SAN FRANCISCO--(BUSINESS WIRE)--Diversity Lab is proud to announce that more law firms have committed to the Mansfield Certification process than at any point in its history. Nearly all of the firms seeking Mansfield Certification in 2023–24 have renewed their commitment and 19 new firms have joined for the next 2024–25 period, which runs from July 2024 to July 2025. Mansfield is now 365+ firms strong, an indication that the legal profession remains dedicated to its values and commitment to fair and inclusive talent practices.
Mansfield is a year-long structured certification process designed to ensure all qualified talent at participating law firms has a transparent, fair, and equal opportunity to be considered for advancement into leadership. The focus is on opening the door wider and ensuring that opportunities for advancement are inclusive for everyone. Mansfield broadens and expands opportunities; it doesn’t limit or decrease them.
Mansfield launched in 2017 with nearly 35 firms. Today, almost all of these inaugural firms are continuing to pursue certification, even as the parameters and requirements grow increasingly more challenging to implement. Data shows that firms that stay committed and accountable to the Mansfield Certification process year-over-year are making substantial progress in diversifying their leadership.
“White & Case was one of the first firms to adopt Mansfield’s principles in 2017. We remain committed to the principles because a transparent and equitable approach to creating leadership opportunities for everyone benefits our talent and our clients and is an important contributor to our success,” said Heather McDevitt, Chair at White & Case.
Each year, firms are asked to recommit to the principles of transparency, accountability, and knowledge sharing that are required through the certification process. Mansfield supports participating firms by providing the structure and guidance needed to build and maintain transparent processes, open the door wider for all talent, and connect and collaborate with each other to exchange best practices.
This year-over-year commitment to Mansfield is evident in the 2024–25 Certification cohort:
- 99% of large US and Canadian firms renewed from the prior Certification period, and three new firms joined;
- 93% of midsize US and Canadian firms renewed, and 14 new firms joined; and
- 100% of UK firms renewed, and two new firms joined.
Many of the industry’s most prominent law firms are represented in the 365+ firms participating in the 2024–25 Mansfield Certification period, including 83% of the Am Law 100.
To maintain its effectiveness at diversifying leadership over time, the standards for Certification continue to evolve based on data-backed insights. This year, 110 of the 365+ participating firms have expressed interest in piloting potential future additions to Mansfield’s parameters. The Next Gen Pilot asks firms to implement additional tracking and leadership pathway elements — including client credit recognition and relationship partner succession planning — designed to ensure all lawyers have fair and equal opportunities. The goal is to apply lessons learned from the pilot to future iterations of Mansfield.
“We are experiencing firsthand that law firm leaders don’t just say they value DEI, they are taking measurable actions to ensure leadership opportunities are more inclusive. They are opening the door wider,” said Alyssa Jarvis, Director of Mansfield & Strategic Innovations at Diversity Lab.
“We are proud to be part of the growing list of law firms demonstrating their commitment to inclusivity and talent retention through actions that have a proven track record. Adopting Mansfield reflects Sidley’s confidence in our Built to Win programs developed to ensure our attorneys have the opportunity for success and advancement that our clients expect from us,” said Yvette Ostolaza, Sidley’s Management Committee Chair.
Mike Schmidtberger, Sidley’s Executive Committee Chair, added, “We share the Mansfield Certification goal of ensuring fair and equal opportunity for all lawyers. It aligns with Sidley’s mission to attract outstanding lawyers who reflect the global marketplace and the communities that we serve, and to help them reach their full potential.”
The US, Canada, and UK large and midsize law firms seeking Mansfield Certification in 2024–25 are listed below. Firms from this group that achieve Certification after the rigorous year-long process will be announced in Fall 2025. (Please note: Firms participating in the 2023-24 cohort that recently achieved Certification will be announced in September/October 2024.)
