Commonly asked questions

Q: Is NIELIT CCC more advanced than O-level?

No, NIELIT O-level is slightly more advanced than CCC. It is a one-year Diploma course that provides education in Computer Science and Engineering. It is nearly equivalent to a Polytechnic Diploma and is slightly tougher. In this course, students learn about programming, multimedia, ICT, etc. NIELIT CCC is a certificate course, where only a basic computer knowledge test is conducted, which consists of details about hardware, software, number systems, spreadsheets, word processors, etc.

Q: How many levels are there in NIELIT?

NIELIT offers admission to the courses at various levels, including

'O': Foundation Level
'A': Advanced Diploma
'B': MCA Equivalent
'C': M.Tech Level in Computer Science and Engineering
Digital Literacy Courses

- ACC (Awareness in Computer Concepts)
- BCC (Basic Computer Course)
- CCC (Course on Computer Concept)
- CCC+ (Course on Computer Concept Plus)
- ECC (Expert Computer Course)

Q: Is there an entrance exam for NIELIT?

Yes, there is an entrance exam for NIELIT. The exam of NIELIT is taken for admission to different undergraduate and postgraduate courses, including:

Non-Formal Courses - 'O' Level (Foundation), 'A' Level (Advance Diploma), 'B' Level (MCA equivalent), 'C' Level (M-Tech level)
IT literacy courses: CCC (Course on Computer Concept), BCC (Basic Computer Course) and similar long-term and short-term courses.

The NIELIT exam is conducted twice a year, in January and July.

Q: What is the medium for the NIELIT exam?

There is a facility for candidates to choose to write the answers (the descriptive part only) either in English or Hindi. The preference should be marked therein.
