JEE Main 2024 Normalization Process: Normalization in JEE Main 2024 is a crucial process aimed at ensuring fairness and equity in assessing the performance of candidates across different shifts or sessions of the examination. As the JEE Main exam is conducted over multiple shifts to accommodate the vast number of candidates, variations in the difficulty level of question papers between different shifts are inevitable. The normalization process is designed to address these variations and ensure that each candidate’s performance is evaluated accurately, regardless of the difficulty level of their specific shift.
The principle underlying the JEE Main normalization process is that the overall ability of a candidate remains constant, irrespective of the difficulty level of the shift they appear in. This principle is essential for creating a level playing field for all candidates, regardless of the specific set of questions they encounter.
Calculation of Percentile Scores
One of the key aspects of the normalization process is the calculation of percentile scores. The National Testing Agency (NTA) calculates percentile scores by considering the number of candidates who scored equal to or less than the candidate in a particular session. This percentile score indicates the candidate’s performance relative to others in the same session.
The use of percentile scores, rather than raw scores, is instrumental in eliminating the impact of variations in question paper difficulty. By comparing each candidate’s performance with that of others in the same session, the percentile scores provide a fair and standardized measure of performance across different shifts.
Importance of Normalization
Normalization plays a crucial role in ensuring that all candidates have an equal opportunity to demonstrate their abilities and compete on a level playing field. Without normalization, candidates appearing in shifts with relatively easier question papers may have an unfair advantage over those appearing in shifts with more challenging papers.
Normalization helps maintain the integrity and credibility of the JEE Main examination by ensuring that the evaluation process is transparent, unbiased, and consistent across all shifts.
JEE Main Normalization Process
The normalization procedure in JEE Main 2024 is a systematic process implemented by the National Testing Agency (NTA) to ensure fairness and equity in evaluating the performance of candidates across different shifts or sessions of the exam. The procedure involves several steps aimed at standardizing the scores obtained by candidates in varying levels of difficulty across different shifts. Here is an overview of the normalization procedure:
- Collection of Data: The NTA collects data from all the shifts of the JEE Main exam, including the question papers, responses of the candidates, and their raw scores.
- Equating Difficulty Levels: The difficulty level of each shift’s question paper is assessed by subject matter experts. Based on this assessment, adjustments are made to equate the difficulty levels across all shifts.
- Calculation of Percentile Scores: The NTA calculates percentile scores for each candidate by comparing their raw scores with those of other candidates in the same session. Percentile scores indicate the percentage of candidates who scored equal to or less than a particular candidate in a specific session.
- Normalization Formula: The normalization formula adjusts the raw scores obtained by candidates based on the difficulty level of their respective shifts. This formula ensures that candidates are not disadvantaged or advantaged due to the variation in difficulty levels.
- Generation of Normalized Scores: Using the normalization formula, the NTA generates normalized scores for each candidate, which accurately reflect their performance relative to other candidates across all shifts.
- Announcement of Results: After completing the normalization process, the NTA announces the results of the JEE Main exam, including the normalized scores and percentile ranks of the candidates.
- Review and Challenge: Candidates have the opportunity to review their normalized scores and challenge any discrepancies or inaccuracies in the calculation within a specified period.
- Finalization of Scores: After addressing any challenges or discrepancies raised by candidates, the NTA finalizes the normalized scores, which are then used for ranking and admissions into various engineering colleges and institutions.
JEE Main 2024 scores for Paper 1 Formula
To calculate the JEE Main 2024 scores for Paper 1, the following formula will be used as part of the normalization procedure:
Formula: Percentile Score = (100 × Number of candidates appeared in the session with raw score equal to or less than the candidate /Total number of candidates appeared in that session)
- The percentile score is calculated by taking the number of candidates who appeared in the same session as the candidate and scored equal to or less than the candidate’s raw score.
- This value is then divided by the total number of candidates who appeared in that session.
- The result is multiplied by 100 to convert it into a percentile score.
Note: To prevent bunching effect and reduce tie-breaking, the JEE Main percentile scores will be calculated up to 7 decimal places. This precision ensures a more accurate and detailed representation of each candidate’s performance relative to others in the same session.
