RRB NTPC Marks Calculator, Check Score Normalisation Formula

RRB NTPC Marks Calculator

RRB NTPC Marks Calculator: The Railway Recruitment Boards (RRBs) defines NTPC score calculator. RRB NTPC marks calculator is used to calculate the scores of candidates based on the normalisation. RRB has set the normalisation method to calculate RRB NTPC CBT exam score. RRB NTPC marks calculator is a scientific and statistical process. It involves the analysis of the raw score of candidates, mean and standard deviation of the raw marks of candidates in their session as well as other sessions to arrive at the normalised marks. The normalisation is done based on percentile based marks calculation. Percentile Scores are scores based on the relative performance of all those who appear for the examination. The Percentile Score will be the normalized score for the RRB NTPC exam (instead of the raw marks of the candidate) and shall be used for the preparation of the merit lists. 

RRB NTPC is being conducted to fill up vacancies for the posts of  Non-Technical Popular Categories (NTPC) i.e. Junior Clerk cum Typist, Accounts Clerk cum Typist, Junior Time Keeper, Trains Clerk, Commercial cum Ticket Clerk, Traffic Assistant, Goods Guard, Senior Commercial cum Ticket Clerk, Senior Clerk cum Typist, Junior Account Assistant cum Typist, Senior Time Keeper, Commercial Apprentice and Station Master in various Zonal Railways and Production Units of Indian Railways.

Candidates should note that the normalisation methodology will be followed for normalisation the raw scores since the exam is conducted in multiple shifts. For this, percentile based normalisation of marks will be done.  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.

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. 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.

Formula for RRB NTPC Marks Calculator

The Percentile Score of a Candidate for a particular shift will be calculated as below: 

Percentile Score=Number of candidates appeared in the ‘Shift’ with raw score EQUAL TO OR LESS than the candidate/ The total number of the candidates who appeared in the ‘Shift’ X 100

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 the 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.

RRB NTPC Marks Calculator: Important Points

The important points related to normalisation of marks are given below:

• 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.
• The Percentile Scores will be calculated up to 5 decimal places to avoid the bunching effect and reduce ties.
• 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
• 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 exam
• This will also be the basis for deciding who 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
