All Defence Exam Eligibility Checker (India)

What is Defence Exam Eligibility and Why It Confuses Everyone

India has some of the most respected armed forces in the world — the Indian Army, Navy, and Airforce — along with powerful paramilitary forces like CRPF, BSF, CISF, and ITBP. Every year, lakhs of young Indians dream of serving the nation in uniform. But the first hurdle everyone faces is the same: am I even eligible to apply?

The confusion is real. India's defence recruitment system has more than 15 different entry schemes, each with its own age limit, height requirement, education qualification, and marital status rule. NDA eligibility is different from CDS eligibility. Agniveer rules are different from SSC GD rules. And then there are gender-wise differences on top of all that.

This is exactly why the defence exam eligibility checker india tool was needed — to put all the criteria in one place and give you a clear answer in seconds.

NDA — National Defence Academy

The NDA is the most prestigious entry for defence aspirants. Conducted by UPSC twice a year, it leads to a commission as an officer in the Indian Army, Navy, or Airforce after 3 years of training at the National Defence Academy in Khadakwasla, Pune.

NDA eligibility key points: You must be between 16.5 and 19.5 years of age. You must be unmarried. For Army wing, 12th pass in any stream is acceptable, but for Navy and Airforce wings, you must have Physics and Mathematics in 12th. The minimum height is 157 cm. This exam is only for male candidates as of 2026 (Supreme Court has allowed female candidates, implementation ongoing).

The biggest beginner mistake is checking for NDA after turning 19.5 — the window is narrow, so you must start preparing in class 11 itself. Always verify nda cds afcat eligibility criteria 2026 from official website par before applying.

CDS — Combined Defence Services

CDS is the officer-level entry for graduates. Also conducted by UPSC twice a year, it leads to selection for IMA (Army), INA (Navy), AFA (Airforce), and OTA (Officers Training Academy for SSC commission).

CDS eligibility key points: Age range is 19–25 years (varies by wing). Minimum qualification is graduation in any stream — but for Airforce and Navy, technical/science background is preferred. The OTA entry is open to graduates of any stream. Marital status restriction applies for Airforce and Navy entries only.

CDS is often overlooked by commerce and arts graduates who think defence is only for science students — but OTA entry at CDS is open to all graduates. This is one of the most important facts for army navy airforce eligibility kaise check kare purposes.

AFCAT — Air Force Common Admission Test

AFCAT is the Indian Airforce's own entry scheme for Flying Branch, Ground Duty (Technical), and Ground Duty (Non-Technical) branches. It is conducted twice a year.

AFCAT eligibility key points: Age is 20–26 years. Minimum 60% marks in graduation is required. For Flying Branch, Physics and Mathematics in 12th is mandatory. Height minimum is 162.5 cm for male candidates. Correctable vision is acceptable for non-flying branches.

SSC GD — Staff Selection Commission General Duty

SSC GD is the entry for Constable General Duty post in paramilitary forces — CRPF, BSF, CISF, ITBP, SSB, NIA, SSF, and ASSAM Rifles. It is one of the most applied defence exams in India.

SSC GD eligibility key points: Age range is 18–23 years (relaxation for reserved categories). Minimum education is only 10th pass — making it accessible to the widest pool of candidates. Height requirement is 170 cm for male (General), 157 cm for female. No marital restriction applies here. This makes SSC GD the most inclusive defence exam in India.

Agniveer — Army, Navy, Airforce

The Agniveer scheme, introduced in 2022 under the Agnipath scheme, allows youth to serve in the armed forces for four years as Agniveers, with 25% being retained for regular service. It covers Army (5 posts), Navy (2 posts), and Airforce (1 post).

• Agniveer GD: 10th pass (45% aggregate, 33% each subject), age 17.5–21 years, height 170 cm
• Agniveer Clerk/Store Keeper Technical (SKT): 12th pass (60% overall, 50% each subject), age 17.5–21, height 162 cm
• Agniveer Technical: 12th Science with Physics, Chemistry, Maths (50% marks), age 17.5–21
• Agniveer Nursing Assistant (NA): 12th Science with Physics, Chemistry, Biology (50% marks)
• Agniveer Toposurvey: 12th with Maths and Science subjects

The Agniveer scheme has brought defence services closer to youth from rural and semi-urban areas. Agniveer eligibility kya hai is one of the most searched questions in India. Always verify age cut-off dates from official website par before applying.

CAPF AC — Central Armed Police Forces Assistant Commandant

CAPF AC is an officer-level entry conducted by UPSC for BSF, CRPF, CISF, SSB, and ITBP in the Assistant Commandant rank. Age range is 20–25 years. Graduation in any stream is required. Height minimum is 165 cm for male.

JCO — Junior Commissioned Officer (Religious Teacher / Pandit)

JCO Religious Teacher entry is unique — it is for candidates with religious qualifications (Sanskrit/Urdu/Gurbani etc.) who can serve as Pandits, Maulvis, Granthi, Padri, etc. in the Army. Age range is 27–34 years, and graduation along with relevant religious qualifications is required. Height minimum is 157 cm.

Havaldar — Education and Surveyor

Army Havaldar Education posts require graduation (B.Ed preferred) and are for candidates aged 20–25 years. Army Havaldar Surveyor requires 12th with Mathematics and Science. These are technical support roles within the Army structure.

Common Beginner Mistakes in Defence Exam Eligibility

• Applying for NDA after age 19.5 — the window is strict
• Not knowing that CDS OTA is open to all graduates including Arts/Commerce
• Assuming AFCAT requires engineering — 60% graduation in any stream qualifies for Ground Duty
• Forgetting that SSC GD has a very strict height requirement of 170 cm for male
• Thinking Agniveer is only one post — there are 5+ posts with different education requirements
• Not checking the medical eligibility (eye standards especially for AFCAT Flying)

How to Choose the Best Defence Exam for You

The best defence exam for you depends on three things: your age, your education, and your physical fitness. Here is a simple decision guide:

• If you are in 11th–12th (Science with Maths): Start NDA preparation immediately — it is the earliest and most prestigious entry
• If you just passed 10th: Aim for SSC GD and Agniveer GD simultaneously
• If you are a graduate in any stream: CDS (OTA) and CAPF are your primary targets
• If you are a graduate in Science/Engineering: CDS (Army/Navy/AF), AFCAT, and technical Agniveer posts all apply
• If you are 25–34 years old: JCO Religious Teacher is a unique opportunity if you have religious qualifications

Physical Preparation is Just as Important as Written Exam

Many candidates crack the written exam but fail at the physical fitness test, medical board, or SSB interview. Simultaneously preparing your physical fitness — running, push-ups, pull-ups, swimming — is absolutely essential for any defence exam. Running timing for SSC GD is 1.6 km in 5.45 minutes for male candidates aged 18–23. Prepare from day one.
