THE SHIFT

## Training Starts Learning. Practice Builds Capability.

Organizations invest heavily in training, and they should. But knowledge only becomes capability when people apply it, get feedback, and try again. That's how expertise develops, and it's the part that usually goes unmeasured.

The organizations building skills fastest aren't creating more training. They're creating more opportunities for employees to learn from one another.

10%

Formal Training

20%

Peer Collaboration

70%

On-the-Job Tasks

Roughly 90% of L&D budget goes to the 10% that is formal training. The 90% of development that happens through real work and peer collaboration goes largely unmeasured.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-39-4743-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-39-4743-PM.png)

PEERCEPTIV RESEARCH

People learn more by giving feedback than by receiving it.

As a form of constructive learning, giving feedback requires critical thinking and analysis, whereas receiving feedback is a passive learning process.

THE PROBLEM

## Proving Level 3 and Level 4 impact is structurally hard

Yet the systems built to prove training works still assume learning happens in a classroom. U.S. organizations spend an estimated **$166 billion a year** on training, and still struggle to answer the one question every CFO eventually asks: *did it work?* The Kirkpatrick Model, the standard since 1959 for measuring training impact, shows exactly where that certainty breaks down.

L1: Reaction

 

90–94%

L2: Learning

 

60–70%

L3: Behavior

 

18–20%

L4: Results

 

7–10%

Fewer than 1 in 5 organizations reach Level 3.

Fewer than 1 in 10 reach Level 4.

**Manager time**

Observing behavior change takes time most managers don't have.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-40-9944-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-40-9944-PM.png)

**Subjectivity**

Behavioral evaluation is inconsistent across raters and prone to bias.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-42-2176-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-42-2176-PM.png)

**Lag time**

Reviews happen too infrequently to support timely decisions.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-42-9077-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-42-9077-PM.png)

**Cost**

Comprehensive behavioral assessment runs $5K–$15K per participant.

Why this matters now

Organizations are shifting toward skills-based hiring, AI-assisted work, and internal mobility. All three require trustworthy evidence of what people can actually do, not just what courses they've completed. Peer review creates that evidence as work happens. *See [Does Your Workforce Data Hold Up?](https://whitepaper.peerceptiv.com/peerceptiv-blog/does-your-workforce-data-hold-up-moving-from-claimed-skills-to-demonstrated-capability) for why claimed skills data doesn't hold up to scrutiny, and take the [Kirkpatrick Assessment](https://whitepaper.peerceptiv.com/peerceptiv-blog/most-ld-teams-cant-make-it-past-l2) to see where your own measurement stands.*

THE RESEARCH

## Why peer review works

Peerceptiv is built on more than two decades of research conducted at the University of Pittsburgh, involving **20,879 learners across 76 institutions**. Peerceptiv wasn't inspired by this research. It was built from it.

![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-4743-PM.png)

Giving feedback teaches more than getting it

The person providing feedback learns more than the person receiving it. Reviewing a colleague's work demands evaluating it, diagnosing problems, and explaining reasoning, a more durable form of learning than passively receiving critique.

**What this means:** the cognitive work of reviewing builds measurable skill in the reviewer, independent of any benefit to the person reviewed.

Yu & Schunn (2023); Wu & Schunn (2021)

![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-40-9944-PM.png)

Aggregated peer review can be as reliable as expert review

Meta-analyses find a 0.63 average correlation between peer and expert ratings, with well-designed studies reaching 0.70 to 0.91. Aggregating multiple peer reviews closely tracks expert judgment.

**What this means:** multi-peer review with structured rubrics is a credible, scalable alternative to expert review.

Xiong et al.; Cho, Schunn & Wilson (2006)

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-43-1541-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-43-1541-PM.png)

Multiple reviewers drive change more than a single expert

When the same issue is flagged by several colleagues independently, people are far more likely to act on it. Employees revising work from multi-peer feedback improved more than those coached by one expert.

**What this means:** routing each piece of work to multiple reviewers meaningfully raises the odds that feedback actually changes behavior.

Wu & Schunn (2020); Patchan, Charney & Schunn (2009)

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-41-6661-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-41-6661-PM.png)

Peer review reliably improves performance and skill development

Multiple meta-analyses confirm structured peer review produces measurable performance gains that transfer to new tasks over time, strengthening critical thinking and feedback skills.

**What this means:** peer review isn't a workaround for limited trainer capacity. It engages the whole workforce as developers of each other's capability.

Yu & Schunn (2023); Li et al. (2020, 2021); Double et al. (2020)

Twenty additional peer-reviewed studies back these findings. [See the full publications list.](https://corporate.peerceptiv.com/research/publications)

HOW PEERCEPTIV WORKS

## Work becomes practice. Practice becomes evidence.

That's exactly what Peerceptiv was designed to do: embed structured peer review into real work so organizations generate evidence of capability while employees develop it.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-42-5658-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-42-5658-PM.png)

Apply skills

Participants apply what they're learning to real work: a training exercise, a project, or their day-to-day role.

Receive peer feedback

Peers review that work and deliver structured feedback aligned to targeted skills and competencies.

Generate evidence

Organizations gain measurable data on skill growth and behavior change over time.

Scales without bottlenecks

Because the work itself becomes the assessment, Level 3 and Level 4 evidence is generated naturally instead of through a separate observation process.

THE PAYOFF

## You've been measuring the wrong part of learning

TRADITIONAL LEARNING

"Tell me what you learned."

↓

MODERN LEARNING

"Show me what you can do."

Peerceptiv operationalizes this process at enterprise scale, capturing structured evidence every time employees review one another's work.

GETTING STARTED

So where do you start?

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-38-5140-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-38-5140-PM.png)

1

Pick one program

Start where people already produce real work: onboarding, a hi-po cohort, or sales enablement.

![](https://whitepaper.peerceptiv.com/hs-fs/hubfs/undefined-Jul-28-2026-05-35-38-8562-PM.png?width=512&height=512&name=undefined-Jul-28-2026-05-35-38-8562-PM.png)

2

Define what good looks like

Build a simple rubric around skills that matter to the business.

![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-7333-PM.png)

3

Run a few review cycles

Have peers assess a handful of real tasks or deliverables. The strongest signal comes from multiple reviews, not one.

![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-43-1541-PM.png)

4

Prove it, then scale

You'll have Level 3 signal from one cohort with no new stack required. Expand from there.

The cost of getting it wrong, by program type

| Program | Cost of failure / participant | Why |
| --- | --- | --- |
| Onboarding & Early Career | $3K–$7K+ | Replacement costs reach 3–4× salary when recruiting, onboarding, and lost productivity are included. *(SHRM)* |
| High-Potential (HiPo) Programs | $5K–$15K | 60% of new managers underperform in their first two years due to poor preparation. *(DDI)* |
| Sales Development | $5K–$10K+ | Replacing a sales role costs 1.5–2× compensation, and early attrition hits revenue directly. *(The Bridge Group)* |
| Functional Upskilling | $1.5K–$5K | 40% of workers will need reskilling within three years due to AI. *(IBM)* |

Size your own exposure

Headcount × 15% early turnover × average salary × replacement multiplier (50–200% of salary, by level)  
Example: 50 early-career hires × 15% × $55K salary × 50% replacement cost = **$206,250 at risk in year one alone.**

KEY TAKEAWAYS

## What to remember

- ![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-1772-PM.png)Structured peer review has been proven, through more than 20 years of research at the University of Pittsburgh, to deepen learning for both the giver and recipient of feedback.
- ![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-1772-PM.png)Because peer review develops capability through real work, it generates Level 3 and Level 4 evidence as a natural byproduct.
- ![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-1772-PM.png)The results are real: 700% growth in active programs at a Fortune 100 insurer, 49% reduction in turnover, 90% task completion across programs.
- ![](https://whitepaper.peerceptiv.com/hubfs/undefined-Jul-28-2026-05-35-39-1772-PM.png)Getting started doesn't require a redesign. It's a layer on top of your current process.
