What is the purpose of a train-the-trainer model in seminar design?

• A. Replace expert instructors with lay leaders.
• B. Build local capacity by training trainers who then train others.
• C. Stop updating content after initial rollout.
• D. Limit training to a single campus.

Answer: (B)

The main idea being tested is how to scale learning by creating a cascade of trained facilitators. A train-the-trainer approach equips a core group of trainers who then teach others, enabling knowledge to spread more widely and sustainably. This makes the program less dependent on a single expert and more capable of reaching multiple sites and audiences while maintaining consistency in delivery and standards. It also supports ongoing growth, since trained trainers can continue to train new participants and refresh content as needed.

Why this is the best fit: it captures the goal of expanding capacity locally and over time, not just delivering a one-off session. It emphasizes building a sustainable network of trainers who can sustain and grow the program.

Why the other ideas don’t fit: replacing expert instructors with lay leaders undermines quality and expertise; the model is about empowering trainers rather than replacing specialists. stopping content updates after rollout contradicts the need for continual improvement and adaptation. limiting training to a single campus defeats scalability and broad impact.
