Yes I am aware of those. None in places I truly want to live. Also, I've been told it's program dependent whether I do 3 or 4 years in psych residency. So may not matter. That said, because at the end of those, one could be board eligible in either adult or child/ adolescent psych, there is an appeal. Need to reach out to a program director to see what percentage of grads sit for both and what grads do. Thanks!
Not sure where you're getting your info but the way you're talking about this implies you aren't yet clear on the basics of psychiatry residency and fellowship training and possibly getting bad information.
Psychiatry is a four year categorical residency. Someone entering traditionally and not doing a fellowship will complete the program in four years. This includes six months of off service (two months of neurology and four months of some combination of medicine or EM, with peds being an acceptable option).
Child and adolescent fellowship is two years, but there is an option to 'fast track' in after year 3 and complete adult + child in 5 years. All other psych fellowships are one year, and none offer fast tracking, so someone in a typical path for psych who is fellowship trained did five years of training. There is NO way to be board certified in child and adolescent without also being board certified in adult psychiatry.
If you come to psych having done another residency first, you often can get credit for your off service months. And, sometimes you can sacrifice elective time. The details of any arrangement like this have to be worked out directly with your program. It could be feasible to finish in under four years and/or to start off cycle. Possibly you could get it all into three years. However, it would be unlikely to be able to fast track into child and adolescent doing this. So however much time you could shave off, if you wanted to do child, you would most likely still need to do the full two year fellowship.
The peds portal programs are custom built by the institutions to accelerate you through all the requirements for both general adult and child and adolescent in three years. So if you want to be a child psychiatrist, they are by far the most efficient way to do that. The cost of moving that quickly through all the requirements is the lack of flexibility.
