3.0 Certified Law Firms & Results
Now in its third iteration, the Mansfield Rule Certification measures whether law firms have affirmatively considered at least 30 percent women, attorneys of color, LGBTQ+ and lawyers with disabilities for leadership and governance roles, equity partner promotions, formal client pitch opportunities, and senior lateral positions.
The goal of the Mansfield Rule is to boost the representation of diverse lawyers in law firm leadership by broadening the pool of candidates considered for these opportunities. And it’s succeeding at its intended purpose. As the certification data analyses and highlights below reveal, participating firms are moving the needle forward. See the recent press release here.
Firms are audited bi-annually and certified annually as they follow, comply, and achieve the Rules’ requirements.
Notable Outcomes
Some of the key outcomes for firms that have participated in all three certification years include:
- 96% of firms said that after adopting the Mansfield Rule, their teams of lawyers participating in formal pitch meetings have become more diverse.
- 65% of firms reported that more underrepresented lawyers were appointed or elected to their Management/Executive Committee than prior to adopting Mansfield.
- 63% of firms said they have increased the percentage of underrepresented lawyers promoted into equity partnership since adopting Mansfield.
- 58% of firms reported that their lateral partner hiring pool was more diverse following the adoption of Mansfield.
In analyzing all firms’ year-over-year progress from 2.0 to 3.0, some of the outcomes include:
- 66% of firms reported a higher percentage of diverse attorneys participating in formal pitches.
- 55% of firms reported a higher percentage of diverse attorneys elected or appointed to their Management/Executive Committee.
- 53% of firms increased the percentage of underrepresented lawyers in Office Head positions.
- 50% of firms promoted a higher percentage of diverse lawyers into equity partnership.
With transparency and accountability as the foundation of this effort, many of the firms that have participated since the Mansfield Rule’s inception in 2017 have publicly announced their individual results, which can be found here.
As further evidence of the Mansfield Rule’s success, several of the certified firms listed below have also achieved Mansfield Certification Plus. “Plus” status indicates that, in addition to meeting or exceeding the baseline certification requirements, the firms have successfully reached at least 30 percent diverse lawyer representation in a notable number of their current leadership roles.
