Swap a lesson – without going through the office
An internal marketplace where teachers can offer and accept lesson swaps. The timetabler approves, the system updates the schedule and notifies everyone. Bryk & Schneider (2002) show that relational trust between colleagues is one of the strongest predictors of school improvement — the swap marketplace operationalises exactly that trust.
Bytteflowet: udbud → match → godkendelse → besked.
Offer & accept
A teacher offers a lesson; colleagues see it in their own view and can accept.
The swap function the system
Atomic swap that checks conflicts, subject competence and absence before going through.
Weekday-bound swaps
Swaps are only suggested on dates that match the original weekday — no Monday/Friday mishaps.
Automatic fan-out
When a swap is approved, both teachers, the class's parents and the timetabler are notified.
Absent staff excluded
Anyone with approved absence on the date is not shown as a swap partner.
History & audit
Every swap is logged with initiator, acceptor, approver and timestamp.
Subject-competence check
Swaps between teachers without the required subject qualification are flagged as incomplete competence cover.
In the classroom
Teacher
Has a dentist appointment — offers the lesson and a colleague picks it up without office involvement.
Timetabler
Approves swaps in a single list instead of coordinating by email.
Parent
Gets a message when another teacher takes over — knows who their child meets.
For teachers and for school leadership
The marketplace shifts coordination away from the office and still gives leadership a full audit trail. Every swap is tied to an approver, and subject-competence flags appear before approval — so you know when a swap risks lowering instructional quality.
- Every approval is signed with timestamp and role
- Subject-competence flag per swap
- Parents are notified automatically — no 'who's our teacher now' emails
Offer a lesson from your own view, accept a colleague's in the same workflow. Swaps for weekdays you can't cover are honoured automatically, and no one can accept a swap on a day you have approved absence.
- No email threads — swaps happen in-app
- Your own availability windows are honoured
- History shows what you've swapped and with whom
Research base
The swap marketplace draws on research in collegial trust, teacher autonomy and the impact of stability in classroom leadership.
