Side by side
| Question | Spreadsheet | Scheduling tool |
|---|---|---|
| Setup | A grid you already know how to build | Enter your week, class blocks and students once |
| Finding a time | You scan the grid and every teacher's timetable by eye | Every legal time is found for each student |
| Class blocks and lunch | Checked by memory | Never blocks are never used; avoid blocks only when nothing else fits |
| Never-group pairs and group size | Checked by memory | Enforced in every session |
| Minutes met | A formula you maintain | Scheduled against required for every student, per week or per month |
| A change in January | Redo by hand, hoping nothing breaks | Change the data and rebuild, or move one session with live checks |
| Who could not fit, and why | You find out when a teacher asks | Listed with the reason |
| Student data | Often full names in a shared drive | Initials only, kept in your browser |
Where spreadsheets break
The grid itself is not the hard part. The hard part is everything the grid does not know: that Room 9 has specials at 2:00 on Mondays, Wednesdays and Fridays only; that two students in Room 4 must never share a session; that one student's 20 minute sessions cannot join a 30 minute group; that a monthly 240 is a weekly 60. In a spreadsheet those rules live in your head, so every change means checking them all again. ASHA's caseload guidance (last reviewed 26 September 2026) reports a median school caseload of 48 students, which is a lot of rules to hold in your head.
Worked example: one change in January
A second grade teacher moves math to 10:00. In a spreadsheet, you find every student in that room, check each of their sessions against the new block, find new times that also suit their groups' other members, their other classrooms and your own meetings, and recheck everyone's minutes. In a scheduler, you change the one block and rebuild, or keep the week and look at the sessions now marked in red with the rule named. Either way the minutes report tells you whether anyone is now short.
When a spreadsheet is still the right call
- Fewer than about ten students, one building, and no grouping restrictions.
- A schedule that is set by the school, where you only record it.
- Tracking attendance and notes, which a scheduler does not do.
Common mistakes
- Keeping full student names in a shared spreadsheet when initials would do.
- A minutes formula that silently stops counting a row after a copy and paste.
- Color coding as the only record of a never-group rule.
- Choosing a tool that needs student records uploaded to someone else's server.
Where MinuteGrid fits
MinuteGrid is a free scheduler that runs in your browser: initials only, no account, nothing uploaded. It builds the week, checks every rule, lists unplaced sessions with reasons, prints teacher and student sheets, and exports CSV for your spreadsheet. It does not track attendance or write notes.
