RRB NTPC Percentile Normalization 2024 :- Railway Recruitment Board has informed through a notification on 4th November 2024 that the normalization process of Non Technical Popular Category (NTPC) and 12th level recruitment will be changed. The normalization method has been changed in this recruitment and its information has been released on the official website of RRB. Before this recruitment, this method was used in RRC Group D 2019 recruitment. What is the new normalization percentile score or marks. It’s complete information is given in this article below. If you have applied in this recruitment then see this page carefully.
(1) Percentile Scores: Percentile Scores are scores based on the relative performance of all those who appear for the examination. The marks obtained are transformed into a scale ranging from 100 to 0 for each shift of examinees. The Percentile Score is not the same as the percentage of marks obtained.
(2) The Percentile Score indicates the percentage of candidates that have scored EQUAL TO OR BELOW (same or lower raw scores) that particular Percentile in that examination. Therefore, the topper (highest score) of each shift will get the same Percentile of 100 which is desirable. The marks obtained in between the highest and lowest scores are also converted to appropriate Percentiles.
(3) The Percentile Score will be the Normalized Score for the examination (instead of the raw marks of the candidate) and shall be used for the preparation of the merit lists.
(4) The Percentile Score of a Candidate for a particular shift will be calculated as below.
Number of candidates appeared in the ‘Shift’ with raw score EQUAL TO OR LESS than the candidate Percentile Score = ——————————————————————————- x100 The total number of the candidates who appeared in the ‘Shift’
(5) The Percentile Scores for the raw score of all the candidates for all the shifts would be merged and shall be called the RRB Scores (RRC scores- For Level-1 Exam) which will then be used for the compilation of results and further processing for deciding the merit allocation.
(6) The Percentile Scores will be calculated up to 5 decimal places to avoid the bunching effect and reduce ties.
(7) In case of two or more candidates securing same Percentile Score, their merit position shall be determined by age criteria i.e., older person shall be placed at higher merit and in case age being same, then alphabetical order (A to Z) of the name shall be taken into account to break the tie.
(8) In order to finalize the Merit based on Percentile Score as mentioned above it is necessary to include only those candidates in the Merit list who have secured Minimum Percentage of Marks {for eligibility in various categories: UT-40%, EWS40%, OBC (Non creamy layer)-30%, SC-30%, ST-25% (ST-30 % for Level-1 Exam)} as per qualifying criteria given in the CENs.
(9) For this Normalized Marks of each candidate will also be calculated as detailed below which will be basis for deciding who are the candidates that have scored Minimum Percentage of Marks as per qualifying criteria given in the CENs as well as for giving weightage in marks to CCAA candidates for Level-1 Exam.
Selection of Base Shift :
“Base Shift” is a shift having the “Highest Mean” (Average) among all the Shifts of CBT with a condition that its Present Candidate Counts should be 70 % or more than the average of all Shifts”. In case the “Highest Mean” of two Shifts are same then Shift having “Highest Individual Marks” shall be considered as “Base Shift”. In case both the “Highest Mean” and “Highest Individual Marks” are same then the Shift having “Highest Present Count” shall be considered as “Base Shift” to break the tie.”
Calculation of Normalized Marks :
X is the percentile score of a candidate. If X percentile score is found in Base Shift, then corresponding Normalized Marks (N) are directly available. Otherwise following standard mathematical formula of interpolation is to be used.
