Back to your question, as a psychological counselor, in theory, as long as you pass the qualification examination for psychological counselors, you are qualified to engage in psychological counseling. The professional qualification and judicial qualification of psychological counselors are also a legal prerequisite for practicing, but frankly speaking, psychological counselors now have a low threshold and low gold content compared with the judicial qualification examination. I feel that it is not difficult to pass after mastering the basic knowledge of psychology. But it is very difficult to become a real psychological counselor. The friend above said, "Only after reading a book with a price of 2K yuan can you become a psychologist." I think it's quite right, but this is only the minimum requirement. By the way, I think it is possible to become a professional psychological counselor by spending at least tens of thousands of yuan in training fees and several years of books at the same time.
As for learning that kind of psychology, the most basic general psychology, social psychology, developmental psychology, abnormal psychology and so on are all necessary. Of course, psychologists are divided into many branches, some focus on personal mental health development and education popularization, some focus on the treatment and correction of mental illness and psychological disorders, some focus on career development and human resources, and some may specialize in marriage, adolescence, parent-child relationship and so on. Then you will naturally choose a more professional direction after learning the basic theory.
