What the market numbers mean for buyers
A market projected to grow at 12.6% a year through 2030 has many providers entering it. For a buyer, that means more choice and more variation in quality. Apply the same criteria to every firm on your list rather than relying on size or visibility.
What the research numbers mean for program design
The systematic review on PMC found most studied training was a single session, randomized designs were uncommon (13%), and over 70% of studies had majority female participants. That limits how far the evidence generalizes. It supports a practical conclusion: favor sustained work tied to leadership decisions and systems, and measure your own outcomes rather than assuming a session worked.

Common questions
See all questions in the FAQIs a one-time DEI training session enough?
Usually not on its own. A systematic review published on PMC found that the majority of studies (75% of antiracism training; 66.6% of DEI training) used a one-time session, and randomized designs were uncommon (13%). That limits what the research can show. Pair any session with changes to the decisions and systems leaders control.
What does research say about DEI training effectiveness?
The research base has limits. A systematic review on PMC reported that randomized designs were uncommon (13%) and over 70% of studies had majority female participants, and most training studied was one-time. That is a reason to favor sustained, decision-focused work and to measure your own outcomes.
How do we measure whether DEI consulting worked?
Measure outcomes, not just activity. Look at who receives opportunities, promotions, stretch assignments and sponsorship, and whether people feel able to contribute and use their voices. Attendance and satisfaction scores show reach, not change. Agree on measures with your consultant before work begins.
Is there a list of top DEI consulting firms?
Several sites publish lists of top DEI consulting firms, including Hacking the Case Interview’s 2026 ranking. Lists are a starting point, not a decision. Use them to build a long list, then compare each option on the same criteria: inside experience, systems focus, formats offered, framework and references. Our methodology page shows the criteria this guide uses.
Why isn’t our DEI program working?
A common reason is that programs focus on what individuals should do differently while the systems around them stay the same. Look at policies, access to opportunity, leadership decisions and unwritten norms. Also check whether outcomes are tracked, since the Accountability element of the Equity in Action Model asks leaders to look beyond intentions.
