Yikes, upon further investigation there are still states that allow this. You do not even need a high school degree to take this exam. and there is no curriculum. Here is some further info if anyone is interested. This is something I need to do more research on and I plan to read up on it a bit.

The part that stood out to me was:
of the nation’s 1,400 CPMs in practice today meet the educational and training standards accepted by ACOG and the ACNM. The educational background of CPMs—known in some states as direct entry or lay midwives—varies widely across the nation. Unlike CNMs, CPMs are not required to have a nursing background. They practice primarily in out-of-hospital settings, including birthing centers and private homes. Many CPMs have no formal academic education or medical training, and their training requirements fall short of internationally established standards for midwives and traditional birth attendants.
Other relevant points:
A person without a high school degree could be licensed as a CPM if he or she passed the certifying exam, observed 20 deliveries, and participated as the primary attendant in 10
As a group, CPMs have not adopted home-birth patient-selection criteria that are based on generally accepted medical evidence or public safety
The curriculum, clinical skills training, and experience of CPMs have not been approved by the American Midwifery Certification Board. Nor are they reviewed by the American Board of Obstetrics and Gynecology or the American Board of Family Medicine—recognized authorities in the certification of knowledge and skills associated with the practice of obstetrics.
The North American Registry of Midwives’ Portfolio Evaluation Process requires midwives to be the primary care provider during 50 home births and to have 3 years’ experience. The average ObGyn resident gets this much experience in 1 month."
