BharatNotes Every IAS cadre has a Central Deputation Reserve (CDR) of up to 40% of Senior Duty Posts — officers earmarked to serve at the Union government. From the 2007 batch onwards, at least 2 years' service at Deputy Secretary/Director level under the Central Staffing Scheme is mandatory for empanelment as Joint Secretary at the Centre. States have been chronically under-supplying officers to the CDR, which is why the Centre proposed the controversial 2022 IAS (Cadre) Rules amendment.
What the CDR is, formally
Every state's IAS cadre, when notified under the IAS (Cadre) Rules 1954, includes a Central Deputation Reserve (CDR) — a fixed quota of officers earmarked for service at the Government of India. The CDR can be up to 40% of Senior Duty Posts in the cadre. It is not a list of named officers; it is a numerical entitlement of the Union government on that cadre.
For example, if a cadre has 100 Senior Duty Posts, up to 40 of its officers can be on central deputation at any time without depleting the cadre's substantive strength.
The Central Staffing Scheme (CSS)
The CSS is the umbrella mechanism through which DoPT recruits IAS, IPS, IFoS, IRS, IES, ISS and other Group A officers into Union ministries for fixed tenures, typically:
- Deputy Secretary: 4-7 years of service, tenure 5 years
- Director: 14+ years of service, tenure 5 years
- Joint Secretary: 17+ years of service, tenure 5 years
- Additional Secretary: 25+ years, no fixed tenure (extension-based)
- Secretary: 30+ years, top-of-pyramid posting
The CSS is administered by DoPT's Establishment Officer division, with the Civil Services Board (CSB) and Appointments Committee of the Cabinet (ACC) making final decisions.
The mandatory empanelment rule
The Appointments Committee of the Cabinet directs that for IAS officers of the 2007 batch onwards, at least 2 years' service at Deputy Secretary or Director level under the Central Staffing Scheme is mandatory for empanelment as Joint Secretary at the Centre. This rule was issued to:
- Force IAS officers to gain Union-government exposure during the formative mid-career years.
- Build a strong, professionally trained corps with both Centre and state experience.
- End the practice of IAS officers staying lifelong in their state cadres and then becoming Secretaries to GoI without ever having served below them in the Union hierarchy.
No central exposure at DS/Director level = no empanelment at JS level. Period.
How an officer goes on central deputation
- Offer list: The state government compiles an Offer List each year of officers it is willing to release for central deputation. In theory, every state must offer at least its CDR strength; in practice, most fall short.
- DoPT consultation: DoPT picks officers from the Offer List for specific positions.
- Officer consent: The officer must consent (cannot be force-deputed without consent under the existing rules — this is what the 2022 amendment proposed to change).
- State NOC: The state issues a No Objection Certificate.
- Centre's appointment: ACC approves; the officer is posted to a Ministry.
The chronic under-supply problem
As of 2021-22, only ~10% of the IAS cadre was on central deputation, against a target of ~40%. States — especially West Bengal, Tamil Nadu, Kerala, Telangana and Punjab — routinely refuse to release officers, citing their own vacancy pressures. The Centre has been left short of mid-level officers (Deputy Secretaries and Directors) for years.
The 2022 proposed amendment to the IAS (Cadre) Rules 1954 would have allowed DoPT to post IAS officers on central deputation bypassing state consent in case of disagreement. The proposal triggered strong objections from West Bengal, Tamil Nadu, Kerala, Maharashtra, Rajasthan, Chhattisgarh and Odisha, who saw it as federal overreach. The amendment was put on hold and has not been notified as of May 2026.
Why CDR matters for an aspirant
If you aspire to become a Secretary to GoI — the highest civilian post in the executive — your career roughly looks like:
- Years 1-7: State cadre (SDM, ADM, DM, Special Secretary in state)
- Years 7-12: First central deputation as Deputy Secretary/Director (mandatory under 2007-batch rule)
- Years 12-17: Return to state or stay at Centre as Director
- Years 17-25: Joint Secretary at Centre (5-year tenure)
- Years 25-30: Additional Secretary
- Years 30-35: Secretary, then retirement at 60
Missing the DS/Director CSS stint means no JS empanelment — your ceiling becomes Principal Secretary in your state, not Secretary to GoI.
What about cadres that 'don't release'?
If you are allotted to a cadre whose government routinely refuses to release officers — historically West Bengal, Tamil Nadu and a few others — you will face friction when seeking central deputation. Some officers from these cadres have ended up on central deputation only later in their careers, foreclosing the JS-level path. This is one of the silent factors aspirants do not consider when ranking cadres in DAF-II.
Mentor's note
The CDR is the most underappreciated piece of the cadre architecture. Most aspirants think 'cadre' means 'state I serve in.' In reality, it means 'state whose Offer List determines whether I ever get to serve at the Centre.' Politically pliant cadres release freely. Politically prickly cadres do not. If a Secretary-to-GoI track is your ambition, study your prospective cadre's CDR record over the last 10 years before ranking it.
