Eligibility Criteria
Indian citizens only.
Age on 1 July 2025
18 to 27: born between 2 July 1998 and 1 July 2007.
| Category | Relaxation or upper limit |
|---|---|
| SC and ST | up to 5 years |
| OBC | up to 3 years |
| Widows, divorced women and women judicially separated and not remarried (Unreserved or EWS) | up to 35 years of age |
| The same categories (OBC) | up to 38 years of age |
| The same categories (SC or ST) | up to 40 years of age |
| Departmental candidates of Delhi Police with not less than 3 years' regular and continuous service as on the closing date (Unreserved or EWS) | up to 40 years of age |
| The same (OBC) | up to 43 years of age |
| The same (SC or ST) | up to 45 years of age |
Ex-servicemen get 3 years after deducting military service.
Qualification, by the closing date
- 10+2 with Science and Mathematics from a recognised board, or
- a National Trade Certificate in Mechanic-cum-Operator Electronic Communication System.
Arts or commerce 10+2 doesn't qualify. Your result must have been declared, not just processed, by the closing date. Distance learning qualifications count only if the UGC's Distance Education Bureau recognised them for the period you studied.
You'll also need to pass a computer test later: 1,000 key depressions in 15 minutes in English, plus basic computer functions.
No relaxations beyond the Standing Order and the Delhi Police (Appointment and Recruitment) Rules, 1980. No PwD reservation.
Sons and daughters of serving, retired or deceased Delhi Police staff (not dismissed or removed as a penalty) get 5 cm off the height standard, and sons 5 cm off chest. Those who are also SC, ST, OBC or from a hill area must pick one relaxation.
Selection Process
SSC runs the notice, applications and the CBE. The Delhi Police runs everything after: PE&MT, trade test, computer test, documents, medical, vacancies and the reserve panel. Complaints about those stages go to the Delhi Police.
Candidates up to twenty times the vacancies in each category are called to the PE&MT, plus everyone tied on the cut-off.
Physical Endurance Test, at Delhi only
Race first, then long jump and high jump, three chances each.
| Age | Race, 1600 metres | Long jump | High jump |
|---|---|---|---|
| Up to 30 years | 7 minutes | 12 feet 6 inches | 3 feet 6 inches |
| Above 30 to 40 years | 8 minutes | 11 feet 6 inches | 3 feet 3 inches |
| Above 40 years | 9 minutes | 10 feet 6 inches | 3 feet |
| Age | Race, 800 metres | Long jump | High jump |
|---|---|---|---|
| Up to 30 years | 5 minutes | 9 feet | 3 feet |
| Above 30 to 40 years | 6 minutes | 8 feet | 2 feet 6 inches |
| Above 40 years | 7 minutes | 7 feet | 2 feet 3 inches |
No appeal against failing any of the three. An earlier disqualification in this exam stands even if you hide it and pass later. Pregnant women, or those within six months of a delivery or 45 days of a miscarriage, are declared temporarily unfit, their result held in a sealed cover with the vacancy reserved, and re-tested six weeks after confinement ends.
Physical measurement
| Standard | Male candidates |
|---|---|
| Height | 170 cm, relaxable by 5 cm |
| Chest | 81 cm to 85 cm, with a minimum of 4 cm expansion, relaxable by 5 cm |
| Standard | Female candidates |
|---|---|
| Height | 157 cm, relaxable by 5 cm |
| Chest | not prescribed |
The 5 cm relaxation applies to hill-area residents (Garhwalis, Kumaonis, Gorkhas, Dogras, Marathas, and people from Sikkim, the North-East states, Himachal Pradesh, Kashmir and Leh and Ladakh, with a certificate from the DC, DM, SDM or Tehsildar) and to wards of Delhi Police staff (certificate from the DCP, Additional DCP or ACP). Height and chest can be appealed, with re-measurement the same day.
Trade test
Dictation in Hindi and English: more than 50 per cent mistakes in either disqualifies. Reading a passage aloud in both languages, videographed. It's compulsory.
Computer proficiency test
Type a 200-word English passage in MS Word at 1,000 key depressions in 15 minutes, judged on accuracy, and show basic functions: opening and closing a PC, printing, MS Office, saving and editing text, paragraphs and numbering.
Medical
Better eye 6/6 without glasses; worse eye 6/36, correctable to 6/9 or 6/12.
Final list
Drawn category-wise on CBE marks plus bonus marks alone. SC, ST and OBC candidates selected on merit without relaxed standards take unreserved seats. SSC also prepares a 15 per cent reserve panel, sent to the Delhi Police in a sealed cover and not published.
Salary
Group 'C', Pay Level-4 of the 7th CPC matrix: ₹25,500 to ₹81,100. ₹25,500 is the starting basic pay, before DA, Delhi HRA, transport allowance and Delhi Police allowances, and before NPS and health scheme deductions. The notice gives only the pay level.
The posting is in the Delhi Police, handling police communications.
How to Apply
Apply online at ssc.gov.in; a notice also appears on delhipolice.gov.in. Toll-free helpline 180 030 930 63.
| Step | Date |
|---|---|
| Notice uploaded on the Commission's website | 24 September 2025 |
| Submission of the online application form | 24 September to 15 October 2025 |
| Last date and time for receipt of the online application form | 15 October 2025, 23:00 |
| Last date and time for online fee payment | 16 October 2025, 23:00 |
| Window for Online Application Form Correction, with correction charges | 23 to 25 October 2025, 23:00 |

Fee ₹100. Women, SC, ST and ex-servicemen eligible for reservation pay nothing. Pay online by BHIM UPI, net banking, or Visa, MasterCard, Maestro or RuPay debit card. Check Payment Status in your login: if the fee didn't arrive, the form says "Incomplete" and is rejected. No refunds.
Before applying, check your 10+2 has Science and Mathematics. NCC or RRU certificates must exist by the closing date, and the originals are needed at the PE&MT; ex-servicemen don't get the NCC bonus. Category certificates must follow the notice's formats. False category claims get you barred from SSC exams.
Participating Institutes
The employer is the Delhi Police. The recruitment runs under its Standing Order No. HRD/06/2022 and an MoU with SSC. SSC publishes the vacancies the Delhi Police reports and has no say in them or the reservation roster.
The notice advertised 370 male and 182 female posts. The revised position of 25 February 2026:
| Head Constable (AWO/TPO), Male | UR | EWS | OBC | SC | ST | Total |
|---|---|---|---|---|---|---|
| Open | 100 | 24 | 63 | 25 | 14 | 226 |
| Departmental | 13 | 3 | 8 | 3 | 2 | 29 |
| Ex-servicemen | 13 | 3 | 8 | 10 | 8 | 42 |
| Total | 126 | 30 | 79 | 38 | 24 | 297 |
| Head Constable (AWO/TPO), Female | UR | EWS | OBC | SC | ST | Total |
|---|---|---|---|---|---|---|
| Open | 56 | 13 | 35 | 17 | 11 | 132 |
| Departmental | 6 | 1 | 4 | 2 | 1 | 14 |
| Total | 62 | 14 | 39 | 19 | 12 | 146 |
Departmental posts are filled from confirmed Delhi Police Constables, not open applicants. Ex-servicemen get 10 per cent, on the male side only.
Exam Centres
The CBE is held across India, in Hindi and English, with centres based on where applications come from. You choose centres in the form and can't change them later; SSC can move you. In 2025 SSC offered self slot selection for the four Delhi Police exams on 4 December 2025.
The PE&MT is in Delhi only, at three centres including the Delhi Police Academy, and so are the trade test, computer test, documents and medical. On PE&MT day you report to a holding area, wear an RFID tag for the race, and have your documents collected and checked on the spot. Appeals on height and chest are heard there the same day. Watch ssc.gov.in and delhipolice.gov.in.
Important Dates
| Event | Date |
|---|---|
| Notice on ssc.gov.in | 24 September 2025 |
| Applications | 24 September to 15 October 2025, 23:00 |
| Fee payment closes | 16 October 2025, 23:00 |
| Correction window, with charges | 23 to 25 October 2025 |
| Self slot selection | 4 December 2025 |
| CBE | December 2025 or January 2026, tentative |
| Tentative answer keys | 5 February 2026 |
| Revised vacancies | 25 February 2026 |
Age is reckoned on 1 July 2025; qualification, bonus certificates and category on the closing date. PE&MT and later dates are set by the Delhi Police and posted on both websites.
Admit Card
The CBE admit card comes from SSC on ssc.gov.in, after a city intimation. The PE&MT admit card is scheduled by the Delhi Police but downloaded through SSC's link, with a notice on delhipolice.gov.in.
Documents are checked at the PE&MT, so bring them there: category and relaxation certificates in the notice's formats, any hill-area or police-ward certificate, original NCC or RRU certificates (or no bonus), and your 10+2 or NTC mark sheets.
Result
SSC publishes tentative answer keys with the question paper and response sheet (5 February 2026 this cycle), then the CBE result, and finally the overall result, on ssc.gov.in with parallel notices on delhipolice.gov.in.
Vacancies fell after the notice:
| Male, as notified | Male, revised | Female, as notified | Female, revised | |
|---|---|---|---|---|
| Open | 285 | 226 | 163 | 132 |
| Ex-servicemen | 49 | 42 | none | none |
| Departmental | 36 | 29 | 19 | 14 |
| Total | 370 | 297 | 182 | 146 |
That's 109 fewer posts, from 552 to 443, which pushes the written cut-off up because the PE&MT shortlist is twenty times the vacancies.
Cut Off
SSC publishes category-wise cut-offs with each result on ssc.gov.in. None is published in advance.
The real bar is the merit range of twenty times the vacancies in each category, not the 40, 35 or 30 per cent floor. Cut-offs are on normalised marks plus bonus marks, so don't compare them directly with a raw score from the answer key. An NCC 'C' certificate is worth five marks here.
Preparation Tips
Win it in the written paper. Only the CBE ranks you; the later stages only knock you out.
Take General Science seriously. It's 25 marks and no other Delhi Police paper has it. Physics and chemistry only, with electronics, Ohm's law, fibre optics and communication topics.
Maths is 12th standard. Trigonometry, sequence and series, and permutation and combination are in. Reasoning includes banking-style topics: input-output, coded inequalities, data sufficiency. Generic Delhi Police material won't cover these; the Head Constable (Ministerial) paper has an English section and no General Science.
Learn the computer part once, use it twice. Part-E maps onto the later computer proficiency test. Typing 1,000 key depressions in 15 minutes is about 67 a minute, judged on accuracy.
Practise dictation and reading aloud in both languages. Over 50 per cent mistakes in either fails you. Work on your weaker language.
Train for the race early. 1600 m in 7 minutes for men, 800 m in 5 minutes for women up to 30, with no appeal.
Get bonus certificates ready. NCC 'C' is 5 per cent, 'B' 3 per cent and 'A' 2 per cent; a Rashtriya Raksha University degree or PG diploma counts 5 per cent with distinction, down to 2 per cent for a pass.
Sample Papers
SSC publishes the actual question paper with the tentative answer keys and your response sheet, for a limited window after the exam (5 February 2026 for this cycle). Download it while it's up. It has also published detailed marks for earlier cycles (the 2022 cycle on 1 February 2024).
Look under Previous Year Question Papers in the For Candidates menu on ssc.gov.in, and watch for the mock test notice before each exam.
