Fewer teacher gaps
Reduce unnecessary waiting between lessons and target more compact working days.
Timetable quality
Completing the timetable is not enough. It needs to be good.
Dersiva does more than place lessons into empty cells. It evaluates teacher working patterns, students’ daily learning load and the school as a whole to target a more balanced and practical timetable.
Same completion · different quality
Two timetables can both be 100% complete, yet one can be clearly better.
Quality begins after lessons are placed. Gaps, daily intensity, short days, lesson distribution and school-wide fairness determine how usable the timetable is in everyday school life.
Dersiva quality model
Evaluate quality through interacting metrics, not a single score.
Improving one teacher’s timetable by unnecessarily damaging another teacher’s timetable is not quality. Dersiva targets school-wide balance.
Balanced daily intensity
Reduce both overloaded days and days that require coming to school for very few lessons.
Better lesson distribution
Protect blocks, weekly patterns and suitable lesson periods while distributing lessons more meaningfully.
Student learning load
Use lesson weight and suitable periods to consider students’ daily learning load as part of quality.
Teacher-specific limits
Make different daily maximums and working preferences part of the quality model.
School-wide fairness
Evaluate quality across all teachers instead of optimizing only a small group.
Teacher gaps
Spend less time waiting and more time in compact working days.
A timetable may be technically complete while forcing teachers to wait for hours between lessons. Dersiva treats the reduction of unnecessary gaps as a core quality objective.
- ✓Reduce unnecessary waiting during the day
- ✓Track gaps school-wide rather than for one teacher only
- ✓Compact lessons without excessive compression
Dense and short days
Avoid both overload and unnecessarily short days.
Too many lessons on one day can be exhausting, while coming to school for one or two lessons can be inefficient. Dersiva works between these two extremes.
- ✓Teacher-specific daily lesson maximums
- ✓Short-day penalty structure
- ✓Distribute weekly workload more evenly
Lesson weight and student focus
Place lessons not only in a free period, but in a suitable period.
Lesson weight and the student’s daily learning load are part of timetable quality. More demanding lessons can be steered toward suitable periods while the composition of the day remains balanced.
- ✓Scheduling by lesson weight
- ✓Reduce unnecessary placement of demanding lessons late in the day
- ✓Evaluate the student’s daily lesson load together
School-wide fairness
Improve one timetable without sacrificing another.
Quality is not a small group of teachers receiving excellent timetables. Dersiva targets a fairer approach that considers the impact of improvements across the school.
- ✓Quality distribution among teachers
- ✓Reduce the gap between extremely good and extremely poor timetables
- ✓Balance personal preferences with school-wide needs
Duty and teaching intensity
Treat the duty day as part of the real workload.
When duty is selected automatically, teaching intensity and capacity can be considered together. If administrators select the duty day, the timetable can still account for that day’s real load.
- ✓Evaluate duty day and teaching intensity together
- ✓Respect the teacher’s daily capacity
- ✓Keep duty-exempt teachers outside the duty pool
Bottlenecks and explainability
When quality drops, understand why.
The barrier to a better timetable may come from the combination of capacity, unavailable days, class periods or teacher constraints. Dersiva aims to make those pressure points visible.
- ✓Show unplaced lessons and pressure points
- ✓Separate teacher and class bottlenecks
- ✓Compare trial timetables by quality
Comparable quality
Compare trial timetables with quality metrics, not only “worked / did not work.”
Different trials generated from the same data can be evaluated through gaps, balance, short days, distribution and other indicators, making the choice of applied timetable more deliberate.
Aim for a better timetable
Choose the timetable that is practical at school, not merely complete.
