TSLPRB TGSRTC Supervisor Trainees TST/MST Preliminary 2026 Answer Key, PDF, Response Sheet and Objection Link

TSLPRB TGSRTC TST MST answer key 2026 overview

The preliminary answer keys for the TGSRTC Supervisor Trainee written examinations are now available on the official TGPRB website. The release covers both papers conducted on 29 March 2026: Traffic Supervisor Trainee in the forenoon session and Mechanical Supervisor Trainee in the afternoon session. Candidates should download the correct PDF for their post and compare answers according to their question paper booklet code.

This is a preliminary key, not the final key. If a candidate finds an issue in any answer, the board has provided an online objection facility in the secure candidate login area. The final key, result list, and further recruitment steps will depend on the board's review of valid objections.

Official dates and latest confirmed updates

No official date has yet been announced in the material checked for the final answer key or result declaration. Those should be treated as pending until the board publishes a separate notice.

Direct answer key PDF download links

The board has placed separate preliminary key PDFs on the official recruitment homepage for both papers:

• TST preliminary key PDF for Traffic Supervisor Trainee
• MST preliminary key PDF for Mechanical Supervisor Trainee

Each PDF contains booklet-code-wise answers for 200 questions. Candidates should make sure they are checking the correct post and the correct booklet code before calculating marks or preparing objections.

The official homepage currently shows these resources under the Supervisor Trainees Recruitment 2025 in TGSRTC section: Notification, Preliminary Key - TST, Preliminary Key - MST, and Apply for Objections on Preliminary Key.

How to download the TST or MST preliminary key

1. Visit the official TGPRB website.
2. Open the section for Supervisor Trainees Recruitment 2025 in TGSRTC.
3. Choose either Preliminary Key - TST or Preliminary Key - MST.
4. Open the PDF and match the answers with your question paper booklet code.
5. Save the PDF for score checking and objection preparation.

Do not compare your paper with the other post's key. TST and MST have separate answer key PDFs and separate question patterns in the original notification.

Objection link, fee and submission rules

The official press note states that objections must be submitted through the web template available in the respective candidate login area. The last time allowed is 5 PM on 7 April 2026. The board has fixed the fee at Rs. 500 for each objection, and the amount will be refunded if the objection is found correct.

• Each objection must be filed separately for each question.
• Supporting documents should be uploaded with the objection.
• Objections with insufficient information or irrelevant documents will not be considered.
• No manual representations will be entertained.

This means candidates should not bundle multiple questions into one submission. Every challenged question needs its own individual entry in the objection form.

Response sheet and candidate login access

The public homepage clearly shows the preliminary key PDFs and the objection portal link. The official press note confirms that the objection web template is available inside the candidate's login area. A separate public response-sheet PDF link is not shown on the homepage in the same way as the answer key PDFs.

So, for practical purposes, candidates should use the secure Supervisor Trainee portal to access candidate-side records, objection tools, and any response details made available after login. If a response sheet or question-wise response view is enabled for a candidate, it would be accessed there rather than through a public PDF link on the homepage.

Deleted questions and how marks will be handled

Both official key PDFs use the mark D* to indicate deleted questions. The board has already explained the scoring treatment for deleted questions in the notification and again in the press note. Marks for deleted questions will not be treated as normal right-or-wrong responses. Instead, they will be awarded proportionately based on the percentage of marks obtained by the candidate in the remaining undeleted questions.

This is important when you estimate your score using the preliminary key. Your rough score from directly matched answers may not perfectly equal the final normalized figure if deleted questions affect your booklet code. The final merit position will depend on the board's evaluated scoring after objection review.

Exam pattern and qualifying marks for TST and MST

The written examination for both posts was held in one paper of 3 hours for 200 marks with 200 objective questions on OMR. For TST, the paper included Supervisory Aptitude, Numerical Aptitude, Reasoning, General English and General Knowledge. For MST, the paper included Supervisory Aptitude, Engineering Aptitude, Reasoning, General English and General Knowledge.

The notification checked does not state a negative marking rule for wrong answers in this written examination section. Candidates should therefore rely on the official scheme exactly as published and wait for final score treatment where deleted questions apply.

Post wise vacancies and recruitment context

The answer key belongs to the Supervisor Trainees Recruitment 2025 in TGSRTC, which notified 198 total vacancies. Out of these, 84 are for Traffic Supervisor Trainee and 114 are for Mechanical Supervisor Trainee. The pay scale notified for both posts is Rs. 27,080 to Rs. 81,400.

This context matters because the answer key is part of an ongoing recruitment cycle, not a standalone exam event. The final merit list will feed into this same recruitment process for the notified TGSRTC posts.

Eligibility snapshot for the two posts

For candidates tracking the answer key and next recruitment stage, the original notification gives a clear post-wise qualification split. TST required a graduate degree as on 1 July 2025. MST required a Diploma in Automobile or Mechanical Engineering or an equivalent qualification in the same discipline as on 1 July 2025, and candidates with higher qualifications such as BE, BTech or AMIE in Automobile or Mechanical Engineering were also eligible.

The general age limit in the notification was 18 to 25 years as on 1 July 2025, along with notified relaxations. Men and women were eligible for both posts. The selection is based on written-exam merit, subject to verification, medical standards and other recruitment conditions in the notification.

What happens after the preliminary key

After the objection window closes, the board will review valid submissions and then issue a final answer key or further update. Once that stage is complete, the recruitment process can move toward score finalization, merit preparation, document verification and other downstream stages as applicable under the notification.

At this point, candidates should treat these as the practical next steps:

1. Download the correct TST or MST preliminary key.
2. Compare answers with the right booklet code.
3. Use the secure portal to submit question-wise objections before the deadline.
4. Keep login credentials, hall ticket details and supporting references ready.
5. Wait for the board's next official update on the final key and result-related steps.

No official final answer key date or result date was confirmed in the sources checked for this article, so any fixed timeline beyond the objection deadline should be treated as not yet announced.
