The NMC OSCE Glasgow Coma Scale (GCS) station is a critical component of the Objective Structured Clinical Examination (OSCE) for nurses seeking UK registration. In the 2026 exam format, candidates are assessed on their ability to systematically evaluate a patient’s level of consciousness using the GCS tool. This is often within a complex scenario, such as a subdural haematoma or head injury.
Key updates for 2026 include the strict adoption of the term “To Pressure” instead of “To Pain.” It is now required to verbalise monitoring frequency in line with NICE head injury guidance and local trust policy. For example, 30-minute neurological observations until GCS reaches 15 should be performed, with reduced frequency once stable, and immediate escalation for any deterioration. Precise documentation on the specific GCS observation chart is also essential.
Success relies on demonstrating clinical reasoning by explaining why a score is assigned. Candidates must integrate the GCS into a holistic A-E assessment while avoiding safety red flags like unsafe stimulation methods.

The Criticality of Neurological Assessment in 2026: Why This Station Matters
The journey to becoming a Registered Nurse in the United Kingdom is one of rigorous preparation and clinical excellence. At the heart of this process lies the Test of Competence Part 2, the Objective Structured Clinical Examination (OSCE). Among the various stations that test a candidate’s mettle, the neurological assessment-anchored by the Glasgow Coma Scale (GCS)-stands out as a frequent source of apprehension. This is not merely because of the technical complexity of the scale, but because it represents a high-stakes clinical moment: the deterioration of a patient’s brain function.
In the rapidly evolving landscape of UK healthcare, the Nursing and Midwifery Council (NMC) has updated its standards for 2026 to emphasize not just procedural competence, but clinical reasoning and person-centred care. It is no longer sufficient to mechanically assign a number to a patient’s response. The modern OSCE candidate must demonstrate an understanding of the physiological underpinnings of consciousness, the safety implications of their assessment techniques, and the ability to communicate empathetically with a confused or distressed patient
Why Examiners Test GCS:
In 2026, the NMC Assessment Station focuses heavily on three critical domains:
1. Systematic Assessment – Your ability to adhere to the A-E (Airway, Breathing, Circulation, Disability, Exposure) framework even when faced with a distracting neurological presentation
2. Diagnostic Accuracy – The ability to accurately differentiate between subtle signs (Confused vs. Inappropriate Words; Localises vs. Withdrawal), which fundamentally alter the GCS score and subsequent clinical management
3. Escalation Protocol – The ability to act on the data. A nurse who correctly calculates a GCS of 12 but fails to escalate has failed patient safety
The GCS station is designed to simulate the pressure of a real-world ward environment where a patient’s life may hang in the balance. A drop in GCS score is often the earliest warning sign of catastrophic intracranial events, such as expanding haematomas or cerebral edema. Consequently, the marking criteria for this station are unforgiving of safety breaches. A failure to recognize a deteriorating score, or the use of unsafe stimulation techniques, can lead to an immediate failure of the station.
This comprehensive guide, aligned with the latest 2025/2026 marking criteria and examiner feedback, serves as the definitive pillar resource for mastering the NMC OSCE GCS station. Whether you are beginning your OSCE journey or preparing for a resit, this guide offers the depth and insight required to pass with confidence.
Understanding GCS: Historical Context and 2026 Updates
The Glasgow Coma Scale, developed in 1974 by neurosurgeons Graham Teasdale and Bryan Jennett, is the gold standard clinical tool for assessing consciousness and brain injury severity internationally. In the NMC OSCE, it forms the foundation of your neurological assessment, particularly in scenarios involving head injury (subdural haematoma), stroke, or acute confusion.
The Evolution of Clinical Terminology: “Pain” to “Pressure” (2026)
For decades, nurses were trained to assess a patient’s response to “Pain.” The 2026 NMC OSCE standards, reflecting broader changes in UK clinical practice and the NMC Code, have shifted this terminology to “Pressure”. This change is profound and reflects a commitment to non-maleficence-the ethical duty to do no harm.
Why This Matters:
In the exam, stating “I am going to check the patient’s response to pain” is now considered outdated and potentially marks a candidate down for failing to use current professional terminology. The correct phrasing is, “I will assess the patient’s response to a physical pressure stimulus. In OSCE, sternal rub and supraorbital pressure should be avoided due to risk of injury and patient distress.” This linguistic shift must be accompanied by the correct physical technique: the Trapezius Squeeze (not sternal rub or supraorbital pressure, which are now flagged as aggressive or carrying risk of injury).
Correct OSCE Verbalisation:
“I am going to apply gentle pressure to your shoulder to check your response.” (Then perform Trapezius Squeeze, not pain stimulus.)
Common Mistake:
· ❌ “I’m going to apply pain to check your response”
· ✅ “I’m going to apply gentle pressure to check your response”
This single terminology shift reflects the modern professionalism expected of UK-registered nurses.
Marking Breakdown: Where the Points Really Are
Simply calculating a score gets you about 40% of the marks. Demonstrating what you’d do with that score-clinical reasoning and escalation-gets you the remaining 60%.
· 40%: Technical accuracy (correct E-V-M scoring)
· 35%: Clinical reasoning & escalation (interpretation of score, appropriate monitoring frequency, escalation to medical team)
· 15%: Communication & person-centred care (explaining findings to patient, reassurance)
· 10%: Documentation & professionalism (chart clarity, legal precision, time management)
The Three Components of GCS: Complete Breakdown
The Glasgow Coma Scale assesses three separate neurological domains. Each is scored independently, then added together for a total score.
1. Eye Opening (E) – Scored 1 to 4
What You’re Assessing: How readily the patient opens their eyes in response to different stimuli.
Scoring Rubric:
| Score | Response | What This Means in Practice |
| E4: Spontaneous | Eyes open without any stimulus | Patient is alert; normal consciousness level. Eyes already open when you approach. |
| E3: To Sound | Eyes open only to verbal stimulus (your voice) | Patient is drowsy but responds to your voice. Say clearly: “Open your eyes, please.” Count to 2, then score. |
| E2: To Pressure | Eyes open only to painful stimulus | Patient doesn’t respond to voice. Apply a central pressure stimulus, preferably a trapezius squeeze, which is the recommended and safest method in OSCE settings. |
| E1: None | No eye opening despite stimuli | Most severe; indicates deep coma or unconsciousness. |
| NT | Non-testable | Use if local factors prevent assessment (e.g., periorbital edema, closed eyelids from swelling). Don’t force if eyes are swollen shut. |
Table 1: Eye Opening (E) Scoring Criteria
Common Mistake (From Examiners):
Many nurses skip the verbal stimulus and jump straight to pain. Always progress systematically: spontaneous → sound → pressure. This shows the examiner you understand the neurological hierarchy. Only use pain if the patient hasn’t responded to voice.
Key Verbalisation:
“I’m going to check how you respond to different stimuli. First, I notice your eyes are already open-that’s a spontaneous response, so E4. If you weren’t already awake, I’d call out to you, then apply gentle pressure if needed.”
2. Verbal Response (V) – Scored 1 to 5
What You’re Assessing: The quality and orientation of the patient’s speech.
Scoring Rubric:
| Score | Response | What This Means in Practice |
| V5: Oriented | Fully oriented to time, place, and person | Patient answers correctly: “What’s your name?” “Where are we?” “What’s today’s date?” If they answer all three correctly, V5. |
| V4: Confused | Speaks coherently but is disoriented | Patient converses but answers aren’t quite right. Thinks it’s 2023 when it’s 2026. Can follow conversation but not oriented. |
| V3: Inappropriate Words | Speaks words, but they’re random or unrelated | Patient utters real words but they don’t connect. E.g., when asked “Where are you?” responds “Purple elephants.” |
| V2: Sounds Only | Makes incomprehensible sounds (moaning, groaning) | No intelligible words; only sounds like grunts, moans, or groans. Often accompanied by facial grimacing. |
| V1: None | No verbal response at all | Complete absence of sound, even to painful stimuli. |
| NT | Non-testable | Use if patient is intubated (has a breathing tube) or unable to speak. Write “NT” and do not include in total score. |
Table 2: Verbal Response (V) Scoring Criteria
Critical Rule (From 2026 NMC Standards):
If a patient is intubated or unable to speak, do NOT guess a verbal score. Document “V: NT (intubated)” and calculate a total score excluding V. Always document the individual E, V, and M scores clearly with date, time, and signature, rather than relying only on a total score. Example: E3 V-NT M5 = not a total of 13, but rather document E3 and M5 separately with notation that verbal response is non-testable.
Common Mistake:
Nurses often conflate “confused” with “inappropriate words.” Confused (V4) means the patient is still making sense but disoriented. Inappropriate words (V3) means the patient is saying things that don’t match reality.
Key Verbalisation:
“I’m assessing your orientation. Can you tell me your full name? Do you know where you are right now? What’s today’s date? [Listen to answers]. You’re oriented to person but confused about place-that’s V4 Confused.”
3. Motor Response (M) – Scored 1 to 6
What You’re Assessing: The patient’s best motor response to commands and stimuli.
Scoring Rubric:
| Score | Response | What This Means in Practice |
| M6: Obeys Commands | Patient follows simple verbal commands | “Squeeze my hand.” “Lift your leg.” If they do it correctly, M6. Most common in alert patients. |
| M5: Localises Pain | Patient moves hand to source of painful stimulus | When you apply pain (trapezius squeeze), patient reaches toward the pain source with some purpose. Not a reflex-deliberate movement. |
| M4: Withdrawal | Patient pulls away from pain | Patient moves away from the painful stimulus but doesn’t localise to it. Pulls away, not toward. |
| M3: Abnormal Flexion | Rigid arm flexion in response to pain (Decorticate) | Arms bend toward chest (looks like boxer’s pose). Indicates severe brain injury. |
| M2: Abnormal Extension | Rigid arm extension in response to pain (Decerebrate) | Both arms extend rigidly, legs extend. Indicates very severe brain stem injury. |
| M1: None | No motor response to any stimuli | Complete absence of movement, even to painful stimuli. Most severe. |
Table 3: Motor Response (M) Scoring Criteria
Critical Difference (Examiners Mark This Heavily):
M5 (Localises) vs M4 (Withdrawal) is the most commonly confused distinction.
· M5: Patient actively moves toward the pain. Apply trapezius squeeze. The patient reaches toward the stimulus, indicating localisation.
· M4: Patient pulls away without reaching toward source. Hand moves away from painful stimulus but not deliberately toward it.
Key Verbalisation:
“I’m going to apply pressure to check motor response. [Apply trapezius squeeze]. Your hand is moving up toward the source of pain-that’s localising to pain, M5. If you were just pulling away without reaching toward it, that would be M4. You’re showing purposeful movement, which is good.”
The OSCE Station Workflow: Step-by-Step (15-Minute Protocol)
The GCS station typically lasts 15 minutes and involves a scenario such as a patient who has fallen or has a suspected subdural haematoma. To pass, you must demonstrate a fluid, confident routine.
Phase 1: Preparation & Entry (0-3 Minutes)
Scene Safety, privacy and dignity & Infection Control:
1. Check bay is safe for you and the patient: scan for safety hazards or by scanning the room for who is there and how people interact with the patient “I am checking that the scene is safe for me and the patient.”
2.Provide privacy and dignity : Close the curtains or doors.
3. Perform WHO 7-step hand hygiene using alcohol gel: This is mandatory. Failing to gel your hands before touching the patient is a common infection control failure and loses marks.
Introduction & Consent:
3. “Hello, my name is [Name], and I am the nurse looking after you today. I understand you have had a fall. I need to carry out a neurological assessment to check your level of consciousness. This involves asking some questions and checking your movements. Is that alright?”
4. Identity Check: Verify patient’s Name, Date of Birth, Hospital Number against wristband. Ask the patient to state their name if able.Check for allergies verbally and on wristband.
Phase 2: GCS Assessment
Pupil size (Before GCS Scoring):
Use a pen torch. Check size (mm) and reaction (brisk/sluggish/fixed). “Pupils are 3mm and briskly reactive to light bilaterally.”
Limb Power (Asymmetry Check):
“Push against my hands, pull me towards you.” Check all four limbs for symmetry. Always note asymmetry: “Right arm has full power, left arm does not move. This asymmetry suggests possible focal neurological injury.”
Step 1: Assess Eye Opening (E)
Procedure:
1. Observe patient from a distance first. Are their eyes already open?
o If YES → Score E4 (Spontaneous) and move to verbal response
o If NO → Proceed to next step
2. Use a normal speaking voice (not shouting): “Please open your eyes for me” or “Open your eyes”
o Wait 2–3 seconds for response
o If eyes open → Score E3 (To Sound) and proceed to verbal response
o If no response → Proceed to pain stimulation
3. Apply central pain stimulus (one method; choose one):
o Trapezius Squeeze: Pinch the trapezius muscle (base of neck, where neck meets shoulder) firmly but not violently for 5 seconds
o Supraorbital Pressure: Place your thumb above the patient’s eyebrow (supraorbital ridge) and apply firm, steady pressure
4. Observe closely:
o Eyes open → Score E2 (To Pressure)
o No opening → Score E1 (None)
5. Document your finding: E = [1-4 or NT]
Examiner’s Eye:
The examiner watches whether you apply pain appropriately (not with excessive force) and whether you progress systematically (sound before pain). Skipping straight to pain loses marks.
Step 2: Assess Verbal Response (V)
Procedure:
1. Ask orientation questions in this order:
o “What’s your full name?” (Person)
o “Where are we right now?” (Place)
o “What’s today’s date?” (Time)
2. Score based on responses:
o All three correct → V5 (Oriented)
o Converses but disoriented on some aspects → V4 (Confused)
o Single words, not sentences, but intelligible → V3 (Inappropriate Words)
o Moans/groans only → V2 (Sounds)
o No response → V1 (None)
o Cannot test (intubated, etc.) → V-NT
3. If patient is intubated:
o Write: “V: NT (intubated)”
o Do NOT include in total GCS score
o Your total would be E + M only
4. Document your finding: V = [1-5 or NT]
Real Example (From OSCE Candidates):
Nurse: “Can you tell me your name?”
Patient: “My name is Michael.”
Nurse: “Good. Where are we right now?”
Patient: “I think I’m in the hospital.”
Nurse: “Yes, that’s right. What’s today’s date?”
Patient: “Um… I’m not sure. Maybe Tuesday?”
Analysis: Patient oriented to person and place, but disoriented to time = V4 (Confused)
Step 3: Assess Motor Response (M)
Procedure:
1. Start with commands (no pain yet):
o “Squeeze my hand” (hold out both hands)
o “Lift your leg” or “Push with your feet against my hand”
2. If patient obeys ANY command → Score M6 (Obeys Commands) and proceed to document
If no response → Continue to pain stimulation
3. Apply pain stimulus (use same method as eye opening for consistency):
o Trapezius squeeze OR supraorbital pressure
o Observe the patient’s response
4. Score based on what you see:
o Hand reaches toward the pain source → M5 (Localises Pain)
o Hand pulls away from pain → M4 (Withdrawal)
o Arms flex (bend toward chest) → M3 (Abnormal Flexion/Decorticate)
o Arms extend rigidly → M2 (Abnormal Extension/Decerebrate)
o No movement → M1 (None)
5. Check BOTH sides – If there’s asymmetry, note it. This suggests stroke or focal brain injury.
6. Document your finding: M = [1-6]
Common Mistake:
Don’t assume symmetrical responses. Always check both arms and legs for motor response. Asymmetry is a clinical red flag.
Step 4: Calculate Total GCS Score
Formula: GCS = E + V + M
Example Calculations:
· E4 + V5 + M6 = GCS 15 (fully awake, fully oriented, fully responsive-normal)
· E3 + V4 + M5 = GCS 12 (drowsy, confused, localising to pain-moderate brain injury)
· E1 + V1 + M3 = GCS 5 (unresponsive to all stimuli-severe brain injury)
· E3 + V-NT (intubated) + M4 = Do NOT add-instead write: E3, M4, V non-testable
Always write out the full score: “GCS 14 = E3 V5 M6” (not just “14”)
Phase 3 A-E Assessment (3-8 Minutes)
· Airway (A): “I can see/hear the patient speaking, so their airway is patent and no visual obstruction.”
· Breathing (B): Measure Respiratory Rate, rhythm and depth for a full minute,Oxygen Saturations, Respiratory noises,Unequal air entry and visual signs of respiratory distress.
· Circulation (C): Measure Blood Pressure, Pulse for a full minute, and Capillary Refill Time (CRT) less than 2 seconds, which is normal and pallor and perfusion
. Disability (D): Presence of pain,urine output and blood Glucose (Mandatory):
Address the pain of patient and ask about the urine output. A drop in consciousness can be caused by hypoglycaemia. You must verbalise: “I will check the patient’s blood glucose level to rule out hypoglycemia as a cause of altered consciousness.” Failing to do this demonstrates a lack of holistic safety awareness and loses marks.
Phase 4: Exposure & Documentation (12-14 Minutes)
· Exposure (E): Check temperature. Inspect head for injuries/bleeding if fall scenario,obtains medical history. Maintain patient dignity.
· GCS Chart Documentation (see detailed section above)
Step 5: Interpret the GCS Score & Severity
Once you have your total, the next critical step-clinical reasoning-is determining what it means.
| GCS Range | Severity | Clinical Meaning | Your Response in OSCE |
| 13–15 | Mild | The patient is awake, likely with a minor head injury or fully recovered. The risk of deterioration is lower but still possible. | “This is a mild score. I would monitor every 30 mins for 2 hours, then hourly for 4 hours, then 2-hourly, escalating if it drops.” |
| 9–12 | Moderate | The patient is drowsy/obtunded. Suggests moderate brain injury. The risk of deterioration is moderate. | “This is moderate. The patient needs 30-minute observations and careful escalation if any decline occurs.” |
| 3–8 | Severe | The patient is deeply unconscious. Severe brain injury. High risk of complications. May require an ICU. | “This is severe. I would escalate to the doctor immediately and ensure 30-minute observations with possible ICU consideration.” |
Table 4: GCS Severity Interpretation and Clinical Response
Before You Start: Set Up the Patient (Complete Version)
1. Introduce yourself – “Hi, I’m [Name], a nurse. I’m going to do a health check including some specific tests of awareness. Is that okay?”
2. Position safely – Bed elevated, side rails up if in real scenario
3. Explain what’s coming – “I’ll be checking how you respond to different things. Some may feel uncomfortable, but it won’t be painful. I’ll explain as I go.”
4. Gather equipment – Pen torch (pupils), watch (timing), observation chart, pen
Common Mistakes Nurses Make (And How to Fix Them)
| Mistake | Why It Fails | How to Fix | Impact |
| Skip systematic eye opening (jump to pain) | Shows lack of neurological understanding | Always: spontaneous → sound → pressure | High |
| Confuse M5 with M4 | Most common motor error | M5 = toward pain; M4 = away | Medium |
| Don’t assess both sides | Misses focal deficits (stroke) | Check both arms and legs | High |
| Calculate total when intubated | Invalid score | Write “V: NT” if intubated | Very High |
| No escalation of abnormal findings | Misses clinical reasoning requirement | Always escalate abnormal GCS | Very High |
| Rush assessment | Appears unpractised | Take 5-7 minutes, quality over speed | Medium |
| Document poorly | Can’t see your thinking | Write date, time, E-V-M, total, initials | High |
| Use outdated GCS chart | Looks unprepared | Download latest NMC chart | Medium |
| Fail to explain to patient | Violates 2026 person-centred care | Explain findings and monitoring plan | Medium |
Table 5: Common GCS Assessment Mistakes and Solutions
Real OSCE Scenario: What a ‘Pass’ Looks Like
Scenario: You’re assigned the Assessment Station. Patient is Mrs. Patel, 68, who fell at home and was brought to hospital. She’s drowsy and confused. As part of your assessment, please complete an A to E assessment (airway, breathing, circulation, disability, exposure), and take and record the patient’s vital signs (blood pressure, temperature, pulse rate, oxygen saturations, respiratory rate) and calculate Glasgow Coma Scale(GCS)score
You have 20 minutes to complete this station, including the completion of the following documentation: Neurological Observations GCS chart.
The Pass Approach (Examiner’s Perspective):
Nurse: “Good morning, Mrs. Patel. I’m [Name], a nurse. I’m going to do your A-E assessment along with Neurological Assessment. Is that okay?”
Patient (drowsy): “Yes… okay…”
Nurse: “I notice your eyes are closed. [Calls out] Mrs. Patel, please open your eyes for me.”
Patient: [Opens eyes slowly]
Nurse: “Good. Your eye opening is spontaneous. [Checks orientation] Can you tell me your full name?”
Patient: “I’m Margaret Patel.”
Nurse: “Perfect. Do you know where you are right now?”
Patient: “I’m… in the hospital, I think. But I’m not sure which one.”
Nurse: “You’re in [Hospital Name], which is correct-you’re oriented to place. What year is today?”
Patient: “I think it is 2022?”
Nurse: “You are little confused, you are currently in 2026. No worries. Will escalate to the medical team. Now I’m going to check your motor response. Can you please lift your arm?
Patient: [Lift’s hand]
Nurse: “Excellent. You’re obeying commands. Let me just check the other side. [Applies gentle pressure] Your hand is moving up toward where I’m pressing-that’s good. I will put some pressure to your legs as well, [Applies gentle pressure] Your legs are moving up toward where I’m pressing-that’s good. Both your limps are having normal power.
I will check pupil size, is that okay?
Patient: Yes
Nurse: [Check pupil size with PEN], The pupil size are 3, now I will check the pupil response. [ Light the pen torch from outer canthus to the inner canthus. Both are reactive
Nurse [Verbalises findings]: “Mrs. Patel, based on my assessment, your Glasgow Coma Score is 14-that’s E4 for opening eyes spontaneously, V4 for being confused about time, and M6 for obeying commands. This indicates a mild neurological status, but given your fall, we’ll keep a close eye on you. I’m going to check these vital signs every 30 minutes until we achieve a GCS score 15, after that will monitor you every 30 minutes for 2 hours, every hourly for 4 hours and then every 2 hourly. I’ll escalate to the medical team also. Do you have any questions?”
[Nurse documents clearly on GCS chart: E4 V4 M6 = GCS 14, date, time, initials]
Why This Passes (Examiner Checklist):
✅ Systematic progression (spontaneous → sound for eye opening)
✅ Complete assessment of all three components
✅ Explanation to patient (person-centered care)
✅ Correct scoring (E4 V4 M6 = GCS 14)
✅ Interpretation of severity (mild = good prognosis)
✅ Escalation plan (30-minute observations, alert if changes)
✅ Clear documentation with date, time, full score breakdown, and initials
✅ Professional communication and clinical reasoning demonstrated
Frequently Asked Questions (FAQ)
How do I know if I should use trapezius squeeze or supraorbital pressure?
Both are acceptable. Choose whichever you’re comfortable with and use it consistently throughout the exam. Trapezius squeeze is often easier on the patient (less uncomfortable).
What if the patient is intubated in my scenario?
Do NOT score verbal response. Write “V: NT (Not Testable)” on the chart. Calculate GCS as E + M only. For example, E3 M5 with V non-testable = do not write GCS 8. Instead, document: “E3, M5, V non-testable.”
Is a GCS of 14 considered normal?
GCS 15 is fully normal. GCS 14 is mild-still generally good but suggests minor impairment, possibly slight confusion or minor drowsiness. Any score of 13 or below requires monitoring.
What’s the difference between V3 (Inappropriate Words) and V4 (Confused)?
V4 (Confused): Patient converses but is disoriented. They speak in sentences, follow conversation, but answers don’t match reality.
V3 (Inappropriate Words): Patient speaks individual words but they don’t fit the conversation.
V4 is less severe than V3.
If GCS drops from 15 to 13, do I escalate immediately?
Yes. Any decrease in GCS is significant and should trigger escalation, even if 13 is still “mild.” The change matters as much as the absolute score.
Should I calculate NEWS2 score along with GCS?
In real Assessment Station scenarios (ABCDE approach), No- We need to calculate GCS only. There are columns to record the vitals in the GCS chart itself
What if I can’t complete the assessment because the patient is too confused or agitated?
Document what you can assess and note limitations. E.g., “Patient very agitated, unable to assess verbal orientation fully. E2 M4 documented; GCS partial score due to patient condition.”
However, for normal OSCE Scenario we won’t get agitated patient.
How often should I reassess GCS in the real clinical setting?
· GCS 15: Every 30 minutes for 2 hours, then hourly for 4 hours, then 2-hourly
· GCS 14 or below: Every 30 minutes until stable/ till achieve a GCS score of 15
· GCS 8 or below: Hourly, with possible ICU escalation
· Any decline: Escalate immediately
Key Takeaways: Your GCS Mastery Summary
1. GCS is three separate assessments: Eye (1-4), Verbal (1-5), Motor (1-6). Total range: 3-15.
2. Always progress systematically: For eye opening, try spontaneous → sound → pain. Never skip steps.
3. Interpretation matters as much as scoring: A GCS of 12 means moderate brain injury; you must respond with appropriate monitoring frequency and escalation.
4. M5 (Localises) vs M4 (Withdrawal): Most commonly confused distinction. M5 = purposeful movement toward pain. M4 = pulling away.
5. If intubated, write “V-NT”: Don’t calculate a total score. Document E and M separately.
6. Document fully: Date, time, E-V-M breakdown (e.g., E3 V4 M5), total (12), and initial it.
7. Communicate findings: Explain the score and your monitoring plan to the patient. 2026 NMC standards emphasise person-centred care.
8. Link to escalation: If GCS is 8 or below, or has decreased from baseline, escalate immediately.
9. Use the current NMC chart: Download from NMC Test of Competence support documents.
10. Practice with real scenarios: Complete at least 20 full neurological assessments (including GCS) under timed conditions before your exam.
