Survey Methodology

The objective of this research was to arrive at a list of top schools in each zone in Delhi NCR. The study had two major modules i.e. Factual survey & Perceptual rating survey.

In the perceptual survey module, a strucutred questionnaire was administered to selected respondents to arrive at a ranking & rating of schools in Delhi. The sample selection was done using convenience sampling method though the sample was spread out geographically to get better representation. The initial list of schools had over 550 schools of Delhi NCR, though each respondent was asked to give ratings for only those schools that he/she is aware of and considers it to be among the top 10 schools in Delhi/NCR, Top 10 Schools in Respective Zone and Top 5 Schools with International Curriculum Delhi/NCR. Thus a maximum of 25 schools were rated by each respondent. This ensured that there was neither interviewer nor respondent fatigue and thus ensured better quality data.

A sample survey of 1115 was conducted in (All 11 zones)

  1. North
  2. East
  3. West
  4. South East
  5. South West
  6. Central
  7. Noida
  8. Greater Noida
  9. Gurgaon
  10. Ghaziabad
  11. Faridabad

The geographical spread of the sample was ensured by selecting multiple starting points spread across the city.

There were two main respondent categories who were interviewed to evaluate schools; those who had the experience of such schools (Experiential) and those who are currently searching and aspiring to get admissions for their ward and evaluating these schools (Perceptual). The respondent categories included:

  • School teachers
  • Alumni
  • Experienced parents
  • Students
  • Aspiring parents

Extensive Fieldwork was conducted for 6 weeks, starting from 1 week of Aug 2017

Extensive Fieldwork was conducted for 6 weeks, starting from 2nd week of July 2016


The module 1 was a secondary research module. A comprehensive list of schools was generated with the help of internet, magazines and other publications. The various sources used for generation of school list included:

  • CBSE approved list of schools
  • List of school from previous surveys
  • discussion with industry experts to add/ delete any school to ensure we have a comprehensive list

In addition, two criteria for short listing were applied

  • Schools that have at least 3[Is it 3 or 5 batches] batches as of April 2017, and
  • Schools that have been in existence for at least 3 years

As it is not possible to get a completely exhaustive list of schools and include them in the survey, we had option of adding any new school name in the survey form if any respondent mentioned any school name outside our list. Effectively, every school had a chance of getting covered in the survey if their name was mentioned by the respondents.

Module 2 | Factual data collection

More than 550 schools were sent the factual data questionnaire and then rigorously followed up through telephonically.

The factual data sheet focuses on the following information areas:

  • General information of the School: Establishment, Affiliation etc.
  • Infrastructure & facilities
    • Sports facilities in your school
    • Cultural/extra-curricular facilities in your school
    • Medical facilities in your school
  • Teachers
  • Potential to network
  • Exchange programs and global exposure
  • Awards

Module 3 | PERCEPTUAL data collection

A perception questionnaire was administered to respondents. Respondents were asked to give rating for only those schools which they were aware of and had included them in their list of top schools in Delhi or their zone.

Respondents were provided a list of parameters to evaluate the schools & rate on a scale of 1-10 where 1 means poor & 10 means for excellent. The list of parameters covered in the survey was arrived at based on past surveys as well as discussions with experts from the industry experts and teachers etc. As mentioned the 5 different stakeholders were taken into consideration for the perceptual survey viz. Teachers, Alumni, Parents of aspiring students, Parents of existing students & Students.

The questionnaire was so designed that both experiential & perceptual target respondents could be exposed to the same set of parameters – this ensured that the scores of different stakeholders could be correlated and collated to arrive at a single final score.

module 4 & 5 | Analysis: Final ranking of School

A robust approach is followed to arrive at the final rankings. The step by step process is given below:

Perceptual Score

  • Ratings on various parameters for each school
  • Calculating importance of various parameters to arrive at weights for each parameter – we use a regression model to arrive at the importance of various parameters
  • Calculation of raw scores and weighted scores for each parameter
  • Calculation of overall score for each school using importance weightages.

Factual Score

  • The information collected corresponding to similar parameters as in the perceptual survey
  • A detailed scoring system has been developed for each parameter
  • After assigning scores to each parameter, raw scores are calculated
  • The raw scores are weighted by their importance to arrive at weighted scores
  • The final school score is calculated as in the perception survey
  • The final score for a school are a weighted average of Perception Score and Factual Score - equal weight age given to both
  • While calculating the ranking – those schools which participated in the factual survey were considered first & schools which dint not participate in the factual survey (assigned average factual score) were considered only after that.

Defining Categories in Final Ranking


Schools that have been in existence for more than 5 years and have 5 or more pass out batches, are respected by the community for their academic performance and infrastructure, and are generally viewed as the best. For the purpose of this research only schools that have had at least five batches of class XII graduates were considered for this ranking.


Waiting-in-the-ranks schools - ready to grab the initiative from the leaders in the blink of an eye. This set comprises of schools that have scored well in the research but didn’t feature in the top 10 but have potential to be in leader category in future. Some of these school could be in existence for a lesser than 5 years.


There are some schools who have implemented innovative approaches of imparting education; such schools were considered for “Innovators” category. Their ranks have been assigned, considering both qualitative & quantitative performance. Typically, these were schools who recently started.

Some caveats/assumptions:

Best efforts were made to reach every schools in Delhi NCR; however, any school that did not send complete “Fact-Sheet” within the allotted time was assigned an average Factual score for calculating their overall ranking

Any school which expressly stated that it did not wish to participate in the survey was excluded from the survey

Present survey has been conducted by an independent Research Agency named i3RC Insights using stated methodology for arriving at given rankings.
