DRDO CEPTAM Technician (DRTC) Recruitment: Complete Guide for ITI and Diploma Holders

DRDO isn't just for scientists and engineers. The organization employs thousands of technicians across its 50+ laboratories, and the recruitment happens through CEPTAM — Centre for Personnel Talent Management. If you have an ITI certificate or a diploma, this is one of the best technical positions you can land in the government sector.

DRDO CEPTAM recruits Technician A (entry level) and Senior Technician A positions. These aren't just "helper" roles — technicians in DRDO work directly on defence research projects, operate sophisticated equipment, and contribute to the country's strategic programs.

What is CEPTAM?

CEPTAM (Centre for Personnel Talent Management) is DRDO's dedicated recruitment body. It conducts exams for non-scientist positions including:

• Technician A (DRTC — DRDO Recruitment Technician Cadre)


• Senior Technical Assistant B (STA-B)


• Admin & Allied posts

This article focuses specifically on the Technician A recruitment, which is the largest recruitment drive DRDO conducts — often 1,000+ posts in a single cycle.

Eligibility Criteria

For Technician A:

• ITI/NTC/NAC certificate in the relevant trade from a recognized institute
• OR 10th pass + ITI in the relevant trade

Trades typically recruited: Fitter, Turner, Machinist, Welder, Electrician, Electronics Mechanic, Instrument Mechanic, Carpenter, Painter, Plumber, Refrigeration & AC, COPA (Computer Operator & Programming Assistant), Draughtsman (Mechanical/Civil), Chemical Plant Attendant, Laboratory Assistant Age Limit:

• 18–28 years for General category
• OBC: +3 years, SC/ST: +5 years, PwD: +10 years

For Senior Technician A:

• 3-year Diploma in the relevant engineering discipline
• OR B.Sc. in relevant science discipline
• Age: 18–28 years (same relaxations)

Salary and Benefits

Post	Pay Level (7th CPC)	Basic Pay	Approx. Gross Monthly
Technician A	Level 2	₹19,900	₹30,000–₹35,000
Senior Technician A	Level 4	₹25,500	₹38,000–₹44,000

Beyond the basic salary, DRDO technicians get:

• Dearness Allowance (currently ~55% of basic)
• HRA (depends on city classification of the lab)
• Transport Allowance
• Professional Update Allowance — unique to DRDO, meant for buying books/journals
• Canteen subsidy in most labs
• Medical facilities through DRDO's own medical centers or CGHS

For an ITI holder joining as Technician A, drawing ₹30,000+ per month from the start is quite good. After 5–7 years with increments and DA revisions, this crosses ₹45,000 easily.

Selection Process

Tier 1 — Computer Based Test (CBT)

Section	Questions	Marks
Quantitative Ability / Aptitude	20	20
General Intelligence & Reasoning	25	25
General Awareness	15	15
English Language	10	10
General Science	10	10
Total	80	80

Duration: 90 minutes. Negative marking: 0.25 marks per wrong answer.

Tier 2 — Trade/Discipline Test

This is where your ITI/diploma knowledge matters. The test covers:

• Theory and practical concepts of your specific trade


• Workshop technology


• Safety practices


• Technical drawing/blueprints (for relevant trades)

Important: Tier 2 is qualifying. Your Tier 1 score determines the final merit list. But you must score the minimum qualifying marks in Tier 2 to be considered.

Document Verification and Medical

Standard government process — original certificates, caste certificate if applicable, medical fitness examination.

Where Will You Be Posted?

This is actually one of the exciting parts. DRDO has laboratories across India working on cutting-edge defence technology:

Lab	Location	Work Area
DRDL	Hyderabad	Missile systems
ARDE	Pune	Armaments and explosives
DEBEL	Bangalore	Biomedical engineering
SSPL	Delhi	Semiconductor devices
HEMRL	Pune	High energy materials
RCI	Hyderabad	Missile guidance systems
CAIR	Bangalore	Artificial intelligence
NPOL	Kochi	Naval sonar systems
DEAL	Dehradun	Electronics
DMRL	Hyderabad	Metallurgy
TBRL	Chandigarh	Terminal ballistics
DIPR	Delhi	Fire research

Your posting depends on the trade and vacancies. An electronics mechanic might end up at SSPL Delhi working on semiconductor fabrication, while a fitter could be posted to ARDE Pune working on weapon system prototyping.

You don't get to choose initially, but DRDO does consider transfer requests after completing the initial posting period.

How to Prepare

Tier 1 Preparation

The general section is similar in difficulty to SSC MTS or Railway Group D. Don't overthink it:

Quantitative Aptitude: Basic arithmetic — percentage, ratio, profit-loss, time-speed-distance, simple and compound interest. NCERT Class 10 maths is more than sufficient. Reasoning: Pattern recognition, series completion, coding-decoding, analogies, blood relations, direction sense. Practice 2–3 chapters daily from any standard reasoning book. General Awareness: Focus on current affairs (last 6 months), basic science facts, Indian geography, and important government schemes. Read a daily newspaper — even 15 minutes is enough. English: Sentence correction, fill in the blanks, reading comprehension. Basic grammar rules and a reasonable vocabulary will do.

Tier 2 (Trade Test) Preparation

This is where most candidates either shine or fall flat. Review your entire ITI syllabus — not just the theory, but practical applications.

• Fitter/Turner/Machinist: Measurements, tolerances, cutting tools, machine operations, fits and limits, workshop calculations
• Electrician: Wiring, circuit theory, motors, transformers, earthing, safety regulations, NEC codes
• Electronics: Semiconductor devices, digital circuits, PCB assembly, testing equipment, signal processing basics
• COPA: Computer fundamentals, networking basics, operating systems, MS Office, basic programming concepts

Use NIMI (National Instructional Media Institute) pattern books — these are the standard reference for ITI trade theory across India.

Important Tips from Past Selections

1. Trade test cutoff is low — typically 40% for General and 35% for reserved categories. Don't stress about it if you genuinely know your trade.

1. Tier 1 is what decides your rank. Focus 70% of your preparation time here. The general aptitude section is where most candidates can improve quickly.

1. CEPTAM exams happen every 1–2 years with large vacancy counts (800–1500 posts). When the notification drops, you usually get 4–6 weeks to apply and then another 2–3 months before the exam. Use this window wisely.

1. Zone preference matters. You'll be asked to choose zones during application. Research which labs are in each zone and what trades they need. If you prefer Bangalore, know that DRDO has multiple labs there (CAIR, DEBEL, ADE, GTRE).

1. Medical standards are normal — no special physical requirements like defence or police. Standard government medical fitness is sufficient.

Career Growth After Joining

Technician A is just the starting point. The promotion ladder:

1. Technician A (Level 2) → Entry
2. Technician B (Level 4) → After ~5 years
3. Technician C (Level 5) → After ~12 years
4. Senior Technician (Level 6) → Senior positions

Additionally, DRDO encourages further education. If you complete a degree while in service, you can appear for departmental exams and move to the Scientific/Technical cadre — a significant jump in pay and responsibilities.

Many current DRDO scientists started as technicians, completed their engineering degrees through evening/distance courses, and then moved up. The organization genuinely rewards capability.

Final Thoughts

For ITI and diploma holders, DRDO CEPTAM Technician recruitment is arguably the best government technical job available. You're not just turning screws in a workshop — you're contributing to missile systems, radar technology, naval systems, and next-generation defence equipment. The salary is fair, the work is meaningful, and the career growth exists for those who pursue it.

Watch drdo.gov.in and the CEPTAM portal for notifications. When a recruitment cycle opens, apply immediately — the window closes fast.
