Border Security Force RO

BSF RO is a recruitment exam conducted by Border Security Force, relevant to candidates preparing for the armed forces and paramilitary recruitment.

The BSF HC RO RM recruitment fills Head Constable (Radio Operator) and Head Constable (Radio Mechanic) posts in the Communication Setup (Telecom) cadre of the Border Security Force. The current cycle began with the August 2025 notification for 1,121 vacancies, and the physical stage was held between December 2025 and March 2026.

Dates marked reported come from secondary coverage, so confirm them on rectt.bsf.gov.in and in your registered email. Several pages currently quote CBT dates of 1 to 3 September 2026. The BSF notice behind those dates covers Head Constable (Ministerial), ASI (Steno) and other non-GD posts advertised in 2024, so do not assume it applies to Radio Operator and Radio Mechanic.

Vacancy details

Of the vacancies for direct recruitment, 10% are reserved for ex-servicemen and 5% for compassionate appointment. The remaining 25% of all vacancies go to serving BSF Constables (GD and Tradesman) through the departmental exam (LDCE).

The notification says the numbers may rise or fall for administrative reasons, so treat them as indicative until the final result.

Eligibility criteria

You can check the complete rules on the BSF RO RM eligibility page. The essentials are below.

Educational qualification

Both posts accept either of two routes:

  • Class 12 route: 10+2 with Physics, Chemistry and Mathematics from a recognised board, with at least 60% marks in PCM as a regular student.

  • ITI route: Class 10 pass plus a two-year ITI certificate. For Radio Operator the trades include Radio and Television, Electronics, Computer Operator and Programming Assistant, Data Preparation and Computer Software, General Electronics and Data Entry Operator. For Radio Mechanic the list is wider and also includes Electrician, Fitter, Communication Equipment Maintenance, Computer Hardware, Network Technician and Mechatronics.

Age limit and relaxation

Age is counted as on 23 September 2025. The lower limit is 18 years for everyone.

The window for this cycle closed on 23 September 2025, so the steps below show what to expect in the next BSF notification. A candidate who qualifies for both posts could apply separately, with a separate fee, for each.

  1. Register on rectt.bsf.gov.in with your personal details, mobile number and email ID, and note the registration ID and password.

  2. Log in and fill the form: basic details, address, qualification and physical measurements in centimetres.

  3. Upload your photograph, signature and thumb impression (about 50 KB each).

  4. Pay the fee online if it applies to you, then save a printout of the submitted form.

Selection process

Selection runs in three phases, and each phase is qualifying before the next begins.

  1. Phase I: Physical Standard Test (PST) and Physical Efficiency Test (PET). Both are qualifying.

  2. Phase II: Computer based test (CBT) of 200 marks. Candidates for Phase III are shortlisted by CBT merit, up to six times the vacancies, with separate category-wise lists for RO and RM.

  3. Phase III: Document verification, dictation and paragraph reading test (Radio Operator only), then detailed medical examination.

Ex-servicemen and LDCE candidates are exempt from the PST and PET.

The PET is recorded through RFID, and you must clear all three events. Some pages show the jumps in metres, so check the official notification PDF for exact figures before you train for them.

The medical examination later checks distant vision without correction, colour vision, flat feet, knock-knees and general fitness. Candidates found unfit can appear for a review medical examination.

CBT exam pattern and final merit

The CBT is one common paper for both posts, set at 10+2 level in English and Hindi.

Each correct answer earns 2 marks and each wrong answer costs 0.25 marks. Minimum qualifying marks are 38% for General, OBC and EWS (76 marks), 33% for SC and ST (66 marks), and 20% for compassionate appointment candidates (40 marks).

What this means for you

  • Physics decides the paper: It carries 80 of 200 marks, so a weak Physics score is hard to recover elsewhere.

  • A wrong guess is expensive: You lose the 2 marks you could have scored and 0.25 more, a swing of 2.25 marks. Attempt a question only after you have removed at least one option.

  • Qualifying is not selecting: Clearing 76 marks only keeps you in the race. Shortlisting depends on where you stand among candidates in your category.

Dictation test and final merit

Radio Operator candidates face a 50-mark English dictation test, with deductions for each letter or word mistake, plus a qualifying paragraph reading test. Qualifying marks follow the same 38%, 33% and 20% scheme.

For example, an RO candidate who answers 70 questions correctly and 20 wrongly scores 140 minus 5, which is 135 in the CBT. With 40 in dictation, the merit score is 175 out of 250.

Syllabus summary

BSF names the subjects and level but does not publish a topic-wise list. The topics below are a working checklist built from the 10+2 level stated in the notification, so use them as a guide rather than an official list.

Mechanics, heat, optics, electricity and magnetism, modern physics, basic electronics

Electricity and mechanics numericals

Mathematics

Algebra, trigonometry, coordinate geometry, calculus basics, vectors

Admit card

BSF issues a separate e-admit card for each phase, at least three days before the test, and informs candidates by SMS, email and the recruitment website. You need your own login, so keep your registration details safe.

How to download the admit card

  1. Open rectt.bsf.gov.in.

  2. Click the admit card link shown for HC (RO) and HC (RM).

  3. Log in with the credentials you created while registering.

  4. Check the card on screen, download it and take a clear printout.

Details to verify on the card

Check your name, roll or registration number, category, date of birth, photograph and signature, exam date, shift, reporting time and the instructions. If anything is wrong, contact BSF at once. Carry the printed admit card and a valid photo ID, because entry can be refused without them.

Salary and allowances

Details

Pay level

Level 4, 7th CPC

Pay scale

Rs. 25,500 to Rs. 81,100 per month

Allowances

Dearness allowance, ration money, dress allowance, border-area special compensation, transport, LTC, and free accommodation or HRA

The notification also covers pension under the scheme it names. In-hand salary varies with posting and allowances. Some pages quote a Level 3 scale, so rely on the official notification.

How to prepare

The CBT is a Class 12 level paper under a time limit, so preparation is mostly about speed on Physics and Mathematics numericals.

  • Weeks 1 to 6: Revise NCERT Physics, Chemistry and Mathematics, and read one current affairs digest each day.

  • Weeks 7 to 10: Take topic-wise tests, especially in Physics, and keep an error log.

  • Final phase: Take full-length 2-hour mocks, analyse them the same day and revise the error log. Radio Operator aspirants should add daily English dictation and reading practice.
