Hello,

1) In CBSE improvement examination a candidate will get a chance to re-appear in one or more subject in the consecutive years board examination.

2) Students who have cleared the previous years board examination are also eligible to apply for CBSE improvement examination.

3) Sudents who have appeared in the last year’s board examination, their personal details will be auto generated while registering for the improvement examination. But the students who appeared two years ago they will need to fill their personal details while applying for the improvement examination.

4) Students who didn’t passed the previous year board examination are not eligible to apply for the improvement examination. They need to appear as a private student on the next year or they can appear for the compartment examination.

5) If a student is not able to perform well in the improvement examination then their best performance in both the exams will be considered.

These are some criteria listed by council.

hope it helps.
