The Teacher Study Time Estimator converts course-delivery workload into a weekly preparation plan. It estimates hours for lesson planning, grading, feedback, and professional reading based on class count, teaching load, and adjustable time assumptions.
The tool is intended for workload planning, not a contractual staffing standard. Actual preparation needs vary with subject complexity, class size, assessment design, reusable materials, and institutional support.
1. Enter the teaching load
Add the number of classes and weekly contact hours for each class.
2. Set a preparation ratio
Estimate planning time required for every teaching hour.
3. Describe grading volume
Enter typical class size and weekly grading minutes per student.
4. Add professional reading
Include subject study, curriculum review, or development time.
5. Review weekly hours
Compare preparation, grading, and total workload before scheduling blocks.
Where:
Assumptions: Each class is assumed to use the same average load; meetings and administrative duties are excluded.
Together with 12 teaching hours, the modeled teaching workload is 34.0 hours before meetings and administration.
Results are estimates based on the values and assumptions entered.
Given:
4 classes, 3 teaching hours each, 0.6 prep hours per teaching hour, 24 students per class, 8 grading minutes per student, and 2 reading hours
Calculation:
Preparation = 4×3×0.6 = 7.2 hours. Grading = 4×24×8÷60 = 12.8 hours. Total study/preparation = 7.2+12.8+2 = 22.0 hours.
Result:
Estimated study and preparation time = 22.0 hours per week.
Interpretation:
Together with 12 teaching hours, the modeled teaching workload is 34.0 hours before meetings and administration.
Base it on recent weeks. New courses often require more preparation than courses with reusable materials.
Use the total average minutes per student for all work graded in a typical week.
This model uses one average. For materially different classes, run separate estimates and add the results.
It is not necessarily tied to contact hours or enrollment, so a fixed weekly input is clearer.
Not necessarily. Employment rules and workload agreements vary; the result is a personal planning estimate.
