What is IBPS Marks Normalization?
IBPS calculates the marks of all candidates appearing for IBPS Clerk Exam through normalized score calculation. As both the prelims and mains exam is conducted in multiple shifts with varying difficulty levels, Normalization helps in balancing the scores measured on different scales (difficulty shifts ) to a common scale.
Why is IBPS Normalization Done?
IBPS uses the method of Normalization to convert all marks into a standardized format to make it fair for all candidates appearing for the exam. It is done to evaluate the performance of all the candidates on similar exam parameters i.e. it aims to adjust the difficulty level across different shifts of the exam.
- The normalization is done following the fundamental assumption that in all multi-shifts examination, the distribution of abilities of candidates is the same across all shifts.
- This fundamental assumption holds true since the number of candidates appearing in the exam conducted by the Institute of Banking Personnel Selection is large shift allocation is done at random.
How is IBPS Marks Normalization Calculated?
The scores calculated using the normalized formula can be corrected up to 5 places of decimal. Given below is the formula for calculation of final scores of candidates in IBPS exam:
Example for IBPS Marks Normalization
The Normalization of Marks is done in the following manner.
- A candidate got 142 marks on 11 August, 2nd shift.
- The Average marks of top 0.1% candidates in all sessions = 191
- Sum of Mean and SD (cut-off) for all sessions = 131
- Average marks of top 0.1% candidates in 11th August 2nd shift = 185
- Sum of Mean and SD (which is basically a cut-off)for 11th august 2nd session = 129
- Normalization marks = (60/56) (13) + 129 = 142.92
The Note in the Official IBPS notification is as follows: Process of Normalization of Score in IBPS Exams
