With major JKSSB exams approaching — FAA (Finance Accounts Assistant), JKPSI (Sub Inspector), JK Police Constable, and Health Department posts — every serious aspirant must understand how horizontal reservation works and how it directly affects the number of seats available in their category. This is not just theory — it determines how many actual OM or reserved category seats will be available for selection, and understanding it can help you accurately assess your chances.
Horizontal reservation cuts across vertical reservation. In JKSSB, it is applied for specific groups — Ex-Servicemen, Persons with Disabilities (PwD), and Women — as per the notification for each recruitment. JKSSB follows a specific method for applying horizontal reservation, and knowing which method they use is the most critical piece of information for any candidate calculating their selection probability.
JKSSB Horizontal Reservation 2026 Overview
| Particular | Details |
|---|---|
| Concept | Horizontal Reservation in JKSSB Recruitments |
| Applicable Exams | FAA, JKPSI, JK Constable, Health Department posts etc |
| Who Gets Horizontal Reservation | Ex-Servicemen, PwD, Women (as per notification) |
| Two Methods | Compartmentalized Method vs Overall/Top-to-Bottom Method |
| Method Used by JKSSB | Overall / Top-to-Bottom Method (Method 2) |
| Key Difference | Method 1 = fixed cuts per category; Method 2 = no fixed cuts |
What is Horizontal Reservation?
Reservations in government recruitment are of two types:
| Type | What It Means | Example |
|---|---|---|
| Vertical Reservation | Reservation for specific categories | Open Merit (OM), SC, ST, OBC, RBA, EWS, ALC |
| Horizontal Reservation | Reservation that cuts across ALL vertical categories | Ex-Servicemen, PwD, Women |
Horizontal reservation does not exist independently — it is carved out from within the vertical categories. This means the seats reserved for Ex-Servicemen, PwD, or Women are taken from the existing OM, SC, ST, or other category seats — not added on top of them.
Important Note: Horizontal reservation does not increase the total number of seats. It redistributes a portion of existing seats to specific groups (Ex-Servicemen, PwD, Women) across all vertical categories.
The Two Methods of Applying Horizontal Reservation
There are two recognised methods by which horizontal reservation can be applied:
- Compartmentalized Method
- Overall / Top-to-Bottom Method

Method 1 — Compartmentalized Method
How It Works
In this method, horizontal reservation is calculated separately within each vertical category.
Example — 100 Posts, 10% Horizontal Reservation
| Category | Total Seats | 10% Horizontal Reservation Seats |
|---|---|---|
| Open Merit (OM) | 50 | 5 seats (10% of 50) |
| Category X (Reserved) | 50 | 5 seats (10% of 50) |
| Total HR Seats | 10 seats |
What this means:
- Exactly 5 seats are cut from OM — regardless of merit scores
- Exactly 5 seats are cut from Category X — regardless of merit scores
- The cut from each category is fixed and predictable
Key Characteristic of Method 1
The number of seats cut from each vertical category is fixed and known in advance.
Method 2 — Overall / Top-to-Bottom Method (JKSSB’s Method)
How It Works
In this method, horizontal reservation is calculated from the total overall vacancies first — and then candidates are placed into their respective vertical categories based on merit.
Example — 100 Posts, 10% Horizontal Reservation
Step 1 — Calculate Total HR Seats
| Total Vacancies | HR Percentage | Total HR Seats |
|---|---|---|
| 100 | 10% | 10 seats |
Step 2 — Prepare the Overall Merit List and Filter Top HR Candidates
Once the merit list is prepared, the top 10 candidates who belong to a horizontal reservation group (Ex-Servicemen / PwD / Women) are identified — regardless of which vertical category they belong to.
Step 3 — Place Each HR Candidate into Their Vertical Category
Now the critical difference appears:
| Scenario | OM Seats Cut | Category X Seats Cut |
|---|---|---|
| All 10 HR candidates belong to OM | 10 | 0 |
| 7 HR candidates from OM, 3 from Category X | 7 | 3 |
| 5 HR candidates from each | 5 | 5 |
| All 10 HR candidates from Category X | 0 | 10 |
Key Characteristic of Method 2
The number of seats cut from each vertical category is NOT fixed. It wholly depends on which vertical category the shortlisted HR candidates belong to.
Important Note: Under Method 2, there is no way to know in advance exactly how many OM seats or reserved category seats will be reduced by horizontal reservation. This is determined only after the merit list is prepared and HR candidates are identified and placed into their categories.
JKSSB Uses Method 2 — Overall / Top-to-Bottom Method
JKSSB follows the Overall/Top-to-Bottom Method (Method 2) in all its recruitments.
This is the key fact every aspirant must know. When calculating expected seats in any JKSSB exam, remember:
- Horizontal reservation seats are first calculated from the total vacancy pool
- The top merit-scoring HR candidates are selected
- They are then placed into their respective vertical categories
- OM and reserved category seat reductions are not fixed — they depend entirely on where the HR candidates fall in the merit list
How This Applies to Upcoming JKSSB Exams
Now that you understand Method 2, apply this to the upcoming exams:
JKPSI — Sub Inspector (Exam: November 29, 2026)
When the JKPSI final merit list is prepared:
- Calculate total HR seats from overall JKPSI vacancies
- Identify top HR scoring candidates from the overall merit list
- Place them into their vertical categories (OM / RBA / ST / SC etc.)
- The reduction from OM seats will depend on how many top HR candidates belong to OM
FAA — Finance Accounts Assistant (Exam: November 15, 2026)
Same process applies. The FAA OM seat count after HR deduction cannot be predicted precisely in advance — it depends on the merit distribution of HR candidates.
JK Police Constable (Executive) — December 13, 2026
Similarly, Constable OM and reserved category seats will only be finalized after HR candidates are identified from the top of the overall merit list.
Health Department Posts (September–October 2026)
The same Method 2 applies across all Health Department posts advertised under JKSSB Notification 07 of 2025.
JKSSB Horizontal Reservation FAA JKP SI Constable
| Exam | Total OM Seats | Net OM Seats remaining (approx.) |
| FAA | 240 posts | 200 (10% HR) |
| JKPSI | 267 posts | 165 (21% HR) |
| Constable Executive | 728 posts | 250 (40% HR) |
Important Note: For any JKSSB exam, when you see “X% horizontal reservation,” do not assume a fixed number of OM seats will be cut. Under Method 2, the actual OM seat reduction depends on merit — it could be more or less than a straightforward percentage calculation.
Side-by-Side Comparison — Method 1 vs Method 2
| Feature | Method 1 (Compartmentalized) | Method 2 (Overall / Top-to-Bottom) |
|---|---|---|
| How HR is calculated | Per vertical category separately | From total overall vacancies |
| Are cuts per category fixed? | Yes — fixed and predictable | No — depends on merit distribution |
| Which category bears the cut? | Each category proportionally | Only categories where HR candidates rank |
| Predictability | High — candidates can calculate in advance | Low — depends on final merit list |
| Used by JKSSB? | ❌ No | ✅ Yes |
Practical Takeaway for Candidates
Understanding this concept helps you:
- Avoid overestimating OM seats — if many HR candidates score high in the merit list and belong to OM, OM effective seats could reduce significantly
- Avoid underestimating your chances — if HR candidates are concentrated in reserved categories, OM seats may not reduce much
- Focus on your score — under Method 2, merit is the primary driver. A higher score protects you from the variability of HR seat adjustments
- Read each notification carefully — the percentage of horizontal reservation (for Ex-Servicemen, PwD, Women) varies by post and notification
Conclusion
JKSSB follows the Overall/Top-to-Bottom Method (Method 2) for horizontal reservation in all its recruitments — including the upcoming FAA, JKPSI, Constable, and Health Department exams. Under this method, total horizontal reservation seats are calculated from overall vacancies, top HR candidates are identified from the merit list, and they are placed into their vertical categories — meaning the seat reduction per category is not fixed and varies based on merit distribution. The key takeaway for every aspirant: focus on maximising your score, because under Method 2, your rank in the merit list determines everything.

Frequently Asked Questions (FAQs)
Q1. What method does JKSSB use for horizontal reservation?
JKSSB uses the Overall / Top-to-Bottom Method (Method 2) for horizontal reservation in all its recruitments. Under this method, total HR seats are first calculated from overall vacancies, top-scoring HR candidates are identified from the merit list, and then placed into their vertical categories — so the seat cut per category is not fixed.
Q2. What is the difference between compartmentalized and overall method for horizontal reservation?
In the Compartmentalized Method, horizontal reservation is calculated separately within each vertical category — giving fixed seat cuts per category. In the Overall Method (used by JKSSB), HR seats are calculated from total vacancies and distributed based on where the top HR candidates rank — making the per-category cut variable and unpredictable in advance.
Q3. How does horizontal reservation affect JKPSI OM seats?
Under JKSSB’s Overall Method, the reduction in JKPSI OM seats due to horizontal reservation depends on how many of the top-ranking HR candidates (Ex-Servicemen, PwD, Women) belong to the Open Merit category. If most HR candidates rank in OM, more OM seats are cut. If they rank in reserved categories, fewer OM seats are affected.
Q4. Who gets horizontal reservation in JKSSB recruitments?
Horizontal reservation in JKSSB is provided to specific groups as per each notification — typically Ex-Servicemen (ESM), Persons with Disabilities (PwD), and Women. The percentage varies by post. These groups receive reservation that cuts across all vertical categories (OM, SC, ST, OBC, RBA, EWS, ALC).
Q5. Can I calculate exact OM seats in JKSSB exams after horizontal reservation?
No — not with complete precision. Under JKSSB’s Overall/Top-to-Bottom Method, the exact OM seat reduction depends on the final merit distribution of HR candidates. You can estimate a range, but the final number is only confirmed after the merit list is prepared and HR candidates are placed into their vertical categories.
