DNP CLINICALS

Hello everyone. I am researching post-masters DNP programs and noticed that Frontier offers an option where your place of employment can be counted toward your clinical hours. I am just wondering if all of the DNP programs allow this or is this just an option for certain schools? I would think that if you are already working as an advanced practice nurse that doing additional clinical hours outside of that would be unnecessary. Anyone else currently in a DNP program that allows this?
