My T is licensed as a supervising T. Here, you have to have several hundred hours of supervised counseling in grad school. Then, you have to take a test to become a provisional T. After that, you must have thousands of hours of supervised counseling before you are fully licensed. There is a ratio of hours spent with the supervising T v. Hour spent counseling clients. Once a T is fully licensed, I don't think that they are required to have time with a supervising T, but I think they have a duty to do so if a client is stuck or they need extra assistance. They also consult other Ts.... This is what I gather from looking up the laws/ethics where I am, anyway.
