As per the genuine rules of Government of India if any candidate is willing to appear for any State board or Central Board Class 10th Examination he should be of minimum 14-15 years old age as per the date of commencement of examination. So in case of all ICSE, CBSE and State boards the student should be 14-15 years old age to appear for 10th Examination.
