SchoolDeck is built so a teacher’s recurring tasks take seconds, not minutes: attendance marked from a phone in under ninety seconds and working without signal, marks entered in a grid that behaves like a spreadsheet, and homework posted once to reach every parent in the section.
It does not deliver lessons or host content. Schools wanting courseware run a learning platform alongside it.
A teacher interacts with school software in the ninety seconds between a bell and a class settling. That constraint decides everything. Software that needs a laptop, a stable connection and four taps to mark a register does not get used — it gets done on paper and typed up on Saturday, which is how registers and the system stop matching.
So the design target is not features. It is the number of seconds and the number of taps, on a mid-range phone, in a corridor with one bar of signal.
Signal inside a school building is unreliable in a way that people who work in offices consistently underestimate. Ground-floor classrooms behind a staircase, labs with equipment, the far end of a corridor.
Attendance and marks entry therefore work with no connection at all and sync when one returns. The teacher is not told to try again later, because "try again later" means the register gets marked on paper and the day is lost.
Teachers enter marks in spreadsheets because spreadsheets are fast: arrow keys move, tab commits, a column can be pasted. Most school software replaces that with a form per student, which is roughly forty times slower and is the single most reliable way to make staff hate a system.
Teachers are not asked to re-enter anything the school already knows. A class list comes from the roll, a substitution comes from the timetable, a parent’s number comes from the admission record. Where a teacher is typing a thing that exists elsewhere in the school, that is a defect and we treat it as one.
And no remark is written on a teacher’s behalf. A generated comment published under a teacher’s name is a signature on someone else’s sentence, and a parent reading it reasonably believes a person wrote it.
Phrased the way they arrive, answered so each one stands on its own.
The later edit wins but the earlier one is not discarded — the audit trail keeps both, with who submitted what and when. Conflicts are surfaced rather than silently resolved.
Yes. There is no school-issued device requirement and no per-seat charge for staff — billing is per student, so every teacher having access costs nothing extra.
No. SchoolDeck is the record — attendance, marks, homework assignment, communication. Content delivery is a different job and we do not claim it.

Pricing is on the page, in the open, with the counting rule written next to it. Nobody has to book a call to find out what it costs.
