1. What is Normalisation?

𝟔𝟎% 𝒐𝒇 𝑩𝒐𝒂𝒓𝒅 𝑴𝒂𝒓𝒌𝒔=𝟔𝟖𝟔𝟓𝟏𝟑𝟕𝟏𝟏∗𝟏𝟎𝟎
Normalisation as used in the
Indian context is a process for ensuring that students are neither advantaged
nor disadvantaged by the difficulty of exams that they do for the Boards. This
process is used in other countries with similar issues as in India
𝑷𝒆𝒓𝒄𝒆𝒏𝒕𝒊𝒍𝒆=𝟓𝟎.07
2. Normalisation Process
requires us to know the following
Percentile Score
Percentile score of a Candidate
in a Board or JEE (Main ) will reflect what
Percentage of Candidates have scored below that Candidate in that Board or JEE
(Main) Examination.
A Percentile score is the value
of below which a certain Percent of observations fall. For example, the 20th
Percentile is the value (or score) below which 20 Percent of the observations
may be found.
The Percentile of a Candidate
will be calculated as
Example : Suppose we have ,
13711 Candidates in a Board ABCD and a Candidate who has scored 60% of Board
marks has 6865 Candidates below him; his Percentile score will be calculated as
follows
| Table 1: Percentage and corresponding Percentile score of 13711 Candidates of Board ABCD. Board Percentage (B0) | No of candidates below candidate the with Board Percentage B0 | Percentile Calculation corresponding to B0 | Percentile Score |
