Downloading the TNPSC CTS Answer Key 2026 is straightforward. Follow these exact steps to access the correct subject-wise PDF for your post from the official TNPSC portal.

Advertisement4
  1. Visit the official TNPSC website — Open your browser and go to tnpsc.gov.in. This is the only authentic source; do not use third-party websites that may show incorrect or outdated answer keys.
  2. Navigate to the Answer Keys section — On the homepage, look for the “Answer Keys” link in the main navigation menu or in the latest notifications/announcements section.
  3. Select the correct examination — Click on “Combined Technical Services Examination (Non-Interview Posts)” under Notification No. 04/2026. Do not accidentally click on the Interview Posts answer key, which is from a different notification.
  4. Choose your subject — The answer keys are published subject-wise with corresponding subject codes (e.g., Agriculture – Code 492, General Studies – Code 503). Select the PDF for the paper you appeared in.
  5. Download and save the PDF — Click the download link, save the PDF to your device, and take a printout for offline reference.

💡 Pro Tip
Always download the answer key directly from tnpsc.gov.in and verify the subject code matches your exam paper before comparing answers. TNPSC publishes separate PDFs for each subject; using the wrong subject’s answer key will give you completely incorrect score estimates. If the PDF link is temporarily unavailable, try accessing the TNPSC website during off-peak hours (early morning or late night).

How to Raise an Objection Against the TNPSC CTS Answer Key 2026

If you believe any answer in the TNPSC CTS Answer Key 2026 is incorrect, TNPSC provides an online Answer Key Challenge facility.

Here is the complete step-by-step process to raise your objection successfully.

  1. Log in to the TNPSC candidate portal — Go to tnpscexams.in and sign in using your TNPSC One-Time Registration (OTR) credentials (registration number and password).

  4. State your objection clearly — Select the answer you believe to be correct and provide a clear written justification in the provided text field. Be factual and reference a credible source.
  5. Upload supporting documentary evidence — This is mandatory. Accepted documents include scanned pages from standard textbooks, government publications, NCERT books, or peer-reviewed journal articles. Attach a clear, legible scan in PDF or image format.
  6. Pay the objection fee (if applicable) — Check whether TNPSC charges a fee per objection at the time of submission. Fees are typically refunded if the objection is upheld.

  6. Calculate your total — (Correct answers × marks per question) – (Wrong answers × deduction per question) = Estimated Score.

Provisional vs Final Answer Key — What Is the Difference?

Many candidates confuse the provisional (tentative) answer key with the final answer key. Understanding the difference helps you act correctly and avoid relying on scores that may change.

🔵 Expert Verdict
Always base your preparation and rank estimate on the final answer key, not the provisional one. In the TNPSC Group 1 2025 exam cycle, 6 answers were modified after objection review, shifting the cut-off by 9 marks. If you have strong evidence for even one question, file your objection — a single mark can make a significant difference in the merit rank for 508 posts contested by thousands of candidates.

Advantages and Disadvantages of the TNPSC CTS Objection Process

The TNPSC answer key objection facility is a transparent mechanism that benefits genuine candidates. However, it also has limitations that aspirants should be aware of.

Advantages (Pros) of Raising an Objection

  • ✅ Improves score fairness: A single corrected answer can shift multiple candidates’ ranks and improve overall merit list accuracy
  • ✅ Expert-reviewed process: All objections are verified by a panel of subject matter experts, not just junior staff
  • ✅ Online and accessible: The entire process is conducted digitally, saving candidates time and travel costs

Disadvantages (Cons) of the Objection Process

  • ❌ Hard deadline: The 14 October 2026 at 5:45 PM cutoff is strictly enforced — even technical glitches on the candidate’s end are not accepted as valid excuses
  • ❌ Documentary evidence mandatory: Objections without supporting documents are automatically rejected, making casual or unverified objections pointless
  • ❌ No individual response: TNPSC does not communicate the outcome of each objection individually; changes are reflected only in the published final key
