HSSC Normalization: Haryana Staff Selection Commission has released the public notice regarding the normalization method followed by the HSSC during the marking of the candidate’s scores. Haryana Staff Selection Commission conducts written examinations for the purpose of recruitment to some Group B posts and all Group C and D posts in the Haryana Government. The reason behind the normalization of marking the exams are conducted in multiple shifts is because of a large number of candidates appearing for the same and due to the difficulty in getting adequate number of examination centers for the conduct of the examination in one shift. The examination papers in different shifts are at times of different difficulty levels and also at times set by different examiners.
To overcome this issue Haryana Staff Selection Commission has decided to normalize the scores of candidates for the examinations which are conducted in multi-shifts.On the advice of the Indian Statistical Institute, Delhi,
a normalization procedure based on the percentile method will be adopted by the Commission to calculate the final marks of candidates in multi-shift examinations. Candidates can download the official notification PDF from the link provided below.
The normalized score of any candidate is defined as the percentile of the candidate in the shift. This is the same as the percentage of candidates from the same shift who have scored less than or equal to the marks scored by the candidate. In such a case, the person who scores the maximum marks in any shift will get the maximum percentile score of 100 which is desirable. Also, the person who has scored the lowest marks in any shift will be assigned a score of 0. Depending on the number of candidates in each shift the percentiles can be calculated or rounded off either to 5 or 6 decimal places. This is done to reduce the bunching effect and hence the number of ties. For example, if each shift has about 20,000 (or 2 x 105) candidates, then 5 decimal places will suffice. On the other hand, if the number of candidates in each shift is in lakhs (of the order 106), then 6 decimal places are recommended.
Calculation of Percentiles
The percentiles after normalization will be calculated in two parts as shown below.
