CAT Normalization Process 2023: How Scaled Score is Calculated, Revised Process for 3 Shifts

The CAT normalization process 2023 is adopted to ensure that all the test-takers are evaluated on the same ground and no one is given undue advantage or at a disadvantage in the exam. Also known as the scaling and equating process, the CAT normalization process shall adjust for location and scale differences of score distributions across different forms.

The CAT normalization process consists of two steps. In the first step, the IIMs adjust the exam scores to account for differences in the distribution of CAT scores across different forms. In the second step, the scores of different sections are normalized. The CAT result includes detailed information on both the sectional and overall scaled scores. The CAT exam for 2023 was conducted on November 26, 2023, across the nation in three different slots by IIM Lucknow, and the CAT result was released on December 21, 2023. Find below the complete details about the CAT normalization process 2023.

CAT Normalization Process 2023: How It Is Conducted?

The CAT Normalization Process is carried out in two steps.

1. In the first step of the CAT normalization process, IIMs adjust the exam scores for 'scale differences of score distribution across different question papers'.

2. In the second step, after the normalization process has been applied across different question papers, the scores across different sections are normalized.

After a candidate has attempted the CAT question paper, their 'Raw Scores' are calculated which are based purely on the number of correct answers and the number of wrong answers in the CAT exam. To calculate the raw score, a candidate must know the:

• CAT Marking Scheme (+3, -1)

• No. of Correct Answers

• No. of Incorrect Answers

Raw Scores in CAT can be calculated by using the following formula.

Once the raw scores have been calculated, the CAT normalization process can be applied to get the Scaled Score of a candidate in CAT. The CAT scorecard which is released with the declaration of CAT Results contains the scaled scores of a candidate. The CAT percentile, whether it be overall or section-wise, is also calculated using the CAT scaled scores.

Importance of Normalization in CAT 2023

Candidates appearing in different shifts get different question papers for CAT. Even though the conducting body i.e. IIMs ensures that the question papers are identical in their difficulty level, there may be some discrepancies in the difficulty level of question papers or test forms.

Hence, a probability arises that candidates of one slot may get an easier question paper than candidates of the other slot. To nullify this advantage, IIMs employ the CAT Normalization process. It is the adjustment done in the CAT score of participants to ensure that there is no discrimination for or against any candidate in the calculation of final CAT scores. The normalized CAT result is a very important factor in the overall CAT selection process 2023 as well.

What is the Scaled Score in CAT?

The CAT exam is conducted in multiple sessions (two or three). Since the question paper for each session is slightly different from one another, a scaled score is produced through the CAT normalization process to ensure fairness and equality in the performance comparison of all candidates. This scaled score could vary in different ways from the raw score.

Revised CAT Scaled Score Calculation

Since CAT 2023 is being conducted in 3 shifts, the following information has been updated to account for the same.

The scaled score of CAT is calculated across each section of the exam. Once the scaled score of each section has been calculated, the overall score can be calculated by simply adding up the scaled scores of each section.

In order to easily understand the process of normalization of CAT scores, it is better to break down the process into multiple steps and understand each variable that is used in the formula. Let's first understand the steps to calculate CAT scaled score and then we will take a look at the formula.

These steps are applied section-wise i.e. raw scores of only one section are considered at a time when calculating scaled scores.

Step 1: Mean (Average) and Standard Deviation (SD) of the raw scores of candidates who appeared in the 1st shift are calculated and added together.

Step 2: Mean and SD of the raw scores of candidates who appeared in the 2nd shift are calculated and added together.

Step 3: Mean and SD of the raw scores of candidates who appeared in the 3rd shift are calculated and added together.

Step 4: Mean and SD of the raw scores of all of the candidates who appeared across all three of the sections are calculated.

Step 5: Mean of the raw scores of the top 0.1% of the candidates who appeared in the 1st shift is calculated.

Step 6: Mean of the raw scores of the top 0.1% of the candidates who appeared in the 2nd shift is calculated.

Step 7: Mean of the raw scores of the top 0.1% of candidates from the 3rd shift is calculated.

Step 8: Mean of the raw scores of the top 0.1% of the candidates across both sections is calculated.

Step 9: The following formula is used to calculate the scaled score of a candidate. Please note that the given formula is for a candidate who appeared for the 1st shift.

The relevant values in this formula must be changed accordingly to calculate the scaled score of a candidate in the other two shifts.

Here, R is the Raw Score of the candidate whose scaled score is being calculated.

CAT Composite Score: How IIMs Calculate It?

The CAT composite score is an essential factor in evaluating a candidate's overall profile for admission into MBA programs offered by the IIMs. While the CAT score is significant, the composite score considers other factors such as academic background, work experience, extracurricular activities, and diversity. It's worth noting that candidates with similar CAT scores may still have different composite scores due to differences in these parameters. The composite score provides a comprehensive assessment of a candidate's potential for admission into IIMs. Below are the parameters considered when calculating the CAT composite score:

• Class 10th Marks

• Class 12th Marks

• Graduation Percentage/ Grade

• Work Experience

• Academic Background

• Gender Diversity

How Is the CAT Composite Score Calculated?

The CAT composite score is calculated by IIMs using the following formula:

How Is CAT Percentile Calculated?

A CAT percentile shows what percentage of candidates have received a lesser score than you in the CAT exam. In order to calculate the CAT percentile, it is important to know two things:

1. Your rank in CAT (R)

2. Total no. of candidates who appeared for CAT (N)

The steps outlined below are used to compute a candidate's CAT 2023 overall and sectional percentile scores. The QA section is used as an example to demonstrate the percentile score calculating method.

Step 1: The total number of appearing candidates(N) for CAT is taken into account. It includes the morning, afternoon, and evening sessions). 

Step 2: A rank (r) is assigned to all the candidates who appeared for CAT 2023, depending on the computed scores obtained in the QA section. In a scenario where two/more candidates have obtained identical scaled scores in the QA section, identical ranks are assigned to all such candidates. For instance, let's suppose that exactly two candidates have obtained the highest scaled score in the QA section. In this case, both candidates are allocated a rank of 1. Furthermore, the candidate(s) securing the second-highest scaled score in the QA segment is assigned a rank of 3, and so on.

Step 3: The candidate's percentile score (P) is calculated with rank (r) in the QA section like this:

Step 4: The candidate's estimated percentile score (P) should then be rounded off to the nearest two decimal places.
