The bill, was passed, aiming to generate highly competent manpower of global standards for the Information Technology Industry, expected to act as a major catalyst to develop new knowledge in the field of Information Technology.^[5]

The admission to IIIT is through Joint Seat Allocation Authority (JOSAA) and Central Seat allocation Board (CSAB). The students are allotted admission by JOSAA based on their Joint Entrance Examination (JEE-Main) ranks.^{[citation needed]}

The Institute presently offers B.Tech in Computer Science and Engineering (CSE) and Information Technology (IT) with an intake of 120 and 60 students respectively.^{[citation needed]}

IIIT Sonepat campus is under constructions. The initial classes were running in the premises and under the mentorship of National Institute of Technology, Kurukshetra till 2018 , after which the classes were shifted to Rajiv Gandhi Education City in the secondary campus of Indian Institute of Technology Delhi.^{[citation needed]}

In a major development in the field of education, the Indian Institute of Information Technology, Sonepat (IIIT Sonepat) has announced its campus shift to the SBIT (Sonepat-Bahalgarh Industrial Area) in the year 2022. Currently, the 1st, 2nd, and 3rd-year students are studying at the new transit campus, while the 4th-year students are still studying at the IIT Delhi Technopark Campus.

The administration has taken a commendable step by allocating hostels to the 1st year students on the SBIT campus. This will enable them to have easy access to the facilities and amenities available on the campus, and create a sense of community among the students.

For the 2nd and 3rd-year students, the administration has arranged for accommodation at the Stanford International School, which is managed by CoHo. The school is located 1.6 km from the SBIT campus, and buses have been arranged to transport the students to and from the campus. The accommodation provided by CoHo is known for its modern facilities and comfortable living spaces, ensuring that the students have a comfortable stay during their studies.

The girls are currently residing at the IIT Delhi Technopark campus along with the 4th-year students. The IIIT Sonepat administration has made arrangements to ensure the safety and security of the girls while they are residing on the Technopark campus.
