Central Armed Police Forces constable recruitment — General Duty through SSC and tradesman posts directly by forces such as BSF, CISF and ITBP — is matriculation-level, high-volume and unusually demanding because two different kinds of preparation must advance together. You need a solid score on a short objective written paper, and you need the body and measurements to survive qualifying physical stages that never appear on the merit sheet but still end many candidacies.
This guide covers the common CAPF constable pipeline: written or computer-based test, Physical Efficiency Test and Physical Standard Test, trade test where the post is tradesman, document verification and detailed medical examination. Always confirm the exact stage order in your notification — some cycles conduct PET/PST before the written paper, while SSC GD typically runs the Computer Based Examination first.
Who recruits, and which exam you are sitting
| Route | Typical posts | Where to confirm |
|---|---|---|
| SSC GD Constable | GD constables in BSF, CISF, CRPF, ITBP, SSB and other CAPFs | Staff Selection Commission notification |
| Force tradesman recruitment | Constable (Tradesman) — cook, barber, electrician and similar trades | BSF, CISF or ITBP recruitment portal |
| Force GD recruitment | ITBP and other force-specific GD constable cycles | Respective force recruitment site |
If your goal is a General Duty constable berth in a CAPF, SSC GD is the main national route — see the full pattern on the SSC GD Constable exam page. For tradesman posts, prepare through the force that notified the vacancy: BSF Constable (Tradesman), CISF Constable (Tradesman) and ITBP Constable each publish their own timelines and stage sequence.
The written paper: four familiar sections
Whether the mode is Computer Based Test or OMR, matriculation-level CAPF constable written exams usually split marks across the same four blocks. SSC GD Constable is the reference many candidates know:
| Section | SSC GD (CBE) | Typical force tradesman pattern |
|---|---|---|
| General Intelligence / Reasoning | 20 questions, 40 marks | Often 25 questions, one mark each |
| General Knowledge / Awareness | 20 questions, 40 marks | Often 25 questions, one mark each |
| Elementary Mathematics | 20 questions, 40 marks | Often 25 questions, one mark each |
| English / Hindi | 20 questions, 40 marks | Often 25 questions, one mark each |
Elementary Mathematics stays at Class-10 level — percentages, ratio, averages, simple interest, time and work, and basic mensuration. Reasoning favours series, coding-decoding, blood relations and classification rather than heavy puzzles. General Awareness rewards a compact static note plus recent current affairs; build that habit with general awareness for railway and SSC.
For the language section, choose the medium you read fastest in and keep grammar steady — the preparation habits in English section best practices apply even when you attempt Hindi, because the question types — comprehension, cloze-style gaps, error spotting — are parallel.
Negative marking: read the notification
SSC GD applies 0.25 marks deducted for each wrong answer on questions worth two marks. That penalty is small but compounds over eighty questions, so attempt mainly where you can eliminate options — the discipline is spelled out in negative marking strategy. Recent BSF and CISF tradesman advertisements have often stated no negative marking on the hundred-mark written paper, which changes how aggressively you can attempt borderline questions. Never assume the rule from a previous cycle; open the PDF for yours.
Physical Efficiency Test and Physical Standard Test
PET and PST are qualifying in standard CAPF constable recruitment. They do not add to merit, but you cannot be appointed without clearing them.
- PET is usually a timed run; distance and qualifying time depend on gender and sometimes region. Treat it as a training target months before admit cards appear.
- PST checks height, chest expansion (where applicable for male candidates) and weight against force tables. Measure yourself against the notification before you pay the fee — these thresholds are not negotiable on test day.
Because thousands fail here despite strong written scores, run and jump practice belongs in week one, not after the written result.
Trade test, document verification and medical examination
Tradesman posts add a trade test after documentation: practical skills in the trade you applied for (for example cookery, barber work or electrical basics). Your ITI or experience matters, but so does calm performance under observation — rehearse the trade tasks the notification describes.
Document verification matches originals to your application — education certificates, category claims, trade certificates and identity proofs. Discrepancies discovered here are as final as a failed run.
The detailed medical examination follows CAPF medical standards under Ministry of Home Affairs guidelines. Vision, hearing, chronic conditions and fitness for field duty are assessed. It is qualifying, yet it is the last gate before appointment.
Where the selection is actually won
Physical stages filter; the written score (and trade test where it counts toward merit) is what orders the list among those who qualify everywhere else. That is why most successful candidates spend the majority of study hours on the four written sections, while still logging kilometres on the track every week.
A practical split:
- Daily: thirty to forty-five minutes of General Awareness revision and a short reasoning or maths set under a timer.
- Three to four weekly runs progressing toward the PET distance in your notification.
- One weekly review of mistakes from practice papers — accuracy matters more than attempt count when negative marking applies.
Structure the months with how to build a study plan, and keep awareness current through the daily quiz.
Practice that transfers
Rehearse under exam conditions on the page for the recruitment you are targeting — SSC GD mocks and syllabus on the exam page, or the tradesman exam that matches your trade notification. When the written and physical halves both advance together, you arrive at each stage already prepared for the one after it, instead of restarting fitness or syllabus coverage every time a result is declared.

Frequently asked questions
What usually decides the final merit in CAPF constable recruitment?
Once you clear the qualifying physical and medical gates, the written examination score is what ranks candidates for appointment in most cycles — SSC GD uses the Computer Based Examination alone for merit, while force tradesman notifications typically combine written performance with the trade test. Physical tests are qualifying in almost every CAPF constable pipeline, so they filter who reaches the merit list but rarely add marks to it.
Should I start physical training only after the written exam?
No. PET runs and PST height, chest and weight standards eliminate a large share of applicants every cycle, and the gap between a written result and physical tests is too short to build stamina from zero. Start running and checking your measurements against the notification table from day one, in parallel with book work.
Is negative marking the same in every CAPF constable written test?
No. SSC GD Constable deducts 0.25 marks per wrong answer on a two-mark question, while many force-level tradesman written papers in recent notifications carried no negative marking at all. Read the advertisement for your cycle before you shape your attempt strategy.
