What Are IITs?
Indian Institutes of Technology, also known as IITs, are well-known centres of higher education in India that have been renowned in the fields of engineering, technology, science and research.
They have courses like BTech, MTech, MSc, MBA and PhD in various disciplines. IITs are believed to possess good academic courses, faculty, research and a good admission process.
Interested students who have the desire to be enrolled in undergraduate engineering programmes usually need to qualify in JEE Main and JEE Advanced. Another benefit offered by IITs is that students have been able to acquire skills in technical, problem-solving , and research.
What is IIT Admission Criteria?
The admission requirements of IIT, BTech as well as other undergraduate programmes include the requirements of JEE Main, JEE Advanced, Class 12 subjects and marks, age and attempts.
The rules might not be the same as that of the dot, i.e. year of admission; a candidate will be recommended to refer to the official information brochure of JEE Advanced to get the year.
1. Entrance Exams
IIT BTech programmes are based on admission by JEE Advanced. The students need to successfully clear JEE Main Paper 1 (BE/BTech) to be allowed to take JEE Advanced, and satisfy JEE Main requirements.
The exam may be taken by the applicants based on the eligibility criteria of JEE Advanced. Based on the rank, category, preferences and availability of seats, JEE Advanced, post-selection, assigns seats based on the Joint Seat Allocation Authority (JoSAA).
2. Academic Qualification – Class 12 Requirement
To qualify for B Tech, students must have completed Class 12/equivalent examination and the following are mandatory: Physics, Chemistry and Mathematics (PCM).
In case of in-service students and those in other classes who will be in Class 12 in the current year of admission, they can also apply on the condition that the requirements are fulfilled as stated in the JEE Advanced information brochure.
This may also take several years to be imparted to individuals who already pass Class 12 next year.
3. Class 12 Marks Requirement for IIT Admission
Have a combined mark of 75% in Class 12 or equivalent examination . In most instances, the 65% aggregate marks are the minimum requirement in case of SC, ST and PwD candidates.
The mark requirements are subject to the regulations of the year of admission at that time, and the students must make sure to check the relevant brochure before doing so.
4. Minimum Marks
The 75/65% cannot be compared with the lowest score in the JEE Advanced. The candidates will also have to possess the required marks in the JEE Advanced in order to feature in the rank list.
JEE Advanced has subject-level and aggregate-level qualifying marks and is announced on the date of each examination.
It is not a guarantee to get into IIT once Class 12 qualification is attained. It also requires JEE Advanced rank, category, programme preferences and availability of seats to be able to get admission.
5. Age Limit
In JEE Advanced, applicants must fulfil the date-of-birth requirement as stated in the year of the test. The rules of the JEE Advanced 2026 include one, comprising a set of cutoff dates based on birth date.
As the age requirement changes every year, the applicants should refer to the joint information brochure of JEE Advanced and not be misdirected by a fixed age requirement of a past year.
6. Number of Attempts
A candidate was allowed to attend JEE Advanced in two sittings of two consecutive years as a rule. The attempt rule is determined based on the qualification of the candidate and his/her performance in JEE Advanced.
Students are also to keep in mind the rules of attempts and eligibility of JEE Main and JEE Advanced.
That is why it will not allow the candidates to ignore the right provisions of the year in which they plan to take their exam attempts.
IIT Eligibility Percentage
IIT BTech admission typically demands performance in Class 12 of JEE Advanced for applicants.
They should be able to obtain not less than 75% of aggregate marks in Class 12, or they should be in the 20th percentile of the successful candidates in their respective boards. The lowest overall in cases of SC, ST and PwD would be 65%.
JEE Main Eligibility Criteria
The students who appear in the JEE Main Paper 1 (BE/BTech) should have passed Class 12 or an equivalent examination or should be taking the qualifying examination in the years allowed.
In the case of BTech, the mandatory ones are Physics and Mathematics and either Chemistry, Biology, Biotechnology or a vocation of a technical nature.
There is no age limit on taking JEE Main, although certain institutions may have their own age limit regarding their admissions.
JEE Advanced Eligibility Criteria
In order to feature in JEE Advanced, he/she must have passed JEE Main and be ranked among the 2,50,000 successful candidates in category-wise distributions in the first paper of the JEE Main.
The candidates also need to be in conformity with the provisions of Class 12, age limit, number of attempts and other provisions in that year.
To enrol in IIT, one has to pass JEE Advanced, which does not ensure admission. JoSAA counselling will involve ranking and categorising the candidate, and subsequently he may be admitted to the school of the programme of his choice on the available seats.
IIT Admission Criteria for Different Categories
All candidates undergo the basic IIT admission process, though there are category-based principles which determine the reservation, qualifying marks, rank lists and seat allotment.
In the case of JEE Advanced 2026, the types of basic reservations are GEN, GEN-EWS, OBC-NCL, SC, and ST. It is also the category which defines the minimum marks needed to be listed in the JEE Advanced rank list.
The total qualifying requirement in 2026 is 25.56% for the Common Rank List, 22.78% for OBC-NCL and GEN-EWS and 12.78% for SC and ST. These are the percentages of JEE Advanced 2026, and these may vary on an annual basis.
| Category | Qualifying Requirement |
| Common Rank List (GEN) | 25.56% |
| OBC-NCL and GEN-EWS | 22.78% |
| SC/ST | 12.78% |
IIT Admission Criteria: Step-by-step Process
The IIT admission is conducted in a series of events such as eligibility information, attendance at the entrance test, counselling, seat allotment, verifying documents and finally, admission.

JoSAA Counselling Process
The centralised process of allotment of seats to be taken in IITs, NITs, IIITs and other participating institutes is the JoSAA counselling process.
Those who have successfully applied in JEE Advanced and JEE Main will be required to undergo next-step registration, fill in their preferred courses and institutions and undergo a set of seat allocations.
Allotment of seats depends on rank, category, choice preferences, as well as availability of seats.
Step 1: Register for JoSAA
The deserving candidates are registered in the official JoSAA portal using their JEE qualifications. They are supposed to submit their required information and complete registration within the required time.
Step 2: Fill and Lock Choices
The candidates select the course of their choice and the institutes and prioritise them. When satisfied, they are able to lock their choices within the time.
Step 3: Seat Allocation
JoSAA conducts a series of counselling rounds and assigns seats based on rank, category, preference of choice and availability.
Step 4: Accept the Allotted Seat
Those who are offered a seat are allowed to choose the appropriate one-Freeze, Float or Slide (where applicable)-and pay the required seat-acceptance fee.
Step 5: Document Verification
The candidates post the necessary documents to be verified over the Internet. They may have to carry along Class 10 and 12 certificates, category certificates, identity proof and other documents which are mandatory.
Step 6: Final Seat Confirmation
Once the formalities are successfully completed and confirmed, the successful applicants affirm their acceptance and report to take part in the allotted institute as per instructions.
Documents Required for IIT Admission
Candidates are required to submit documents that they need before they are subjected to JoSAA counselling.
The requirements can vary according to category and year of admission. Documents for JoSAA counselling, seat acceptance, document verification and final admission are:

5 Common Mistakes Students Make during IIT Admission
Students can sail through the whole process and therefore have a better chance of acquiring their course and institute of choice when the pitfalls that could arise in accepting students to IIT are avoided.
1. Not Checking Eligibility Criteria Properly
Students must ensure that they have the latest eligibility criteria and that they have fulfilled them fully prior to the application.
The subjects, importance of marks, age, entrance exam, and other provisions have to be verified; otherwise, the subject will not be in a position to receive admission and enrol.
2. Missing Important Deadlines
JEE applications, examinations, counselling, choice filling, paying of fees and document verification are some of the major IIT admission dates.
Candidates can miss the opportunity to take an exam or even take a seat due to a missed deadline.
3. Incorrect Category Selection
This is to be filled in the application and counselling forms, and a student must select their category correctly.
They should have a copy of authentic documents to prove their classification as well. False information or certificates may also cancel the admission reservation benefits during the admission process.
4. Poor Choice Filling in JoSAA
Students are suggested to make IIT and course choices as per their interests, rank, and preferences. The lack of proper planning in the filling may result in an undesirable path or institute in the process of assigning seats.
5. Ignoring Mock Counselling
The simulated counselling will assist the students to gain a bit of information about the JoSAA filling, choice-allocation, and seat-allocation process. The results will enable the students to check their preferences, choose better and eliminate errors prior to the actual counselling rounds.
5 Alternative Routes if You Don’t Get IIT
Rejection by an IIT does not mean you end your engineering possibilities. Through JEE Main or state entrance examinations, or admission procedures that take place at the university level, students will be able to join other good institutes.
1. NITs (via JEE Main)
Nationally funded technical institutions that offer BTech programmes in computer science, mechanical, electrical, civil and electronics engineering amongst others are known as National Institutes of Technology (NITs).
Entry to NITs largely depends on performance in JEE Main, after which there is JoSAA counselling. Based on their rank, category and the number of seats, students are allowed to choose their desired NIT and branch.
NIT Trichy, NIT Rourkela, NIT Surathkal, NIT Warangal, NIT Calicut and NIT Allahabad are some of the popular NITs.
2. GFTIs
Government-Funded Technical Institutions (GFTIs) are a number of government-backed institutions that provide engineering and technology programmes.
Many participating institutes take admission either through JEE Main and JoSAA counselling, but the requirements may vary according to the institute.
Famous institutions include Assam University, Tezpur University, University of Hyderabad, Pondicherry University, Harcourt Butler Technical University and Sant Longowal Institute of Engineering and Technology.
3. State Engineering Colleges
State engineering colleges also offer another alternative that could be given to students who fail to acquire an IIT seat. This may be through admission based on JEE Main, state-level entrance tests or state counselling, depending on the state and the institution.
Others that are famous are Jadavpur University, Delhi Technological University (DTU), Netaji Subhas University of Technology (NSUT), College of Engineering Pune (COEP Technological University) and Anna University.
4. Private Universities
The majority of the popular majors of computer science, artificial intelligence, electronics, mechanical engineering and biotechnology are provided at privately operated universities as BTech.
Admission can be done on the basis of JEE Main scores, a university entrance exam, on a merit basis or any other process as specified by the university.
Popular choices include VIT Vellore, BITS Pilani, Manipal Institute of Technology, SRM Institute of Science and Technology and Shiv Nadar University.
Conclusion
The IIT admission entails a set of both academic and entrance exam qualifications for students before undergoing counselling and allotment of seats. It is done based on the JEE Main, the JEE Advanced, Class 12 marks, category, rank and choice of course.
To prevent mistakes and gain better chances to get admission, students are to monitor the recent eligibility regulations, gather necessary documents, observe significant deadlines, and make wise decisions at JoSAA counselling.
