Example data table

Sample scenarios to illustrate how totals change with assumptions.
Scenario Students Unique preps Assignments / student Meetings (h) Estimated total (h)
Elementary (fewer graded artifacts) 25 1 0.8 1.5 ~34–40
Middle school (moderate grading) 120 2 1.5 2.0 ~44–52
Secondary (heavy grading + clubs) 150 3 2.0 3.0 ~55–65

Formula used

All minutes are converted into hours by dividing by 60.
InstructionHours = Days × PeriodsPerDay × PeriodLengthMin ÷ 60
EmbeddedPlanningHours = PrepPeriodsPerWeek × PeriodLengthMin ÷ 60
PlanningDemand = (UniquePreps × PlanningMinPerPrep ÷ 60) × Intensity + (InstructionHours × 0.12)
PlanningHours = max(0, PlanningDemand − EmbeddedPlanningHours)
WeeklyAssignmentGrading = Students × AssignmentsPerStudentWeek × MinutesPerAssignment ÷ 60
WeeklyMajorGrading = Students × MajorPerMonth × MinutesPerMajor ÷ 60 ÷ 4.33
WeeklyFeedback = Students × FeedbackMinPerStudentWeek ÷ 60
TotalHours = sum of all workload categories
WorkloadRatio = TotalHours ÷ ContractHours
The 4.33 factor converts “per month” into a weekly average. The 0.12 term adds a small planning overhead per instruction hour.

FAQs

1) What does the workload ratio mean?

It compares your estimated weekly hours to your contract hours. A ratio above 1.00 suggests you are working beyond contracted time, on average.

2) Why do prep periods reduce planning hours?

Prep periods represent planning time already built into the school day. The model subtracts that “embedded” time from planning demand to estimate after-hours work.

3) How should I estimate grading minutes?

Time one typical sample, then use the average. Include setup, rubric use, feedback, and recording marks. If you batch-grade, use a lower per-item minute estimate.

4) What if my workload changes weekly?

Use averages across a month. For peak periods, increase major assessments and meetings. Saving CSV reports helps you compare a normal week to a busy one.

5) Does it include break times or lunch?

This tool focuses on task time. If you want a stricter estimate, add lunch supervision, extra duty, or commuting into the “duty” and “extracurricular” fields.

6) How can I lower a “High load” result?

Start with the biggest categories. Reduce grading frequency, use rubrics, reuse lessons, co-plan, set communication windows, and renegotiate extra duties during peak seasons.

7) Is this suitable for team teaching or shared classes?

Yes. Adjust students, assignments, and planning minutes to reflect your share of the work. If planning is shared, choose “Low” intensity or reduce minutes per prep.

8) Why are major assessments averaged across weeks?

Major grading often happens in bursts. Spreading monthly counts over 4.33 weeks provides a realistic weekly average so totals are comparable across different months.
