The Madhyamik board will neither set the question papers for the Class IX annual exams nor get the answer scripts checked by external examiners this year.
All schools under the board will conduct the exams on their own as they have done so far.
Kalyanmoy Ganguly, the administrator of the West Bengal Board of Secondary Education, said on Tuesday that the centralised tests had to be deferred because several Madhyamik schools were not ready for the new system.
Many schools, particularly those in the rural areas, do not have the facilities to store confidential documents like question papers, said Ganguly. The Class IX annual exams are slated for November.
Ganguly said the board had completed preparations for implementing the new system. For example, the question papers had been set.
Several schools had informed the board that they did not have the rooms and trunks to store question papers. Question will get leaked if the papers are not kept properly, said a board official.
Madhyamik is the only centralised exam conducted by the board now. Its question papers are kept in police stations and treasury offices.
One of the objectives behind making the Class IX annual exam centralised is to accustom the students to board exams.
The HS council has been setting question papers for the Class XI annual exams since 2008.According to Ganguly, many students had also told the board that they were not prepared to sit for a centralised examination.
