Every semester, a group of students discovers in the same week that they are short on attendance and that “condonation” exists. The two facts arrive together, and the second one gets read as a solution.
It is not a solution. It is permission you have to apply for, on grounds someone else judges, usually with a fee — and every university publishes a floor beneath which it is not available at all.
Here is what the regulations actually say, university by university, with the clause numbers so you can check your own.
These figures are for R22. If you were admitted in 2025–26 or later you are under R25, where the promotion rule is completely different and there is no separate minimum for internal marks. See what changed in R25 before using anything on this page.
Source: JNTUH R22 B.Tech Academic Regulations (official PDF) . Clauses 6.1, 6.2 and 6.4 of the R22 B.Tech Academic Regulations. JNTUH requires 75% in aggregate; between 65% and 75% a shortage may be condoned on genuine grounds, and below 65% the regulation says it shall in no case be condoned. Checked 22 August 2026.
Condonation is permission, not a right — where a university offers it at all, it is granted on stated grounds, usually with a fee and an application through your college. Treat the middle band as “ask immediately”, not as “you are fine”.
JNTUH: 75% required, 65% floor
Under R22, clause 6.1 requires 75% attendance in aggregate across all courses to sit the semester end examinations. Clause 6.2 allows a shortage of up to 10% — that is, 65% and above but below 75% — to be condoned by the college academic committee on genuine and valid grounds, with supporting evidence.
Clause 6.4 closes the door: below 65% in aggregate “shall in no case be condoned”.
R25, which applies from the 2025–26 intake, carries the same rule at clauses 7.1, 7.2 and 7.5. The numbers did not change; the clause numbers did.
JNTUK: the second condition nobody mentions
JNTUK R23 asks for the same 75% in aggregate — and then adds something JNTUH does not. Clause 17 also requires a minimum of 40% attendance in each individual subject.
That catches people. A student can sit comfortably above 75% overall while one subject quietly sits at 30%, and the aggregate figure hides it completely. Condonation of the aggregate shortage is granted by the College Academic Committee on payment of a stipulated fee; below 65% the regulation says it shall in no case be condoned.
If you are at JNTUK, calculate per subject, not just overall.
VTU: per course, and only 5% of slack
VTU’s 2021 scheme is stricter in a way that is easy to miss. Clause 21OB5.1 requires 75% attendance in each course — not as an aggregate across courses. A strong overall figure does not rescue a single weak subject.
The condonable margin is also narrower: up to 5%, giving an effective floor of 70%, and it is condoned by the Vice-Chancellor on the Principal’s specific recommendation rather than by a committee at the college.
If you joined under VTU’s 2022 scheme, the requirement is 85%, not 75%. That is a materially different rule, and applying the 2021 figure to a 2022-scheme student gets the answer wrong by ten percentage points.
Anna University: not condonation at all
Anna requires 75% in each course under clause 11.1. What it does not have is a general condonation band you can apply into.
What the 2023 regulations provide is narrower and worth understanding precisely: a student with at least 65% attendance may have absence during a medical emergency excluded, on a certificate submitted within the stated window. That is an exclusion of specific days for a specific documented reason — not a fee-based waiver of a general shortfall.
Below 75% without that exclusion, the student is barred from the end semester examination for that course.
The comparison, in one place
| University | Required | Basis | Floor |
|---|---|---|---|
| JNTUH R22 / R25 | 75% | Aggregate | 65%, then never |
| JNTUK R23 | 75% + 40% per subject | Aggregate and per subject | 65%, then never |
| VTU 2021 | 75% | Per course | 70% (5% condonable) |
| Anna 2023 | 75% | Per course | Medical exclusion only |
Why the recovery number surprises people
The arithmetic of attendance is unforgiving in one direction. Missing classes drops your percentage quickly; attending classes raises it slowly, because every class you attend also increases the denominator.
A worked example. You have attended 40 of 60 classes — that is 66.67%. To reach 75%, you cannot simply attend “a few more”. If you attend the next n classes without missing any, you need (40 + n) ÷ (60 + n) ≥ 0.75, which resolves to n ≥ 20.
Twenty consecutive classes, with no absences, to move from 66.67% to 75%. That is the number students consistently underestimate, and it is why the useful moment to check is the middle of the semester rather than the end of it.
The attendance calculator does both directions — how many you can still miss, and how many consecutive classes it takes to recover — using your university’s own required percentage and condonation floor.
What to do if you are already below
Three things, in order.
Find out which band you are in. Above the floor and below the requirement, you have an application to make. Below the floor, no application exists, and the sooner you know that the sooner you can plan around a detained semester rather than hoping.
Apply immediately, not at the end. Condonation is granted on genuine grounds with supporting evidence. Evidence assembled in the week before exams looks like what it is. Medical documentation in particular usually has a submission window attached.
Work out what a detained semester actually costs you. If you are heading for a shortfall, the knock-on effect is credits, and credits are what promotion depends on. The promotion calculator shows whether you clear your year’s credit threshold, and the backlog planner works out the fewest subjects you would need to clear to close the gap.
Attendance and condonation questions
Is condonation guaranteed if I am above 65%?
No. Every regulation quoted here describes it as something that may be granted on genuine and valid grounds, with supporting evidence, by a specific authority. Being inside the band makes you eligible to apply. It does not make the outcome certain, and it usually carries a fee.
Does medical leave count as attendance?
It is not automatically counted as attended. What the regulations provide is a route to have specific absences excluded or condoned on documented medical grounds, and that route has a submission window. Anna University’s rule is explicitly framed as a medical-emergency exclusion rather than a general condonation.
My overall attendance is fine but one subject is low. Am I safe?
That depends entirely on your university. JNTUH measures in aggregate. VTU and Anna measure per course, so one weak subject is a problem on its own. JNTUK measures the aggregate but also sets a 40% minimum in each individual subject. Check which basis applies to you before relying on an overall figure.
How many classes can I miss and stay at 75%?
It depends on how many have been held so far, because every class held changes the denominator. Enter your figures into the attendance calculator — it also tells you the recovery number, which is the one people get wrong.
Can attendance shortage be condoned twice?
The regulations quoted here describe condonation per semester rather than granting a running allowance. Where a limit on repeated condonation applies, it is set by your college’s academic committee. Ask your department rather than assuming a second application will be treated like the first.
Where this comes from
Every figure above is read from the issuing university’s own published regulations: JNTUH R22 clauses 6.1, 6.2 and 6.4 and R25 clauses 7.1, 7.2 and 7.5; JNTUK R23 clause 17; VTU 2021 clause 21OB5.1; and Anna University Regulation 2023 clauses 11.1, 11.2 and 11.4. The clause number is given beside each so you can check it against your own copy.
Nothing here was taken from another calculator site or a forum thread. If your regulation says something different from what is written above, tell me — on this subject one wrong number is worse than no page at all.
