As an American who has a British PhD and 10 years of teaching experience I can tell you that not having academic transcripts has cost me a lot of good jobs. British PhD are earned through research only. However, to teach in the USA, especially at the graduate level, say, in psychology , the college will likely not hire you if they can't see what specific psychology courses you have taken at the graduate level. Also, many of the state accrediation agencies require transcripts to be in an employee's file upon inspection.
