What are the differences in your midwifery licenses?

In California and many other states, there are two types of midwives:  Certified Nurse-Midwives and Licensed Midwives.  A Certified Nurse-Midwife (CNM) is a registered nurse with additional training and certification in the practice of midwifery and who is licensed by the Board of Registered Nursing.  A California Licensed Midwife (LM) is held to the same standards and body of knowledge as a CNM but is licensed by the Medical Board of California and does not write prescriptions for allopathic medications.   Some Licensed Midwives are also registered nurses but most enter the midwifery profession directly as per the European and Canadian model of midwifery.
