1.3 Scoring, Fees, and Retakes

Scaled Scores: Why 375 Is Not a Percentage

NBCE Part II reports a scaled score, not a raw count of 255 correct answers. The required passing score is 375 on a scale that runs from 125 to 800. This confuses many first-time candidates who expect something like "75%" because classroom exams use straight percentages.

What scaling accomplishes

NBCE uses Classical Test Theory and Item Response Theory, then equates forms so that scores are comparable across administrations. Scaling therefore:

• Adjusts for slight differences in difficulty between exam forms administered on different dates.
• Weights harder items more heavily, so two candidates with the same number correct can receive different scaled scores.
• Allows NBCE to maintain a consistent pass standard even when item pools rotate.

NBCE states plainly that there is no direct relationship between the percentage of correctly answered items and the scaled score. You cannot reliably convert a practice-test percentage into a predicted scaled score—the equating tables are not public. A student who scores 78% on a third-party bank and a student who scores 72% might both pass on live exam day depending on item difficulty and domain balance.

What you see on score release

Scores post to MyNBCE roughly four weeks after the examination, on the published score-release date for your testing window (release is a rolling process that can take 48+ hours to finish). Your release includes:

• Overall scaled score and pass/fail relative to the 375 standard.
• Domain performance feedback showing relative strength and weakness.

Domain lines are diagnostic information only. Since the 2024 scoring change, individual domains are not separately scored or separately passed—the domain report exists to tell you where to study, not to tell you which piece to repeat.

Pass/Fail Logic: Compensatory Scoring Across Six Domains

Part II is scored collectively across all six domains for a single overall pass decision. This model is compensatory: a surplus in one domain can absorb a minimal deficiency in another. NBCE's own analysis of administrations since 2019 found that a surplus elsewhere was usually enough to cover a minimal deficit in one—or even two—weak domains.

The compensation has limits. A significant deficit in a domain cannot be rescued by strength elsewhere, and roughly 10% of examinees who failed two domains under the old model had deficits deep enough to fail outright under the new one.

Trap: ignoring "low pass" domain patterns. You cleared 375 today, but the same weakness in Part III imaging-heavy content can become a hard stop later.

Fee Structure and the End of Individual Domain Retakes

NBCE publishes fees on the official fee schedule. For Part II there is now one number to budget:

Individual domain retakes ended January 1, 2026

This is the single most important policy change for anyone reading older prep material. When NBCE moved Parts I and II to the 255-item, six-domain compensatory model in August 2024, it allowed candidates who were already eligible for individual domain retakes (IDR) to finish them through the end of 2025. Effective January 1, 2026, the NBCE no longer allows candidates to retake individual domains within Parts I or II. A candidate who wishes to retake Part II must retake the full Part.

Practical consequences:

• There is no $335 per-domain option to plan around. Older guides, forums, and course notes that quote it are describing a retired policy.
• The cost of failing is the full $710, every time.
• Because you cannot repair one domain in isolation, a narrow blind spot is now as expensive as a broad one—which is exactly why blueprint-complete preparation beats domain triage.

Hidden costs candidates forget

• Travel and lodging for Prometric or distant college sites.
• Reschedule fees—pure loss if you miss windows.
• Remedial courses your chiropractic college mandates after failure.
• Delayed graduation or licensure timeline—opportunity cost often exceeds $710.

Build a total cost envelope of $1,000-$1,500 for a first attempt with one reschedule margin.

Rescheduling and Withdrawal Windows

Prometric scheduling for NBCE exams follows tiered deadlines tied to days before the appointment:

Treat day 17 as your real deadline. NBCE's 2026 CBT schedule closes scheduling 17 days before each test date at 4:00 p.m. Mountain Time, and the current Examinee Agreement states that fees are not refunded for a change or cancellation made within 17 days. Where NBCE's pages differ by a day or two, the conservative reading is the one that protects your $710.

Scenario planning

Scenario A: You sprain your wrist 28 days out and cannot type comfortably.

• You are in the $50 fee window. Pay the fee or risk a wasted $710 seat.

Scenario B: A family emergency hits 10 days out.

• You cannot reschedule online. Missing the appointment typically means forfeiting the exam fee unless NBCE grants an exceptional circumstance under their policies (document everything; do not assume automatic grace).

Scenario C: You feel underprepared 35 days out.

• Free reschedule is available—use it. Ego-driven testing is the fastest way to fund NBCE twice.

Put NBCE and Prometric deadline dates in your calendar the day you schedule, not the week before.

Retake Pathway: One Road Back

Since January 1, 2026 there is a single retake path: re-register and sit the complete 255-item Part II exam again at $710. Build the retake plan from your domain feedback report:

1. Read the domain report before paying anything. It is now purely a study map—it no longer defines what you sit for.
2. Rank domains by weighted exposure, not by how bad they felt. General Diagnosis (19%) and Neuromusculoskeletal Diagnosis (20%) move the scaled score most; Associated Clinical Sciences (13%) moves it least per hour invested.
3. Rebuild the weakest domain to a verified metric (for example, imaging drill accuracy above 85%) rather than to a feeling of familiarity.
4. Re-rehearse the whole exam. Because the retake is full-length, endurance and pacing decay are real risks even in domains you previously passed.
5. Confirm registrar eligibility early—retesters and graduates follow additional NBCE eligibility documentation requirements.

Remediation and college policies

Many chiropractic colleges require:

• Advising meetings after failure.
• Completion of remedial modules before the registrar will re-certify eligibility.
• Proof of additional clinic hours or tutoring for NMS weakness.

NBCE fees and college remediation are independent gates—paying $710 does not bypass registrar holds.

Score Validity and State Boards

NBCE does not expire Part II scores on its own timeline, but state chiropractic boards may refuse scores older than a defined number of years for licensure applications. If you pass Part II but delay Parts III/IV or graduation:

• Confirm score age limits in your practice state.
• Archive PDF score reports from MyNBCE immediately upon release.

Note also that you may not retake an NBCE exam you have already passed in order to raise the score, unless a state licensing authority requires it in writing.

Financial and Strategic Decision Tree

Apply ($710) -> Schedule
    |
    +- >=30 days out need change? -> Free reschedule
    +- 29-16 days need change? -> $50 fee
    +- <=17 days issue? -> Sit or forfeit fee

Score release (about 4 weeks)
    |
    +- Scaled >=375 -> Plan Part III/IV sequence
    +- Scaled <375  -> Read domain report as a study map
            |
            +- Full-Part retake ($710) - no domain-only option since 1/1/2026

Ethical and Administrative Reminders

• Pay only through official MyNBCE workflows—third-party "guaranteed pass" services are scams.
• Keep payment confirmations and appointment emails until licensure completes.
• If you dispute a score, follow NBCE's official inquiry channels; anecdotal social media advice is not policy.

Understanding scoring and fees is not ancillary—it defines how many shots you can afford. With individual domain retakes retired, the 375 standard and the $710 fee are now a single, blunt pairing: every attempt is all six domains, and every failure costs the full amount.
