A Ph.D. or Doctor of Philosophy in Computer Science and Information Technology is a postgraduate research degree that aims at developing new knowledge in different domains of computer science and IT such as artificial intelligence, big data analysis, software development, computer and information networks, security, etc. The completion of a Ph.D. CSIT program takes around 4 to 6 years for completion with coursework and thesis. During the first years, students are exposed to a range of specialist courses such as algorithms, operating systems, database systems, computer architecture, artificial intelligence, etc in addition to research methods to prepare them for research work.
According to the current trend, the entrance examination that the students are expected to write for enrollment into the Ph.D. CSIT programs in India include UGC NET, GATE, and CSIR NET. Some of the top institutions such as the IITs also have their own aptitude tests as well as interview sessions. The exams are usually conducted between May and July for most courses every year. The opening dates for applications normally close early March for full-time Ph.D. programs for students joining in July while for part time and external registration, the opportunities may exist throughout the year depending on the institutes. Some of the institutes may have different timelines and application requirements and candidates should visit the websites of institutes of their choice to confirm the same. In many of the organizations, shortlisted candidates undergo an interview process before the final appointments are made.

Course Level
Doctoral
Eligibility
Master's degree in Computer Science, Information Technology, or a closely related field with a strong foundation in computer science fundamentals and mathematics.
Top Colleges (India)
* Indian Institutes of Technology (IITs) * Indian Institute of Science (Bangalore) * National Institute of Information Technology (NITs) * Indian Institute of Information Technology and Management (IIITM) * Indian Statistical Institute (ISI)
1. Candidates who have passed Master of Computer Science/Information Technology or any other equivalent degree with at least 55% marks or equivalent CGPA are eligible to apply.
2. Besides, CLEAR, other tests that qualify an entrance exam include GATE, UGC-NET, and those offered by the university or institute. Few of the institutes provide direct admission solely on the basis of master’s degree results.
3. Applicants selected for the second stage are required to sit for an interview session to defend their proposed research topics. The admissions are based on the academic achievements and entrance test scores, in addition to an interview.
4. Some institutes require work experience in the field of computer science/IT although some do not consider it essential.
5. It is thereby required that participants have some level of programming knowledge and skills in the area of the research. An added advantage would be if the candidates have published papers.
