The CBSE, which has over 18,000 schools affiliated to it, decided to do away with the marking system this April but the Delhi high court asked it to continue this year. The working group is headed by the CBSE chairman and has members from the ICSE and states of Gujarat, J&K, Karnataka, Telangana, Chhattisgarh, Kerala and Manipur.

CBSE officials said the move of the board will be futile unless all state boards decide to remove the spiking of marks by amending their rules and regulations.

“It will put CBSE students in a disadvantageous position. Complete parity should be maintained among all boards, including state boards. We will convey our decision to them and if everyone agrees, it will have to be implemented before October as students will start filling up forms for the board exams then,” a central board official said.

The moderation policy allows the country’s biggest school board to give students extra marks. But some state boards used the system to increase marks of their students, spiking the overall pass percentage and thereby triggering widespread resentment.

States such as Haryana, Himachal Pradesh, Maharashtra and Bihar do not have a moderation policy. But others, including Goa, Tamil Nadu and Uttarakhand, use the policy to improve their pass percentage.
