Perceptual information collection
A primary survey was conducted in August through September 2018, where 175 academic experts, 410 current students, 460 aspiring students and 75 recruiters from 23 cities in India nominated the best b-schools in the country. A closed-ended questionnaire was given to all the stakeholders, asking them to nominate and rank the top 25 b-schools in India and the top b-schools within their city.
Out of the total 1,120 interviews, 30 qualitative, in-depth interviews were done to understand the reasons for the rankings. This exercise helped in validating the data and providing a rationale for the rankings, wherever required.
Perceptual score: Calculated based on the number of nominations received and the actual ranks given to the b-school in the All India category and in its own city
Factual information collection
A dedicated website was created and the link was sent to more than 1,300 b-schools, of which 178 responded within the stipulated time. Nine b-schools were rejected because of incomplete data or lack of supporting documents. Data from the remaining 169 b-schools was used for the rankings.
Factual score: Information collected from the b-schools was combined by applying appropriate weights to each dimension as given below.
Age and infrastructure: 21.5%
Faculty and teaching: 13.5%
Entry standard: 25%
Alumni base: 5%
Ranking is based on a composite score derived by combining the perceptual score for the b-school and factual score.
Some b-schools could not respond to the survey with factual information within the stipulated time. For them, composite score was derived by combining the perceptual score for the b-schools with an interpolated appropriate factual score based on their position in the perceptual score list.
Some top b-schools, like IIM Calcutta, opted out of the survey and did not want their names to be published.
