Dear Nidhi,
I beg to differ with Anuradha. What matters is the trainer's ability to increase revenue. Everything else is secondary.
I have come across trainers who are very poor in the parameters mentioned by Anuradha, but because of their training, business increased. So what is important to you - revenue or body language of the trainer, please decide.
Newcomers concentrate on secondary aspects leaving aside business aspects. There were situations wherein all the participants gave "Excellent" feedback on all the parameters of the feedback form. But hardly their training could add any rupee to the balance sheet because there was no change in methods of operations after the training.
Please remember the good old proverb - "a talking parrot flies little".
The effects of training depend on many factors - your management, organization culture, HR/Training Department's interest, Competence of HR/Training personnel, interest of the participants, and finally the trainer.
Competence of the HR/Training personnel matters a lot to succeed in training and not the trainer's ability. I have come across HR/Training Directors who could not do Training Needs Analysis (TNA) of their organization. How many HR/Training personnel are competent to formulate objectives of a training program without taking help from Google?
