The Accidental Trainer - Why subject matter expertise isn’t enough

...And what great training actually requires

There’s a conversation most organisations are now comfortable having.
The accidental manager.

We recognise it. We talk about it openly. We’ve seen the impact of promoting high performers into leadership roles without equipping them with the skills to lead.

But there’s a parallel conversation that hasn’t quite caught up yet.
The accidental trainer.

Because across organisations right now, people are being asked to step into training roles with the same assumption:

If you’re good at your job, you’ll be good at teaching others how to do it.
It sounds logical. It’s also fundamentally flawed

The moment it becomes clear

This usually shows up in a familiar way.

The content is strong.
The trainer is credible.
The session is well prepared.

And yet, nothing really changes.

People leave knowing more, but doing very little differently.

This isn’t a criticism of the individual. In most cases, they are doing exactly what they’ve been asked to do, with the tools they’ve been given.

The issue is simpler than that.

Training is a skill in its own right. And like any skill, it has to be learned, practiced, and refined.

The rise of the accidental trainer

There’s a growing pressure on L&D and HR teams.

More internal delivery.
More subject matter experts stepping into facilitation roles.
More expectation to deliver training quickly and at scale.

It makes sense commercially. But it creates risk.

Because without the right development, organisations don’t create trainers. They create presenters.

People who can talk at a room, but not work with it.

And that distinction matters more than most realise.

Why knowledge alone doesn’t translate into impact

Most accidental trainers default to what feels safe.

Explain the model.
Walk through the steps.
Share the expertise.

It becomes a “tell” approach.
Clear. Logical. Well-intentioned.
But largely ineffective.

Because learning doesn’t come from being told. It comes from being involved.

And that requires a different capability entirely.

What great training actually looks like

At BCF, we’ve trained hundreds of trainers over the last few years.

What becomes clear very quickly is this:
The difference isn’t content.
It’s capability.

The trainers who create real impact consistently demonstrate a set of higher-level skills that go beyond subject matter expertise.

They know how to:

Read the room

Not just deliver a plan, but adapt in real time. They sense when energy drops, when resistance appears, when something hasn’t landed.

Create psychological safety

So people contribute, challenge, and engage. Without this, learning stays surface-level.

Land a message with clarity

Using structured communication like AMEN (Audience, Message, Examples, Negatives) to ensure what’s said is actually understood and remembered.

Involve rather than instruct

Shifting from telling to asking. From presenting to facilitating. From control to collaboration.

Design for impact, not just delivery

Understanding that great training starts long before the room, through structured thinking such as the TRAIN model
—Training Needs Analysis, Results, Arrange & Design, Implement, Next Steps.

This is the difference between information transfer and behaviour change.

Training is not a one-dimensional skill

One of the biggest misconceptions is that training is simply about standing at the front of the room.

In reality, it is a blend of disciplines:

• Facilitation

• Coaching

• Communication

• Emotional intelligence

• Learning design 

The best trainers move fluidly between these, depending on what the room needs.

This is why, in practice, we see delegates transform most when they are given the opportunity to practice, receive feedback, and refine their approach repeatedly, not just learn theory. 

The cost of getting it wrong

When organisations rely on accidental trainers, the impact is often subtle at first.

Sessions feel flat.
Engagement is inconsistent.
Learning doesn’t stick.

But over time, it compounds.

Training becomes something people attend, not something that changes how they work.
L&D loses credibility.
Managers disengage from development.
Investment fails to convert into capability.

And perhaps most importantly, the trainer themselves starts to lose confidence.

The shift organisations need to make

If training is now being delivered more internally—and for many organisations it is—then the question changes.

It’s no longer:
“Who knows this subject?”

It becomes:
“Who has the capability to develop others?”

And if the answer is “we’re not sure,” then that’s where the focus needs to be.

Because training skills can be learned.
They can be developed.
And when they are, the impact is significant.

What happens when you get it right

When organisations invest in developing real training capability, something changes.

Training becomes part of how the organisation communicates.

Conversations improve.
Messages land more clearly.
People feel involved, not instructed.
And crucially, learning starts to stick.

Not because the content changed.
But because the delivery did.

The bottom line

We’ve moved past the point where training can be treated as a secondary skill.

Just as we’ve recognised the risk of accidental managers, the same thinking now needs to apply to trainers.

Because standing in front of a room and creating change are two very different things.

And in a world where organisations are asking more of their internal teams than ever before, that distinction is becoming critical.
