Previous year CBSE had to face a lot of flak over errors in evaluation of the answer sheets of Class 10 and 12. The board has taken this very seriously and would be taking strict action against the evaluators to the extent of even expulsion for being careless.

CBSE engages experienced teachers for an error free evaluation process, trains them as well as provides them with marking scheme and guidelines. The evaluation centres are under CCTV surveillance to too. Last year following re-evaluation, marks for more than 70% of the answers sheets had increased.
