How does your organisation invest in learning?
Can you honestly say it aligns with where and how learning actually happens?
According to research from CIPD, peer collaboration usage shifted from around 30% to 36% between 2021 and 2024. The modern workplace runs on your employees’ ability to teach one another. This kind of knowledge-sharing has a name, and a clear set of characteristics that separate it from casual conversation.
What is peer-to-peer learning?
Peer-to-peer learning is what happens when employees learn from each other rather than from a formal training programme. It can take many forms – whether that’s a mentoring conversation, a debrief after a project, or a colleague walking someone through a process they’ve just figured out for themselves.
What distinguishes it from informal chat is intent. Peer-to-peer learning should always be purposeful; it draws on the knowledge and experience that already exists within your workforce and makes it accessible to others, with the express purpose of helping people grow in their roles. What’s more, it does it far faster and more contextually than most formal training can.
It's also how a significant portion of workplace learning already happens, with or without L&D's involvement.
The question for most organisations is whether they're doing anything to support it.
The case for peer-to-peer learning
Peer-to-peer learning is needed more urgently than ever. According to LinkedIn’s 2025 Workplace Learning Report, nearly half of L&D professionals say their organisation has a skills crisis, with 49% agreeing that executives don’t have the right skills to execute business strategy.
It’s a sobering stat, and it demonstrates something important: Formal training programmes aren’t enough on their own, and the impact isn’t just financial. While these programmes certainly make a dent in the organisation’s budget, the main problem is actually speed. Think about how long it takes to formulate, build, execute and pay for training. Meanwhile, the head of the department has already passed down years of knowledge to the new hire in the space of an hour.
This is where peer-to-peer learning earns its place. It turns the people already doing the work into the people who teach it, so the knowledge stays current by default.
There's no content to refresh or course to redesign when the process changes next quarter. The expertise updates itself organically, because it lives in the people using it.
The benefits: What peer-to-peer learning delivers
The benefits of peer-to-peer learning are virtually endless, but there are some distinct areas where it really shines.
Knowledge retention
We’ve known that peer-to-peer learning benefits knowledge retention for decades. In fact, the pedagogy that popularised it has been around as long as The Simpsons and light-wash jeans. Back in 1991, a Harvard physics professor named Eric Mazur coined this concept after noticing a gap between what he perceived his students to have learned and their actual conceptual understanding of a given topic.
"I thought I was a good teacher until I discovered my students were just memorizing information rather than learning to understand the material."
– Eric Mazur
After one lecture where his careful instruction seemed to land on deaf ears, he tried something different: He told the class to discuss the problem with each other instead. The room erupted into chaotic, enthusiastic conversation and within minutes, the students had worked out the answer on their own.
This is where the seed of Peer Instruction was planted, and it’s still growing.
A 2020 study published in Cognitive Research: Principles and Implications found that when students discussed answers with a peer before finalising them, accuracy improved significantly – with incorrect answers switching to correct far more often than the reverse – because discussion prompted students to retrieve knowledge, test its coherence, and fill gaps they couldn't identify alone.
Although this concept was born in a lecture hall, its principles translate directly to the workplace. The same discussion-based retrieval that helped Mazur's students hold onto physics concepts is what makes onboarding actually stick, or helps a team retain the details of a new process months after their training is over.
In practice, workplace peer-to-peer learning takes shape through structured peer coaching, cross-team knowledge shares, mentoring pairings, and informal shadowing on live projects.
What connects these settings to Mazur's classroom is the same underlying mechanism: Explaining a concept to someone else forces the explainer to test their own understanding and reinforce the correct version in memory. For the person on the receiving end, hearing that explanation in their peer’s own words carries a different kind of weight.
Faster, more relevant skills development
Peer knowledge benefits from being immediate and context-specific. If your people have a problem, they can either turn to a learning resource that was built 18 months ago, or a colleague who just solved the same problem last week. Which would you choose?
Technology can be a brilliant bolster for this, and is where mentor-matching really shines. It connects people who need a specific skill with those who already have it, thereby cutting out the guesswork of finding the right person to ask. This matters particularly for fast-moving areas like AI adoption, where most employees prefer to learn from peers by practising skills in applied settings rather than from instructors in traditional settings.
Rather than waiting for a course to catch up with a new tool or workflow, employees use social learning to pick up capability from someone already using it, in the flow of the work itself. That's the advantage a mentoring programme is built to capture: turning scattered pockets of applied knowledge into something the wider organisation can actually draw on.
Engagement and belonging
Employees who feel invested in by the people around them are more likely to feel invested in their work.
This matters at a moment when global employee engagement has fallen to 21%, costing the global economy an estimated $438 billion in lost productivity. Much of that decline traces back to a breakdown in the relationships that make people feel seen at work, rather than a lack of formal development options. Peer learning rebuilds exactly that kind of relationship.
Every mentoring conversation or shared problem-solving session is also a small act of belonging, reminding employees that their growth matters to someone else in the organisation.
Scalability
It's no secret that L&D teams are stretched.
Peer learning offers a practical way to relieve some of that burden. Rather than routing every development need through a small central team, peer learning distributes the load across the organisation, turning subject-matter experts into development assets.
Knowledge that once lived in one person's head becomes accessible across the organisation. A specialist who's spent years solving a particular class of problem can pass that expertise on directly, without L&D having to formalise it into a course first.
This matters most in fast-changing areas where formal content struggles to keep pace, letting the organisation's own expertise circulate as quickly as the problems that require it.
Making peer-to-peer learning work
So how do you successfully roll out peer-to-peer learning?
It’s more complex than simply telling your people to talk to each other. If you leave peer learning completely unstructured, you likely won’t see the benefits we’ve outlined. The difference between peer learning that works and peer learning that fizzles out is intentionality. Focus on the following three areas, and you’re more likely to see results:
- Clear goals and the skills needed to reach them
- Smart matching
- Infrastructure
Platforms like Thrive bring peer-to-peer learning into a structured environment through features like Spaces and Mentoring.

FAQs
What is peer-to-peer learning?
Peer-to-peer learning is the process of employees learning from each other rather than through a formal training programme. It includes mentoring conversations, project debriefs, and colleagues sharing knowledge they've picked up on the job.
How is peer-to-peer learning different from informal conversation?
Peer-to-peer learning is purposeful. It draws on knowledge that already exists within an organisation's workforce and makes it accessible to others, with the specific aim of helping people develop in their roles.
What are the main benefits of peer-to-peer learning?
Organisations that adopt peer-to-peer learning typically see improvements in knowledge retention, faster and more relevant skills development, stronger engagement and belonging, and greater scalability for stretched L&D teams. It also supports inclusion by creating development pathways that don't depend on a single line manager.
Does peer-to-peer learning replace formal training?
Peer-to-peer learning works alongside formal training rather than replacing it. Formal programmes provide structured foundations, while peer learning keeps knowledge current and accessible as workplace processes and tools evolve.
How can organisations support peer-to-peer learning effectively?
Effective peer-to-peer learning requires intentional support rather than being left to happen on its own. Platforms such as Thrive help organisations structure this through features like Spaces and mentor-matching, connecting employees with the right people and giving development a clear framework.
