Substitute coverage vs. duty coverage: they are not the same problem
Schools routinely assume their substitute system covers duties too. It almost never does, and the gap shows up at the crosswalk.
Two different jobs
Substitute placement fills a classroom period: it needs a credentialed external person, lesson plans, payroll, and often district-level approval. Duty coverage fills a 20-minute supervision post: it needs an internal colleague who is already in the building and free at 7:20 a.m.
- Substitute systems optimize for sourcing and compliance. Duty coverage optimizes for speed.
- Substitute placement is an approval workflow. Duty coverage should be a claim, not an approval.
- A sub filling a classroom does not inherit that teacher's carline post — and usually is not permitted to.
Where the gap opens
A teacher calls out. The sub system finds a classroom sub by 6:50. Nobody handles the fact that the same teacher had cafeteria duty at 11:40 and dismissal at 3:10. Those two posts stay silently empty until someone notices.
Running both cleanly
- 1Keep the substitute platform for classroom periods. It is good at that.
- 2Maintain duty posts in a separate roster that is visible to all internal staff.
- 3When an absence is entered, automatically surface that person's duty posts as open coverage.
- 4Let internal staff claim those posts in one tap, with no admin in the middle.
- 5Log every fill so the monthly review can show which absences left duties exposed.
The connecting step is step three. If absence entry and duty posting stay disconnected, the gap reopens every single time.
