In the pursuit of fostering a level playing field for aspiring engineers across the nation, the National Testing Agency (NTA) employs a sophisticated ‘Normalization Procedure based on Percentile Score’ for evaluating JEE Main performances. This meticulous process is designed to nullify the impact of varying difficulty levels among different sets of examination papers, ensuring that no candidate is unfairly advantaged or disadvantaged.
The official communication from the JEE Main website underscores the need for this normalization procedure, especially when the exam is conducted on multiple dates with different sets of questions per session. Despite rigorous efforts to maintain equivalence, the inherent challenge lies in the potential variation in difficulty levels among these question papers. Some candidates may contend with a more formidable set of questions, impacting their scores relative to those who face a comparatively easier set. To address this, the ‘Normalization Procedure based on Percentile Score‘ comes into play.
Percentile scores, a pivotal component of this process, gauge a candidate’s performance relative to others. These scores are transformed into a standardized scale ranging from 0 to 100 for each session of examinees. The Percentile Score of a candidate is calculated by comparing the number of candidates in a session with a raw score equal to or less than the candidate against the total number of candidates in that session.
Let’s delve into the steps of this normalization procedure:
Step 1: Session Distribution. Candidates are randomly distributed into two sessions, ensuring an equitable distribution of candidates in each session. This step becomes crucial, particularly when the exam is held on a single day. If the exam spans multiple days or has fewer shifts, candidates are divided accordingly.
Step 2: Raw and Percentile Scores. Raw scores and percentile scores for each session are meticulously prepared. The Percentiles are calculated for each candidate in a session, providing a benchmark against the performance of their peers in that particular session.
Step 3: Merging Percentile Scores. The Percentile scores for the total raw scores across all sessions are amalgamated, giving birth to the NTA scores. These NTA scores serve as the cornerstone for result compilation and subsequent processes to determine the final allocation.
Closing Thoughts
In essence, the normalization procedure stands as a guardian against the inherent challenges posed by varied question paper difficulty levels. It not only ensures fairness but also upholds the integrity of the evaluation process in the highly competitive realm of JEE Main. This meticulous approach, based on Percentile Scores, stands as a testament to the commitment of the NTA in providing a fair and unbiased assessment platform for all JEE Main candidates.
