What is the 70-20-10 model commonly used for?

• A. 70% classroom, 20% e-learning, 10% simulations.
• B. Allocating time: 70% meetings, 20% emails, 10% projects.
• C. Guiding development investments: 70% on-the-job, 20% coaching/mentoring, 10% formal training.
• D. Allocating 70% of budget to technology, 20% to compliance, 10% to travel.

Answer: (C)

The model shows where learning really comes from in developing new skills. It says most growth happens through on-the-job experiences and applying what you know in real work, supported by coaching or mentoring, with formal training providing a smaller, supplementary boost. This is why describing development as primarily on-the-job, with coaching/mentoring as a significant second piece and formal training as a smaller third piece matches the model best. In practice, you’d focus on give-and-take work assignments, feedback from a mentor or coach, and targeted training to fill gaps. The other options talk about how time, budget, or delivery methods are allocated, not the source of learning itself, so they don’t reflect the model’s intent.
