Normalisation Means

Normalization, as used in the Indian context, is a process for ensuring the students neither
advantaged nor disadvantaged by the difficulty of examinations conducted in multiple
sessions. This process is based on a simple formula which has been adopted as recommended
by the experts from reputed educational institutions at all India level and Universities. The
process is being implemented in other all India / Nationwide entrance tests for admission into
undergraduate and graduate professional courses. Normalization process ranks all the
candidates across all sessions on a comparative scale. In any normalization process, the marks
of the easier session may be reduced marginally and the marks of the harder paper may
increase marginally on the global level, depending on the average performance in each
session. If there is no much difference in the averages between the two sessions then there
wonβ€Ÿt be much difference in the normalized marks as well. Normalizing marks would justify
the candidates while protecting their actual performance.

AP EAPCET Normalisation Process

The main aim of the normalization is to justify the candidates who got a difficult paper
compared to an easier paper. Hence, the task is to rationalize in the best possible sense and
rank the candidates based on the global performance. Various national level examination
bodies like JEE (Main), GATE etc. are currently adopting such normalization procedures.
Correspondingly, EAPCET committee has deliberated extensively and decided to use the
following normalization procedure.
Normalized marks of the student

𝐺𝑀𝑆 + { ( π‘‡π‘œπ‘ π΄π‘£π‘’π‘Ÿπ‘Žπ‘”π‘’ πΊπ‘™π‘œπ‘π‘Žπ‘™ – 𝐺𝑀S)/(π‘‡π‘œπ‘ π΄π‘£π‘’π‘Ÿπ‘Žπ‘”π‘’ π‘†π‘’π‘ π‘ π‘–π‘œπ‘› βˆ’ 𝑆𝑀S)}Β  Γ—Β  ( π‘€π‘Žπ‘Ÿπ‘˜π‘  π‘‚π‘π‘‘π‘Žπ‘–π‘›π‘’π‘‘ 𝑏𝑦 πΆπ‘Žπ‘›π‘‘π‘–π‘‘π‘Žπ‘‘π‘’ – 𝑆𝑀𝑆)

where
SMS: (Average + Standard Deviation) of the session in which the candidate belongs to
GMS: (Average + Standard Deviation) of all the candidates across all sessions together
Top Average Session: Average marks of the top 0.1% of the candidates in the session in which the candidate belongs to

Top Average Global: Average marks of the top 0.1% of all the candidates across all
sessions together

Weightage for Assigning Merit Rank

75% of AP EAPCET normalized marks and 25% of Intermediate Marks in group subjects to
prepare the rank.
Note:

  • Β For Candidates having qualifying marks in AP EAPCET-2023, if after normalization, the
    marks(s) in any individual subject(s) become negative, then the normalized mark(s) in the
    respective subject(s) are treated as zero. However, total marks in three subjects are
    considered as EAPCET marks.
  • For the candidates for whom there is no qualifying cut-off in AP EAPCET – 2023, if the
    marks in all the three subjects after normalization go below zero (negative), the total marks
    are treated as zero and the rank is assigned. If the tie persists then APEAPCET 2023
    normalization marks (though negative are considered for breaking the tie.

Example

The following is based on sample data to explain the normalization process. The data is based
on an almost equal number of candidates in all four sessions. The normalization is shown
subject wise so that students get the benefit based on subject wise performance rather than the
entire paper in a session.
Averages and Standard Deviations in a particular session and averages of top 0.1%
candidates of a particular session, Global Average and Standard Deviations of all sessions
together, Averages of top 0.1% candidates in all sessions is given in Table
1. Example data of normalized marks is shown in Table 2 to Table 5.
