This chart ranks Am Law 200 firms by their pro bono score for work performed by U.S.-based lawyers. Half of the score comes from the average number of pro bono hours per lawyer in 2022; the other half represents the percentage of ­lawyers who performed more than 20 hours of pro bono work. Calculations are based on lawyer counts as of Dec. 31, 2022, which, given attorney hires, means a firm could achieve more than 100% of lawyers who achieved more than 20 hours of pro bono work in the year.

We define pro bono work as legal services donated to organizations or individuals. We do not include work done by paralegals or summer associates, nor time spent on bar association work, nor on nonlegal work for charities or nonprofits.
