IBCLC Examination Transition to Scaled Scoring Highlights
- Scaled scoring presents results in a standardised numerical format.
- The examination content and standards required for passing are not changing.
- Scores are shifting from raw scores to a scaled score range of 200 – 800, with 600 as the passing score.
- Scaled scoring makes results clearer, more interpretable, and more consistent across all examination versions.
- You’ll receive the same type of score report, on the same timeline, with no impact on examination difficulty or pass rates.
Transition to Scaled Scoring
Beginning with the April 2026 examination administration, the IBCLC Commission will transition from reporting raw scores to reporting scaled scores for the IBCLC examination. This change strengthens our commitment to clarity in the interpretation of results across all examination administrations.
Historically, IBCLC examinations have been scored using a proven equating process designed to promote fair evaluation of all candidates no matter which examination they took. The adoption of scaled scoring builds on that solid foundation by presenting results in a clearer, standardised numerical format used across many certification programmes.
What Is Scaled Scoring?
Scaled scoring is a method of transforming raw scores (the number of questions answered correctly) into a consistent and standardised numerical scale.
- Scores are comparable across different versions of the examination.
- The passing score remains fixed.
- Candidates can easily interpret their results.
Beginning with the April 2026 IBCLC examination, all results for the IBCLC examination will be reported on a 200 – 800 scale, with 600 as the passing score. This scale was determined in consultation with our psychometric partners and IBCLC subject matter experts.
Why the Change?
1. Enhanced Clarity for Candidates
Scaled scores offer a clear and consistent frame of reference. Instead of seeing a raw number of correct answers as was previously reported on candidate score reports, the reports will now show a score from the same standardised scale for each examination administration.
2. Alignment With Certification Best Practices
Scaled scoring is the preferred scoring methodology used in professional certification programmes. It offers a reliable way to better communicate performance while continuing to support rigorous psychometric standards.
