Evidence-based practice is the result of requiring empirical data for a positive outcome. Conversion therapy does not qualify for either, lacking both practice or training models and lacks empirical data to substantiate that practice. If there are no criteria for training one cannot qualify to be a professional deserving licensure in any field. Just because a parent wants to effect a change in their child does not mean that there is a reputable service provider for that change.  All major national health, psychological, educational and social service associations attest to the unsubstantiated benefit at best and deadly effects at worst of conversion therapy.  State regulatory boards must have evidence-based criteria, meet high standards of peer review and increase public confidence in a legitimate service by recognizing providers who meet clear professional standards. None of these criteria are met for conversion therapy. It must be outlawed for what it is: wishful thinking perpetuated by tradition and myth.
