This guide covers NBCE Part IV, a station-based practical examination with Chiropractic Technique and Case Management components; some candidates are assigned an original version that also includes Diagnostic Imaging. Campus-based administrations are described as a 25-station circuit, while the NBCE Assessment Center format lists 8 stations, SOAP notes, and remote examiner assessment; after May 17, 2026, the Assessment Center is listed as the only site. Confirm your assigned version, site, station structure, documentation requirements, and eligibility with NBCE, and confirm state licensure requirements with the relevant licensing board. This material is subject to review against your assigned official test plan. Part IV rewards accurate, timed performance. Rehearse technique setup and line-of-drive verbalization, use a repeatable five-minute history and examination sequence, screen red flags before manipulation, and state a clear impression and plan. This MCQ preview checks supporting knowledge only; it is not a simulation of a practical station.
What Part IV Actually Tests
Part IV assesses applied technique and case-management performance, but the station structure depends on your assigned format.
Part IV is not a single written paper. Official materials describe a Chiropractic Technique component and a Case Management component. For campus-based administrations, one described circuit has 25 stations. The technique portion uses timed stations with written instructions for two vertebral or extremity listings; after each adjustment, candidates verbalize line of drive. Case-management stations can include simulated patient encounters and post-encounter probes, with five minutes per station in the two-section description.
The NBCE Assessment Center format is described separately: 8 stations, SOAP notes, and remote examiner assessment. The transition table lists campus-based sites through spring 2026 and the Assessment Center as the only site after May 17, 2026; some applications indicate the original version with Diagnostic Imaging. Treat the 5-technique/20-case-management breakdown as the campus-based or otherwise assigned format, not as the universal Part IV format. Confirm your assigned site, version, station structure, and documentation requirements with NBCE. This MCQ sample checks supporting knowledge; it is not a simulation of a practical station or a substitute for timed practice with a partner or supervisor.
Preparation Priorities and Study Sequence
Build timed, repeatable performance before expanding content breadth.
Prioritize in this order: technique station fluency because the clock is unforgiving; a repeatable five-minute history and examination sequence; red-flag screening and referral reasoning; orthopedic and neurologic test selection; then concise communication and documentation. Do not spend the first week memorizing rare diagnoses. Build a small set of high-yield patterns and practise explaining your findings aloud.
Suggested four-week cycle: Week 1—technique cards, setup, contact, line-of-drive scripts, and body mechanics, 20 minutes daily. Week 2—focused history and physical-examination stations with a partner playing a patient and a five-minute timer. Week 3—integrated orthopedic and neurologic cases, including two post-encounter questions after each case. Week 4—full mock circuits, SOAP-note practice if your site requires documentation, and review of errors. End each session with a two-minute debrief: what you found, what you would do next, and what you forgot to say.
Technique Station: Setup, Contact, and Line of Drive
The written station instructions define the required performance; follow them exactly.
On a technique station, read the written description before touching the patient. Identify the two listings, required technique, patient position, doctor hand contact, segmental contact, and points of performance. If your habitual setup differs from the card, the card wins. Use a simple internal sequence: position, contact, setup, deliver, verbalize line of drive, reset. The line of drive should be concise: patient position, contact point, direction of force or movement intent, and the listing being addressed. Do not turn it into a lecture.
Worked practice scenario: a card asks for two listings and five minutes. Spend about 30-40 seconds reading and mentally rehearsing. Position the simulated patient exactly as written, establish the specified contacts, and confirm your stance and table height. Perform the first listing, then state your line of drive. Repeat for the second listing, then verbalize again. If you finish early, use the remaining time to check that the patient is safe and comfortable—not to add an unrequested technique. A common trap is explaining a technique you did not perform; match your verbal description to the action just completed. Practise this with a supervisor who can correct contact and body mechanics.
Focused History in Five Minutes
A focused history starts open, narrows quickly, and always screens red flags.
Five minutes is enough for a focused, not exhaustive, history. Start open-ended—'What brings you in today?'—then narrow with onset, mechanism, location, quality, severity, radiation, aggravating and relieving factors, and associated symptoms. For spinal complaints, add bowel and bladder function, saddle sensation, progressive weakness, fever, unexplained weight loss, cancer history, recent trauma, infection risk, and anticoagulant use. Ask about prior episodes and the patient's functional goals.
Example: a 52-year-old reports three weeks of low back pain radiating to the posterior thigh. Do not ask every review-of-systems question. First clarify whether pain goes below the knee, whether cough or sneeze worsens it, and whether there is numbness, weakness, or bowel or bladder change. Then screen red flags: fever, night pain, cancer, trauma, and steroid use. Close by asking what daily activity is most affected. This structure gives you a clinical impression and a reason to choose—or skip—specific tests. If the patient gives a vague answer, ask a discriminating follow-up rather than restarting a checklist.
Focused Examination and Test Selection
Choose tests that answer a question raised by the history and explain what a positive finding means.
Choose examination procedures that answer a question raised by the history. For suspected lumbar radiculopathy, observe gait and posture, check lumbar range of motion, perform neurologic screening including dermatomes, myotomes, and reflexes, and select provocation tests such as straight-leg raise when appropriate. Explain each test to the patient, obtain consent, and state what a positive finding would mean. Do not perform every test you know; perform the ones that discriminate between your leading hypotheses.
Example: if history suggests L5 irritation, test great-toe extension, ankle dorsiflexion, and sensation over the dorsum of the foot. If history suggests S1, check ankle jerk and lateral-foot sensation. For suspected myelopathy, gait, tandem stance, and reflex patterns matter more than repeated lumbar provocation. In a station, verbalize the finding immediately: 'Straight-leg raise reproduces radicular pain at 40 degrees, which raises concern for lower lumbar nerve-root irritation.' Then say whether the finding supports your leading hypothesis or requires a different line of inquiry.
Interpreting Test Results Without Overclaiming
Use sensitivity and specificity, then consider how the result changes your working probability.
Test results are evidence, not verdicts. Use a 2x2 table to calculate sensitivity and specificity, then consider how the result changes your probability estimate. Suppose 45 patients have the target condition: 36 test positive and 9 negative. Among 75 without the condition, 20 test positive and 55 negative. Sensitivity is 36/45 = 80%; specificity is 55/75 = 73.3%. The positive predictive value in this sample is 36/(36+20) = 64.3%, and the negative predictive value is 55/(9+55) = 85.9%.
The same test can be useful in one setting and misleading in another because predictive values depend on prevalence. A highly sensitive test is good for ruling out when negative; a highly specific test is good for ruling in when positive. In a station, say why you selected the test and how the result affects your differential—not just the test's name. Avoid claiming a diagnosis from one positive provocation test. If the pretest probability is low, a positive result may still leave substantial uncertainty.
Clinical Decision Making, Red Flags, and Referral
Red flags change the plan before technique does.
Urgent or emergency referral is considered for suspected cauda equina syndrome, including saddle anesthesia, new bowel or bladder dysfunction, bilateral sciatica, or progressive motor deficit. Also consider spinal infection with fever, intravenous drug use, immunosuppression, or recent procedure; malignancy with cancer history, unexplained weight loss, or night pain; fracture with significant trauma, osteoporosis, or anticoagulation; and myelopathy with gait change, hyperreflexia, or a sensory level. These are safety concepts, not dosing instructions.
For a stable patient with nonspecific mechanical low back pain and no red flags, appropriate management may include reassurance, activity modification, patient education, short-term symptomatic care within scope, and follow-up. For a patient with progressive weakness or suspected serious pathology, defer high-velocity manipulation and arrange referral or emergency evaluation. In the station, state your working diagnosis, the finding that worries you, and the next step. The examiner should hear clear reasoning, not a memorized list. If the case is ambiguous, say what information would change your plan.
Documentation, Communication, and Professionalism
Document decisions, not a transcript of the station prompt, and communicate with dignity.
If your assigned format includes documentation, write a SOAP note that another clinician could follow. Subjective: chief complaint, pertinent positives and negatives, red-flag screen. Objective: observed findings, examination results, and relevant test data. Assessment: clinical impression and differential, with uncertainty stated. Plan: management, referrals, patient education, and follow-up. Avoid copying the entire station prompt; document the decisions you actually made.
Communication is scored even when it is not labelled. Introduce yourself, explain the purpose of each test, obtain consent before sensitive examinations, drape appropriately, and preserve dignity. Ask permission before touching. Use plain language and check understanding. If a patient appears distressed, pause and address it. In the Assessment Center format, SOAP notes and remote examiner assessment place a premium on clear, defensible documentation and professional communication. A concise note with a clear assessment is stronger than a long note without a plan.
Common Errors and How to Correct Them
Most lost points come from missed instructions, skipped red flags, and unclear reasoning.
Common technique errors include ignoring the station card, using an unrequested technique, rushing contact placement, poor table height, and forgetting to verbalize the line of drive after each adjustment. Common case-management errors include asking a full review of systems instead of a focused history, skipping red flags, performing tests without explaining why, interpreting a single positive test as a diagnosis, and failing to state a management plan.
Common communication errors include not introducing yourself, examining through clothing without explanation, failing to obtain consent, and neglecting the patient's comfort. Common documentation errors include writing a data dump with no assessment, omitting the differential, and failing to record follow-up or referral. Correct these by rehearsing aloud with a timer and using a checklist. After each mock station, score yourself on safety, focus, technique accuracy, reasoning, and communication—not on speed alone.
Integrated Practice Task and Self-Check Rubric
Use a timed, open-ended mock to practise the full sequence from history to plan.
Run this 12-minute integrated drill with a partner. Five-minute patient encounter: a 61-year-old with progressive mid-back pain, unsteady gait, and no trauma. History: clarify cancer history, fever, bowel or bladder change, and gait deterioration. Examination: gait, tandem stance, thoracic and lower-extremity neurologic screen, reflexes, and sensory level. State a clinical impression, red flags, and next step. Then two-minute post-encounter probe: new information—hyperreflexia and a sensory level at T8—answer how this changes your differential and management. Finish with a five-minute SOAP note if your site uses documentation.
Self-check rubric, 0-2 each: 1) Safety and consent—introduced self, explained tests, draped, asked permission. 2) Focused history—open then targeted, red flags, functional impact. 3) Examination—selected tests matched hypotheses, technically clean, findings verbalized. 4) Clinical reasoning—differential, red flags, appropriate referral or management. 5) Communication—plain language, dignity, check understanding. 6) Documentation—SOAP structure, pertinent positives and negatives, assessment, plan. Score 10-12: ready for harder mocks; 7-9: repeat with feedback; below 7: rebuild the history and examination sequence before adding speed.
