In our country, professional and technical certification, such as psychological counselor, pedagogy, psychology and medicine, can be applied for. But teachers can only take the exam in pedagogy, that is, normal candidates.
Therefore, mental health education is attached to psychology in nature, which is equivalent to psychology in vocational certificates.
Of course, this is the current rule, and no one knows what the policy is after graduating from the self-study exam. I am a self-taught student in psychology. I suggest that if you want to be a psychologist, don't study this subject which focuses on education.
