To be accurate, a psychologist has a doctoral degree (Ph.D or Psy.D) and has a license through the Board of Psychology. A school psychologist has a masters degree and until recently had just the PPS credential to work in the schools. Now there is a new license through a different licensing board that that is different. There is a difference between a psychologist and a psychotherapist. Psychologists are very fussy about having that title after usually spending 5-6 years and $200,000 to get it.I would disagree with your understanding of what/who is a child psychologist. A family member is not only a school psychologist but also has his own practice. A nurse's aide is not a physician but a school psychologist is licensed the same as a private psychologist and in reality they have to have certain education classes and certificates added on top of their degree, volunteer hours and certification. Please do your research.
