The answer key challenge window for the CSIR NET June 2026 examination is officially open from August 16. You can submit your challenges and complete the required fee payment online until 11:00 PM on August 18, 2026. You can review your responses and challenge any answers they believe to be incorrect. Raising an objection requires a non-refundable online payment within a specified, time-limited window. Subject experts will subsequently review all submitted challenges to determine if any adjustments to the key are necessary.

Following the expert evaluation, NTA will release the CSIR NET Final Answer Key. Candidate raw scores will then undergo a normalization process to compute subject-wise percentile scores. Only those candidates who meet or exceed the designated percentile cutoff thresholds will qualify for the Junior Research Fellowship (JRF) or Assistant Professorship (Lectureship).
