The Assumption That's Quietly Undermining Your Training Programs
In organizations of all shapes and sizes, there's a hiring pattern that plays out constantly: a top-performing employee or a recognized industry expert is tapped to lead a training session. After all, who better to teach a skill than the person who has mastered it? It sounds logical. It even sounds efficient. But this assumption — that expertise in a role automatically translates into the ability to teach that role — is one of the most persistent and costly mistakes in corporate learning and development today.
Subject matter experts, or SMEs, are invaluable assets. They hold deep technical knowledge, real-world experience, and hard-won insights that no textbook can replicate. But knowing how to do something and knowing how to transfer that knowledge to others are two fundamentally different competencies. Organizations that fail to recognize this distinction end up with training programs that feel informative on the surface but fail to build genuine, lasting capability in learners.
What Makes a Subject Matter Expert Valuable — and What Doesn't
A subject matter expert brings credibility, depth, and authenticity to any learning environment. When an SME speaks, learners often pay close attention because they know they're hearing from someone who has actually lived the work. This is genuinely powerful and should not be underestimated.
However, expertise creates a well-documented cognitive phenomenon known as the "curse of knowledge." Once we deeply understand something, it becomes increasingly difficult to remember what it was like not to understand it. SMEs often unconsciously skip foundational steps, use jargon without explanation, and structure content in a way that makes sense to an expert but creates confusion for a beginner. They may also default to information dumping — presenting everything they know rather than focusing on what learners actually need to be able to do.
The result is training that is dense, fast-paced, and difficult to retain. Participants leave sessions feeling overwhelmed rather than empowered, and organizations are left wondering why performance metrics aren't improving despite the investment in training.
The Missing Piece: Instructional Design and Facilitation Skills
This is where instructional design and facilitation come in — and where many organizations fall short. Instructional design is the science and art of creating learning experiences that move people from where they are to where they need to be. It involves analyzing the audience, defining clear learning objectives, sequencing content logically, designing practice activities, and building in feedback mechanisms that reinforce retention.
Facilitation, meanwhile, is the skill of guiding a group through a learning experience in a way that draws out understanding rather than simply pouring information in. A skilled facilitator knows when to ask questions rather than give answers, how to manage group dynamics, how to read the room, and how to ensure every learner stays engaged and connected to the material.
Neither of these skills is automatically present in an SME. They must be deliberately developed, supported, and practiced. Yet most organizations deploy their subject matter experts into training rooms or virtual classrooms with little more than a slide deck and an expectation that their expertise will carry the day.
Why Organizations Keep Making This Mistake
It's worth asking why this gap persists so stubbornly. A few factors tend to drive it. First, there is a genuine shortage of dedicated instructional designers in many organizations, particularly in small and mid-sized companies where learning and development functions are lean. Second, asking an SME to deliver training feels like a low-cost solution — they're already on the payroll, and their availability seems like an obvious resource to leverage. Third, there's often an implicit belief that content is the heart of training, and if the content is good, the learning will follow.
But this underestimates how much delivery, design, and learner engagement shape outcomes. Research in cognitive science consistently shows that how information is presented matters as much as the information itself. Spaced repetition, retrieval practice, emotional engagement, and real-world application all significantly affect whether training produces a behavior change or simply fills a calendar slot.
How to Better Support SMEs in a Training Role
The goal is not to sideline subject matter experts — quite the opposite. The goal is to unlock their full potential by surrounding them with the support structure they need to be truly effective educators. Here are several practical approaches organizations can take.
- Pair SMEs with instructional designers. Rather than expecting SMEs to build and deliver training alone, create a partnership model where an instructional designer shapes the structure, learning objectives, and activities while the SME contributes the content expertise. This collaboration produces far stronger outcomes than either could achieve independently.
- Provide facilitation training. Offer SMEs a focused development program in facilitation fundamentals — how to ask powerful questions, how to encourage participation, how to manage pacing and energy, and how to give effective feedback in the moment.
- Focus on learning objectives, not content coverage. Coach SMEs to start by asking "What do I need learners to be able to do after this session?" rather than "What do I need to cover?" This simple reframe shifts the entire orientation of the training from information delivery to capability building.
- Build in practice and application. Work with SMEs to design activities, case studies, role plays, or simulations that give learners the opportunity to practice and apply new knowledge in a safe environment before taking it into the real world.
- Create feedback loops. Establish a process for SMEs to receive structured feedback on their training delivery so they can continue to grow as educators over time.
Building a Culture That Values Learning Expertise Alongside Content Expertise
Ultimately, the shift that needs to happen is cultural. Organizations need to recognize that teaching is a professional skill in its own right — one that deserves investment, development, and respect. Subject matter expertise is the raw material of great training, but it is not the training itself. When organizations begin to value learning design and facilitation as distinct and critical competencies, they stop wasting their SMEs' knowledge on poorly designed experiences and start building programs that genuinely change how people perform.
The gap between knowing and teaching is real. Bridging it requires intention, investment, and a willingness to rethink how organizations develop and deploy their internal talent. SMEs deserve the tools to succeed as trainers — and learners deserve training that actually works.
