What is Normalization in CAT?

CAT Score Normalization can be understood as a process to ensure fairness and equity in the performances of candidates across all sessions. The CAT normalization process includes adjusting location and scale differences of score distributions across different question papers. The scaled scores obtained by this process will then be converted into CAT percentiles. Candidates will be shortlisted for Written Ability Test (WAT), Group Discussion (GD) and Personal Interview (PI) rounds on the basis of CAT percentile.

  • CAT score (scaled)
  • Class 12 marks
  • Class 10 marks
  • Graduation score
  • Work Experience
  • Diversity (Gender)
  • Diversity (Academic)

Take a look at CAT Composite Score calculator for shortlisting for WAT-PI, issued by IIM Lucknow:

CAT Composite Score Formula

CAT Normalization Process is based on GATE scoring, where the normalization is based on the assumption that distribution of abilities of candidates is the same across all the sessions. The calculations are based on statistic equations.

GATE formula

In GATE, normalization takes into account all the variations in the difficulty levels of the question papers across different session.

GATE Normalization Process

"The normalization is done based on the fundamental assumption that "in all multi-session GATE papers, the distribution of abilities of candidates is the same across all the sessions". This assumption is justified since the number of candidates appearing in multi-session papers in GATE is large and the procedure for allocation of session to candidates is random. Further, it is also ensured that for the same multi-session paper, the number of candidates allotted in each session is of the same order of magnitude," informs the official GATE website.

Here's GATE normalization formula:

GATE formula for calculation

Normalized marks based on the above formula will be calculated corresponding to the raw marks obtained by the candidate in CAT 2025.

Candidates should practice at least past 10 years' CAT question papers to have a good control over the exam. Many times, questions are repeated so prior practice will be helpful. CAT question papers are also best source of RC passages.

Yes, the question papers of all CAT exam slots are different from each other. This is done to ensure that there is no question leak before the next slot, and that second and third slot candidates have no advantage over first slot candidate.
