What it is

CBSE requires at least 75% attendance for a student to appear in the Class 10 and Class 12 board exams, under Rules 13 and 14 of its Examination Bye-Laws. Attendance is days present divided by the school's working days. A shortfall can be condoned only in serious, documented cases, such as prolonged illness with medical certificates, the death of a parent, or participation in national-level events, and only through the school. This calculator shows where a student stands today and what it takes to stay at or above 75% for the session.

What you get

Your percentage today

Days present divided by working days, shown to one decimal and never rounded up past the line.

Days you can still miss

If you are above 75%, how many days you can be absent from today and still stay at 75% or more.

Days needed to recover

If you are below 75%, how many days in a row you must attend to climb back.

The whole session

Add the working days left and see the minimum days present for the full session, or whether 75% is still reachable.

Any target, not just 75%

Some schools ask for 80% or 85%. Change the target and the numbers update.

How it works

  1. Find the working days so far and the days present, from the school diary, app or report card.
  2. Enter them above. Add the working days left in the session if you know them.
  3. Read the result: your percentage, the days you can miss, or the days you need.
  4. If 75% is out of reach, talk to the school early about condonation.

Who it's for

  • Class 10 and 12 students checking board exam eligibility
  • Parents worried about absences after an illness
  • Class teachers answering "can my child still sit the exam?"
  • School offices preparing attendance shortage lists

Questions schools ask

What is the minimum attendance for CBSE board exams?

CBSE requires at least 75% attendance for Class 10 and Class 12 students to appear in the board exams, counted against the school's working days. Students below 75% are not allowed to sit the exams unless the shortfall is condoned.

How is attendance percentage calculated?

Divide the days present by the total working days and multiply by 100. For example, 88 days present out of 120 working days is 73.3%, which is below 75%.

Can CBSE condone attendance below 75%?

Only in serious, documented cases such as prolonged illness with medical certificates from a government doctor, the death of a parent, or participation in national or international events. The school sends the case to CBSE by the deadline in that year's circular, and the student cannot apply directly.

How many days in a row do I need to reach 75%?

Enter your working days and days present in the calculator. It works out the smallest number of consecutive days present that brings you back to 75%. Every day missed needs about three days present to make up.

Can a school track this automatically?

Yes. In Chalkbell, working days come from the school's academic calendar and holidays, attendance comes from RFID gate taps or the teacher's app, and each student's percentage is always up to date, so shortfalls are spotted months before the board exam.
