I thought I would add some comments:
It was stated that "CNM stands for Certified Nurse Midwife. They're nationally licensed, ..."
To provide more clarity, CNM's are not
nationally licensed, but rather
the ACNM is the national certifying body that grants the CNM credential. The CNM credential is recognized in all 50 of the states and each state has it's own regulatory acts that provide avenue for licensure and regulatory control for the practice of licensed nurse-midwifery.
Likewise, NARM is the national certifying body that grants the CPM credential. The CPM credential is not yet recognized in all 50 states (I believe 25 states do). In many of the states, the CPM credential is necessary for licensure and those states have their own regulations in place for the practice of licensed midwifery.
CNMs have been certified since 1971; CPMs since 1994; CMs since 1997.
I like to think the CPM has been around long enough to not think of it as "a relatively new thing" ...being that it is 12 years old : )
The CPM, requires out-of-hospital experience as a necessary part of midwifery education. ACNM's certifications, the CNM & CM, does not require out-of-hospital birth experience.
"NARM is committed to identifying standards and practices that reflect the excellence and diversity of the independent midwifery community in order to set the standard for North American midwifery". (Utah Friends of Midwives)
