IIST Admission and Exam Results 2026: Core Details

For any student associated with the prestigious IIST, understanding the key details about the result process is crucial. The institute manages separate systems for admission results and internal academic results. Here is a summary of the essential information.

How to Access Your IIST Rank List and Admission Status

The process to check the IIST admission result is centralized through its dedicated portal. Unlike state universities that may have multiple links for different courses, IIST provides a single login-based system. Follow these steps carefully to view your rank and status.

1. Navigate to the Official Portal: Open your web browser and go to the official IIST admissions website: admission.iist.ac.in/. Avoid using third-party websites.
2. Locate the Result Link: On the homepage, look for the specific notification related to your programme, such as “B.Tech Admission 2026 Rank List Published” or “M.Tech Interview Results”. Click on the relevant link.
3. Enter Login Credentials: You will be directed to a login page. Here, you must enter your Application Number, Registration Number, or other required credentials along with your password. You may also need to solve a captcha.
4. View Your Result: After successful login, your admission status, rank, and other details will be displayed on the screen.
5. Download for Future Reference: It is highly recommended to download a copy of your rank card or admission status page as a PDF. Take a printout for your records and for the counselling process.

Note: On result declaration day, the server might experience heavy traffic. If the website is slow or unresponsive, please wait for some time and try again.

IIST B.Tech Admission Cutoff Ranks (Reference)

To provide aspirants with an idea of the competitive standards for admission, IIST publishes statistics from previous years. The following table shows the opening and closing ranks for the 2025 undergraduate admissions, which can serve as a valuable reference for 2026 candidates.

Note: The ranks mentioned above are based on the IIST Admission Rank List, which is prepared from applicants who have qualified JEE (Advanced). These cutoffs are subject to change each year based on the number of applicants and their performance.

IIST Semester, Revaluation, and Arrear Results

For current students, IIST conducts end-semester examinations twice a year. The results, along with options for revaluation and procedures for clearing backlogs, are managed by the academic office.

How to Check Semester Exam Results

Results for regular end-semester examinations are not published on the public admissions portal. They are made available through the internal student portal (such as Aditya Webmail or the academic ERP system). Students can log in with their credentials to view their detailed grade sheets, which include Subject-wise Grades, Semester Grade Point Average (SGPA), and Cumulative Grade Point Average (CGPA).

IIST Grading System Explained

IIST follows a 10-point relative grading system. The performance of a student is evaluated in terms of two indices: the Semester Grade Point Average (SGPA) and the Cumulative Grade Point Average (CGPA).

• SGPA: It is the weighted average of the grade points obtained in all the courses registered by a student in a semester.
• CGPA: It is the weighted average of the grade points obtained in all the courses registered by a student since the beginning of their programme.

The letter grades and their corresponding grade points are as follows:

Revaluation and Scrutiny of Answer Scripts

Students who are not satisfied with their grades can apply for revaluation or scrutiny of their answer scripts. The process is time-bound and must be followed carefully:

1. Notification: The academic office releases a notification with deadlines for revaluation applications, typically within a week of the result declaration. This is published on the official website or internal portals.
2. Application: Students must fill out the prescribed application form, clearly mentioning the subjects they wish to have re-evaluated.
3. Fee Payment: A non-refundable fee per subject must be paid through the designated mode. The exact fee amount will be specified in the official notification.
4. Submission: The completed form and fee receipt must be submitted to the academic office before the last date.
5. Result: The revaluation results are typically declared within 3-4 weeks. The final grade may increase, decrease, or remain the same. The revaluation result is considered final.

Clearing Arrear/Backlog Examinations

Students who fail to secure passing grades (an ‘F’ grade) in one or more subjects are required to appear for arrear (backlog) examinations. The procedure is as follows:

• Registration: Before the start of each semester’s exams, the institute opens a registration window for students to apply for their pending backlog papers.
• Exam Schedule: The arrear exams are usually conducted along with the regular end-semester examinations.
• Fee: A separate examination fee must be paid for each backlog paper the student registers for.
• Result Declaration: The results for arrear exams are declared along with the regular semester results of that examination session. The dates are indicated in the main result table at the top of this article.

The IIST Admission Process: From Entrance Test to Final Rank List

Understanding how IIST results are formulated is key for aspirants. The process is rigorous and directly linked to performance in national-level entrance tests.

For Undergraduate (B.Tech & Dual Degree) Admissions

Admission to IIST’s B.Tech programmes relies entirely on the performance in the Joint Entrance Examination (JEE) Advanced.

• Candidates must qualify JEE (Main) and then appear for JEE (Advanced).
• After the JEE (Advanced) results are declared, eligible candidates must apply separately to IIST through its admission portal.
• IIST then prepares its own merit-based Admission Rank List from the pool of applicants based on their JEE (Advanced) scores and category ranks. This rank list is the primary “result” that determines who gets called for counselling.

For Postgraduate (M.Tech/Master of Science) Admissions

For PG courses, admission is based on scores from national tests like GATE, JEST, or UGC-NET, followed by an interview or a written test. The final result is a list of selected candidates based on their performance in both stages.

Information Present on the IIST Admission Result/Rank List

When you access your IIST admission result, you should carefully verify all the details mentioned. A typical IIST rank list or admission status page will contain:

• Candidate’s Name and Application Number
• JEE (Advanced) Roll Number (for B.Tech applicants)
• Category (General, EWS, OBC-NCL, SC, ST)
• All India Rank (JEE Advanced)
• IIST Admission Rank (Category-wise)
• Admission Status: Shortlisted for counselling, Waitlisted, or Not Selected.
• Counselling Schedule and further instructions.

Post-Result Formalities and Seat Allotment

The declaration of the rank list is just the first step. Selected candidates must complete several post-result formalities to secure their admission. The process generally involves:

1. Acceptance of Offer: Candidates allotted a seat must formally accept it through the portal within a stipulated timeframe.
2. Payment of Fees: The first semester fees and any applicable seat acceptance fees must be paid online.
3. Document Verification: Candidates must upload scanned copies of original documents for online verification, including 10th and 12th mark sheets, category certificates, ID proof, and JEE/GATE scorecards.
4. Physical Reporting: Finally, students must report to the IIST campus in Thiruvananthapuram on a specified date for physical verification and completion of admission formalities.

Candidates should regularly check the IIST admission portal for updates. As a related note for current and graduating students, the 14th IIST Convocation is scheduled to be held on July 30, 2026.
