Reservation in Government Jobs: Categories, Percentages, and How It Actually Works

Clear explanation of SC, ST, OBC, EWS, PwD, and Ex-servicemen reservation in govt recruitment — constitutional basis, roster system, creamy layer, and state variations.

Reservation in government jobs is one of the most discussed — and most misunderstood — topics in public employment. People confuse vertical and horizontal reservations, don't understand the roster system, and often have incorrect assumptions about creamy layer rules.

Here's a clear explanation of how reservation actually functions in central government recruitment.

Constitutional Basis

Reservation in government employment has two main constitutional provisions:

Article 16(4): Allows the state to make provisions for reservation in appointments or posts in favour of any backward class of citizens which, in the state's opinion, is not adequately represented in services.
Article 16(4A): Extended reservation to promotion in services for SC/ST communities.
Article 15(4) and 15(5): Allow special provisions for advancement of socially and educationally backward classes or SC/ST.
103rd Constitutional Amendment (2019): Added Article 15(6) and 16(6) to enable up to 10% reservation for Economically Weaker Sections (EWS) from the unreserved category.

Category-Wise Reservation Percentages (Central Government)

Category	Reservation Percentage
Scheduled Caste (SC)	15%
Scheduled Tribe (ST)	7.5%
Other Backward Classes — Non-Creamy Layer (OBC-NCL)	27%
Economically Weaker Sections (EWS)	10%
Total	59.5%
Unreserved (General/UR)	40.5%

So in 100 vacancies at the central level: 15 go to SC, 7 to ST (rounded), 27 to OBC-NCL, 10 to EWS, and 40-41 to general candidates.

Vertical vs Horizontal Reservation

This distinction trips up many aspirants.

Vertical reservation is the category-based allocation (SC/ST/OBC/EWS). These are separate columns of vacancies and each column has its own merit list. Horizontal reservation cuts across categories and applies to specific groups within all vertical categories:

Persons with Benchmark Disabilities (PwBD): 4% of total vacancies (1% each for 4 subcategories — blindness/low vision, deaf/hard of hearing, locomotor disability, others)
Ex-Servicemen: 10% of Group C posts, 14.5% of Group D posts (varies by department and post)
Women: 33% in many state government recruitments; central government has varying percentages by department and post

How horizontal reservation works: A PwBD candidate's vacancy is filled from within each vertical category. So if there are 4 SC vacancies and 1 SC-PwBD vacancy, the PwBD candidate is selected from the SC pool — not in addition to it.

What is the Creamy Layer?

The creamy layer concept applies only to OBC candidates for central government jobs. The idea: if an OBC family has reached a certain economic level, they no longer need the reservation meant for backward communities. These families constitute the "creamy layer" and are excluded from OBC reservation benefits.

Current central government creamy layer income ceiling: ₹8 lakh per annum (family income, revised in 2017 from ₹6 lakh)

Creamy layer also includes:

Children of constitutional post holders (President, Vice President, etc.)

Children of IAS/IPS/IFS officers (Group A) and their state equivalents

Children of armed forces officers above Colonel rank

Children of PSU employees above a certain grade

If you are OBC but fall in the creamy layer:

You CANNOT claim OBC reservation (must compete in general/UR category)

You CANNOT claim OBC age relaxation

You CAN still claim OBC reservation in some state government exams if the state has its own creamy layer definition

SC and ST categories have no creamy layer concept at the central level. A wealthy SC/ST family's children still retain reservation benefits. (The Supreme Court has periodically revisited this, but as of now, no creamy layer applies to SC/ST for reservation purposes.)

How the Roster System Works

The roster is the mechanism that ensures reserved vacancies are distributed fairly across consecutive recruitment cycles. Without a roster, an organization could theoretically hire all reserved-category posts in one batch and then hire only general candidates for years.

Point roster: A register maintained by each department showing which vacancy number (1, 2, 3...) is reserved for which category. When a new vacancy arises, you check which point in the roster it falls on — that determines the category. Example for 100-post roster (simplified):

Post 1: UR
Post 2: UR
Post 3: OBC
Post 4: UR
Post 5: SC
Post 6: UR
Post 7: OBC
Post 8: UR
Post 9: UR
Post 10: ST
...and so on

The pattern continues such that over a full cycle of posts, the percentages approximately match statutory requirements (15% SC, 7.5% ST, 27% OBC, 10% EWS, rest UR).

EWS Reservation: Who Qualifies?

The 10% EWS reservation (added in 2019) is for unreserved general category candidates whose family income is below ₹8 lakh per annum AND who do not own:

Agricultural land of 5 acres or more

Residential flat of 1,000 sq ft or more

Residential plot of 100 sq yard or more in notified municipalities

Residential plot of 200 sq yard or more in non-notified municipal areas

Important: SC, ST, and OBC-NCL candidates cannot claim EWS — it is exclusively for those not covered under other reservation categories.

EWS certificate is issued by a competent authority (Tehsildar or equivalent) and is valid for the financial year mentioned. You need a fresh certificate for each year's application.

UPSC Supreme Court Rulings You Should Know

Indra Sawhney case (1992): The Supreme Court upheld OBC reservation and capped total reservation at 50%. EWS reservation technically pushes this above 50%, which is why it was legally challenged. Jarnail Singh case (2018): Reaffirmed that creamy layer must be applied to SC/ST in promotions (though not in initial appointments). Maratha Reservation case (2021): Supreme Court struck down Maharashtra's Maratha reservation that exceeded the 50% cap, reaffirming the ceiling. EWS Constitutional validity (2022): A 5-judge bench upheld the 10% EWS reservation as constitutionally valid in a 3:2 majority verdict. The 103rd Amendment was not violative of the basic structure of the Constitution.

State-Wise Reservation Variations

State governments can add to — but not remove from — central reservation mandates for their own recruitment.

State	Additional/Variation
Tamil Nadu	Total reservation: 69% (exceeds 50% cap, protected by 9th Schedule)
Maharashtra	Maratha reservation (OBC sub-quota) — struck down, currently under review
Rajasthan	Additional 5% for Gujjars (MBC category) within OBC
Bihar	BC (Backward Class) and EBC (Extremely Backward Class) sub-categories within OBC
Kerala	Christian converts from SC continue to get SC status in Kerala (unique state provision)
Karnataka	Additional OBC sub-categories; Lingayat/Vokkaliga inclusion debates

State reservations for state government jobs do not apply to central government jobs — always check which government the post belongs to.

Practical Tips for Reservation Documentation

SC/ST Certificate: Issued by district/tehsildar authority. Must specify the scheduled caste/tribe name. No expiry, but must be issued from the home state domicile.

OBC-NCL Certificate: Has a validity period (usually issued for a specific financial year). Always use the most recent certificate. Must be in the central government format — state OBC certificates may not be accepted for central exams.

EWS Certificate: Valid only for the financial year. Must be on the format specified in DOPT/government order.

PwBD Certificate: Issued by a specified medical board. Must mention the percentage of disability (minimum 40% required for reservation) and the type of disability.

FAQ

Q: If I belong to OBC but competed and got selected in the UR category, does my OBC vacancy remain unfilled? Yes — the OBC vacancy is then filled by the next OBC candidate on the merit list. Your selection as an OBC in the UR category benefits the UR quota as well, in a sense — the OBC vacancy goes to the next person. Q: My OBC certificate is from my state. Can I use it for SSC or UPSC exams? For central government exams, the OBC list is the Central List of OBCs (notified by the Ministry of Social Justice). If your caste is on the central list AND you have an NCL certificate in the correct central format, you're eligible. Being on the state OBC list alone is not sufficient. Q: Can PwBD candidates apply in the UR category instead? Yes — a PwBD candidate can apply as a general/UR candidate and compete without using the disability reservation if they prefer. Their reservation benefit is available but not mandatory to use. Q: Does domicile affect reservation claims in central government exams? No — SC/ST/OBC reservation in central government recruitment is based on your caste/community, not domicile. However, state government exams may require both category certificate AND state domicile proof.
