Introduction

If you are preparing for Assam Police in 2026, one decision comes before any study plan: should you target the Sub-Inspector (SI) post or the Constable post? Both are conducted by the State Level Police Recruitment Board (SLPRB), Assam, both wear the same uniform, and both are stable Government of Assam jobs. But they are not the same recruitment, not the same eligibility, not the same exam pressure, and not the same starting position in the police hierarchy.

The Constable post is the entry-level rank of the force. It is open to candidates with a school-level qualification, the screening starts with a physical test, and it recruits in large numbers every cycle. The Sub-Inspector post is a supervisory officer rank. It needs a graduate degree, the written exam carries far more weight, and the vacancies are much smaller and more competitive.

Choosing between them is not about which post is "better" in the abstract. It is about which recruitment fits your education, your age, your physical readiness, your preparation runway and your long-term career goal. A 12th-pass aspirant who wants to join quickly and a final-year graduate who wants an officer-level start should not make the same choice.

This guide compares Assam Police SI and Constable on every factor that actually decides the outcome — eligibility, age, physical standards, PET/PST, written exam, syllabus, difficulty, salary, promotion, job role and work-life balance — and then gives a clear, practical recommendation for different candidate profiles. You can study the full post-wise data anytime on the Assam Police exam hub.

Data note: the figures below mirror SLPRB Assam's recent recruitment cycle, including the major 2025-26 notifications covering 1867+ vacancies. Exact numbers, dates and post-specific standards change with each notification, so always confirm the latest official SLPRB Assam advertisement before applying.

Eligibility Comparison

The single biggest filter between these two recruitments is eligibility. The Constable post is reachable for most school-pass candidates, while the SI post is closed to anyone without a degree.

Eligibility factorConstableSub-Inspector (SI)
NationalityIndian citizen as per SLPRB rulesIndian citizen as per SLPRB rules
EducationHSLC / Class 10 (AB) or Class 12 (UB)Graduate in any discipline (UB / AB)
DomicileAs per Assam / SLPRB notificationAs per Assam / SLPRB notification
Physical fitnessMandatory PST + PETMandatory PST + PET
Marital / characterAs per service rulesAs per service rules

What this means in practice: if you have only completed school, the Constable post is your realistic Assam Police entry in 2026. If you already hold or are about to complete a graduation degree, you can choose either — but the SI post is usually the smarter use of a degree because it gives a higher rank and higher grade pay for the same broad pay scale.

Age Limit Comparison

Age eligibility is close but not identical, and it interacts with relaxations.

PostAge limit (recent cycle)
Constable (UB / AB)18–25 years
Sub-Inspector (UB)20–26 years
Sub-Inspector (Communication)20–26 years

Age relaxation applies on top of these limits for reserved and special categories:

CategoryRelaxation
SC / ST5 years
OBC / MOBC3 years
Home Guards / VDP / Civil Defence3 years
FMMO / SPO10 years

Practical takeaway: a younger candidate (18–19) who has finished only school cannot wait years for a graduation degree if they are close to the Constable upper limit — for them, Constable is the time-sensitive option. A candidate in their early twenties who is finishing a degree fits comfortably inside the SI window and should aim higher. Always compute your age as on the cut-off date printed in the official SLPRB notification, then add any category relaxation.

Educational Qualification

This is where the two recruitments truly separate.

RecruitmentEducational qualification
Constable (Armed Branch / AB)HSLC / Class 10 pass
Constable (Unarmed Branch / UB)Class 12 pass
Sub-Inspector (UB)Graduate (any discipline)
Sub-Inspector (AB)Graduate (any discipline)
Sub-Inspector (Communication)BSc Electronics / IT / Computer Science, relevant diploma, MCA, or related BE/BTech

The Constable post is intentionally accessible — it is the foundation rank of the force, so a school qualification is enough. The SI post is an officer-track entry, so a degree is non-negotiable. The Communication SI sub-post adds a technical qualification requirement because the role involves wireless, electronics and signal work.

If you are still a student, this table effectively decides your timeline: school-pass aspirants prepare for Constable now; graduates (or final-year students who will graduate before the cut-off) prepare for SI.

Physical Standards Comparison

Standard Assam Police recruitment (which covers both Constable and SI in the general categories) uses the same physical standards. These are PST (Physical Standard Test) requirements verified before or alongside the physical efficiency events.

Candidate / CategoryHeightMale Chest
Male: General / OBC / MOBC / SC162.5 cm80 cm + 5 cm expansion
Male: ST(P) / ST(H)160 cmST(P): 80 cm + 5 cm; ST(H): 78 cm + 5 cm
Female: General / OBC / MOBC / SC154 cmNot applicable
Female: ST(P) / ST(H)152 cmNot applicable

Note that Commando Battalion recruitment uses tougher standards (for example 167 cm height and 85 cm + 5 cm chest for General male candidates). If you are looking specifically at Commando posts, the physical bar is higher than standard Constable or SI recruitment — check the Assam Police exam hub for the full Commando standards.

Key point: physical standards for standard Constable and SI recruitment are essentially the same. So PST is not a deciding factor between the two posts — what differs is when the physical test happens in the selection order and how much the written exam matters, which we cover next.

PET / PST Comparison

The Physical Standard Test (PST) checks height and chest. The Physical Efficiency Test (PET) checks running, jumping and strength events. Both posts require both tests, but their position in the process differs.

RecruitmentMale PETFemale PET
Constable3200 metre race; long jump; chin up (for AB)1600 metre race; long jump
Commando Battalion4800 metre race; long jump; chin up; 100 metre sprint2800 metre race; long jump

For Constable, the PET/PST is the first screening stage — you must clear the physical events before your written test is considered. This makes physical preparation non-negotiable from day one for Constable aspirants.

For Sub-Inspector, the written test comes first, and PST/PET is conducted for candidates who clear the written stage. SI candidates must still meet the same standard police physical standards and complete the notified physical events, but the order means a graduate with strong academics gets the first say. For the exact SI-specific running distances and event standards, always confirm the official SLPRB Assam SI notification, because post-wise PET events can be specified separately.

Bottom line: Constable is physical-first; SI is written-first. If your strength is fitness, the Constable order rewards you earlier. If your strength is academics, the SI order rewards you earlier.

Written Examination Comparison

Both posts have an objective written test, but its weight in the final result is very different.

Exam factorConstableSub-Inspector (SI)
Selection orderPET/PST → Written Test → Viva VoceWritten Test → PET/PST → Viva Voce
Role of written testQualifying-and-merit stage after physical screeningPrimary merit filter that shortlists for physical test
Level of paperSchool-level general studies and aptitudeGraduate-level general studies, reasoning and English
Competition at written stageLarge pool already filtered by PETSharp graduate-level cut-off
Viva voce / interactionYes, after writtenYes, after PET/PST

For Constable, the physical test screens the field first, and the written test then decides merit among physically qualified candidates. For SI, the written test is the gateway — a strong written score is what gets you to the PET stage at all, so SI demands deeper and more consistent academic preparation.

This is the practical reason SI is considered the tougher exam: the paper is pitched at graduate level, the cut-off is sharper because of fewer vacancies, and there is no physical-first filter to thin the crowd before the written test.

Syllabus Comparison

The good news for anyone deciding late: the core subjects overlap heavily. SLPRB Assam's written tests draw from a common pool of areas, with the SI paper expecting greater depth.

Subject areaConstable focusSI focus
General Knowledge & Current AffairsAssam, India and world basicsDeeper coverage, schemes, institutions
Assam-specific General StudiesHistory, geography, polity, cultureSame areas, more analytical depth
Reasoning & Mental AbilitySeries, coding-decoding, analogy, direction senseSame plus harder analytical reasoning
Quantitative AptitudeNumber system, percentage, ratio, averagesSame plus basic data interpretation
EnglishGrammar, vocabulary, comprehensionGrammar, comprehension, sentence usage at graduate level
Post-specific subjectsGenerally not requiredTechnical topics for SI Communication and allied posts

Common preparation areas across both:

  • General Knowledge & Current Affairs — current events of Assam, India and the world; government schemes, institutions and public administration.
  • Assam-specific General Studies — history, geography, polity, economy, culture and society of Assam; key Assam departments and security institutions.
  • Reasoning & Mental Ability — analogy, classification, series, coding-decoding, direction sense and basic analytical reasoning.
  • Quantitative Aptitude — number system, simplification, percentage, ratio, average, time and work, speed and distance and basic data interpretation.
  • English — grammar, vocabulary, comprehension and sentence usage.

Because the syllabus overlaps so much, a candidate who is unsure can start a common foundation now and specialise later. Build that base with CareerUdaya's Assam Police mock tests and revise with study materials.

Difficulty Level

Difficulty is not one number — it depends on which stage challenges you most.

Difficulty dimensionConstableSub-Inspector (SI)
Eligibility barrierLow (school qualification)High (graduate degree)
Physical demandHigh and screened firstHigh but after written
Written paper depthSchool-levelGraduate-level
Cut-off sharpnessModerate (more vacancies)High (fewer vacancies)
Overall competitionVery large applicant poolSmaller but stronger pool

In short: Constable is easier to become eligible for but demands you clear a physical filter up front, while SI is harder to qualify academically but rewards graduates who can top a sharper written cut-off. Neither is a soft option. Constable's large applicant pool means even a school-level paper needs disciplined accuracy and speed, and the PET is genuinely demanding. SI's smaller vacancy count means the merit line sits high.

Salary Comparison

Both posts sit in the same broad pay scale, but the grade pay differs, which is what separates Constable pay from SI pay in practice.

Post GroupPay ScaleGrade Pay
ConstableRs 14,000–70,000Rs 5,600
Sub-Inspector / Assistant Jailor / Communication / Station Officer / Squad CommanderRs 14,000–70,000Rs 8,700

The higher grade pay for SI (Rs 8,700 vs Rs 5,600) means a Sub-Inspector starts with a higher pay band and allowances than a Constable, even though both share the same pay scale range. On top of basic pay and grade pay, both posts receive applicable Assam government allowances (such as DA, HRA and other admissible benefits as per state rules). Actual in-hand pay depends on posting, allowances and deductions.

Takeaway: if salary is a major factor and you are eligible for both, SI is the stronger financial choice from day one because of the higher grade pay and officer-level allowances.

Promotion & Career Growth

Career growth in the Assam Police follows the standard state police hierarchy. The starting rank determines how far up the ladder you begin, and that is the biggest long-term difference between the two posts.

StageConstable entry pathSI entry path
Entry rankConstableSub-Inspector
Next ranksHead Constable → Assistant Sub-Inspector (ASI) → Sub-InspectorInspector
Mid-levelSub-Inspector → InspectorInspector → Deputy Superintendent of Police (DSP) track
Senior levelReached over a long service spanReached faster due to higher starting rank

A Constable can absolutely rise to Sub-Inspector and Inspector over a career, but the journey passes through Head Constable and ASI first, and promotions depend on service rules, seniority, departmental examinations and available vacancies. An SI starts at the rank a Constable may take many years to reach, and is positioned for the Inspector and DSP-track progression earlier.

Promotions in any police force depend on departmental rules, vacancies, seniority and qualifying examinations. Treat the ladders above as the typical direction of growth, not a guaranteed timeline.

Job Responsibilities

The day-to-day role differs because one is a field-execution rank and the other is a supervisory rank.

Assam Police Constable — typical duties:

  • Maintaining law and order on the ground.
  • Patrolling, guard duty, escort and crowd management.
  • Assisting investigations and field operations.
  • Executing instructions from senior officers.
  • Traffic, security and emergency-response support.

Assam Police Sub-Inspector — typical duties:

  • Supervising constables and station-level staff.
  • Registering and investigating cases (a core SI responsibility).
  • Maintaining records, reports and case diaries.
  • Leading field teams during operations.
  • Acting as a first-level officer in the police station hierarchy.

If you prefer hands-on field work and a fast entry, the Constable role suits you. If you want responsibility, investigation work and a leadership position from the start, the SI role is the better fit.

Work-Life Balance

Policing is a demanding service in any rank, and both posts involve shift duty, festival/election deployments and emergency call-outs. The difference is in the nature of the pressure.

  • Constable: more physically active field duty, longer hours on the ground, frequent patrol and guard postings. Pressure is operational and physical.
  • Sub-Inspector: more responsibility and accountability, investigation deadlines, supervision duties and answerability for station-level outcomes. Pressure is managerial and procedural.

Neither post offers a relaxed routine, especially early in service. Candidates who prefer structured field execution may find the Constable role more straightforward, while those who accept higher accountability in exchange for authority and pay will prefer SI.

Which Job is Better for 12th Pass Candidates?

For a 12th-pass (or Class 10-pass) candidate, the answer is usually straightforward: the Constable post is the right target right now.

  • You are eligible immediately — Constable (UB) needs Class 12 and Constable (AB) needs HSLC/Class 10.
  • You are not eligible for SI without a graduation degree, so SI cannot be your 2026 target unless you graduate first.
  • Constable recruits in large numbers, which improves your selection probability if your fitness and written accuracy are strong.

Smart strategy: if you are 12th-pass and young, prepare seriously for Constable now, and simultaneously pursue your graduation. Once you hold a degree, the SI door opens for a future cycle. Begin with the Assam Police Constable mock tests and build your physical training in parallel, because the Constable process screens fitness first.

Which Job is Better for Graduates?

For a graduate (or final-year student who will graduate before the cut-off date), the Sub-Inspector post is usually the better use of your qualification.

  • You get a higher starting rank than Constable.
  • You get higher grade pay (Rs 8,700 vs Rs 5,600) for the same pay scale.
  • You start on the officer track, positioned earlier for Inspector and DSP-track growth.

That said, graduates are also eligible for Constable, and some may still choose it — for example, if age is tight, if SI competition feels too steep this cycle, or if a quick entry matters more than rank. But if you can clear a graduate-level written cut-off, SI gives you more rank, more pay and more career runway for essentially the same uniform and service. Sharpen your written preparation with the Assam Police SI mock tests and review the official pattern through Assam Police SI previous year question papers.

Which Recruitment Has Better Promotion Opportunities?

Both posts can lead to senior ranks, but the SI recruitment gives a head start because of where you enter the hierarchy.

Career growth factorConstableSub-Inspector (SI)
Starting rankConstableSub-Inspector
Ranks to reach InspectorHead Constable → ASI → SI → InspectorSI → Inspector (one step)
Officer-track proximityReached over long servicePositioned early
Grade pay at entryRs 5,600Rs 8,700
Long-term ceilingHigh, but a longer climbHigh, with a faster start

A Constable's promotion path is real but longer, moving through Head Constable and ASI before reaching SI. An SI is already at the level a Constable works years to reach, which makes the route to Inspector and beyond shorter. If your single biggest priority is faster vertical growth and you are eligible, SI wins on promotion opportunity.

Preparation Strategy for Both Exams

Because the syllabus overlaps heavily, you can prepare a common base and then specialise. Here is a practical plan.

Step 1: Build a Common Foundation

Start with the shared subjects — General Knowledge, Assam-specific General Studies, Reasoning, Quantitative Aptitude and English. This base counts for both Constable and SI. Use:

Step 2: Train Physically From Day One

Whether you choose Constable or SI, you must clear the PST and PET. For Constable the physical test comes first, so it is urgent. Build running endurance (target the 3200 m male / 1600 m female Constable race standards), long jump and, for AB, chin-ups. Consistent daily training matters more than last-minute effort.

Step 3: Specialise by Post

Step 4: Use Previous Year Papers

Previous year papers reveal the real difficulty, weightage and Assam-focus of the exam. Work through the Assam Police SI previous year paper and read the detailed breakdown in Assam Police SI Previous Year Question Papers.

Step 5: Track Assam Current Affairs

Both papers test Assam-specific awareness. Keep a weekly note of Assam governance, schemes, security and public administration updates. Combine this with the post-wise data on the Assam Police exam hub so your preparation stays aligned with the official pattern. For related opportunities, also watch Assam Government Jobs.

Final Recommendation

There is no universal winner between Assam Police SI and Constable — there is only the right fit for your profile.

Choose Assam Police Constable if:

  • You have a school qualification (HSLC/Class 10 or Class 12) and want to join Assam Police in 2026 without waiting to graduate.
  • Your strength is physical fitness and you are comfortable clearing a PET-first process.
  • You want a higher selection probability from a larger vacancy pool and a faster entry into the force.

Choose Assam Police Sub-Inspector if:

  • You are a graduate (or will graduate before the cut-off).
  • You want an officer-level start, higher grade pay and faster promotion runway.
  • You can prepare for a sharper graduate-level written cut-off where the written test is the gateway.

For most aspirants the decision is settled by education and timing: school-pass candidates target Constable now and pursue graduation alongside; graduates use their degree to aim for SI. If you are eligible for both and can clear the SI written cut-off, SI is generally the stronger long-term bet on rank, pay and growth. If you need a faster, fitness-led entry, Constable is the practical choice.

Frequently Asked Questions

Is Assam Police SI better than Constable?

Neither is universally better — it depends on your eligibility and goals. SI is a higher supervisory rank with higher grade pay and faster promotion runway, but it needs a graduate degree and a sharper written cut-off. Constable needs only a school qualification, recruits in larger numbers and offers a faster entry. Graduates usually benefit more from SI; school-pass candidates target Constable.

What is the qualification difference between Assam Police SI and Constable?

Constable (AB) requires HSLC/Class 10, and Constable (UB) requires Class 12. Sub-Inspector (UB/AB) requires a graduate degree in any discipline. SI Communication additionally requires a relevant technical qualification such as BSc Electronics/IT/Computer Science, a relevant diploma, MCA or a related BE/BTech.

Which has a higher salary, Assam Police SI or Constable?

Both share the pay scale of Rs 14,000–70,000, but the grade pay differs: Constable has Rs 5,600 grade pay while SI has Rs 8,700 grade pay. The higher grade pay means an SI starts with higher pay and officer-level allowances than a Constable.

What is the age limit for Assam Police SI and Constable?

In the recent cycle, Constable (UB/AB) age limit is 18–25 years and Sub-Inspector (UB) is 20–26 years. Category relaxations apply on top — for example 5 years for SC/ST and 3 years for OBC/MOBC. Always check the cut-off date in the official SLPRB notification.

Is the physical test the same for SI and Constable?

Standard police recruitment uses the same physical standards for both — for example 162.5 cm height and 80 cm + 5 cm chest for general-category male candidates. The difference is the order: Constable clears PET/PST first and then the written test, while SI clears the written test first and then PET/PST. Commando Battalion posts have tougher physical standards.

Which exam is tougher, Assam Police SI or Constable?

SI is generally considered tougher because the written test is graduate-level, the vacancies are fewer and the merit cut-off is sharper. Constable is more accessible on eligibility but has a demanding physical-first screening and a very large applicant pool, so it is not a soft option either.

Can a 12th-pass candidate apply for Assam Police SI?

No. The Sub-Inspector post requires a graduate degree. A 12th-pass candidate can apply for the Constable (UB) post now and pursue graduation alongside to become eligible for SI in a future cycle.

Which recruitment has better promotion opportunities?

SI generally offers a faster promotion runway because it starts at a higher rank. A Constable can rise to SI and Inspector over a career, but the path moves through Head Constable and ASI first. An SI starts at the rank a Constable takes years to reach, positioning them earlier for Inspector and DSP-track growth. Promotions still depend on service rules, vacancies, seniority and departmental exams.

Should I prepare for SI and Constable together?

Yes, up to a point. The core subjects overlap heavily — General Knowledge, Assam General Studies, Reasoning, Quantitative Aptitude and English — so you can build a common foundation and physical base first, then specialise. Graduates can keep both options open and lean towards SI; school-pass candidates focus on Constable.

Where can I practise for Assam Police SI and Constable?

CareerUdaya offers free Assam Police mock tests for both posts. Use the Assam Police SI mock tests and Constable mock tests, work through the SI previous year paper, and study the full post-wise data on the Assam Police exam hub.

Does Assam Police SI or Constable have more vacancies?

Constable recruits in much larger numbers. In the recent major cycle, Constable vacancies were high (around 1052 UB and 663 AB), while Sub-Inspector vacancies were limited (48 UB and 4 Communication). Larger vacancies can improve Constable selection probability, while fewer SI seats make the SI cut-off more competitive.
