One Stop GATE Forum: GATE Score

Message


   
                    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. 
                    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 2003, this PI is scaled 
                      with respect to the global average and global standard deviation. 
                      This concept is represented as:

                       
                    where,


                    m_g = rescaled marks defined with reference to global 
                    average and standard deviation.


                    a_g = global average of marks of all candidates 
                    who appeared across all papers and years (2003-2006).


                    s_g = global standard deviation of marks of all 
                    candidates who appeared across all papers and years (2003-2006).

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

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

                       
                    Where, 
                      

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

                        
                          GATE Score Range
                          Ability Level
                        
                         
                          800 to 1000
                            Outstanding
                        
                         
                          675 to 800
                            Excellent
                        
                         
                          550 to 675
                            Very good
                        
                         
                          425 to 550
                            Good
                        
                         
                          300 to 425
                            Above average
                        
                         
                          100 to 300
                            Average
                        
                         
                          Below 100
                            Below average
                        
                      
The evaluation of the ORS is carried out by a computerized 
                  process using scanning machines, with utmost care. 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 (educational 
                  institutions, R and D laboratories, industries etc.) in India 
                  and abroad based on written request by the organization and 
                  on payment. Details can be obtained from GATE Chairmen of IITs 
                  / IISc.
