KL University TCBR Explained: Total Classes Before Registration
Understand what TCBR means in KL University NewERP, how pre-registration classes are deducted from your conducted count, and why your calculator percentage may differ from your ERP portal without TCBR mode enabled.
What is TCBR?
Total Classes Before Registration: sessions conducted before you were formally enrolled in a course.
Conducted − TCBR
NewERP subtracts TCBR from total conducted hours so you are evaluated only on classes held after registration.
TCBR Mode
Enable the TCBR toggle on the calculator dashboard to replicate official ERP calculations with zero discrepancy.
Why TCBR Exists in KL University NewERP
In many academic semesters, students add or change electives, transfer sections, or complete late course registrations after regular instructional periods have begun. When this occurs, earlier sessions for that course have already taken place without the student present.
Without an adjustment, those missed early sessions would register as unexcused absences, permanently depressing the student's attendance percentage. To solve this, KL University's NewERP records a TCBR (Total Classes Before Registration) value for each course component (Lecture, Tutorial, Practical, Skill).
How TCBR Is Applied to the Weighted LTPS Formula
When TCBR is recorded, the effective conducted count for each component is calculated by subtracting TCBR from the raw conducted count before multiplying by the LTPS component weight:
The ceiling function ceil() is applied to round up fractional percentages, exactly matching the university grading portal.
Before vs After TCBR Adjustment: Real Example
Consider a student who joined an engineering course late after 6 Lectures and 2 Labs had already been conducted (TCBR: L=6, P=2):
| Metric | Raw (Without TCBR) | Adjusted (With TCBR) | Difference |
|---|---|---|---|
| Conducted Lectures (L) | 26 | 26 − 6 = 20 | -6 lectures |
| Conducted Labs (P) | 10 | 10 − 2 = 8 | -2 labs |
| Attended Hours | 18 L, 8 P | 18 L, 8 P | Unchanged |
| Conducted Weight | 2,600 + 500 = 3,100 | 2,000 + 400 = 2,400 | -700 weight |
| Calculated Percentage | 71% (Detention Zone) | 92% (Safe Zone) | +21% |
Without TCBR deduction, the student appeared to be in detention danger (71%). With TCBR properly applied, their true attendance is 92% — safely above the 85% requirement.

Frequently Asked Questions: TCBR in KL University
What does TCBR stand for in KL University attendance?
TCBR stands for Total Classes Before Registration. It represents the number of instructional sessions conducted for a course before a student was officially registered or enrolled.
How does NewERP use TCBR in calculating attendance percentage?
KL University NewERP subtracts TCBR from total conducted classes for each component (L, T, P, S). The effective formula is: Attended / (Conducted - TCBR) * 100, applied using weighted LTPS values.
Why does my attendance look lower on the calculator than in NewERP?
If you were enrolled late, your total conducted count includes sessions you could not attend. Enabling TCBR mode in the KL Attendance Calculator subtracts those pre-registration classes, matching your official NewERP score.
Does TCBR mark a student absent for past classes?
No. TCBR classes are exempted from your denominator rather than marked as absences, ensuring late-registered students are not penalized for classes conducted before enrollment.
Where can I find my subject-wise TCBR values?
TCBR figures appear in the detailed course attendance breakdown inside the KL University NewERP portal (newerp.kluniversity.in) under the student attendance report.
