I recently attended the TTT(Train the Trainer) certification program from Bodhih at Bangalore. It was for 4 days and definitely intensive training. The training was very interactive and all components of what a budding Trainer should know were covered. Personally, I would recommend this training to someone who wants to build up a career in Training.
I like the topics covered in the training which covers all aspects of what a trainer should do. For those having busy work schedule, please plan to put those away during the 4 days of this program.
