Start testHow these IBCLC practice tests match the real exam
The real IBCLC Certification Exam (Lactation Consultant) has 175 questions and a 240-minute time limit. Question types: Multiple choice: each question has a stem and four response choices with one best answer, and there is no penalty for wrong answers. Questions are text-only, linked to an image or graphic, or based on a case study or written record of a lactation consultation. Most questions in Part Two are associated with an image. Each practice test here uses the same question formats, so you get used to how IBCLC questions are asked before test day.
The tests draw on every IBCLC content area, weighted like the official outline:
- Development and Nutrition (about 18.3% of the exam)
- Physiology and Endocrinology (about 8% of the exam)
- Pathology (about 20% of the exam)
- Pharmacology and Toxicology (about 8% of the exam)
- Psychology, Sociology, and Anthropology (about 11.4% of the exam)
- Techniques (about 14.3% of the exam)
- Clinical Skills (about 20% of the exam)
Use tutor mode to see the explanation after each answer, or timed mode to practise at real exam pace. Every answer comes with an explanation of why it is right and why the other options are wrong.
