What's the best method to assess learning in skill-based courses, especially soft skills? Thanks.

The best method is Training and development or "learning and development" as many refer to it now  is one of the most important aspects of our lives and our work. (Many people view "training" as an activity that produces the result or outcome of "learning" and learning is typically viewed as new knowledge, skills and competencies or abilities.) In our culture, we highly value learning.

Knowing what you want and be presistant in you effort.

Experience and hard work on yourself.

Good Team work, Training to subordinates, building good atmoshpere
