‥ Health care professionals and students must complete eligibility requirements set by the International Board of Lactation Consultant Examiners to become lactation consultants (IBLCE). After lactation consultant training, the IBLCE will administer a competency assessment. Certified lactation consultants (CLCs) receive accreditation after passing.

‥ Within the first five years after receiving their original certification, lactation consultants are required to earn at least seventy-five continuing education recognition points (also known as CERPs) in order to keep their certification current.

‥ The IBLCE must authorize all breastfeeding-related continuing education events. CERPs are not the only means to maintain certification. Lactation consultants can retake and recertify. The Northern Illinois Lactation Consultants Association (NILCA) can help Illinois lactation consultants achieve CERPs.

Many lactation consultant trainees in Michigan aim for Michigan certification. Lactation consultants in Michigan can practice without national certification, but certification gives up more job prospects. The International Board of Lactation Consultant Examiners (IBLCE) credential is preferred by many businesses (IBLCE). Michigan lactation consultant jobs are more likely to go to certified candidates.

IBLCE is administered annually. To take the exam, candidates must have at least 45 hours and preferably 80 to 150 hours of health, human lactation, and nursing education and 1000 hours of clinical experience (paid or volunteer). Since most lactation consultant certification courses are at nursing programs, some students choose to get a nursing degree.

Since 1985, the minimum required score to pass the examination has been determined by the IBLCE by using statistical analysis of each component of the test. This analysis causes the minimum required score to shift from year to year. The minimum required score to pass the test in April 2016 was 128, which corresponds to around 73 percent of the total. It would appear that around 85 percent of candidates for the IBLCE test are successful in passing it each year.

The minimum required score for passing is established by the IBLCE on an annual basis. In recent times, the minimum score required to pass has been around 75%, give or take a tiny bit. Because of this, around 70–80% of people who take the exam will pass.

IBCLCs have a higher possibility to come from a clinical or academic background (for example, doctors and registered nurses), whereas CLCs have a greater tendency to have a more holistic mindset (registered midwives, doulas, etc). When it comes down to it, the manner in which someone conducts themselves could be more essential to you than their education or their expertise.

Lactation consultants may provide a sense of calm throughout a potentially stressful period by responding to queries, offering guidance, and assisting with the problem-solving aspects of nursing. When it comes to feeding problems, it might be beneficial to have the opinion of a lactation consultant, even if you are an experienced professional.

An IBCLC will not be able to identify a tongue tie, but they will be able to evaluate the situation and recommend the patient to another healthcare expert for the diagnosis. LLL Leaders as parent-to-parent support volunteers are unable to identify tongue knots.

It might take anything from one to five years to complete the training necessary to become a lactation consultant. Within the five years immediately prior to submitting an application to take the International Board Certified Lactation Consultant (IBCLC) exam, applicants are required to complete a minimum of 90 hours of lactation-specific coursework.

With the baby’s head tilted back and chin up, lift him or her so that his or her nipple touches yours. The nipple should lie slightly above the top lip of the infant.

‥ To apply for the test, you must complete the qualifying requirements, which include 95 hours of lactation-specific instruction.

‥ Determine how (or if) you are recalling and implementing the material you have learnt.

‥ Acquire a thorough understanding of specialized vocabulary.

‥ Read items that will assist you in recalling or reinforcing necessary information. ‥ Taking practice examinations is one of the most significant things you can do to prepare for the IBCLC exam.

IBCLC content outline and where to practise each area

The content areas below are copied from the official IBCLC content outline published by International Board of Lactation Consultant Examiners (IBLCE) / IBCLC Commission. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through IBCLC questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: A new mother is having difficulty with the milk ejection reflex. She reports feeling stressed and anxious during feeding times. The inhibition of which hormone is the most likely physiological reason for her difficulty?

1. Prolactin
2. Thyroxine
3. Insulin
4. Oxytocin

Answer: D. Oxytocin

Explanation:

Correct answer: D, Oxytocin. Oxytocin is released from the posterior pituitary. It makes the myoepithelial cells around the alveoli contract, which pushes milk into the ducts. That is the let-down. Stress, pain, anxiety and embarrassment raise adrenaline, which can block oxytocin release, so milk that is already in the breast does not flow well.

• Prolactin drives milk production, not milk ejection.
• Thyroxine affects metabolic rate and, when abnormal, overall supply, but it does not trigger let-down.
• Insulin regulates glucose and plays a part in lactogenesis, but it has no role in the ejection reflex.

Rule to remember: prolactin makes milk; oxytocin moves it. If a let-down problem is linked to emotion or pain, think of oxytocin inhibition and focus on comfort and calm feeding routines.

Example 2

Question: What is the recertification cycle for the IBCLC credential?

1. 3 years
2. 5 years
3. 10 years
4. 15 years

Answer: C. 10 years

Explanation:

Correct answer: B, 5 years. Our earlier answer key marked C, 10 years. That reflected the old rule that IBCLCs had to retake the exam every 10 years. IBLCE dropped that rule. Certification now runs on a 5-year cycle, and at each renewal an IBCLC recertifies either by CERPs with the CE Self-Assessment or by sitting the exam again.

• A, 3 years, is not the IBCLC cycle.
• C, 10 years, is outdated. It was the old interval for recertifying by exam.
• D, 15 years, is not the IBCLC cycle.

Rule to remember: the IBCLC credential is renewed every 5 years, and retaking the exam is now an option rather than a requirement. Be wary of study materials that still say otherwise.

Example 3

Question: Which immunoglobulin is most abundant in human breast milk and provides mucosal immunity to the infant?

1. IgG
2. IgM
3. IgE
4. Secretory IgA (sIgA)

Answer: D. Secretory IgA (sIgA)

Explanation:

Correct answer: D, Secretory IgA (sIgA). sIgA is the main immunoglobulin in human milk. Its secretory component protects it from digestion, so it survives in the infant's gut. There it coats the mucosal linings of the digestive and respiratory tracts and stops pathogens from attaching. This is passive mucosal immunity.

• IgG is the main antibody that crosses the placenta before birth. It is present in milk only in small amounts.
• IgM is present in milk, but in smaller quantities, and it is not the main type.
• IgE is linked to allergic responses and is not a significant protective antibody in milk.

Rule to remember: the placenta gives IgG; the breast gives secretory IgA. Questions about protection of the infant's mucosal linings by milk point to sIgA.

How to use these practice tests

Start with the IBCLC Certification Exam set to get a mixed baseline. Note which content areas cost you the most points. Then work through the matching topic sets in the table above. Read every explanation, including on questions you got right, because a lucky guess teaches you nothing.

Download the IBLCE Candidate Information Guide and the official content outline and use them as your checklist. For each area, list the terms, hormones, conditions and medications you could not explain without looking them up. Review those in your lactation education materials, then retest with the same set.

The real exam has 175 questions in 4 hours, so build stamina. Combine several of our sets into long sittings and keep a steady rhythm instead of lingering on hard items. If you plan to use Live Remote Proctoring, check your room, computer and connection against Prometric's requirements well before your appointment.

In the final days, go back to the Common Clinical Challenges and Ethics and Professional Conduct sets. They mix judgement with knowledge. Stop adding new material at that point.
