The Certified Lactation Counselor (CLC®) credential is a professional certification for individuals who support breastfeeding and lactation. The program is administered by the Academy of Lactation Policy and Practice (ALPP) and has been accredited by the ANSI National Accreditation Board (ANAB) since 2013, with accreditation valid through 2028. This accreditation means the certification meets the ISO/IEC 17024 standard for personnel certification bodies, covering fairness, reliability, validity, impartiality, and governance. The CLC® exam assesses the knowledge and skills required for lactation counseling. While the source does not enumerate specific content domains, candidates should expect questions on breastfeeding management, counseling techniques, and related maternal and infant health topics. To prepare, review the scope of practice and exam blueprint on ALPP’s website, study reputable lactation texts, and consider training courses. Topics on this exam: CLC® certification examination content (domains not enumerated in source). The CLC study guide has 1 section and about 2,819 words.
01Maternal and Infant Anatomy and Physiology of Lactation
This domain tests whether you can explain, in plain language for a parent, how the breast makes milk and how the infant removes it. Items rarely ask for pure anatomy recall; they connect a structure or hormone to a clinical picture - delayed secretory activation after a cesarean, impaired milk ejection after a difficult birth, or a supply drop following several weeks of long night intervals. Glandular tissue is organized into roughly 15–20 lobes per breast, each drained by a lactiferous duct that widens into a sinus beneath the areola and then narrows to its own nipple pore (commonly 4–18 per nipple). Alveoli are lined with milk-secreting lactocytes, surrounded by myoepithelial cells that contract under oxytocin to move milk forward.
