SC, ST or OBC candidates applying against an unreserved post get no age relaxation — though SC and ST candidates keep their fee exemption. Because no post here is reserved for SC, SC candidates get no age relaxation at all in this advertisement, only the fee exemption. PwBD age relaxation applies only if the post is identified as suitable for your category of disability, and only against a certificate showing 40% or more disability.
EWS candidates must have a family gross annual income below ₹8 lakh, and are excluded regardless of income if the family owns 5 acres or more of agricultural land, a flat of 1,000 sq ft or more, or a residential plot of 100 sq yd (notified municipality) or 200 sq yd (elsewhere) or more. Your Income and Asset Certificate must be valid as on 21 September 2026 — one issued later, or for a later financial year, will not be accepted.
What is the Salary for CSIR NAL MTS 2026?
The post carries Pay Level-01 in the 7th CPC pay matrix, ₹18,000 – ₹56,900. That figure is printed in the advertisement, so you can rely on it.
Your take-home is considerably higher because CSIR-NAL adds the standard central government allowances — Dearness Allowance, House Rent Allowance (not paid if Council accommodation is allotted) and Transport Allowance. You also get National Pension System coverage, medical reimbursement, Leave Travel Concession and Children Education Allowance. One condition worth knowing: during the two-year probation you are not permitted to apply for appointment elsewhere or even within CSIR-NAL, and any applications already sent to other organisations must be disclosed immediately after joining.
What is the Selection Process for CSIR NAL MTS Recruitment 2026?
Completely merit-based — the merit list comes purely from the written exam, and the notification prescribes no interview stage.
| Stage | What happens |
|---|---|
| 1. Screening of applications | Based on the documents and information you submit |
| 2. OMR written examination | Single paper; the merit list comes purely from this |
| 3. Certificate verification | Missing the essential qualification cancels selection |
Written Exam Pattern
The paper is at Class X standard — 150 questions in 2 hours, 3 marks per correct answer and 1 mark deducted for every wrong answer. So guess carefully.
| Subject | Questions | Marks |
|---|---|---|
| General Intelligence | 25 | 75 |
| Quantitative Aptitude | 25 | 75 |
| General Awareness | 50 | 150 |
| English Language | 50 | 150 |
Questions are set in English, Hindi and Kannada except the English Language section. The exam is held in Bengaluru only, no centre or date change is allowed, and no travel allowance is paid. Ties are broken by fewer negative marks, then older age, then who acquired the qualification earlier. Practise with the exam syllabus material on GovtJobsAlert.in.
How to Apply for CSIR NAL MTS Recruitment 2026?
This is an offline application only — the website hosts the advertisement and form, not a submission portal.
| Step | Action |
|---|---|
| 1 | Download the prescribed form from the official website (link below) |
| 2 | Fill it neatly typed on A4 paper — handwritten forms are rejected |
| 3 | Affix a self-attested passport photo and sign the form |
| 4 | Prepare a ₹500 Demand Draft unless you are fee-exempt |
| 5 | Attach self-attested copies of all required documents |
| 6 | Superscribe the envelope “Application for the Post of MTS, Advt. No. 11/2026” |
| 7 | Send by Speed Post or Courier only, in a single envelope |
Post it to: The Director, CSIR-National Aerospace Laboratories (CSIR-NAL), Post Bag No. 1779, HAL Airport Road, Kodihalli, Bengaluru – 560017, Karnataka. Your envelope must contain the SSLC certificate (date-of-birth proof), your category certificate in the prescribed Government of India format, a government photo ID copy and the Demand Draft — any of these missing forfeits your claim. If you are already a regular employee of CSIR, a government department, an autonomous or statutory body, a university or a PSU, you must also enclose an NOC and a Vigilance Clearance Certificate from your employer, failing which your candidature will not be considered at all.
Three things cancel a candidature even after selection: any mismatch between your form and your original documents at verification, any false or suppressed information, and canvassing or bringing influence of any kind, which is treated as an outright disqualification. Write your name and father’s name on the back of the DD. CSIR-NAL is not responsible for postal delays, so post at least a week early.
