CSIR NET December 2025 Answer Key is expected to be released soon by the National Testing Agency (NTA). The provisional answer key will be issued for the examination conducted on 18 December 2025 for candidates who appeared across various subject papers. Once released, the answer key will be made available on the official CSIR NET website. Candidates will be able to download the provisional answer key and their recorded responses using their login credentials. The release of the answer key will mark the next stage of the post-examination process for the December session.
CSIR NET December 2025 Answer Key Release and Subject-wise Availability
The National Testing Agency releases the CSIR NET provisional answer key separately for each subject. For the December 2025 session, answer keys will be issued for Chemical Sciences, Earth Sciences, Life Sciences, Mathematical Sciences, and Physical Sciences. Before accessing the answer key, candidates should note that it is provisional in nature. This means the responses displayed are subject to verification and may be revised after considering challenges raised by candidates. Along with the provisional answer key, NTA will also display the response sheet, enabling candidates to cross-check their recorded answers and calculate an estimated score.
CSIR NET 2025 Answer Key Objection Window and Review Process
After the release of the provisional answer key, NTA will open the answer key objection window for a limited duration. During this period, candidates who find discrepancies in any answer will be allowed to submit objections. Candidates must support their objections with valid academic references, as objections without justification are unlikely to be accepted. Each challenge will be reviewed by subject experts appointed by NTA. Once the objection process is completed, the authority will release the final CSIR NET answer key. The CSIR NET 2025 result will be prepared based on the final answer key, and no further challenges will be entertained after its publication.
