While 40 percent of the evaluation will be through formative assessment, the rest will be through summative assessment.

The CBSE official disclosed this to IANS soon after Human Resource Development Minister Kapil Sibal announced that Class 10 board examination under CBSE would be abolished from 2011.

Sibal said: 'There will be no Class 10 board examination from 2011.' The last Class 10 CBSE Board examination will take place in March-April 2010.

But the minister clarified that the exams would very much take place this academic year.

From 2011, the students' evaluation would be based exclusively on a nine-point grading system. But this will be introduced this academic year itself.

'This academic year, there will be both a Board examination and a grading system,' the minister said.

Under the new system, there will be nine grades: A1, A2, B1, B2, C1, C2, D, E1 and E2.
