For every diploma and ITI-qualified candidate dreaming of a stable, respected government career, DRDO recruitment genuinely offers something special — the chance to work directly with India’s premier defence research organisation, contributing to technologies that shape national security. With 764 vacancies announced for Senior Technical Assistant-B and Technician-A posts under the DRDO Technical Cadre, this cycle represents a genuinely significant opportunity for engineering and technical candidates across the country. But here’s what makes this exam genuinely tricky to prepare for correctly: the selection process differs meaningfully between STA-B and Tech-A posts, with Technician-A candidates needing to clear an additional Trade Test that STA-B aspirants don’t face, while STA-B candidates go through a Personality Test that Technician-A candidates skip entirely. Understanding exactly which path applies to you before you start preparing is what prevents wasted effort on stages that may not even be part of your specific recruitment journey.
Let’s break down everything you need to know.

Since Technician-A and STA-B follow genuinely different post-Tier I paths, confirming which specific post you’re targeting shapes exactly which additional stages you need to prepare for beyond the common written exams.
Understanding the Selection Process for STA-B and Technician-A
DRDO CEPTAM 11 recruitment runs through a structure that’s common at the start but genuinely diverges depending on your target post.
For Technician-A, the process includes:
- Tier I — the common screening test
- Trade Test — a mandatory, qualifying practical skill assessment
For Senior Technical Assistant-B (STA-B), the process includes:
- Tier I — the common screening test
- Tier II, Part II — subject-specific technical test
- Personality Test — a qualifying stage assessing overall suitability
Since Technician-A candidates move directly from Tier I into a practical Trade Test, while STA-B candidates continue through an additional technical written stage followed by a Personality Test, your preparation timeline and depth genuinely need to reflect which specific path applies to your target post.
Tier I Exam Pattern
Tier I serves as the common screening stage for both STA-B and Technician-A candidates, conducted through a Computer-Based Test consisting of 150 questions worth 150 marks, to be completed within 120 minutes.
The Tier I syllabus covers four core subjects:
- General Science
- English
- Quantitative Aptitude
- Reasoning
Negative marking applies at 0.25 marks deducted per wrong answer, and candidates need to clear the qualifying threshold — 40% for UR, OBC, and EWS candidates, and 35% for SC, ST, and PwBD candidates — to advance to the next stage of the selection process.
General Science Syllabus
This section tests foundational scientific knowledge relevant to a technical role, covering basic concepts from physics, chemistry, and biology at a level appropriate for diploma and ITI-qualified candidates. Since this section often overlaps with core engineering fundamentals, candidates with a strong technical educational background typically find this section manageable with consistent revision.
English Syllabus
This section tests grammar, vocabulary, and comprehension skills, covering:
- Reading comprehension
- Grammar and sentence correction
- Vocabulary-based questions (synonyms, antonyms)
- Error spotting
- Fill in the blanks
Since strong English communication genuinely matters for technical documentation and workplace communication, building consistent grammar practice benefits both your exam performance and your eventual job responsibilities.
Quantitative Aptitude and Numerical Ability Syllabus
This section tests calculation speed and applied mathematical reasoning, covering a genuinely extensive range of topics including:
- Statements and arguments, statements and assumptions
- Causes and effects, assertion and reason
- Statement and conclusion, course of action
- Syllogism
- Average, ratio, HCF, LCM, proportion, partnership
- Number system
- Speed, distance, and time
- Probability
- Problems on ages
- Work and time
- Inequalities, including quadratic equations
Given how extensive this topic list is, candidates benefit from prioritising high-frequency areas like average, ratio, number system, and time-and-work problems, since these tend to appear consistently across similar competitive exams, rather than spreading preparation evenly across every single sub-topic.
Reasoning Syllabus
This section evaluates logical and analytical thinking, covering both verbal reasoning formats — like syllogism and statement-based reasoning — alongside standard logical reasoning topics including analogies, series completion, and coding-decoding. Since this section rewards consistent practice more than memorisation, regular timed practice sessions genuinely build the speed and accuracy needed within the fixed exam duration.
Tier II, Part II: Subject-Specific Technical Test (STA-B Only)
Candidates applying for STA-B posts who clear Tier I move to Tier II, Part II, which is conducted through a Computer-Based Test focusing entirely on subject-specific technical knowledge relevant to their particular discipline. Each question in this stage carries 1 mark, with the same 0.25 negative marking scheme applied for incorrect answers.
Since this stage tests genuinely specialised technical content specific to your engineering or technical discipline, candidates need to revise their core diploma or degree coursework thoroughly, rather than assuming general aptitude preparation from Tier I automatically covers this considerably more specialised component.
Trade Test: The Practical Stage for Technician-A
Candidates applying for Technician-A posts, after clearing Tier I, must appear for a mandatory Trade Test — a qualifying, practical skill assessment relevant to their specific trade. Since this stage is genuinely hands-on rather than written, candidates need dedicated practical skill preparation specific to their trade, alongside their Tier I written exam preparation, rather than assuming written exam success alone secures their selection.
Given that this Trade Test is qualifying in nature, candidates need to clear it comfortably, though it doesn’t directly add to their merit ranking the way Tier I marks do.
Personality Test: The Final Stage for STA-B
STA-B candidates who clear both Tier I and Tier II, Part II move to a Personality Test, which is qualifying in nature. This stage assesses overall suitability, communication skills, and professional readiness for the Senior Technical Assistant role, though the final merit list is prepared based on combined Tier I and Tier II, Part II marks rather than the Personality Test score itself.
Understanding DRDO CEPTAM MTS: A Related but Separate Recruitment
Beyond STA-B and Technician-A, DRDO also conducts separate recruitment for Multi Tasking Staff (MTS) posts under CEPTAM, following a somewhat different structure. The DRDO CEPTAM MTS Tier 1 exam is objective in nature, conducted over a 90-minute duration, covering General Science, General Mathematics, English, and Reasoning — broadly similar subject themes to STA-B and Technician-A’s Tier I, but calibrated at a different eligibility and difficulty level suited to MTS-level positions.
Since MTS recruitment runs as a distinct cycle from STA-B and Technician-A, candidates should confirm which specific CEPTAM recruitment notification applies to their eligibility and career goal before committing to a particular preparation plan.
Why Understanding Your Specific Post Path Matters So Much
A genuinely common source of confusion among DRDO CEPTAM aspirants is preparing generically without confirming which post-specific path — STA-B’s technical written test and Personality Test, or Technician-A’s practical Trade Test — actually applies to them. Since these two paths diverge significantly after Tier I, candidates need to confirm their target post early and structure their post-Tier I preparation accordingly, rather than assuming a uniform preparation approach works identically for both.
Building an Effective Preparation Strategy
Given the structure spanning common Tier I content followed by genuinely different subsequent stages, your preparation strategy needs to address both the shared foundation and your specific post’s unique requirements.
In your initial preparation phase, build strong fundamentals across General Science, English, Quantitative Aptitude, and Reasoning, since these form the common Tier I foundation for both STA-B and Technician-A candidates. Given the negative marking scheme, practice with genuine confidence calibration, attempting questions where you have reasonable certainty rather than guessing liberally across uncertain areas.
If you’re targeting STA-B, once you’ve built solid Tier I readiness, shift meaningful preparation time toward your specific technical subject for Tier II, Part II, revising your core diploma or degree coursework thoroughly. Simultaneously, begin building genuine communication confidence for your eventual Personality Test, since this stage assesses professional suitability beyond pure technical knowledge.
If you’re targeting Technician-A, dedicate consistent, hands-on practice time to your specific trade’s practical skills throughout your preparation period, rather than treating the Trade Test as a formality to address only after clearing Tier I, since practical proficiency genuinely takes sustained practice to build confidently.
FAQs
Q1. Since STA-B and Technician-A follow different paths after Tier I, how do I know which specific post to target?
Your choice should align with your genuine educational qualification and career interest — STA-B typically suits candidates seeking a role with deeper technical assessment and eventual personality-based evaluation, while Technician-A suits candidates whose strength lies in practical, hands-on trade skills, so reviewing the official notification’s specific eligibility criteria for each post helps clarify which path genuinely matches your background.
Q2. Since the Trade Test for Technician-A is qualifying and doesn’t add to merit, is it safe to prepare for it casually?
Not entirely — while it doesn’t directly boost your merit ranking, failing to clear this qualifying stage disqualifies you regardless of how well you performed in Tier I, so genuine, sustained practical practice throughout your preparation period remains essential rather than optional.
Q3. How should I prioritise my preparation time across the four Tier I subjects given the negative marking scheme?
Given the 0.25 mark penalty for wrong answers, prioritise building genuine confidence and accuracy across Quantitative Aptitude and Reasoning specifically, since these sections cover the most extensive topic range and reward consistent practice, while maintaining steady preparation in General Science and English to ensure balanced performance across all four subjects.
Q4. Is DRDO CEPTAM MTS the same recruitment as STA-B and Technician-A, just for a different post level?
No, MTS recruitment runs as a genuinely separate CEPTAM cycle with its own notification, eligibility criteria, and exam structure, distinct from the STA-B and Technician-A recruitment under CEPTAM 11, so candidates should confirm which specific notification and post category matches their eligibility before preparing.
