The composition of corporate boards has undergone significant scrutiny in recent years. Investor expectations, voluntary disclosure practices and legal requirements around board diversity and inclusion now vary significantly across jurisdictions and continue to shift, but the case for diversity and inclusion in boardrooms rests on what varied perspectives contribute to oversight and decision-making across regulatory environments.
According to What Directors Think 2026 by Diligent Institute and Corporate Board Member, 12% of directors named age diversity as a recruitment priority, while 8% named ethnic diversity and 8% named gender diversity. The survey, conducted online with more than 200 U.S. public company directors in fall 2025, reflects competing board recruitment priorities.
Directors are weighing the diversity of board members alongside pressing demands for industry, financial and technology expertise. Nominating committees should assess diversity and required expertise together when maintaining the board's succession plan.
This guide covers what board diversity and inclusion look like in practice:
Diligent's 2022 diversity review provides historical context for the advantages of diversity and inclusion in boardrooms. Diverse boards bring together individuals with different backgrounds and experiences, and these differences introduce varied perspectives that support:
Recruitment priorities are only one input into board composition planning. Boards should compare stated priorities with actual representation and future skills needs before setting recruitment goals.
Current representation data puts these priorities in context. Women held 34.4% of S&P 500 board seats in 2026 and underrepresented minorities held 24%, according to the Spencer Stuart snapshot. These figures reinforce the need for deliberate succession planning and broader candidate outreach to sustain progress on representation.
One caveat belongs in any honest discussion of the benefits of board diversity: Evidence linking board diversity with stronger financial performance is correlational. Its operational value tends to come through broader deliberation, wider market understanding and reduced groupthink, and these benefits depend on how the board actually works together.
A diverse board needs inclusive practices to be effective. Inclusion creates an environment where all board members feel comfortable sharing their unique perspectives and contributing to discussions.
In a 2024 study of senior leaders cited by Harvard Business School, 65% of women said they feel they can influence decision-making, compared with 85% of men. A board can meet every representation target while still failing to give women directors meaningful weight in its decisions. Chairs should therefore evaluate participation and influence alongside representation.
Board chairs can close that gap by using structured turn-taking so every director can speak on major agenda items. Chairs should also actively solicit dissenting views before calling a decision and visibly follow up on contributions so directors see their input change outcomes. These practices require no policy change, and each can be tested at the next meeting.
“...How do you encourage respectful dissent? Instead of asking, ‘Do we agree?’ ask ‘What’s missing?’ Start the conversation with framing statements: ‘Here’s what our goal is, and want to ensure we hear all sides of the conversation,’ framing it as info-gathering and diversity of perspectives, and that everyone’s voice is valued,” says Lori Nishiura Mackenzie, Co-Founder of the Stanford VMware Women’s Leadership Innovation Lab.
Despite the advantages, achieving true diversity and inclusion in boardrooms presents challenges that persist even when a board recognizes the value of varied perspectives. Good intentions rarely translate into representation on their own, since the mechanics of nominating candidates and running meetings can work against that goal long after directors have agreed on the principle. These obstacles tend to fall into a few recurring categories:
On the first point, restricted networks are usually the constraint; qualified candidates are available. Nominating committees that recruit only through sitting directors' personal contacts tend to reproduce the existing board's profile, whatever their intentions.
“Intentionality is important when it comes to diversity. Sometimes recruiting firms need to dig deeper in order to ensure a diverse pool of candidates,” says Emily Rollins, Board Member at Dolby Laboratories, Xometry and Science 37.
Slow turnover compounds the problem. S&P 500 boards appointed 364 new independent directors in 2026, the lowest number since 2016, per Spencer Stuart. With so few seats opening each year, every appointment carries more weight. A board that waits for a vacancy to start considering the diversity of board members has already narrowed its options.
None of these obstacles are permanent, and boards that treat diversity as an ongoing practice rather than a one-time initiative tend to see steadier progress. The strategies below split into two groups: the practices that widen who gets considered for a board seat in the first place, and the practices that keep those gains from stalling once new directors join.
Several strategies can help boards overcome these challenges and build a more diverse and inclusive environment:
These practices carry weight beyond the boardroom, too. Research by Harvard sociologists Frank Dobbin and Alexandra Kalev found that mentoring initiatives lifted representation of underrepresented groups in management by 9% to 24% over five years. Diversity task forces, which investigate where a company's pipeline breaks down and assign owners to fix it, produced gains of 9% to 30% over the same period, according to their Harvard Business Review analysis of more than 800 firms. Mandatory training and rigid hiring rules performed far worse in the same research, which suggests boards get more from structured audits and relationship-based programs than from compliance mandates alone.
Informal commitments fade once the director who championed them rotates off or attention shifts to other priorities, and boards relying on good intentions alone tend to see the same gaps resurface at the next vacancy. Four further practices turn these strategies from aspiration into measurable governance:
Record conclusions and actions in the succession plan, then revisit them as strategy changes or results fall short. Diligent's guide to board composition practices explains how these elements fit together across the annual governance cycle. The approach helps the nominating committee identify gaps, challenge assumptions and explain its decisions to investors and other stakeholders.

Recruitment and disclosure trends both moved in 2026, and boards should assess them separately. Women accounted for 29% of new S&P 500 director appointments in 2026, the lowest share since 2017, according to the Spencer Stuart snapshot. Nominating committees should use this trend to test whether succession plans and candidate pipelines are broad enough before vacancies arise.
Appointments show who joins a board; disclosure determines what investors and other stakeholders can assess. Boards should treat representation and transparency as distinct governance questions. From 2024 to 2025, the share of companies disclosing directors' race and ethnicity declined by 40% in the Russell 3000 and 32% in the S&P 500, per The Conference Board. These shifts are part of a broader board diversity reset. Companies should review their disclosure approach deliberately against investor expectations and applicable local requirements.
A weak diversity record carries a second-order risk beyond disclosure optics. “Manage the things you do have control over. Take a critical look at your board. Are they fit for purpose? Companies don’t do that, they get comfortable, ‘No one’s come knocking,’ then they have a bad year or two, they have a weak board with no diversity, and activists start looking at you. You don’t want to create low-hanging fruit for activists to target,” says Jon Solorzano, Counsel at Vinson & Elkins.
The regulatory picture behind those numbers has changed, and it looks different depending on where a company is listed.
Legal obligations now differ sharply by jurisdiction, so multinational boards need to track each market separately, and the range of outcomes shows there's no single model for turning a target into board seats.

Diversity and inclusion in boardrooms are essential elements of effective corporate governance. Boards should review composition data and board evaluation results, then update succession plans when representation or influence falls short.
Boards need reliable evidence when comparing their composition with peers and monitoring investor expectations. They also need it when preparing for proxy-season scrutiny. Diligent Market Intelligence provides real-time insights into shareholder activism and proxy voting. It also tracks market behavior so governance teams can replace assumptions with market data.
How boards use these capabilities varies with a company's stage:
Across all three stages, custom dashboards and expert support can organize the evidence around the questions a specific board asks. Governance teams can bring historical voting records and governance benchmarks into one view, then add current activism alerts. This allows them to test a board composition narrative against observable market behavior rather than assumptions.
Diligent Market Intelligence supplies market evidence for governance decisions. Candidate selection, diversity outcomes and legal compliance remain the responsibility of the board and its advisers.

Board diversity covers the board's full profile. It includes demographic characteristics such as gender, race, ethnicity and age, along with differences in skills, professional backgrounds, industry knowledge and problem-solving approaches. Effective boards assess both dimensions so their combined experience and perspectives match the company's strategy and reduce oversight blind spots.
A board diversity policy should define its scope and objectives. It should explain what diversity means and set candidate-pool expectations. Responsibility should be assigned to the nominating committee. The policy should also explain how progress will be assessed and how often reviews will occur. It should address voluntary disclosure. The appropriate content depends on the company's jurisdiction. Ownership structure and strategy also shape it.
Use board evaluations to ask directors about participation and their ability to influence decisions. Review the distribution of committee leadership, keep the skills matrix current and look for evidence that dissenting views affect deliberations. Together, these measures show whether directors have meaningful influence beyond their presence in the room.
Demographic diversity describes who is represented through characteristics such as gender, race, ethnicity, age and nationality. Cognitive diversity concerns differences in experience, professional knowledge, functional expertise and problem-solving approaches. Strong boards recruit for both because varied representation can broaden thinking, while each dimension still requires deliberate assessment.
Requirements depend on the jurisdiction. U.S. courts vacated Nasdaq's rules and found California's SB 826 and AB 979 unconstitutional, with enforcement enjoined, per Troy Gould, though appeals continue. EU Directive 2022/2381 remains in force with a June 30, 2026 deadline. Organizations should obtain jurisdiction-specific legal advice.
