CSIR NET Normalisation of Marks 2024: Percentile Calculator & Result Preparation

CSIR NET result 2024 has been declared by the NTA for the December session on the official website on the basis of the CSIR NET normalisation of scores. The CSIR NET 2024 Dec session exam was conducted from February 28 to March 2, 2025. The cut off will be announced soon. Check below for the complete process of the CSIR NET percentile calculator, normalisation of marks and CSIR NET result preparation.

CSIR NET 2024 Normalisation of Marks & Percentile Calculator

CSIR NET Dec Result 2024 has been announced by the National Testing Agency (NTA) on its official website at csirnet.nta.ac.in. Candidates can check their results through the official website. A direct link is also provided below.The CSIR UGC NET result 2024 has been declared through the normalisation of scores. The CSIR NET percentile is calculated through the NTA Score. The authority will soon release the CSIR NET 2024 cut off.

The CSIR NET Dec 2024 session exam was conducted on February 28, March 1 and March 2, 2025. The exam was held in shifts for five papers- Earth Sciences, Physical Sciences, Mathematical Sciences, Chemical Sciences and Life Sciences. In each session, candidates will be given different sets of CSIR NET question papers.

Though the NTA undertook all the necessary efforts to maintain the same difficulty level for all the sets of question papers, it might be possible that some candidates could have ended up attempting a tougher set of CSIR UGC NET questions for a particular paper. Such a situation could end up lowering the CSIR NET scores of candidates.

To resolve this problem and ensure fair evaluation of candidates’ performance, NTA uses the Normalisation procedure based on Percentile Score.

CSIR NET Normalisation Process

The normalisation process is an established practice to compare the scores of candidates across multiple shifts of the CSIR NET exam. To normalise the CSIR NET scores across all the sessions, NTA uses the percentile score calculation method.

What is CSIR NET Percentile Calculator?

Percentile scores are the scores based on the relative performance of all candidates who appear for the CSIR NET examination. Basically, the marks obtained by candidates in various shifts are transformed into a scale ranging from 100 to 0 for each session.

The percentile score calculation indicates the percentage of candidates that have scored either equal to or below that particular percentile in the examination. Therefore, the topper with the highest score of each shift of CSIR UGC NET will get the same percentile of 100. The marks obtained between the highest and lowest scores are also converted to appropriate percentiles.

The CSIR NET percentile calculator will be used to normalise the scores (instead of the raw marks of the candidate). The CSIR NET normalisation of marks is also used for the preparation of the merit lists.

The CSIR NET percentile scores are calculated up to 7 decimal places to avoid ties among the candidates.

How To Convert Percentile into Percentage?

Check below the method to convert the score for CSIR NET 2024 from the percentile into a percentage. 

CSIR NET 2024 Percentage = Raw Score in the Exam x 100/120

Here, candidates need to make sure that there is no direct formula to convert the scores from a percentage into a percentile or vice versa, so it is necessary to use the raw score while calculating. This is explained in detail below.

How to Calculate the CSIR NET Percentile Score?

The NTA uses the following formula to calculate the CSIR NET percentile scores of candidates:

Have a look at the following example to calculate the percentile score:

Suppose CSIR NET was conducted in four sessions. The distribution of candidates in the four sessions was as follows:

The highest raw score in each paper will be the 100 percentile indicating that 100 per cent of candidates have scored equal to lesser than the highest scorer of that session.

Highest raw and percentile score: All the highest raw scores have a normalised percentile score of 100.

Lowest raw and percentile score: The percentile score of the lowest raw scores depends on the total number of candidates who gave the exam for their respective sessions.

CSIR NET Result Preparation with Normalisation of Scores

The CSIR NET result is prepared with the normalisation of marks of candidates as per the given steps:

Step 1: Distribution of candidates in two shifts

Firstly, the total number of candidates who appeared for the exam is distributed in two sessions so that each session has an equal number of candidates. The two sessions are as follows:

Session-1: Day-1 Shift-1, Session-2: Day-1 Shift-2

Note: If the exam is held in a more number of days or less number of shifts, the candidates will be divided accordingly.

Step 2: Result preparation for each session

The CSIR NET result is prepared for each session in the form of:

• Raw scores
• Percentile scores of total raw scores

The percentile score of each candidate in a particular session is calculated as per the given formula:

Step 3: Compilation of CSIR NET scores

The percentile scores of the total raw scores for all the sessions, calculated in Step 2, are merged to form the NTA scores (percentile). These NTA scores are then used by the NTA for the compilation of CSIR UGC NET results.
