In short

  • There are three entry levels: Constable (after Class 12), Sub-Inspector (SI) (after graduation), and IPS officer (through the UPSC Civil Services Exam).
  • Constable and SI are recruited by state police boards (and SSC CPO for SI in Delhi Police/CAPF); the IPS is recruited only through UPSC.
  • Every route has a written test, a physical test (height, chest, running) and a medical and background check.
  • You can also rise internally — a constable or SI can be promoted up the ranks over a career.

A police career has more than one door. You can start as a constable straight after Class 12, enter as a sub-inspector after a degree, or aim for the officer cadre through the civil-services exam. This guide maps all three routes — the eligibility, the physical standards and the exams — so you can pick the one that fits where you are now.

The three ways to join

Entry Minimum education Recruited by Becomes
Constable Class 12 (some 10th) State police board Constable → Head Constable → ASI
Sub-Inspector (SI) Graduation State SI exam / SSC CPO SI → Inspector → DSP (by promotion)
IPS officer Graduation UPSC Civil Services ASP → SP → DIG → IG and above

The same uniform, three very different starting points. Which one you target depends mainly on your current qualification and how high you want to start.

Route 1 — Constable (after Class 12)

The most accessible entry. State police forces recruit constables through a written test plus a physical efficiency/standard test (PET/PST) — height, chest and a timed run — and a medical check. The central armed forces fill constable (GD) posts through the SSC GD exam; the physical standards for that are laid out in the physical standards for the central constable exam. From constable you can be promoted over the years to Head Constable and Assistant Sub-Inspector.

Route 2 — Sub-Inspector (after graduation)

If you are a graduate, you can enter one rung higher as a Sub-Inspector. SI is recruited two ways:

  • State SI exam — each state police board runs its own SI recruitment (written test + physical + medical). A recent example is the state sub-inspector result.
  • SSC CPO — the Staff Selection Commission recruits SIs for Delhi Police and the central armed police forces (CAPFs) through the CPO exam.

From SI you can be promoted to Inspector and, in time, to Deputy Superintendent of Police (DSP).

Route 3 — IPS officer (the top route)

The Indian Police Service (IPS) is the officer cadre, and it has a single door: the UPSC Civil Services Examination, the same exam that recruits the IAS. Clearing it and getting allotted to the IPS makes you an Assistant Superintendent of Police, rising to SP, DIG, IG and above. How the IPS compares with the IAS and IFS is covered in the IPS route runs through the civil-services exam. You can also reach the officer ranks without UPSC — by clearing a State PCS, which recruits Deputy Superintendents of Police (DSP) directly.

Physical standards — the common gate

Whatever the route, you must clear a physical standard test: a minimum height and chest (typically around 165–170 cm for men and 150–157 cm for women, varying by state and post) and a timed run, plus a medical examination. There are relaxations for ST candidates and hill communities. Because the exact numbers differ by state and post, always read your recruitment's notification, and start your running and fitness practice early — many candidates clear the written stage but stumble at the physical.

Police Officer: हिंदी सारांश

पुलिस में भर्ती के तीन मुख्य रास्ते हैं — कांस्टेबल (12वीं के बाद, राज्य पुलिस भर्ती), सब-इंस्पेक्टर/SI (स्नातक के बाद; राज्य SI परीक्षा या SSC CPO), तथा IPS अधिकारी (UPSC सिविल सेवा परीक्षा द्वारा)। हर रास्ते में लिखित परीक्षा, शारीरिक परीक्षण (ऊंचाई, सीना, दौड़) तथा चिकित्सा व पृष्ठभूमि जांच होती है। कांस्टेबल व SI की भर्ती राज्य पुलिस बोर्ड (तथा दिल्ली पुलिस/CAPF हेतु SI के लिए SSC CPO) करते हैं, जबकि IPS केवल UPSC से होता है। State PCS के माध्यम से सीधे DSP भी बना जा सकता है। ऊंचाई/सीना/दौड़ के मानक राज्य व पद अनुसार भिन्न होते हैं (ST व पहाड़ी वर्गों को छूट), इसलिए अधिसूचना अवश्य देखें।

FAQs

How can I become a police officer in India? / Police officer kaise bane?
There are three routes: become a constable after Class 12 through state recruitment, a sub-inspector after graduation through a state SI exam or SSC CPO, or an IPS officer through the UPSC Civil Services Exam. Each involves a written test, a physical test and a medical check.
What is the difference between a constable, SI and IPS officer?
A constable is the entry rank (Class 12 eligibility), a sub-inspector is a graduate-level supervisory rank, and an IPS officer is the senior officer cadre recruited only through UPSC. You can also rise from constable or SI to higher ranks by internal promotion over a career.
How can I become an IPS officer? / IPS officer kaise bane?
The only route to the IPS is the UPSC Civil Services Examination — Prelims, Mains and Interview — after which you must be allotted the Indian Police Service. You need a Bachelor's degree and to be within the UPSC age band (generally 21–32 for the General category, with relaxations).
What is the height requirement for police? / Police ke liye height kitni chahiye?
It varies by state and post, but is typically around 165–170 cm for men and 150–157 cm for women, along with a chest measurement (for men) and a timed run. ST candidates and certain hill communities get relaxations. Always check the exact standard in your recruitment's notification.
Can I become a DSP without UPSC?
Yes. A State PCS exam recruits Deputy Superintendents of Police (DSP) directly, so you can reach an officer rank without clearing UPSC. You can also be promoted to DSP over time from the sub-inspector and inspector ranks.
Which exam is for sub-inspector?
Two main ones: each state police board's SI exam for that state's police, and SSC CPO for Sub-Inspector posts in Delhi Police and the central armed police forces. Both require a graduation degree and clearing a written test plus physical and medical standards.

His desk owns every page tagged to the Union Public Service Commission (UPSC Civil Services, CAPF AC, IES/ISS, IFS, Geo-Scientist), the Staff Selection Commission (SSC CGL, CHSL, GD Constable, MTS, JE, Stenographer, Selection Post), and the National Testing Agency notifications that route through DoPT. He holds an MBA, and uses that training to build the structured selection-process explainers and competitor analyses his beat is known for — particularly the SSC CGL Tier-1 vs Tier-2 weightage breakdowns and the UPSC Prelims category-wise cut-off tables. Vishal has been writing about Indian central-government recruitment since 2019, first as a freelance contributor to coaching-institute blogs and then as a full-time editor. His sourcing rule for this desk is simple: a notification page only goes live after the official PDF on upsc.gov.in or ssc.gov.in has been opened, the vacancy and date numbers cross-checked against the actual gazette, and the source-link verified to still load. If any of those three fail, the page sits in draft until the source is clean. "I would rather publish a page two hours later than ship a vacancy number that's off by a thousand. Aspirants make life decisions on these numbers. We owe them the exact figure on the official PDF, not the round number a news site copied from somewhere else." — Vishal
