I think no. A regulation would generate a limitation for the creative development of the training activity.

I think that the training institutions should have qualified teachers on their staff, with a master's degree and the public should demand the academic levels of their trainers.

I am always a little wary of recommending QA procedures and the very nature of education makes measuring quality extremely tricky but surely there must be some checks on quality and consistency. Whilst a binary yes/no inspection or even a ranked inspection, is likely to be overly simplistic, I would suggest a narrative based inspection which describes the provision and makes broad conclusions, would be helpful when selecting a provider and also looking at the success of it.

Dear Carla,

for sure, yes, since the science of training is a) not new (best practices in instructional design are 50 years old and b) no rocket science (there are evidenced-based evaluation models available). Bad trainings are a terrible waste of work and lifetime as well as other resources. We have developed and implemented leadership trainings in big German companies and we would have been crucified in case of bad designs, poor training outcomes and the like. Salas and Stagl (2012) give a good overview concerning state-of-the-art approaches. Kraiger is another famous scholar in this field, a quick research will reveal several wonderful articles by him.

Merry X-Mas!
