The Odisha Staff Selection Commission has released the OSSC CTSRE Answer Key 2026 for the Combined Technical Services Recruitment Examination (CTSRE)-2025 Preliminary Examination. The provisional answer key and response sheet were released on 30 October 2026 for the preliminary examination held on 26 October 2026. Candidates who appeared in the examination can check their tentative answer key and recorded responses through the official OSSC website and raise objections online within the prescribed window. Read the notification for eligibility, selection process, pay scale and all other information.
This is a provisional answer key, not a final key. After reviewing the objections, the Commission will publish the final answer key, and the result will be prepared on the basis of the final key. Candidates should therefore check the answers carefully and raise any valid objection before the deadline.
