School Structural KPI Tool
Structural KPI Reference and School Capacity Simulator
Explore the four structural KPIs school leaders use to judge staffing balance, room pressure, and operating slack. Switch presets, model your structure, and review a deterministic correction plan instantly.
Use this view to understand what each KPI means before you simulate scenarios.
Pedagogical and financial
The total number of enrolled students divided by the total number of teaching staff. It estimates the average student load each teacher must absorb.
Total students / total teachers
15 to 20 students per teacher in a balanced whole-school model.
A low ratio usually means stronger individual attention, but it can also reveal oversized staffing relative to enrollment.
A high ratio reduces teacher attention per learner, raises workload pressure, and makes quality drift more likely.
Review this KPI by grade band, then decide whether the issue is recruitment, group redesign, or student distribution across the current team.
