LLG and Elkpark. Thanks very much for your thoughtful answers.
When I look at my educational path. It's more like the NP than CNS.
I did both my CNS's as post MSN certificates. My MSN was management and leadership.
For the post-MSN certificates I took adv path, adv pharmacy and adv assessment. The adult CNS had 576 hrs clinical and the pees CNS had 512 hrs.
I never took a CNS specific roles class though an APN roles class was part of the MSN. I also had project management, finances for healthcare admin, etc.
