RRB Normalization Method & Formula 2026 Out

As per the official notification, RRB will opt for the Percentile Score method to normalise candidates’ scores across different shifts. The notice released on 9th February 2026, explains of how raw marks will be converted into percentile scores and normalised marks to ensure fairness in exams conducted in multiple shifts.

What is a Percentile Score?

Percentile scores reflect the relative performance of candidates in a particular shift. The percentile score will serve as the RRB Score (RRC Score for Level-1 exam) and will be used for merit preparation

The marks are converted into a scale ranging from 0 to 100.
The topper of each shift will receive a percentile score of 100.
The percentile score is not the same as the percentage of marks.

Percentile Formula

Tie-Breaking Criteria

Percentile scores will be calculated up to 5 decimal places to reduce tie cases. In case two or more candidates secure the same percentile score:

Older candidate will be placed higher in merit.
If age is also the same, alphabetical order (A to Z) of the name will be considered

Minimum Qualifying Marks

Only those meeting the qualifying criteria will be considered for further processing. Candidates must secure the minimum qualifying percentage to be included in the merit list:

Category	Minimum Qualifying Marks
UR	40%
EWS	40%
OBC (NCL)	30%
SC	30%
ST	25%
ST (Level-1 Exam)	30%

Calculation of Normalized Marks

If a candidate’s percentile score is found in the Base Shift, the corresponding normalised marks are directly taken. Normalized marks will be used to determine eligibility for minimum qualifying marks and weightage (including CCAA weightage for Level-1 exam).
