The substitute problem nobody talks about

Substitute teachers walk into classrooms every day with no access to district platforms, poorly written plans, and no way to report back. Students lose a day. Teachers come back blind.

No platform access

Subs can't log into Google Classroom, Canvas, or the district SIS. They're locked out of the tools every other teacher uses.

Bad or missing plans

Many teachers leave vague instructions or nothing at all. The sub improvises. Students disengage. Learning stops.

No feedback loop

Teachers return with no idea what happened. Did students work? Were there issues? Sticky notes on the desk don't cut it.

How SubDesk works

Three steps. No district login. No training required.

1

Choose grade level and subject

Walk into any classroom. Open SubDesk on your phone or laptop. Select the grade and subject you're covering today. That's it.

K-2 3-5 6-8 9-12 Math ELA Science Social Studies
2

Direct students to activities

SubDesk serves age-appropriate, standards-aligned activities that students can work through independently. Display on the board or share a class link. Students stay engaged while you manage the room.

3

Send the teacher a report

At the end of the day, SubDesk compiles a structured report: which activities were used, how far students got, your notes on behavior or issues. Sent directly to the absent teacher's email. They come back informed.

Privacy-first by design

Built to meet K-12 privacy standards from day one. Not as an afterthought.

Every student deserves a productive day, even when their teacher is absent.

SubDesk exists because substitute teachers deserve real tools, students deserve real instruction, and teachers deserve to know what happened while they were gone.
