My therapist says on her website that she has 20 years of experience. She has only been licensed for 15 years; I assume the other 5 years of experience include working as an intern while in graduate school and going through the licensing process. This doesn't really make a difference to me. I suppose I think of it in terms of my own field. I'm a professor and I would certainly count the 6 years I designed & taught college courses in grad school prior to earning my doctorate as "teaching experience." Anyone looking at my resume could see what year I earned my degree-- but if I was essentially doing the same job before and after (despite the salary difference!) I think it is fair to call it experience. Granted, if They are a newly minted T they should probably make that clear-- but at some point years of experience just become years.
