The CPM credential requires that all candidates demonstrate a mastery of critical clinical components of midwifery care. The experience that leads to this proficiency can take many forms. For Entry-Level candidates seeking certification through the Portfolio Evaluation Process (PEP), NARM relies on experienced preceptors who validate the knowledge and skills acquired by their apprentices. Similar to a medical intern or resident, a midwifery apprentice is exposed to a variety of experiences that affirm didactic knowledge. NARM encourages aspiring midwives to establish solid and lasting apprenticeships with qualified preceptors who can provide the best examples for professional practice.
