An IBCLC is an International Board Certified Lactation Consultant.
To qualify to be certificated as an IBCLC, you have to obtain health-science credentials, through specific classes, lactation specific education credentials, obtained through 90 hours of class work, as well as extensive lactation specific clinical experience, by providing many hours of assistance to pregnant and breastfeeding women.
Then, the exam is given worldwide on the same day, making it the only internationally standardized lactation credential available.
An IBCLC must re-certify every 5 years by testing or continuing education hours, and every 10 years by re-testing.
