Must Read - When is the NDA Exam Conducted?

What is an NDA medical exam?

The NDA medical examination is one of the most rigorous fitness screenings in India. Conducted at designated Military Hospitals after SSB recommendation, it covers vision, hearing, flat feet, knock knees, dental health, skin conditions, and more. The blunder NDA aspirants make–they put their entire focus on collecting the best NDA exam preparation booksfor the written exam, which is not bad, but neglecting their physical health initially is something they have to pay for later on.

The purpose of the NDA medical test 2026 is not to reject candidates, but to ensure that future officers are physically capable of handling the demanding lifestyle, training conditions, and responsibilities of the Armed Forces. Here are the NDA physical standards parameters on which the candidates are tested to choose the absolute best from the rest:

• Vision and eyesight standards
• Hearing ability
• Height and weight measurements
• Flat feet and knock knees
• Dental and oral health
• Spine and posture
• Skin conditions and allergies
• Chest expansion and respiratory health
• Overall physical and mental fitness

Detailed Breakdown of NDA Medical Test 2026

The medical board is conducted at the nearest Armed Forces Military Hospital after SSB results are declared. It usually takes place for 4 to 5 days and is under the vigilance of a panel of specialist service medical officers. Before the actual medical testing drill begins, NDA aspirants need to fill the AFMSF-2  form (Armed Forces Medical Services Form-2), the official medical history document that organises all specialist investigations.

Step 1– Registration at the Military Hospital

NDA aspirants are assigned a medical chest number with a red cross insignia, which they need to wear at all times on campus. A Staff Surgeon will guide the candidates to fill the AFMSF-2 form, which records personal details, complete medical history, and any pre-existing conditions.

Step 2– Day-by-Day Medical Examinations

Day 1: The first day is entirely dedicated to laboratory and imaging investigations, which include a blood test, urine test, X-ray, and ultrasound. Candidates must fast before Day 1 testing; they need not eat anything before reporting on the first morning.

Day 2: The entire second day is dedicated to ophthalmological assessment. Uncorrected vision must be 6/6 in one eye and 6/9 in the other. Colour vision is tested using the Ishihara chart — any deficiency is typically disqualifying for most NDA branches. Candidates with glasses are also assessed for post-correction acuity, and a fundus examination checks the health of the retina. Eat foods rich in Vitamin A and antioxidants in the weeks before.

Day 3: This day is booked for ENT examination ( Ear, Nose, Throat). The audiometry test checks hearing sensitivity at multiple frequencies — even minor loss at higher frequencies can be flagged. The nasal passages are examined for deviated septum (DNS); a minor deviation without functional impact may be acceptable, but significant DNS usually requires a surgical history. Tonsil enlargement and overall throat health are also assessed.

Day 4: The primary focus is on the surgical and systemic examination, where doctors assess posture, spine alignment, flat feet, knock knees, bow legs, chest expansion, blood pressure, BMI, and overall cardiovascular fitness.

Day 5: The final day includes a dental examination to assess oral health, missing teeth, decay, and bite alignment. After all specialist assessments are completed, the Medical Board reviews the overall medical profile and declares candidates as Fit, Temporary Unfit, or Permanent Unfit. Female candidates additionally undergo a gynaecological examination as per AFMS guidelines.

Step 3– Medical Board Outcomes

There can be 3 possible outcomes after the board conference–Fit, Temporary Unfit, & Permanent Unfit.

Step 4– The Appeal & Review Process

Being declared medically unfit is not always the end of the journey. Candidates have a structured three-level appeal system available.

Special Medical Board (SMB)

This is the initial medical board conducted during the 4–5 day examination process at the military hospital. It gives the first fitness decision.

Appeal Medical Board (AMB)

Candidates declared permanently unfit can apply for an AMB within 42 days by paying the prescribed fee. The examination is conducted at designated Command Hospitals across India.

Review Medical Board (RMB)

If a candidate is again declared unfit in the AMB, a final appeal can be made through the RMB. The decision of the RMB is considered final.

Top 6 Reasons For Medical Rejection

• Poor Eyesight & Refractive Errors: Out of all NDA physical standards, vision criteria are way too strict. High myopia, hypermetropia, or colour blindness lead to frequent rejection.
• Flat Feet (Pes Planus): The armed forces look for a healthy arch to ensure candidates are fit for physical training and field duties. Grade II and Grade III flat feet typically lead to outright rejection.
• Underweight or Overweight BMI: To match the NDA eligibility criteria in terms of medical conditions, aspirants are asked to maintain a perfect height-to-weight ratio, otherwise declared unfit.
• Hearing Deficiency: Hearing is tested in both ears. Even minor loss in higher frequencies can result in rejection, particularly for technical branches.
• Skin Conditions: Tattoos, while not always disqualifying, must be within permissible size and location limits as per the latest notification. Psoriasis, severe acne, eczema, and chronic dermatological conditions are commonly flagged.
• Dental Issues: Missing teeth, poor alignment, and significant decay can result in rejection or a temporary unfit category pending corrective treatment.

How to Avoid NDA Medical Rejection in 2026

Many medical rejections can be avoided through early preparation and regular health monitoring. Follow these simple steps:

• Get a full medical check-up early to identify and correct any issues well before the NDA selection process.
• Maintain good eyesight through regular eye examinations and a healthy diet rich in Vitamin A.
• Stay within the prescribed height-weight standards by following a balanced diet and exercising regularly.
• Monitor foot and leg health to detect flat feet or knock knees at an early stage.
• Protect your hearing by avoiding excessive noise exposure and treating ear infections promptly.
• Maintain good dental hygiene and address cavities, gum problems, or alignment issues in advance.
• Treat skin conditions early and follow the Armed Forces' guidelines regarding tattoos.
• Keep medical records ready for any past treatments or surgeries.
