Mansfield Certification

Mansfield Certification ensures a fair and equal opportunity for all lawyers to advance into leadership.

Mansfield focuses on equal treatment, equal opportunity, and equal access.

The Mansfield Difference

The Mansfield Rule was inspired by a winning idea at Diversity Lab’s 2016 Women in Law Hackathon.

Mansfield is a structured certification process designed to ensure all talent at participating law firms and legal departments has a fair and equal opportunity to advance into leadership. This science-backed and data-driven inclusive sourcing process helps boost inclusivity, equal access, and transparency in advancement processes and leadership roles at participating organizations. To maintain its effectiveness, the certification standards continue to evolve year-over-year based on data-backed insights.

Mansfield is an inclusive sourcing process, not a diverse slate policy. Mansfield asks organizations to track and measure more than a dozen leadership roles and activities across an entire year and ask themselves: “Across all of these opportunities, did we consider at least 30*% qualified underrepresented talent – out of the unlimited number of people considered – before determining the final slate or making a selection or promotion decision?” Mansfield doesn’t dictate that 30% underrepresented talent be slated or selected for any given leadership role or activity, nor does it result in any person being excluded from consideration based on race or gender.

Mansfield is legal and an important equal opportunity measure because it:

  • Focuses on Consideration, Not Slates or Selection Outcomes: Mansfield focuses on opening the door wider and broadening the pool of qualified talent considered for all leadership roles and activities. Mansfield operates at the top of the talent sourcing funnel, often called “inclusive sourcing.” Mansfield only asks that qualified talent be considered, not slated or selected. Employment and advancement decisions remain outside of the scope of Mansfield and are based solely on merit, as the recent Executive Orders counsel.
  • Roots Out Discrimination by Expanding, Not Restricting, Opportunities: Mansfield doesn’t limit the number of talented individuals considered. Instead, it’s additive – it asks that all qualified talent, regardless of background, have a fair and equal chance to be considered based on excellence and merits. There are no set-asides or quotas. It’s not a “zero-sum” situation where opportunities are given to some and taken from others (which is what Chief Justice Roberts warned against in the Fair Admissions ruling on affirmative action in higher education).
  • Measures the Aggregate Pipeline to Leadership, Not One Role: Mansfield asks organizations to track and measure the pipeline to over a dozen roles and activities throughout the year, in the aggregate, to assess the overall health of the talent pool. Organizations can still certify even if they do not consider at least 30% qualified underrepresented talent for all or certain roles and activities. Mansfield does not, explicitly or implicitly, encourage employers or their decision-makers to make any selection or employment decision because of a demographic trait.
  • Writes the Unwritten Rules: Mansfield asks organizations to make all advancement processes and practices transparent and accessible to ensure everyone is aware of how pathways to leadership decisions are determined.
Note: *Consideration is 30% for law firms and 50% for legal departments.

Purpose

Mansfield helps ensure that all talent has an equal opportunity to advance into leadership through transparency and an intentional fairness-based decision-making process informed by behavioral science.

Process

Mansfield increases transparency and intentionality around law firm and legal department leadership and advancement processes. This openness benefits everyone.

Firms and legal departments commit to expanding their talent pools for all leadership opportunities.

Step 1

To achieve Mansfield Certification, law firms and legal departments increase transparency and clarity regarding opportunities. They articulate and internally publish job descriptions, expectations, and promotional paths. This greater transparency helps level the playing field for all.

Step 2

Firms and legal departments engage in Knowledge Sharing throughout the certification process, a crucial part of Mansfield. Research shows that working in a group is a better way to stay on track toward a larger goal because it creates peer group and third-party accountability.

Step 3

Firms and legal departments complete a series of check-ins with Diversity Lab to ensure they are on track to achieve Certification.

Step 4

At the end of the Certification period, firms and legal departments are required to submit an online Certification form that is signed by their managing partner or general counsel.

Step 5

As the Certification period ends, a new one begins. Firms and legal departments renew their participation in Mansfield year-over-year to ensure long-term fairness and inclusive cultures at their organizations.
