How the teaching load formula works
Schools express staffing as a mix of contracted hours, full-time equivalents (FTE), and scheduled teaching hours on the timetable. This calculator uses the same ratio planners put in staffing spreadsheets.
FTE share = scheduled teaching hours ÷ max teaching hours per full-time teacher
Example: if a full-time teacher may teach 24 hours per week and someone is scheduled for 18 hours, FTE share is 18 ÷ 24 = 0.75 (75%).
Overload means scheduled teaching hours are above the teacher's contracted hours. Underload means scheduled hours are below the contract. The contract line is what HR and union agreements usually reference; the full-time ceiling is what leadership uses for staffing models.
