Can you take a service-dog-in-training everywhere you can take a service dog?

The American's with Disabilities Act does not apply to service dogs in training. Some states have laws which permit trainers to take service-dogs-in-training to the same places fully trained service dogs can go. However, most states require service-dogs-in-training to be accompanied by a trainer from a recognized program for training service dogs and that they carry credentials which they show on request.
