SSC CGL Normalisation

Normalization in SSC CGL: Government jobs are always the golden goose for those wanting a stable career. SSC CGL, with its varied posts and countless perks, is one of these. This blog is actually going to tackle one aspect of the marking scheme – the normalization process. Let’s take a look at what that is and why it’s in use.

What is Normalization in SSC CGL 2023

SSC conducts a number of exams each year. Due to logistical reasons, it is not always possible to administer the exam in a single session or shift. This is why SSC uses normalization to adjust the scores of candidates who took the exam in different sessions or shifts. This makes scores comparable.

The normalization process takes into account the difficulty level of different sessions or shifts and adjusts the scores accordingly. For example, if one session was more difficult than another, they will adjust the scores of candidates who took the more difficult session upwards to ensure fairness.

SSC may vary the method they use to normalize scores from exam to exam. Also, they may not always make the details of the process public. However, SSC generally provides information about the normalization process in the exam notification or information brochure. So candidates are should carefully read these documents to understand the process.

How Normalization works for SSC CGL 2023

SSC uses a formula to normalize the marks of candidates across shifts based on difficulty level. You can know the difficulty level of a shift based on the overall average of marks that the candidates score. The basic assumption that most exam organizations make for normalization is the same. That is, “in all multi-shift exams, the distribution of abilities of candidates is the same across all the shifts”. Meaning the average ability of the candidates appearing for the exam across all the shifts is the same.

This works because of the large number of candidates who appear in every shift for the exams SSC conducts. Another point in favor is that the process of shift allocation is random.

This is the normalization formula SSC uses:

𝑴_𝒊𝒋 = Normalized marks of the j^th candidate in the i^th shift.
𝑴_𝒕𝒈= is the average mark of the top 0.1% of the candidates considering all shifts.
𝑴𝒒𝒈= is the sum of the mean and standard deviation marks of the candidates in the examination considering all shifts.
𝑴𝒕𝒊= is the average mark of the top 0.1% of the candidates in the ith shift.
𝑴𝒊𝒒= is the sum of mean marks and standard deviation of the ith shift.
𝑴𝒊𝒋= is the actual marks that the j^th candidate obtained in the i^th shift.
𝑴^gm𝒒= is the sum of the mean marks of candidates in the shift having maximum mean and standard deviation of marks of candidates in the examination considering all shifts.

Need for Normalization in SSC CGL

The basic aim of normalization is to compare the performance of the exam takers on an unbiased scale. This way, the result will be free of influencing factors like difficulty level. Normalization makes sure that candidates who face a difficult shift will not be at a disadvantage compared to the ones who got an easier shift. It greatly alleviates tension for students to know they will not suffer because of unbalanced difficulty.

SSC CGL Normalisation – Conclusion

As this blog shows, normalization is an important aspect of mark calculation in SSC exams. While normalization does help increase the scores for difficult shifts, this does not help those who do not prepare. This is why it’s important to do your best and make sure you do not need normalization to help you. In the case of a difficult shift, you will automatically get a boost with the help of this process.

SSC CGL Normalisation – Frequently Asked Questions

What is normalization in exams?

Normalization refers to the process of finding the average marks scored in the shifts of a multi-shift exam and determining the difference in difficulty by comparing these marks. A higher average means an easier shift, while a lower average means a difficult shift. Officials then make sure to adjust the marks to equate the difficulty level.

Is normalization in SSC CGL good or bad?

Normalization is an essential process for SSC CGL. It makes sure no candidate suffers because of unbalanced difficulty compared to other shifts.

When was normalization introduced in SSC CGL?

The process of normalization was introduced in SSC CGL in 2019.

Will SSC CGL Tier-2 2022 have normalization?

SSC CGL 2022 tier-2 will be conducted from 2nd to 7th March 2022. It will be conducted in 2 shifts each day. Hence, normalization will be done for SSC CGL 2022 tier-2.
