Leadership Development ROI Is Real—And Proving It Is Harder

Most HR Leaders Believe Development Works. Fewer Can Show It.

Confidence Outpaces Evidence

Ask HR, and development is delivering. Three in four (76%) say their programs are designed to achieve strategic goals, and many say they’re seeing results: 68% say development has improved leadership capabilities, and 61% say it has improved business performance.

Fewer, however, can back that confidence with evidence. Only 51% say their programs provide evidence of overall effectiveness. With budgets under pressure, “we think it works” is a vulnerable position. Could HR defend its development investment to the CFO tomorrow?

Capacity is part of the problem. More than half of HR organizations (53%) say their department is too small relative to the business, leaving little time to anticipate upcoming talent needs, let alone measure impact. But time isn’t the only obstacle. Some programs aren’t designed to capture the outcomes business leaders care about. In other cases, the evidence exists but isn’t gathered or shared in a way that reaches decision-makers. Either way, the result is the same: HR is left defending its programs on belief and perception rather than data-backed proof.

Why the Business Case for Leadership Development Is Hard to Make

Even when HR has a strong case for leadership development ROI, business leaders aren’t always ready to hear it. That’s because the payoff from development isn’t always immediate, and the benefits of better leadership can be hard to isolate in a quarterly report.

Some executives still see interpersonal skills as “soft” and less valuable than technical ones, or assume leadership is something you hire for rather than build, an assumption that has never been less true than today. The business landscape keeps shifting, and the leadership profile that fit yesterday won’t meet tomorrow’s needs.

More than half of HR organizations (53%) say their department is too small relative to the business, leaving little time to anticipate upcoming talent needs, let alone measure impact. 

Past experiences with low-quality training can also leave lasting skepticism. And without a visible bench crisis, the cost of underinvesting in leaders stays hidden until a critical role opens and no one is ready to fill it.

Meanwhile, competing priorities like AI investment and headcount can look more urgent, and development spending is often seen as discretionary.

Evidence alone doesn’t always land, either. Data built on perceptions is easy to dismiss, and ROI figures take too long to calculate and often seem too good to be true, inviting skepticism. What persuades executives is a strong story: credible data brought to life by examples of individual leaders leading differently.

When Development Can’t Prove Its Value, It’s Easy to Cut

Those doubts carry more weight when budgets tighten, and right now, AI is one of the biggest competitors for investment. One recent survey of HR budget owners found that nearly half of companies (47%) increased AI spending while cutting learning and development budgets.

AI is one pressure on development budgets, but the case for development has never depended on any single trend. Organizations need a bench ready when a critical role opens: leaders who can step into bigger roles as AI absorbs the entry-level work that once built judgment and influence, and experienced leaders who keep growing as their roles and teams evolve. Change adds urgency, since leaders must build new skills quickly when the business shifts, but it’s only one reason development matters. That’s why the case for investing holds all the time, not just when disruption hits. But as budgets shift toward AI and other priorities, development without proof becomes the easiest line to cut, and that may be the most expensive mistake an organization can make: businesses only perform as well as their leaders do.

High-Quality Development Delivers

The good news: development does pay off when programs are high quality. HR leaders who rate their development programs as high quality are 2X more likely to say those programs improved business performance.  Quality programs also strengthen the bench, allowing HR to fill about 39% more critical leadership roles immediately with internal candidates. And organizations with effective development plans have 44% more high-quality leaders.

Quality also shows up in what leaders do back on the job. Leaders apply 74% of what they learn from high-quality programs, compared with 62% when programs are rated moderate quality and 52% when programs are rated low quality. In other words, high-quality development turns about three-quarters of what leaders learn into action, compared with about half when quality is low.

So what does “high quality” look like? Four elements make the difference: starting with assessment, personalizing to each leader, involving managers, and aligning to strategy. When development programs include all four, HR is 12.3X more likely to say development has improved leadership capabilities and 6.5X more likely to have evidence its programs work.

While easy reporting show that development happened, they leave unanswered the question stakeholders care about most: Is development changing how leaders lead, and is the business better for it?

Results also track with investment. Organizations that invest below average in their high-potential leaders report weaker outcomes across the board: 47% say development improved business performance, compared with more than 70% of those investing at or above average. The pattern is similar for improved leadership capabilities (59% vs. 76%). Beyond average investment, results level off.

Evidence is one outcome that keeps climbing with funding. The share of organizations with evidence that their programs work rises steadily with investment, from 38% to 51% to 63%.  The connection likely runs both ways: well-funded programs have more room to measure impact, and programs that can show impact are easier to fund.

Smile Sheets and Completion Rates Don’t Make the Case

Completion rates are among the easiest development metrics to track, and among the least persuasive evidence of leadership development ROI. When HR professionals named the outcomes that best show development value, just 2% chose completion rates, and 6% chose participant satisfaction. Far more pointed to what leaders actually do: improved leader behavior or capability was the most common choice (24%), followed by stronger team outcomes (18%), and improved business performance (16%).

Yet easy reporting metrics end up filling the reports HR shares. They show that development happened, but they leave unanswered the question stakeholders care about most: Is development changing how leaders lead, and is the business better for it?

The question isn’t whether development works. It’s whether HR can show it. 

Proof isn’t a report HR assembles after a program ends—it’s built in from the start. And proving leadership development ROI doesn’t require a perfect ROI calculation. It requires three things: agreeing up front on what success looks like, knowing where leaders started, and sharing what changed in terms the business recognizes. Most of that is planning, not extra work.

You also don’t need to measure everything at once. For stretched HR teams, start with the highest-priority program, then build from there.

1. Agree on what success looks like before a program is built.

Most HR organizations say their programs are designed to achieve strategic goals. But a goal like “build stronger leaders” is hard to prove.

Before a program launches, sit down with the business leaders who sponsor it and agree on what should change: which leader behaviors, which team results, which business metrics. That agreement turns strategic intent into outcomes everyone recognizes and gives HR a clear target to report against later.

For example, if a program aims to help frontline leaders lead change, agree up front to measure it three ways: leaders’ change-leadership skills through assessment, how their teams rate their communication about changes, and a business metric tied to the change, such as how quickly a new process is adopted.

Defining success together also builds buy-in. When business leaders help set the measures, they’re more invested in the results, and more likely to trust them.

Organizations that use assessment to diagnose leaders’ strengths and development needs are 1.8X more likely to be among the top 10% of financial performers.

2. Capture a starting point, then measure the change.

You can’t show change without knowing where leaders started. Assessment gives HR that baseline: an objective picture of leaders’ strengths and development needs before a program begins, so progress can be measured rather than assumed. Organizations that use assessment to diagnose leaders’ strengths and development needs are 1.8X more likely to be among the top 10% of financial performers.

From there, track progress during and after the program. That can mean reassessing key skills to see how leaders have grown, asking managers what their leaders are doing differently on the job, or following up on how often leaders apply what they’ve learned. Many organizations miss this step: only 49% of HR organizations say their programs provide real-time feedback on leaders’ development needs. Without it, there’s no way to adjust along the way or to show what changed by the end.

3. Report outcomes, not activity.

Completion rates and satisfaction scores show that development happened. Stakeholders want to know what it changed. Build reports around the outcomes they value most (e.g., changes in leader behavior, team outcomes, and business performance), measured against the baseline you captured and the goals you agreed on up front. Then pair the numbers with stories from individual leaders, so the results feel real.

That kind of reporting does more than justify the year’s spend; it builds the case for what’s next. When stakeholders can see how leaders are leading differently and what that means for the business, development stops looking like a discretionary expense and starts looking like an investment worth protecting.

Development has never been more necessary or more scrutinized. And this leadership development research makes one thing clear: organizations that plan for proof won’t have to fight as hard to protect development, because the results will make the case for them.
