In what state do you want to become licensed?
Start by finding out the requirements to become a midwife where you want to practice midwifery. Does the state license direct-entry midwives, and if so do they have to be CPMs or CMs? What are the educational requirements? What will you be able to do when you get licensed: work in a clinic, deliver babies in a hospital, open your own homebirth practice, start a birth center? The MANA website
tracks the laws and regulations in each state for direct-entry midwives. Citizens for Midwifery maintains a State-by-State Guide
to midwifery in the US.
