Normalisation of CAT Scores in 2020

CAT 2020 shall be conducted in three sessions. Three different Test Forms shall be administered in three Test Sessions. In order to ensure fairness and equity in comparison of performances of candidates across different test sessions, the scores of candidates shall be subjected to a process of Normalisation.

  • The Normalisation process shall adjust for location and scale differences of score distributions across different forms.
  • After normalisation across different forms, the scores shall be further normalised across different sections.
  • The Scaled Scores obtained by this process shall be converted into percentiles for purposes of shortlisting. For reporting purposes, Scaled Scores for each section (Section I: Verbal Ability and Reading Comprehension (VARC), Section II: Data Interpretation and Logical Reasoning (DILR), and Section III: Quantitative Ability (QA)) and Total along with the Percentiles shall be published.
  • The process of Normalisation is an established practice for comparing candidate scores across multiple Test Forms and is similar to those being adopted in other large educational selection tests conducted in India, such as the Graduate Aptitude Test in Engineering (GATE). For normalisation across sections, we will use the percentile equivalence.
