The Defence Research and Development Organisation (DRDO), through its Centre for Personnel Talent Management (CEPTAM), conducts recruitment for Senior Technical Assistant-B (STA-B) and Technician-A posts across its numerous laboratories and establishments spread throughout India. DRDO CEPTAM recruitment is one of the most sought-after technical government job opportunities for diploma holders, B.Sc. graduates, and ITI-qualified candidates, offering the chance to work on India's premier defence research and development programmes. This guide covers the complete DRDO CEPTAM syllabus for STA-B and Technician-A posts, the Tier 1 and Tier 2 exam pattern, marking scheme, and a practical preparation strategy for aspirants.

DRDO itself is one of the largest and most prestigious government research organisations in India, operating a network of more than fifty laboratories and establishments across the country, spanning domains from missile technology and combat aircraft systems to naval warfare electronics, materials science, life sciences, and advanced computing. DRDO's Centre for Personnel Talent Management, or CEPTAM, was specifically established as a dedicated recruitment wing to standardise and streamline the hiring process for technical cadre posts across this extensive laboratory network, since individual DRDO labs previously conducted separate localised recruitment drives, which made the process inconsistent and harder for candidates to track. Understanding this centralised structure helps candidates appreciate why a single CEPTAM notification often covers vacancies across dozens of different DRDO laboratories located in cities ranging from Delhi, Bengaluru, and Hyderabad to smaller establishment towns; candidates should carefully review the specific laboratory and location options listed against each post code in the official notification, since posting location can vary significantly even within the same STA-B or Technician-A recruitment cycle.

DRDO CEPTAM recruitment cycles are numbered sequentially — recent cycles have been referred to as CEPTAM 10, CEPTAM 11, and so on — with each cycle announcing vacancies across STA-B and Technician-A categories, often numbering in the hundreds across various engineering, science, and technical trade disciplines. CEPTAM 11, for instance, announced 764 vacancies (561 STA-B and 203 Technician-A) across DRDO's Defence Research and Technical Cadre. Understanding the general structure of these cycles helps candidates recognise that DRDO CEPTAM recruitment is a recurring opportunity rather than a one-time event, making sustained exam preparation worthwhile even between active recruitment windows.

DRDO CEPTAM Exam Pattern 2026

The DRDO CEPTAM selection process for both STA-B and Technician-A posts is conducted entirely through Computer-Based Test (CBT) mode, structured across two tiers.

Tier 1 (Common Screening Exam)

  • Conducted in Computer-Based Test (CBT) mode
  • Consists of 150 objective-type questions carrying 150 marks
  • Duration of 2 hours (120 minutes)
  • Covers General Science, General Intelligence & Reasoning, Quantitative Aptitude/General Mathematics, and General English
  • Negative marking of 0.25 marks is applicable for each incorrect answer
  • The Tier 1 paper is common in structure for both STA-B and Technician-A posts, though exact subject weightage may differ slightly by post category
  • Minimum qualifying marks: 40% for UR/OBC/EWS candidates, 35% for SC/ST/PwBD candidates

Tier 2 (Post-Specific Stage)

For STA-B posts:

  • A subject-specific/discipline-specific Computer-Based Test
  • Carries 100 marks with a duration of 90 minutes
  • Tests in-depth technical knowledge in the candidate's specific engineering or science discipline (Diploma or B.Sc. level, depending on the post)
  • Followed by a Personality Test, which is qualifying in nature and does not carry marks toward the final merit list
  • Final merit for STA-B is determined based on combined Tier 1 and Tier 2 (subject-specific) marks

For Technician-A posts:

  • A Trade Test, conducted at ITI level relevant to the candidate's specific trade
  • The Trade Test is qualifying in nature — candidates must clear it to be considered for selection
  • Minimum qualifying marks for the Trade Test: 50% for UR/OBC/EWS candidates, 45% for SC/ST/PwBD candidates
  • Final merit for Technician-A is primarily based on Tier 1 performance, with the Trade Test serving as a qualifying gate rather than a merit-contributing component

Candidates should always verify the exact marks distribution, negative marking policy, and qualifying criteria from the official notification for their specific CEPTAM cycle, since DRDO has made minor adjustments to these parameters across different recruitment cycles.

DRDO CEPTAM Tier 2 Syllabus for STA-B (Discipline-Wise)

The Tier 2 exam for STA-B is entirely discipline-specific, meaning the actual syllabus depends on which engineering or science discipline the candidate has applied for. Common disciplines include:

  • Mechanical Engineering: Thermodynamics, Fluid Mechanics, Strength of Materials, Manufacturing Processes, Machine Design, Theory of Machines
  • Electrical/Electronics Engineering: Circuit Theory, Electrical Machines, Power Systems, Control Systems, Digital Electronics, Communication Systems
  • Computer Science/IT: Data Structures, Programming Fundamentals (C/C++/Java), Database Management, Computer Networks, Operating Systems
  • Civil Engineering: Structural Engineering, Building Materials, Surveying, Construction Technology, Soil Mechanics
  • Chemistry/Chemical Engineering: Analytical Chemistry, Organic and Inorganic Chemistry, Chemical Process Technology
  • Physics/Instrumentation: Applied Physics, Electronic Instrumentation, Measurement Systems

Candidates should study their specific discipline syllabus at the Diploma or B.Sc. level, depending on the minimum qualification prescribed for their applied post, since DRDO CEPTAM does not publish a single unified Tier 2 syllabus — each discipline has its own detailed topic list released alongside the official notification.

Given that Tier 2 for STA-B posts is entirely discipline-specific with no standardised cross-discipline syllabus, candidates are strongly advised to download the exact discipline-wise syllabus PDF released alongside each specific CEPTAM notification, rather than relying on generic engineering preparation material available online, since DRDO's technical questions at Tier 2 are often set with a specific emphasis on defence and applied research contexts that general engineering coaching material does not always cover in adequate depth. For example, a Mechanical Engineering STA-B candidate may find Tier 2 questions weighted more heavily toward manufacturing and materials topics relevant to defence hardware production than toward purely theoretical mechanical engineering concepts more common in campus placement-style preparation material.

DRDO CEPTAM Eligibility Overview

  • STA-B: Diploma or B.Sc. in a relevant engineering/science discipline from a recognised institution
  • Technician-A: 10th pass with an ITI certificate (NCVT/SCVT) in the relevant trade from a recognised institution

Both posts fall under DRDO's Defence Research and Technical Cadre (DRTC), and candidates selected are posted across DRDO's network of laboratories working on defence technologies spanning aeronautics, missiles, combat vehicles, naval systems, electronics, materials science, and life sciences.

Candidates should also understand that DRDO CEPTAM recruitment is distinct from DRDO Scientist-B recruitment, which follows an entirely separate selection process, typically through GATE scores or a dedicated DRDO Scientist Entry Test, for candidates holding a full engineering degree or postgraduate qualification. STA-B and Technician-A posts under CEPTAM are technical support and technical assistant roles rather than scientist-level research positions, though they still offer genuine hands-on involvement in DRDO project work and a clear long-term career within the organisation, including internal promotional avenues over time for candidates who perform well and pursue further qualifications while in service. This distinction matters for candidates deciding which DRDO entry route best matches their current qualification level and career stage, since applying under the wrong category due to confusion between Scientist-B and CEPTAM technical cadre posts can lead to an avoidable rejection at the application stage.

Why DRDO CEPTAM Is a Sought-After Government Technical Job

DRDO offers a genuinely distinctive career path compared to many other technical government recruitment exams, since selected candidates work directly within India's defence research ecosystem, often on projects with direct national security significance. Beyond the job security and central government pay scale that come with any DRDO appointment, STA-B and Technician-A roles offer meaningful hands-on technical exposure — candidates work alongside DRDO scientists and engineers on live research and development projects rather than purely administrative or clerical technical support functions. This distinguishes DRDO CEPTAM posts from many comparable technical assistant roles in other government departments, and is a significant part of why competition for these posts remains consistently high across recruitment cycles, despite the relatively technical and demanding nature of the Tier 2 discipline-specific examination.

DRDO CEPTAM Preparation Strategy

  • Build a strong Tier 1 foundation first, since it is common across disciplines and qualifies you for the discipline-specific Tier 2 stage regardless of your specific engineering or science background
  • For General Science, revise 10+2-level Physics, Chemistry, and Biology concepts systematically rather than relying only on random current-affairs-style science questions
  • Practice Quantitative Aptitude questions daily, since this section often decides the Tier 1 qualifying margin given the relatively high competition for CEPTAM posts
  • For Tier 2, obtain the exact discipline-specific syllabus PDF released with the official notification for your chosen post, and study from standard Diploma-level or B.Sc.-level textbooks for that discipline rather than generic engineering compilations
  • Since there is negative marking of 0.25 per wrong answer in Tier 1, avoid random guessing — attempt questions where you can eliminate at least two incorrect options confidently
  • For Technician-A candidates, practical hands-on trade skill practice matters as much as theoretical revision, since the Trade Test is conducted at genuine ITI proficiency level
  • Solve previous years' DRDO CEPTAM Tier 1 question papers to understand the exact difficulty level, since DRDO's General Science and Reasoning sections tend to be slightly more technical in flavour than similar sections in non-technical government exams
  • Stay updated with the official DRDO CEPTAM portal for notification updates, since recruitment cycles and exact vacancy numbers vary significantly between cycles

Candidates preparing for Technician-A trade tests should similarly seek out the exact trade-specific practical syllabus for their applied trade — whether Fitter, Electrician, Machinist, or another ITI discipline — since the trade test evaluates hands-on proficiency against defence-sector-relevant equipment and procedures, which can differ meaningfully from standard ITI training centre practice equipment. Reaching out to DRDO alumni or serving Technician-A staff through professional networks, where possible, can also provide practical insight into the specific equipment and procedures commonly tested at a given laboratory's trade test, which formal syllabus documents alone rarely capture in full detail, and is well worth the effort for serious aspirants.
