How to Download TNPSC CTS Answer Key 2026
Step 1: Open the TNPSC official website
Go to the official website of the Tamil Nadu Public Service Commission.
Look for the latest press release or examination-related update.
Step 2: Find the CTS answer-key notice
Look for a notice relating to the Combined Technical Services Examination (Non-Interview Posts) and tentative answer keys.
Read the examination dates mentioned in the notice before opening the PDF.
This is a useful habit because TNPSC conducts several examinations, and the names can look very similar.
Step 3: Open the answer-key link
Click the relevant answer-key link.
The Commission may provide separate PDFs or links according to subjects.
Step 4: Select your subject
Choose the subject corresponding to the paper you actually attempted.
Don’t download every PDF unless you genuinely need them.
Step 5: Save the PDF
Download the answer key to your phone or computer.
If you’re using Chrome on Android, the PDF can normally be saved through the download option. On a laptop, saving it into a separate folder for your TNPSC documents makes it easier to find later.
Step 6: Compare your responses
Open your response sheet or note down the answers you marked.
Then compare them question by question with the official key.
This is much more reliable than checking answers randomly.

TNPSC CTS Response Sheet 2026
The answer key and response sheet are two different things.
The answer key tells you what the Commission considers the correct answer.
The response sheet shows the response recorded for you.
You need both if you want to calculate your expected score accurately.
TNPSC has previously hosted CBT response portions and candidates’ answer sheets for Combined Technical Services examinations through its website. In some cases, candidates have been instructed to access these documents through their OTR details.
So, if you see a separate response-sheet notice, don’t ignore it just because you’ve already downloaded the answer key.
