What is the 70-20-10 learning model?
The 70-20-10 model is a framework that describes how people develop at work: roughly 70% of learning comes from hands-on experience, 20% from social learning with colleagues, and 10% from formal training. Its core message is simple: most learning happens in the flow of work, not in the classroom.
The three sources of learning
- 70% experiential learning: solving real problems, taking on new responsibilities, and learning from mistakes in daily work
- 20% social learning: feedback from managers, coaching, mentoring, and collaboration with peers
- 10% formal learning: courses, workshops, e-learning modules, and certifications
The 70-20-10 model in practice for L&D teams
The model is most useful as a design principle. Instead of putting all your energy into formal courses, design programs that activate all three sources:
- Pair a course with a real project where participants apply what they just learned
- Build in feedback loops such as manager check-ins, peer reviews, or mentoring
- Use short digital modules to cover the 10% efficiently, so more time is left for practice
Is 70-20-10 an exact formula?
No. The exact percentages have been debated, and the split varies by role and context. Treat the model as a reminder rather than a rule: development is multidimensional, and the most powerful growth usually happens beyond the classroom. If your learning strategy only covers the 10%, you are missing where most of the learning actually happens.
