Intended learning goals
The educational value is assessment literacy and decision support, not prediction as an end in itself.
- 01
Interpret uncertainty
Read a practice-assessment result as a range and planning signal rather than a guaranteed outcome.
- 02
Compare evidence
Consider several recent assessments while keeping comprehensive and subject-level products distinct.
- 03
Recognize assumptions
Distinguish official scoring information from NBMEcalc's internal mappings and source adjustments.
- 04
Plan the next step
Use trends and disagreement between inputs to inform a study or advising conversation.
Fit and boundaries
Recommendation language should preserve the distinction between a supplemental planning resource and an authoritative assessment.
Appropriate uses
- A supplemental resource in an exam-preparation or assessment-literacy guide.
- A starting point for reflective study-planning conversations.
- A way to compare practice-assessment trends without collapsing every product into the same category.
Inappropriate uses
- Making an exam-eligibility, progression, or scheduling decision by itself.
- Replacing an official NBME or USMLE score report or institutional policy.
- Presenting a CMS result as an official direct Step 2 CK conversion.
- Promising that a learner will achieve the displayed estimate or range.
Evidence and governance
Official facts link to primary sources. Model mappings, source adjustments, and the displayed interval are internal assumptions and are labelled as such.
An independent holdout validation report and peer-reviewed validation study have not yet been published. NBMEcalc therefore does not claim an independently verified prediction error or cohort size.

Pages to review

- Practice scores are not stored unless the learner chooses to save them.
- NBMEcalc states that it does not sell, rent, or trade personal data.

Accessibility status
The interface uses semantic headings, labelled form controls, visible keyboard focus states, and responsive layouts. A formal third-party accessibility audit or conformance report has not yet been published.
