We have defined International Schools as those schools which offer international programmes i.e curriculum of international boards like IBO, Geneva, CIE and Edexcel UK and The College Board USA from at least class 8 onwards.
In case a school is also offering Indian curriculum, at least 30% of students should be taking the offshore board examination. Embassy schools have not been included since they cater to expats and not to Indian citizens.
The ranking of schools is based on perceptual survey of 1126 teachers and parents belonging to SEC A segment in Delhi and the NCR.
Objective data was also collected from schools using a structured questionnaire. The final ranking was arrived at by combining perceptual and objective data scores.
