Constraint recipe
Team teaching assigns two or more teachers to one class in the same period. Every teacher on the lesson must be free at that time, and the class and room must be free too. Checking each teacher separately is not enough: you need the overlap window for the whole team. Part-time days make that window small.
Key takeaways
- Every required teacher must be free in the same period.
- Check overlap, not individual calendars alone.
- Count workload for each teacher on the shared lesson.
- Place team-taught lessons before flexible single-teacher lessons.
Why overlap is the bottleneck
One teacher may have twenty free periods while their co-teacher has fifteen, but the shared lesson may only fit in six where both are free. Part-time days and campus commitments shrink that overlap fast.
Team teaching is also a staffing decision: each teacher's weekly load should reflect the shared delivery.
What to verify in the master data
Confirm every co-teacher is attached to the lesson, not only the lead teacher. Check part-time working days, room requirements, and how each teacher's hours are counted.
The team teaching guide covers load accounting patterns.
What to do next
- List every lesson with more than one required teacher.
- Draw the overlap of available periods for the full team.
- Confirm the class and room are free in those overlap periods.
- Count the lesson in each teacher's workload using local rules.
- Place team-taught lessons before flexible single-teacher lessons.
- If no overlap exists, change staffing or relax a softer preference.
Common mistakes
- Checking each teacher's calendar separately
- Forgetting part-time non-working days on a co-teacher
- Listing only the lead teacher on the lesson record
Quick answers
Is team teaching a mandatory rule?
If the lesson must have every listed teacher, yes. The lesson is invalid if any required teacher is missing or double-booked.
Why does team teaching cause double-booking errors?
One lesson reserves several teachers. If any one is already assigned elsewhere at that time, the lesson clashes.
