Since counselling is an art like singing, learning from different people at the same time may confuse you. Every counselor has his/her own style and approach. In our experience, we have seen the trainings are effective if there is only one facilitator and just 2. The students also find it easier to get along with the style/approach of the facilitators. In unavoidable circumstances like the main facilitator is not well or something, we introduce the 3rd facilitator.
