The Government on Monday announced that it will introduce grading system in all Central Board of Secondary Education (CBSE) schools and make Class X board exams optional from coming academic year (2010-11). Union Human Resource Development minister Kapil Sibal,during a press conference in the national capital,said: Central Advisory Board of Education (CABE) supports making Class X examination optional in CBSE system. There is a pan-India consensus over the issue. So we have decided to go ahead with this, Sibal said. The Class X board exams will become optional in all CBSE schools from the coming academic year (2010-11). As per sources,the CBSE has prepared the format of an aptitude exam which schools can use to test Class X students on their level of understanding in each subject. The emphasis,however,will be on continuous and comprehensive evaluation (CCE) through the year instead of a single public exam at the end of Class X.
