## What is Normalization?

Normalization is a term that many government job aspirants must have heard in various examinations. What is Normalization? Staff Selection Commission normalizes the scores of candidates for the tests conducted in multi-shifts to take into account any variation in the difficulty levels of the question papers across different shifts. Normalization means equalizing the scores of candidates who appeared in multiple shifts based on the difficulty level. As SSC exams are conducted over multiple shifts Let’s discuss how the scores are normalized and why is it essential in exams.

### Normalization Formula

SSC uses the normalization formula to calculate the final score of a candidate based on the difficulty of its shift. The formula is based on the average marks scored in a particular shift that determines the difficulty level. The normalization is based on the fundamental assumption that “in all multi-shift examinations, the distribution of abilities of candidates is the same across all the shifts”. This assumption is justified since the number of candidates appearing in multiple shifts in the examinations conducted by the Commission is large and the procedure for allocation of examination shifts to candidates is random. The following formula will be used by the  Commission to calculate the final score of candidates in the multi-shift examinations:

With the introduction of SSC CHSL and CGL normalization, students need not worry if their shift is difficult as compared to others. For example, if the average marks scored by students in the first shift is 120 marks out of 200 and the average marks scored by students in the second shift is 100 marks out of 200 marks, then the marks will be normalized as the second shift was difficult.

### Why is normalization needed?

Normalization in Scores was a unison demand by aspirants as Exam levels in different shifts often seem to be varied. Some aspirants with hard luck fall for the difficult question set in the Exam whereas others get an easy level Question Set comparatively. Therefore, this brings a disparity and causes muddling in the mindset of candidates in final exam merit thus begetting dissatisfaction and impiety in the Commission.
Where several aspirants are already aware of the SSC Normalization process, there seems to be a good number of aspirants for whom normalization in the score is almost a ‘never heard before the term’. Many a time aspirants come out with this question that they happened to appear for the shift in which the question set was of difficult level, either it being Quantitative Aptitude Section where the question might be more lengthy and calculative in some particular shifts or General Awareness Section where candidates might find most of the questions invincible or English Language Section where some shifts might bring out a typical and intricated questions, and in such case are not those candidates at a disadvantage over those candidates who luckily got an easier level Paper Set and thus prone to failure. In such a scenario normalization of marks is the most effective tool to clear any dispute between the difficulty levels of papers. Because it is near to impossible that all Exam Shifts Paper Sets would belong to an identical level and nature of questions.
The organization may add a mark or two to the total score of the candidate if the paper of his shift was very difficult in comparison to other shifts or may deduct a mark or two in the reverse scenario subject to their rules, formula, and guidelines for normalization. The normalization process is based on a formula and based on a few other parameters decided by the authority, the Exam organizing committee derives the formula for calculating the normalized marks for the multi-session papers. For different exam patterns, there is a different formula for the normalization of marks. To bring transparency, win the faith of candidates, maintain the sanctity of the Commission, and conduct a fair competition, Normalization in Score is a remedy.
