About this exam

DRDO CEPTAM Tech-A is the recruitment examination through which the Defence Research and Development Organisation (DRDO) fills Technician 'A' posts in its laboratories and establishments across India. The qualification suits ITI certificate holders and candidates with a technical background who want a stable technical support role in defence research - maintaining equipment, assisting scientists and engineers, and handling day-to-day technical work in workshops and labs. The computer-based test mixes aptitude with trade knowledge: quantitative aptitude, reasoning, general awareness and general science, English, and technical questions drawn from the trade you apply for, such as Fitter, Electrician, Welder, Machinist, Turner, or Electronics and Instrumentation. Preparation should be trade-first. Lock down your ITI syllabus - workshop calculations, measuring instruments, safety, materials, and trade-specific procedures - because technical accuracy is where prepared candidates separate. Then build a steady routine for aptitude: number series, ratios, percentages, and reasoning puzzles reward daily short practice more than cramming. Read a newspaper or standard science text for general awareness, and practise English usage lightly but consistently. Take timed mock tests to get used to the CBT interface and to pace yourself. Always confirm the current syllabus, eligibility, and important dates on the official DRDO CEPTAM portal before applying.

What you'll study

Common questions

About DRDO CEPTAM Tech-A preparation

What is the CEPTAM Tech-A exam format?

It is a computer-based test of multiple-choice questions answered on screen. The paper combines aptitude, reasoning, general awareness and science, English, and trade-specific technical questions. DRDO publishes the current number of questions, section structure, and marking scheme in each recruitment notification, so check the official CEPTAM portal for the cycle you are applying to.

Is there negative marking?

Some CEPTAM cycles have applied a penalty for wrong answers while others have not. Because this changes between notifications, do not rely on memory or coaching-forum claims. Read the marking scheme in the official notification for your recruitment year and adjust your guessing strategy accordingly before exam day.

How difficult is the paper?

The aptitude and reasoning sections are moderate, comparable to other technical recruitment tests. The trade section is where the paper becomes demanding, because questions test practical ITI-level knowledge rather than general awareness. Candidates who revise their trade theory thoroughly usually find the paper manageable; those who study only aptitude often fall short.

Can I choose which trade's technical questions I answer?

No. The technical section follows the trade you applied for and were found eligible in. If you applied as a Fitter, expect Fitter questions; an Electrician applicant gets Electrical questions. Study the syllabus prescribed for your trade only, and do not spend time on other trades' material.

How long is the exam, and how many questions are there?

The official body publishes the current question count and duration in the recruitment notification and information brochure, and these have varied between cycles. Rather than relying on second-hand figures, download the latest notification from the DRDO CEPTAM website and note the exact timing before you plan mock-test practice.

What is the selection process after the written test?

Shortlisted candidates normally proceed to document verification and a trade or skill test depending on the post and cycle. Eligibility, physical standards where applicable, and the exact sequence are specified in the official notification. Keep your ITI certificate, marksheets, identity documents, and category certificates ready and consistent with your application details.

Can I retake the exam if I do not qualify?

You may apply again in a future recruitment cycle if you still meet the age and eligibility conditions, since each notification is a fresh recruitment. There is no provision to retake the same cycle's test after attempting it. Check the official notification for age relaxation and eligibility rules before reapplying.

In what order should I prepare?

Start with your trade syllabus, because it carries real weight and is the hardest to pick up late. Add daily short sessions of quantitative aptitude and reasoning, then general science and awareness, and finally English usage. Finish with full-length timed mocks to build speed and familiarise yourself with the computer-based interface.

What mistakes cause candidates to fail?

Common ones: ignoring the trade syllabus in favour of aptitude alone, memorising answers without understanding workshop fundamentals, skipping mock tests and then running out of time, misreading units and measurement questions, and letting documents or application details mismatch. Careless errors in the technical section cost more than lack of knowledge.
