GATE Score Card

* Score card will be sent only to the qualified candidates. No information will be sent to candidates who are not qualified.

* The GATE score card is a valuable document. Care should be taken to preserve it. Additional Score Cards, (up to a maximum of two) will be issued on payment basis only once.

* The Score Card cannot be treated as a proof of category.

* The score card of the Qualified Candidates will include GATE Score, Percentile Score and Rank.

i. GATE Score

The GATE SCORE of a candidate is a statistical performance index in the range 0 to 1000. It reflects the ability of a candidate, irrespective of the paper or year in which he/she has qualified. Candidates with same GATE SCORE from different disciplines and/or years can be considered to be of equal ability i.e. they have same performance level.

The performance index (PI) of a candidate for his/her paper in a given year is defined as:

where,
m = marks obtained by the candidate.
a = average of marks of all candidates who appeared in the paper mentioned on this scorecard, in the current year.
s = standard deviation of marks of all candidates who appeared in the paper mentioned on this scorecard, in the current year.

To facilitate performance comparison across GATE papers and over a block of years since GATE 2004, this PI is scaled with respect to the global average and global standard deviation. This concept is represented as:

where,

mg = rescaled marks defined with reference to global average and standard deviation.
ag = global average of marks of all candidates who appeared across all papers and years (2004-2007).
sg = global standard deviation of marks of all candidates who appeared across all papers and years (For example 2004-2007).

Therefore the candidate’s rescaled marks can now be written as:

Considering 150 as the maximum marks in GATE paper, the rescaled marks, mg, is finally represented as the GATE Score on a 0 to 1000 scale and is given by:

where,

Therefore,

NOTE: The Maximum GATE Score can be 1000.

A typical qualitative interpretation of the GATE SCORE, for example, can be as follows:

ii. Percentile Score

The percentile score is not the same as percentage of marks. The percentile score of a candidate shows what percentage of candidates, who appeared in the same paper in GATE 2006, scored less marks than him/her. It is calculated as follows:
Let N be the total number of candidates appearing in that paper and nc be the number of candidates who have the same all India rank c in the same paper. Then all the candidates, whose all India rank is r, will have the same percentile score P, where

P = {(no. of candidates securing marks less than the candidate concerned)/N}x100

• Requests for revaluation of the answer script and re-totaling of marks will not be entertained.

The GATE result and particulars of the qualified candidates will be made available to interested organizations in India and abroad based on written request by the organization and on payment. Details can be obtained from GATE Chairmen of IITs / IISc.
