In the year 2015, the Ministry of Human Resource Development (now called Ministry of Education) had asked the Council for the Indian School Certificate Examinations (CISCE), which conducts the ICSE and the ISC examinations, to furnish evidence to justify its existence.
In 2013, a 20-year-old Indian student studying in the US, Debarghya Das, claimed in his personal blog to have downloaded the ICSE scores for over 100,000 students by scraping. His analysis of the data showed interesting patterns in the marking system, suggesting that the marks were rounded off with no student getting under 33 marks out of a possible 100. The reason for this was reportedly attributed to moderation; a practice also followed by Central Board of Secondary Education (CBSE), it involved tweaking candidates' marks to account for paper variances.
