of Work Project and Howard Schultz's Schultz Family Foundation.
How it works: The economic-mobility index rates the companies "on real-world outcomes of their employees in roles open to non-college graduates — not merely their statements on corporate policy."
The scorecard draws on "a new source of insight: big-data analysis of career histories, job postings, and salary sources of more than 3 million workers at those firms."
