Before you start filling out the CDAC CCAT application form, the first question you need answered is: am I eligible? Every year, thousands of candidates register for CCAT without fully understanding the eligibility criteria — leading to confusion during counselling and, in some cases, wasted application fees. This guide covers every detail about who can apply for CCAT in 2026, what qualifications are accepted, and which courses you can choose based on your academic background.

Basic Eligibility Requirements
CDAC CCAT (Common Computer Admission Test) is conducted by the Centre for Development of Advanced Computing to admit students into its various PG Diploma programs. The fundamental eligibility criteria are straightforward:
- Nationality: Indian citizens as well as foreign nationals can apply. There is no nationality restriction for appearing in the exam.
- Educational Qualification: Candidates must hold a recognized degree (B.E./B.Tech, M.Sc., MCA, or equivalent) from a UGC-recognized university or AICTE-approved institution.
- Minimum Marks: A minimum of 50% aggregate marks (45% for SC/ST candidates) in the qualifying degree is generally required.
- Final-Year Students: Students appearing in their final semester/year of the qualifying degree can also apply, subject to producing the final marksheet at the time of admission.
The eligibility criteria are course-specific — meaning the qualifying degree accepted for PG-DAC is different from what's accepted for PG-DESD. We'll break this down in detail below.
Branch-wise Eligibility — Who Can Apply?
One of the biggest advantages of CDAC is that it doesn't restrict applications to just CS/IT graduates. Engineers, science graduates, and postgraduates from various disciplines can apply. Here's how eligibility works across different branches:
CS / IT / MCA Graduates
If you hold a B.E./B.Tech in Computer Science, Information Technology, Computer Engineering, or an MCA degree, you have the widest range of course options available. You are eligible for virtually all CDAC PG Diploma courses including PG-DAC, PG-DBDA, PG-DAI, and PG-DMC. Your academic background already covers programming, data structures, and OS fundamentals — which means you can leverage your existing knowledge in the CCAT exam as well.
ECE / EEE / E&TC Graduates
Electronics and Communication, Electrical, and Electronics & Telecommunication graduates are eligible for both software-focused and hardware-focused CDAC courses. You can apply for PG-DAC if you want to transition into software development, or choose PG-DESD if you prefer staying closer to your core domain — embedded systems, microcontrollers, and hardware design. Many ECE graduates specifically join CDAC to make the shift from electronics to IT, and PG-DAC is the most popular route for that switch.
Mechanical / Civil / Other Engineering Graduates
Yes, even Mechanical, Civil, Chemical, and other non-CS engineering graduates can apply for CDAC. You are primarily eligible for PG-DAC, which is designed to train candidates in software development from the ground up. While you might not have prior coding experience, CDAC's curriculum is structured to bring everyone up to speed. Thousands of Mechanical and Civil engineers have successfully transitioned into IT careers through CDAC every year.
B.Sc. / BCA / Science Graduates
Candidates with B.Sc. (Computer Science, IT, Electronics, Mathematics, Statistics, or Physics) and BCA degrees are eligible for select CDAC courses — primarily PG-DAC and PG-DBDA. You need to have studied relevant subjects (programming, mathematics, or statistics) as part of your curriculum. Note that a 3-year B.Sc. degree is accepted, but the specific eligibility may vary by course. Always check the official CDAC notification for the exact list of accepted degrees for each course.
MCA / M.Sc. Postgraduates
MCA holders are eligible for most CDAC courses. M.Sc. graduates in Computer Science, IT, Electronics, Mathematics, or Statistics are also eligible for relevant courses. Having a postgraduate degree does not give any additional advantage in the CCAT exam — the exam is the same for everyone — but it broadens the list of courses you can apply for.
Percentage & Marks Requirements
CDAC specifies minimum percentage criteria for admission, not for appearing in CCAT. This is an important distinction:
- General / OBC candidates: Minimum 50% aggregate marks in the qualifying degree
- SC / ST candidates: Minimum 45% aggregate marks in the qualifying degree
There are a few things to keep in mind about percentage calculation:
- Aggregate marks means the overall percentage across all semesters/years of your degree, not just the final year.
- If your university uses a CGPA system, you need to convert it to percentage using your university's official conversion formula. Most universities use a multiplier of 9.5 or 10 (e.g., 7.5 CGPA × 9.5 = 71.25%).
- CDAC may ask for a CGPA-to-percentage conversion certificate from your university during admission.
- Rounding is generally not accepted — if the requirement is 50% and your aggregate is 49.9%, you might face issues during admission verification.
Age Limit
One of the most frequently asked questions about CCAT eligibility is about age restrictions. Here's the good news:
- No upper age limit: CDAC does not impose any maximum age limit for CCAT. Whether you're a fresh graduate or someone with 10 years of work experience looking to upskill, you can apply.
- No minimum age limit: As long as you hold the required qualifying degree, your age is not a barrier.
- Working professionals welcome: Many working professionals in their late 20s and early 30s take CCAT to switch careers or upgrade their skills. CDAC courses are full-time, so you'll need to take a break from work during the 6-month program.
Course-wise Eligibility Mapping
This is the most critical section. Each CDAC PG Diploma course has specific qualifying degree requirements. Here's a comprehensive mapping:
| CDAC Course | Qualifying Degrees Accepted | Key Focus Area |
|---|---|---|
| PG-DAC (Advanced Computing) | B.E./B.Tech (any branch), MCA, M.Sc. (CS/IT/Electronics/Maths), BCA, B.Sc. (CS/IT) with relevant subjects | Software Development (Java, .NET, Web, Database) |
| PG-DBDA (Big Data Analytics) | B.E./B.Tech (CS/IT/ECE/EEE), MCA, M.Sc. (CS/IT/Maths/Statistics), B.Sc. (CS/IT/Statistics) with maths background | Data Science, Hadoop, Spark, Machine Learning |
| PG-DESD (Embedded Systems Design) | B.E./B.Tech (ECE/EEE/E&TC/CS/IT), M.Sc. (Electronics/Physics) | Embedded C, Microcontrollers, RTOS, IoT |
| PG-DMC (Mobile Computing) | B.E./B.Tech (CS/IT/ECE), MCA, M.Sc. (CS/IT) | Android, iOS, Cross-platform Development |
| PG-DAI (Artificial Intelligence) | B.E./B.Tech (CS/IT/ECE), MCA, M.Sc. (CS/IT/Maths/Statistics) with programming background | AI, Deep Learning, NLP, Computer Vision |
Which Sections of CCAT Do You Attempt?
CCAT has three sections, but not all candidates attempt all three. The sections you're required to take depend on the course you're applying for:
- Section A (Aptitude, English, Reasoning) — Mandatory for all courses
- Section B (C Programming, Data Structures, OOP, OS, Networking) — Required for PG-DAC, PG-DBDA, PG-DMC, PG-DAI
- Section C (Digital Electronics, Computer Architecture, Microprocessors) — Required for PG-DESD
Candidates applying for both software and hardware courses can attempt all three sections. Your rank for each course is calculated based on the relevant sections only. Read our CCAT exam pattern & syllabus guide for a complete breakdown.
Documents Required for CCAT Application & Admission
While eligibility is determined by your degree and marks, you'll need to keep several documents ready for the application process and later during admission:
At the Time of Application
- Scanned photograph (passport size, recent)
- Scanned signature
- Valid email ID and mobile number
- Basic academic details (degree, year of passing, percentage/CGPA)
At the Time of Admission / Counselling
- Degree certificate or provisional degree certificate
- All semester marksheets (consolidated or individual)
- CGPA-to-percentage conversion certificate (if applicable, from your university)
- Category certificate (SC/ST/OBC/PwD, if claiming reservation)
- Photo ID proof (Aadhaar card, PAN card, or passport)
- CCAT scorecard (downloaded from the CDAC website)
- Passport-size photographs (4-6 copies)
- Gap certificate / affidavit (if there's a gap in your education)
Common Eligibility Doubts — Answered
Can I apply with a diploma (polytechnic) degree?
No. A 3-year polytechnic diploma alone is not sufficient. You need a full bachelor's degree (B.E./B.Tech/B.Sc./BCA or equivalent). However, if you completed a diploma followed by a lateral entry B.Tech, your B.Tech degree is valid for CCAT eligibility.
I have a gap year after graduation. Am I still eligible?
Yes, gap years do not affect your CCAT eligibility. There is no restriction on when you graduated. Whether you passed out in 2018 or 2025, you can apply. You may need to submit a gap certificate or affidavit during admission explaining the gap period.
Can I apply from an open/distance university degree?
Degrees from UGC-recognized open universities (like IGNOU) are generally accepted. However, the degree must be in a relevant discipline, and the university must be listed in the UGC's official list of recognized institutions. It's recommended to verify this with CDAC before applying.
I have a B.Sc. in Biology. Can I apply?
CDAC primarily accepts B.Sc. degrees in Computer Science, IT, Electronics, Mathematics, Statistics, and Physics. A B.Sc. in Biology, Chemistry, or other life sciences is generally not eligible for CDAC courses. The qualifying degree must have relevant technical or mathematical subjects.
Can I apply for multiple CDAC courses simultaneously?
Yes. When you register for CCAT, you can indicate your preference for multiple courses. During counselling, you'll be offered seats based on your rank and the courses you're eligible for. You can attempt Section B, Section C, or both — depending on which courses you want to be considered for.
Is work experience required?
No, work experience is not required for any CDAC course. Both freshers and experienced professionals can apply. Your admission is based solely on your CCAT score and qualifying degree.
Tips for a Smooth Application Process
- Verify your eligibility early: Don't wait until the last day to check if your degree is accepted. Visit the official CDAC website and read the eligibility section for each course carefully.
- Keep documents digital: Scan all your marksheets, degree certificate, ID proof, and photographs. Keep them in a dedicated folder for quick access during the application and admission process.
- Get your CGPA converted: If your university uses CGPA, apply for a percentage conversion certificate well in advance. This single document causes the most delays during admission.
- Apply for the right sections: Based on the courses you're targeting, make sure you select the correct CCAT sections during registration. If you want both PG-DAC and PG-DESD, register for all three sections.
- Start preparing immediately: Don't wait for the notification. The syllabus is well-known, and you can begin practicing with free MCQs and mock tests right away.
