According to Council for the Indian School Certificate Examination (CISE) which conducts class X and XII examination, before they declared the results they waited for the CBSE's decision on moderation policy.
The CISCE conducts both the ICSE and ISC exams.
In 2016, the ICSE (Class X) and ISC (Class XII) results were declared on May 6.
However, this time the CISCE attributed "some" delay to the elections in five states -Punjab, UP, Manipur, Uttarakhand and Goa - due to which the exam schedule was delayed.
"We waited for first the Delhi High Court order and then for CBSE's stand on the issue as the in-principle decision to scrap moderation policy was taken unanimously by 32 boards," said Gerry Arathoon, CEO of the Council.
The Council today declared results for both class XII, which saw a pass percentage of 96.47, and class X with 98.53 per cent as girls once again outshone boys.
CBSE had on Sunday announced results for class XII examination registering a dip of over one per cent in pass percentage.
The fate of the results was undecided till last Friday as Delhi High Court had ordered a stay on scrapping of the moderation policy of awarding of grace marks by CBSE.
After contemplating moving the Supreme Court, the CBSE decided against it as the process would have delayed the results further.
Human Resource Development Minister Prakash Javadekar had yesterday categorically said that the ministry will not intervene in the matter and it is for boards to take an academic call on the issue.
