CBSE 75% Attendance Rule: How to Calculate and Track It

TL;DR: CBSE requires at least 75% attendance for a student to sit the Class 10 or 12 Board exam. Attendance % = days present ÷ working days × 100, counted from the start of teaching to the cut-off. Under the August 2025 circular, attendance is calculated up to 1 January, and shortage cases must reach the Regional Office by 7 January. Relaxation is possible only for documented serious reasons, and CBSE decides. Track every Class 10 and 12 student monthly from the start of the session so no family is surprised in December.

Not legal advice. Rules change; always check the latest circular on cbse.gov.in for your session.

What the rule actually says

CBSE's Examination Bye-Laws for regular candidates require a student to have at least 75% attendance in the classes held to be eligible for the Board exam (CBSE bye-laws, regular candidates). The same page says:

• Attendance is counted from the day teaching of Class X/XII starts, up to the 1st of the month before the month in which the Board exams begin.
• Students in subjects with practical work also need 75% attendance in practicals.
• Authorised participation in sports meets, NCC/NSS camps and related travel counts as attendance.
• A student who migrated from another recognised school can have attendance there counted.

On 4 August 2025, CBSE issued a circular titled "Strict compliance with attendance requirements for Board Examination Eligibility" for the 2025–26 session. It reiterated Rules 13 and 14 and added a clear procedure for schools.

The key dates (from the 2025 circular)

Date	What happens
Start of session	School informs students and parents in writing about the 75% rule and the consequences
Through the year	Registers updated daily, signed by the class teacher and a competent school authority
1 January	Attendance calculated up to this date
7 January	Last date for shortage cases to reach the CBSE Regional Office
Within 15 days	Regional Office points out deficiencies; school fixes them within 7 days
7 February	Final date for approvals

Cases without the mandatory documents, or received late, are rejected.

When relaxation is possible

The 2025 circular describes a relaxation of up to 25% only for exigencies, with documents:

• Prolonged illness: parent's request, medical certificate from a Government doctor, medical reports, and the school's recommendation on the prescribed proforma
• Loss of a parent or similar circumstances: death certificate or certificate from the competent authority, parent's request, school's recommendation
• Other serious reasons of a similar nature: certificate from a Government authority, parent's request, school's recommendation
• National or international sports: proof of authorised participation, Sports Authority of India recommendation where required, school's recommendation

The older bye-law page on the CBSE site describes a smaller condonation limit, with cases below 60% considered only in exceptional medical circumstances. Where the two seem to differ, follow the latest circular and confirm with your Regional Office. Either way, the decision is CBSE's, so never tell a parent that a shortage "will be condoned".

What the circular expects from schools

• Written leave applications at the time of leave, with supporting documents. Leave without a written request is treated as unauthorised absence.
• For medical emergencies, the application and medical documents should be submitted immediately after the leave.
• Registers updated daily, signed, and available for inspection.
• Parents of students who are often absent warned in writing (Registered/Speed Post or email), with copies kept on record.
• Once a shortage case is submitted, attendance records cannot be changed. Later corrections are treated as manipulation.
• CBSE may conduct surprise inspections. Students absent without proper records may be treated as non-attending ("dummy") candidates and not allowed to sit the exam, and schools with poor records risk strict action, including disaffiliation.

How to calculate attendance percentage

Attendance % = (Days present ÷ Total working days) × 100

"Total working days" means the days the class actually met, from the start of teaching to the cut-off, not the calendar days in the year.

Example: Class 10 teaching started on 1 April. Up to 1 January, the school had 190 working days. A student was present on 150.

150 ÷ 190 × 100 = 78.9%. Eligible, with a small margin.

How many more days does a student need?

If a student is below 75%, the number of consecutive days they must attend to reach 75% is:

Days needed = (3 × working days so far) − (4 × days present)

Example: 120 working days so far, 84 days present (70%). (3 × 120) − (4 × 84) = 360 − 336 = 24 more days of unbroken attendance.

How many days can a student miss in the whole period?

Maximum absences = 25% of the total working days up to the cut-off.

If you expect about 200 working days up to 1 January, a student can miss at most 50 of them, so must be present on at least 150.

Excel formulas for the office

With working days in column C and days present in column D:

• Attendance %: =ROUND(D2/C2*100,1)
• Days needed to reach 75%: =MAX(0, 3*C2 - 4*D2)
• Flag: =IF(D2/C2<0.75,"BELOW 75%",IF(D2/C2<0.8,"WATCH","OK"))

The "WATCH" band at 75–80% matters most. Those are the students one bout of fever away from a shortage.

A monthly routine that prevents January panic

1. First week of the session: send the written 75% notice to every Class 10 and 12 parent; keep a signed or emailed copy.
2. Every month, by the 5th: calculate each Class 10 and 12 student's attendance % up to the 1st.
3. Same day: list students below 80%. The class teacher talks to each one.
4. Below 75%: send a written warning to the parent (Speed Post or email, as the circular describes), and keep a copy.
5. Collect leave documents immediately, not in December. A medical certificate requested months later is hard to get and easy to doubt.
6. November review: the principal checks every student under 80% individually, and identifies cases that may need a relaxation request with documents ready.
7. 1–7 January: final calculation, shortage cases filed with full documents, records frozen.

Paper register or software?

The circular asks for registers that are updated daily, signed and available for inspection. Many schools keep a signed register and use software or Excel alongside it for the monthly calculation.

Software helps most with steps 2–4: teachers mark attendance daily, and the office can pull reports without adding up registers by hand. In EduTechMonitor, teachers take daily attendance and the office can run attendance reports, and parents can see their child's attendance from the parent login, which helps families notice a problem early. EduTechMonitor does not send automatic SMS or WhatsApp absence alerts, and it does not file anything with CBSE for you; the written notices and shortage cases remain the school's job.
