- RN experience: a minimum of 2 years (24 months) as an RN within the last 4 years.
- Breast-care practice: a minimum of 2,000 hours of breast care nursing practice within the last 4 years.
- Continuing education: at least 10 contact hours of breast care nursing CE (or an academic elective) within the last 3 years.
