How to measure a teacher's performance without a strong batch hiding everything
Every owner knows who their good teachers are. Almost none can prove it. Here is a fair, three-part score you can run on a spreadsheet — or let software run for you.
The salary sheet makes your best teacher and your weakest teacher look identical. Board results don't help either: the teacher who was handed the strongest batch wins every year, whatever they did.
Start from what you can actually observe
Three things are visible every single day in a coaching centre. Did the teacher mark attendance on time? Did they update the syllabus plan? Did they enter marks the week the test happened? That's discipline — and it should be logged by the system, never self-reported.
Second: what do students say? A short review window each month, points-based, anonymous. Students are remarkably fair when the questions are about teaching, not about liking.
Third — and hardest — growth
Do not use the class average. Use three numbers: the class average (small weight), each student's growth against their own baseline from the first two months, and 'weak-lift' — how much the bottom third of the batch rose. A strong batch scores high on average but has nowhere to go on the other two.
Give a teacher the strongest batch and their growth score should barely move. If it jumps, your formula is measuring the batch, not the teacher.
Weight it, show it, repeat monthly
We use 30% discipline, 30% review, 40% growth, but the weights are yours. The important part is that every teacher sees their own score and rank within their wing every month — not once a year at appraisal. A score you can see is a score you can improve.
This is exactly the calculation Drishtaa runs automatically. You can move the weights yourself on the How it works page.
