For decades, the Civil Services Examination quietly allowed officers already in service to attempt the exam again in search of better ranks or preferred services. With the Civil Services Examination (CSE) 2026 notification, that flexibility has been sharply curtailed.
Under the new rules, officers serving in the Indian Administrative Service (IAS) and the Indian Foreign Service (IFS) are completely barred from appearing in CSE 2026 unless they resign from service. The restriction applies at every stage of the examination cycle.
If a candidate is appointed to IAS or IFS after clearing the Preliminary Examination but before the Mains, they will not be permitted to write the Mains. If the appointment takes place after the Mains begin but before the final result, the candidate will not be considered for service allocation under CSE 2026. In effect, serving IAS and IFS officers can reappear only after resigning.
The notification also clarifies rules for the Indian Police Service (IPS). Candidates already selected or appointed to IPS through an earlier examination cannot seek allocation to IPS again through CSE 2026. However, they may still appear for the examination and compete for other civil services, subject to eligibility.
UPSC has also introduced a one-time improvement option. Candidates allotted IPS or Central Services Group ‘A’ through CSE 2026 will be allowed to reappear in CSE 2027 by formally seeking exemption from joining training for their 2026 allotment. This exemption is permitted only once.
If selected again in CSE 2027, the candidate must choose between the 2026 and 2027 service allotments, with the unchosen option cancelled. If the candidate fails to secure selection in 2027, they may join the 2026 service. Failure to join training in either scenario will result in cancellation of both allotments.
A special window has also been provided for candidates allotted services through CSE 2025 or earlier. Such candidates may appear once in either CSE 2026 or CSE 2027 without resigning. From CSE 2028 onwards, resignation will be mandatory for any further attempt.
By closing long-standing loopholes, UPSC has introduced clearer boundaries around repeat attempts. The revised framework demands sharper decision-making from candidates already in service, signalling a decisive shift toward stability and finality in civil service allocations.
