I agree, that to find information about the new Psych Mental Health NP, especially Texas programs is difficult. It seems there are few RN's out there interested in this role and specialty and most programs require full time enrollment at their university for Psych Master's Programs and enrollment is limited or only offered once every couple of years. Here is how I did it!
I researched for about one year. Got all the criteria. Kept current with ANCC, TX BNE, and a bunch of other sources of information about the role, ect, via internet and calls. I was able to utilize the information about CNS to NP role and sort of reverse it all.
First I became FNP at local university. Gained BNE approval with prescriptive authority. Then I did a Post-Master's in Psych Mental Health - only needed to take Individual, Family and Group therapy at that point. Currently, I am dually ANCC certified. In order to gain recognition in Texas was more difficult. The first step is to ensure that any program you enroll in is approved by the TX BNE, especially out of state programs. Your program must be approved by the Board, or you have to petition for a waiver. Which I had to do because Post Master's and Doctoral programs are NOT accredited by accrediting agency. But, any major university with a full Psych Mental Health NP and CNS program should have or has applied for LNL accreditation and will usually allow for a Post Master's.
A dilemma in an NP or CNS program may be the lack of certified and recognized APN's in psychiatry in your area in order to obtain clinical time and supervision. The Psych Mental Health NP and/or CNS must obtain 100 hours of supervision, of which I believe 35% must be by a nurse certified in same role and specialty. This will prove to be a major step as I am the only PMHNP I know of near Corpus Christi, and I think there may only be one or two CNS's in this region. I know of only one CNS that is in private practice regionally. But, her role is different than mine. However, the supervision is directed at psychotherapy, perhaps I will be able to obtain her, or else I will have to look to another area for my 35 hours. The rest will be provided by the group I work with.
Texas, in October, approved of the Adult Psych Mental Health NP. I took the Family PMHNP exam, so I will have to take yet another test. Once there are approximately 100 examinations completed, the TX BNE will look at the Family PHMNP exam for approval. I expect this to occur probably within a year as more nurses graduate from Family PMH NP programs. I suggest that you call the BNE before you take any exam to ensure the Board approves of the exam. I was told I can take any of the Psych CNS or Adult PMH NP exam and be recognized as NP, but to do this may result in non-recognition as NP by another state. I know this was an overkill almost, but at least I got it done.
I wish you the best, and remember that dreams are only reality waiting to happen!!!!
