Why Course-Based Learning Falls Short: The 70-20-10 Model and What It Means for Your L&D Strategy

Organizations spend real money on course catalogs, learning platforms, and formal training, and most of that content sits unused. Employees log in to complete required modules, then return to their work largely unchanged. The catalog grows, the completion reports look fine, and capability across the workforce stays flat.

There is a well-known explanation for this, and it has been part of the leadership development field for decades. It is called the 70-20-10 model, and it describes where professional development actually comes from. Once you understand how it works, the gap between what L&D funds and what produces growth becomes hard to ignore.

This article explains the model accurately, looks at why a course-only strategy invests in the smallest slice of development, and shows how skills-based learning makes the experiential and social parts of growth intentional rather than accidental.

What the 70-20-10 Model Actually Says

The 70-20-10 model holds that professional development breaks down roughly as follows: about 70% comes from challenging on-the-job experience, about 20% comes from learning through other people, and about 10% comes from formal training and courses.

The on-the-job 70 covers the work itself. People develop when they take on a stretch assignment, lead a project outside their comfort zone, or solve a problem they have never faced before. The social 20 covers learning from others through coaching, mentoring, feedback, and observing how colleagues operate. The formal 10 covers structured training: the course catalog, the workshop, the certification program, the e-learning module.

The framework comes from research associated with Morgan McCall, Robert Eichinger, and Michael Lombardo, who studied the development of executives at the Center for Creative Leadership. Their work surfaced a consistent pattern in how successful leaders described where their most important growth came from, and on-the-job experience dominated those accounts.

A note on precision, because the HR audience knows this model well. The exact ratios are illustrative, not a measured law of learning. McCall and his colleagues have said as much over the years, and there is legitimate debate about treating the numbers literally. What holds up is the directional insight: the large majority of development happens through experience and people, and only a small share happens through formal instruction. Treat 70-20-10 as a useful heuristic for how you allocate attention and investment, not as a precise formula.

Why a Course-Only Strategy Funds the Smallest Slice

Here is the practical consequence. If roughly 90% of development happens outside formal courses, then an L&D strategy built only on a course catalog is investing most of its budget and attention in the smallest part of how people actually grow.

The reason course-only strategies persist is that the 10 is the easiest part to buy and measure. You can purchase a content library, assign modules, and pull a completion report. The 70 and the 20 are harder. They live in the flow of work, in manager relationships, and in assignments that are not standardized. So they get left to chance.

When the experiential and social parts of development are left to chance, growth becomes uneven. Some employees land on a manager who hands them stretch work and coaches them through it. Others sit in roles where the work never changes and no one is paying attention to their development. The course catalog is the same for both, and it moves neither of them very far.

This is the disconnect that shows up in the data. LinkedIn's 2024 Workplace Learning Report found that 90% of organizations are concerned about employee retention and that providing learning opportunities is their top retention strategy. The same report found that only about one in five employees feels confident in their ability to make an internal move. Organizations are investing in learning, and employees still cannot see how that learning connects to where they want to go.

How Skills-Based Learning Makes the Full Model Work

Skills-based learning fixes the disconnect by tying development to two things: the specific skills a person needs to grow, and the on-the-job application and career goals that give those skills a purpose. Instead of pointing employees at a catalog and hoping they pick well, you connect each development activity to a named skill gap and a real path forward.

That connection is what turns the 70 and the 20 into something deliberate. A stretch assignment stops being a lucky break and becomes a planned way to build a skill the person actually needs. A coaching conversation stops being generic encouragement and becomes targeted feedback on a defined capability. Formal courses still play their part in the 10, but now they close specific gaps rather than filling a catalog.

Making the experiential and social 90% intentional requires knowing two things with precision: what skills each role needs, and where each person's gaps are. You cannot design a meaningful stretch assignment if you have not defined what the target role requires. You cannot coach toward a skill you have not named. This is why the foundation has to come first.

Start With Job Architecture, Then Build the Skills View

The starting point is job architecture: a clear definition of what each role is, how roles relate, and what skills and proficiency levels each one requires. Without that structure, skills-based learning has nothing to aim at. You are back to guessing, which is how course catalogs get filled with content nobody needs.

With job architecture in place, you can build a skills view on top of it. Defined roles let you assess where each person stands relative to what their current and target roles require. That assessment produces a real gap analysis, not a wish list. The competency models underneath each role give the assessment something concrete to measure against.

This sequence matters. Job architecture defines the targets, skills intelligence reveals the gaps, learning gets directed at those gaps, and career pathing shows the person where the work is taking them. Each layer depends on the one before it. Skip the foundation and the rest collapses back into generic training.

Where Career Bird Fits

Career Bird connects learning to specific skill gaps and career paths, which is what makes the full 70-20-10 model actionable instead of just the formal 10. The platform starts with job architecture, builds a real-time view of workforce skills on top of it, and ties learning plans to the gaps that assessment reveals.

Because the skills data connects to career paths, employees can see how a given skill maps to the role they want next. That visibility is what drives engagement. LinkedIn's 2024 research found that learners who set career goals engage with learning four times more than those who do not. When development is tied to a visible destination, people invest in it.

For managers, the same data turns coaching conversations into something specific. A manager who can see exactly where an employee's gaps sit, and which assignments would close them, can direct the experiential 70 and the social 20 on purpose. That is the difference between a manager who collects status updates and one who develops people.

Operationalizing the 70: Experience by Design

The on-the-job 70 becomes intentional when you map stretch assignments and projects to the specific skills a person is trying to build. Start from the gap, then find the work that closes it.

If an employee needs to build skill in cross-functional project leadership, the development plan should put them on a project that requires exactly that, with enough challenge to grow and enough support to succeed. The assignment is chosen because it builds a named skill, not because it happened to be available.

This is where defined roles pay off again. When you know what skills the next role requires, you can assign work that builds those skills before the promotion, so the person is ready when the role opens. Experience stops being something that happens to people and becomes something you design for them.

Operationalizing the 20: Coaching Tied to Real Gaps

The social 20 becomes intentional when manager coaching and mentoring are directed at defined development needs instead of being left to general goodwill. A manager who knows an employee's specific skill gaps can give feedback that targets those gaps directly.

Pair this with mentoring that matches the skill being built. An employee developing a capability that a colleague already has strong proficiency in benefits from a structured mentoring relationship aimed at that specific transfer. The match is deliberate because the gap is known.

These are career development conversations, the ongoing dialogue between a manager and an employee about growth and next moves. They are distinct from the structured individual development plan that documents the path, and both work better when they are grounded in real skills data. A coaching conversation backed by a clear view of gaps is more useful to both people than one built on impressions.

Operationalizing the 10: Targeted Learning That Closes Named Gaps

Formal learning earns its place when it closes a specific, identified gap rather than filling a generic catalog. The 10 is small, so it has to be precise.

Instead of buying broad access to thousands of courses and hoping employees choose well, direct learning at the gaps your assessment surfaced. An employee with a defined gap in data analysis gets the course that closes that gap, ideally right before a project where they will apply it. The course connects to the experiential 70, so the skill solidifies through use.

This approach also makes the budget defensible. When every learning investment maps to a named gap and a career path, you can explain to finance what the spend is for and what it is meant to produce. That connection is the core of a credible talent development strategy, and it is exactly what a course-completion report cannot give you.

Measure Skill Growth, Not Course Completions

The final shift is in measurement. Course completion tells you that someone finished a module. It says nothing about whether their capability changed or whether the change mattered.

Skills-based learning lets you measure what actually counts: movement in proficiency over time. When you assess skills against role requirements at regular intervals, you can see whether a development plan is closing the gaps it targeted. You can see which assignments built capability and which did not. You can connect skill growth to outcomes the business cares about, like readiness for internal moves and reduced reliance on external hiring.

This reframes the L&D conversation entirely. The question moves from "how many courses did we deliver" to "how much did capability grow, and where." That is a question your C-suite can act on, and it is the same logic that drives a connected L&D budget instead of one that funds content and hopes for outcomes.

Frequently Asked Questions

What is the 70-20-10 model?

The 70-20-10 model describes where professional development comes from: roughly 70% from challenging on-the-job experience, 20% from learning through other people such as coaching and feedback, and 10% from formal training and courses. It originated from research associated with Morgan McCall, Robert Eichinger, and Michael Lombardo at the Center for Creative Leadership.

Is the 70-20-10 model still relevant?

The directional insight holds up well: most development happens through experience and relationships, and only a small share comes from formal instruction. The exact ratios are illustrative rather than a precise law, and there is legitimate debate about treating the numbers literally. Used as a heuristic for where to direct attention and investment, the model remains a useful guide for L&D strategy.

What is skills-based learning?

Skills-based learning connects development to the specific skills a person needs and to the on-the-job application and career goals that give those skills purpose. Rather than pointing employees at a general catalog, it ties each learning activity to a named skill gap and a defined career path, which makes both formal and informal development more intentional.

Why do employees ignore course catalogs?

Employees ignore generic course catalogs because the content is not connected to their specific gaps or their career goals. When learning has no clear link to where someone wants to go or what they need to grow into, there is little reason to engage. LinkedIn's 2024 research found that learners who set career goals engage with learning four times more than those who do not.

Does formal training still matter under the 70-20-10 model?

Formal training matters, but it works best when it closes a specific, identified gap and connects to real work. A course taken in isolation produces weaker results than the same course taken right before a project where the skill gets applied. The 10 is most effective when it supports the experiential 70 rather than standing alone.

How does job architecture support skills-based learning?

Job architecture defines what each role is and what skills and proficiency levels it requires. That structure gives skills assessment a benchmark to measure against and gives development a clear target. Without defined roles, learning has nothing concrete to aim at, which is how course catalogs fill with content no one needs.
