Performance Criteria in Class XII (or equivalent examination)
- Candidates whose Class XII (or equivalent) examination results have not yet been declared can apply for IAT 2025. However, their admission will be subject to fulfilling the minimum eligibility criteria given above.
- For candidates who have appeared in the Class XII (or equivalent) examination multiple times (for whatever reasons), the best of the performances in terms of aggregate in a given year will be considered.
- If a board gives aggregate marks considering both Class XI and Class XII, then only Class XII (or equivalent) examination marks will be considered. If a board gives aggregate marks considering the results of all three years of a 3-year diploma or courses of equivalent duration, then only the marks scored in the final year will be considered. Similarly, the marks scored in the final two semesters will be considered for boards that follow a semester system.
