Midsize Mansfield Rule
Mansfield Rule for Midsize Law Firms Continues Boosting Diversity in Law
First Cohort of 26 Midsize Firms Announced as Mansfield Rule Certified
In late 2020, Diversity Lab launched a new iteration of the Mansfield Rule developed for firms with between 25 and 150 lawyers in the U.S. and Canada. The Midsize Mansfield Rule certification process, modeled after the original large-firm version, has been fine-tuned to boost diversity in leadership for firms with smaller lawyer populations, fewer office locations, and leaner firm leadership structures.
Similar to the large law firm version, firms that successfully complete the Midsize Mansfield Rule criteria will be designated as “Mansfield Certified” and will have the opportunity to send their newly promoted historically underrepresented partners to the Mansfield Rule Client Forums to build relationships with and learn from Diversity Lab’s in-house counsel collaborators. To date, more than 80 legal departments have contributed to or hosted Client Forums, including Bloomberg L.P., Fannie Mae, Ford Motor Co., Gap Inc., Google, MassMutual, McDonald’s Corporation, Netflix, PayPal, Pfizer, Starbucks, Takeda Pharmaceuticals, Transamerica, Uber Technologies Inc., ViacomCBS, and Walgreen Co.
May 5, 2022 Update: Diversity Lab is proud to announce that 26 midsize law firms (listed below) have achieved the inaugural Midsize Mansfield Rule Certification. Please read our press release here.

The Midsize Mansfield Rule Goal
The overall goal of the Midsize Mansfield Rule is to increase the representation of diverse lawyers in leadership by broadening the pool of women, LGBTQ+ lawyers, lawyers with disabilities, and/or racial/ethnic minority lawyers who are considered for entry-level and lateral attorney job openings, leadership opportunities, equity partner promotions, and opportunities to connect with clients.
How It Works
To be Mansfield Certified for 2022-2023, firms are asked to consider at least 30% historically underrepresented lawyers for 60% or more of the leadership roles and activities identified below.
- All lawyer hiring searches/openings (partners and non-seasonal associates at all levels)
- Equity partner promotions
- Election or appointment to Managing Partner/Chairperson
- Election or appointment to other high-level firm governance positions, including:
- Management/Executive Committee and/or Board of Directors
- Practice Group Leader and/or Office Head
- Partner Promotions/Nominations Committee
- Compensation Committee
- Participation in formal client pitches and formal client business meetings
- Senior professional staff hiring and promotions
- Transparent job responsibilities for governance roles
- Transparent processes for governance appointments/elections
Midsize firms pursuing Mansfield Certification Plus must not only consider but achieve 30% representation of underrepresented lawyers in at least 60% of the above tracking categories.
