Having a bunch of psychiatrists and psychologists as friends (met one, then made friends with their friends) this is a very universal thing among therapists.

To the point it's almost regulation via their ethics codes, that they take a test on made by the 'board' of psychology. It's definitely an industry norm. I found out 'the board' is mostly equivalent to Psychologist DMV and is run by the state, and is about as pleasant to interact with.
