What conditions do psychological counselors need to have before they can apply?

Conditions for applying for the psychologist's certificate: at least 20 years old, college degree or above (including college) can apply.

You can choose exams organized by third-party organizations. If you apply for the exam, you are basically college or above, and your major is not limited. Of course, if you have a degree, it is not uniform. If the certification bodies are different, some institutions will relax the conditions appropriately, depending on the certification body you choose.
