How State Board Marking Impacts JEE Main Top 20 Percentile Eligibility

One of the most competitive entrance exams in India is the JEE or the Joint Entrance Examination. Clearing the JEE will help you get into NITs, IIITs and other top colleges. While qualifying JEE Main is essential for admission, meeting the top 20 percentile eligibility criteria based on state board performance plays an equally crucial role for students seeking admission based on the percentile.

Understanding JEE Main Top 20 Percentile Rule

The top 20 percentile eligibility rule was introduced to ensure that high-performing students from all educational boards can get admitted to premier institutes. According to this rule, candidates must either:

• Score at least 75% aggregate marks (for General and OBC categories) or 65% (for SC/ST categories) in their Class 12 board exams

• Or, be among the Top 20 percentile scorers in their respective state or central board.

This means that even if a student’s percentage is slightly below 75%, they can still qualify if they are in the top 20% of scorers from their board.

Impact on JEE Main Top 20 Percentile Eligibility

The percentile cutoff depends on the overall board performance, so the eligibility of an applicant might vary depending on the board they are from.

• Higher Cutoffs in Some Boards

In some boards, a large number of students score above 80 to 90%. Consequently, the marks required to be in the top 20 percentile may rise to as high as 85 to 90%. Students who score below that, even if they have an excellent JEE Main 2026 rank, may fail to meet the eligibility requirement.

• Lower Cutoffs in Strict Boards

On the other hand, in boards with tough marking, fewer students score very high marks. This means the top 20 percentile cutoff could be around 70 to 75%. Students in such boards might qualify for the percentile criterion even with lower scores.

• Advantage to CBSE and ICSE Students

Since a large proportion of JEE aspirants study under CBSE or ICSE, the percentile cutoff of such boards is taken into account. CBSE’s moderate marking pattern often results in a cutoff around 84 to 88%, depending on the year.

Is Top 20 Percentile Required for IIT 2025?

Yes, the Top 20 percentile requirement is necessary for admission to IITs. As per the guidelines set by JoSAA and JEE Advanced, the students must be in the top 20 percentile in their respective Class 12th board exam to be eligible for admission to IIT. This percentile ensures that applicants with the required academic competence can apply for the IITs. Apart from the top 20 percentile requirement, you must also meet the minimum marks in JEE Main to qualify for JEE Advanced. In other words, you must score at least 75% in your Class 12 exams (or be in the top 20 percentile) to be eligible for JEE Advanced.

• For IITs, the top candidates often score 300+ in the exam.

• For NITs, the cut-off typically ranges from 230-250 for General category candidates.

• For IIITs, the mandated score tends to be between 220-250.

State board marking significantly impacts your eligibility for JEE Main top 20 percentile. The marking scheme and competition may vary for different Boards, since each has its own cutoff requirements based on the student’s performance.  Therefore, it is important that you understand the current marking pattern and performance trends of your own state board. This will help you assess your chances of being in the top 20 percentile category, and even if you miss the mark, you can still prepare for alternative pathways beforehand.
