DRDO Recruitment Eligibility 2026: Complete Post-wise Guide Age Limit, Qualifications & GATE Score

The DRDO Recruitment Eligibility criteria for 2026 state that the candidates should be Indian Nationals only. For the Scientist ‘B’ category, a First Class Bachelor’s Degree in Engineering or Technology along with a valid GATE score is necessary, with a maximum age limit of 28 years (General). For the CEPTAM category (STA-B), a Diploma or B.Sc. is required, and for Technician-A, Class 10th along with an ITI certificate is required.

Comprehensive Overview of DRDO Recruitment Eligibility

Let’s face it, decoding government recruitment notices sometimes feels like solving a cipher. However, when it comes to Defence Research and Development Organisation (DRDO), clarity is your greatest asset. The organisation strictly follows specific eligibility criteria for its two major recruitment panels: RAC (Recruitment & Assessment Centre) and CEPTAM (Centre for Personnel Talent Management). Familiarising yourself with the DRDO Recruitment Eligibility criteria applicable to your desired job is the first step to a successful recruitment process.

This guide breaks down the universal requirements applicable across all cadres, primarily focusing on nationality and mandatory prerequisites. If you are eyeing the upcoming DRDO Recruitment 2026, you need to know exactly where you stand regarding your DRDO Recruitment Eligibility status before you start your prep.

To satisfy the DRDO Recruitment Eligibility criteria, the candidate must be an Indian National. Foreign Nationals are not eligible in general, but certain notifications from the government may override this criterion. Apart from this, the candidate must have the required educational qualification from accredited universities or institutes. The organization maintains a strict cutoff date for age and educational qualification; all DRDO Recruitment Eligibility criteria must be satisfied by the last date of the advertisement. Candidates awaiting final results are not eligible in general, unless otherwise specified in certain recruitment notifications.

DRDO Scientist B Eligibility for RAC Recruitment

If you are aspiring to become a Class I Gazetted Officer, you are targeting the Scientist ‘B’ position. This is the highest entry level for engineers and scientists. The DRDO Recruitment Eligibility criteria for Scientist ‘B’ can be fulfilled by having a First Class Bachelor’s Degree in Engineering or Technology (B.E./B.Tech) in the respective field.

Applicants also need to have a valid GATE score for selection. But there is an exception, which is called the “Golden Ticket” exception. Students from IITs/NITs with an aggregate of 80% or more can fulfill the DRDO Recruitment Eligibility criteria without a GATE score in certain recruitment drives.

Aspirants who are targeting this level need to conform to certain standards. The first criterion is the educational requirement, which is non-negotiable. It requires a First Class Degree in Engineering, Technology, or Science (M.Sc.) in Electronics, Mechanical, or Computer Science disciplines. For certain technical posts in Psychology or Physics, the Master’s degree is the basic educational requirement to fulfill the DRDO Recruitment Eligibility criteria.

The Role of GATE in Eligibility

The selection procedure is heavily dependent on the GATE score. For the majority of the posts, a valid GATE score in the relevant paper is an absolute requirement for the initial screening process. It is important to note that in order to retain the DRDO Recruitment Eligibility, the GATE score must be valid on the date of closing of the application. Those who do not provide proof of validity will be disqualified instantly during the document verification process.

For a deeper dive into how this specific role functions and what it takes to get there, read our breakdown on how to become a DRDO Scientist.

Essential Academic Criteria for Scientist B

• Engineering Disciplines: At least 60% marks or equivalent CGPA in B.E./B.Tech.
• Science Disciplines: First Class Master’s Degree (M.Sc.) with NET/GATE qualification in some cases.
• Knowledge Certification: Proficiency in specific technical domains may be tested during the interview.

DRDO CEPTAM Eligibility for STA-B and Technician A

While RAC handles the scientists, CEPTAM handles the technical backbone of the organization. The DRDO Recruitment Eligibility for CEPTAM differs significantly by post and is strictly trade-specific.

• Senior Technical Assistant-B (STA-B): Requires a three-year Diploma in Engineering or a B.Sc.
• Technician-A: Demands a Class 10 pass certificate combined with a valid ITI certification in the relevant trade.

For the Senior Technical Assistant-B (STA-B) position, the required qualification is that the candidate should have a three-year Diploma in Engineering disciplines such as ECE, Mechanical, Electrical, or a Bachelor of Science (B.Sc.) in subjects such as Chemistry, Physics, or Mathematics. This is necessary for DRDO Recruitment Eligibility.

Important Note: Candidates with a B.E. or B.Tech. degree are generally not eligible for STA-B positions unless they have the underlying Diploma. This position is specifically reserved for Diploma/Science holders. If you have a B.Tech. degree, you should prepare for Scientist B or other higher-level exams because your DRDO Recruitment Eligibility may not be suitable for STA-B positions.

For the Technician-A (Tech-A) category, the educational requirement is based on vocational training. The candidate must have passed Class 10 (Matriculation) and must hold a certificate from a recognized Industrial Training Institute (ITI). The ITI certificate must be in the specific trade advertised in the notification (for instance, Fitter, Welder, Electrician). The candidate must ensure that his/her National Trade Certificate (NTC) or National Apprenticeship Certificate (NAC) is issued by NCVT/SCVT before the last date of application, which is required for DRDO Recruitment Eligibility.

Quick Summary of CEPTAM Posts

Age Limit and Relaxation Norms Across Posts

Age is often the heartbreak factor in government exams. Adhering to the age limit is a critical component of DRDO Recruitment Eligibility.

The maximum age limit for Scientist ‘B’ is 28 years. This is also strictly computed as of the last date of online application submission. For CEPTAM posts, STA-B, and Tech-A, the age range is normally 18 to 28 years. Some administrative positions (A&A) may have different age limits, which can extend up to 27 or 30 years depending on the service rules.

Age relaxation is applied according to Government of India directives, which directly impacts your calculated DRDO Recruitment Eligibility:

• OBC (Non-Creamy Layer): 3-year relaxation (Effective limit: 31 years for Scientist B).
• SC/ST: 5-year relaxation (Effective limit: 33 years).
• PwBD/Ex-Servicemen: Eligible for further relaxations (typically 10 years + category relaxation).

Applicants seeking relaxation must produce valid caste or disability certificates in the prescribed central government format at the time of verification to prove their DRDO Recruitment Eligibility.

Many candidates look at the rigorous requirements and wonder if it’s worth the effort. Once you see the perks detailed in the DRDO Salary structure, you’ll realize why thousands compete for these spots.

Critical Medical Standards and Physical Fitness

You might have the brains, but do you have the fitness? Candidates must be in good mental and physical health and free from any deformity that interferes with duty.

While educational qualification gets the most attention, meeting the medical standards is a hidden but vital aspect of DRDO Recruitment Eligibility. Upon final selection, candidates undergo a thorough medical examination by a designated Medical Board. The board assesses physical fitness to ensure the candidate can perform duties in demanding environments, including high-altitude or field stations.

Common grounds for rejection include:

• Evidence of chronic diseases.
• Significant physical deformities.
• Vision issues that exceed permissible correction limits (Color blindness is a strict “No” for certain technical roles).

A candidate with temporary unfit status may be given a chance to recover, but permanent unfit status results in the immediate cancellation of candidature. It is always a good idea to have a preliminary check-up if you feel that you have some underlying condition that might impact your DRDO Recruitment Eligibility.

Final Year Student Eligibility Status

This is the most frequently asked question: “I am in my final semester, can I apply?”

The short answer is usually No.

Final year students are NOT eligible for DRDO recruitment unless they have the final degree or provisional certificate by the closing date of the application. This is because the requirement is the possession of the qualification, not the completion of the exams.

Unlike other competitive exams, DRDO recruitment notifications (both RAC and CEPTAM) usually specify that the educational qualification should be completed by the application deadline. This means that the candidate should have the final mark sheet or provisional degree in hand to qualify for DRDO Recruitment Eligibility.

A candidate in the final semester and whose results are declared after the closing date does not qualify for the eligibility criteria. There is no scope for “appearing” candidates to apply provisionally. This is because the rule is very strict to ensure that the recruitment process does not get delayed due to pending results of the candidates. Hence, final year candidates should check the “Crucial Date of Eligibility” in the official notification before applying.

Impact of GATE Score on Recruitment Analysis

For Scientist B, the GATE score is the primary shortlisting tool, carrying significant weightage (often 80%) in the final selection matrix. A high GATE score acts as a gatekeeper for DRDO Recruitment Eligibility, and mere qualification in GATE without a high rank is often insufficient for interview calls.

The GATE score is not just an eligibility checkbox; it is the most significant differentiator in the Scientist B selection process. While the basic Scientist B eligibility requires a valid score, the cutoffs for interview calls are extremely competitive. For popular branches like Computer Science and Electronics, candidates often need a score in the top percentile to secure an interview.

In recent recruitment cycles, the selection weightage has been split:

• GATE Score: 80%
• Personal Interview: 20%

This heavy reliance on GATE means that a candidate’s performance in the national level exam directly dictates their success probability. Candidates applying under the “Direct Recruitment” scheme must ensure their GATE paper code matches exactly with the discipline they are applying for. Mismatched codes (e.g., an Electrical Engineering graduate taking the Instrumentation paper) can sometimes lead to issues with DRDO Recruitment Eligibility depending on the specific notification rules.

Application Process and Post-Wise Criteria

To apply online, the candidate has to register on the concerned RAC or CEPTAM website, making sure that all the post-wise requirements in terms of age, qualification, and category proof are satisfied. Any mismatch between the details entered in the application form and the actual documents leads to automatic rejection of the application.

To successfully complete the apply online procedure, the candidate has to be very particular about post-wise requirements to make sure that the DRDO Recruitment Eligibility is checked without any problems. The candidate has to log in to the RAC website for Scientist B recruitment or the CEPTAM website for staff recruitment and enter the details in the application form carefully. The website usually has filters that do not allow the candidate to apply if the date of birth or date of completion of the degree is beyond the desired limit.

Pro Tip: If you are also looking at state-level engineering exams as a backup, such as DHBVN AE Recruitment 2026, you will find that DRDO’s documentation requirements are generally stricter regarding DRDO Recruitment Eligibility.

Before final submission, ensure that your educational qualification fields are accurately reflected in your certificates. Scanned copies of certificates with blurry images or misclassified certificates may render your DRDO Recruitment Eligibility invalid. In addition, candidates who are already working in the Government or PSU sectors need to procure a “No Objection Certificate” (NOC) from their respective employers. Lack of NOC submission during the interview and document verification process is a common reason for disqualification, irrespective of the candidate’s eligibility.
