The problem
Schools spend 8+ hours each term on a problem that should only take 30 minutes.
Every term, schools must allocate specialist subject lessons against DOTT entitlements. This results in a complex constraint problem balancing part-time and job-share staff, fortnightly rotations, varying teaching block durations, split classes, year group common DOTT alignments, blocked periods, subject load caps, and many more.
It is the kind of problem a spreadsheet cannot reliably solve without frequent DOTT deficits. Most schools get close enough, teachers absorb the errors, and the process is repeated the next term.
The solution
Built for primary schools.
Dotti builds fair, balanced DOTT timetables for Australian primary schools in minutes. It's a constraint solver that truly understands the unique complexities of a primary school context.
"Dotti has completely transformed how we build our timetable. It is incredibly well thought out and clearly designed by someone who genuinely understands the realities of primary school timetabling. What used to take days of juggling schedules, making compromises and manually adjusting countless variables can now be achieved in a fraction of the time. I can't imagine going back to doing it manually."Mark WaltersPrincipal, Floreat Park Primary School

How it works
Common DOTT you can see at a glance
Dotti returns one whole-school table showing every class, every block, with aligned cohorts colour-coded. You see exactly where a year group is released together, and where it isn't.
An interactive editor, not a locked-in result
Move a lesson, swap another, or park one aside to place later. Reassign cover to a different teacher. Lock the parts you're happy with and let Dotti re-optimise everything else around it. You know things the solver can't.
A DOTT summary that stands up to scrutiny
One row per teacher: FTE, entitled minutes, what the timetable actually delivered, and the difference — surplus, spot on, or deficit. It updates as you edit and exports to Excel.
A clean timetable for every class
Each class gets its own weekly timetable: subject, teacher, and DOTT clearly marked, sessions kept whole, shared classes named. Read-only by design — the copy you hand to a teacher or pin on the wall.
Features
The details that make each run smoothly.
Every constraint you wrestle with manually — solved in minutes.
Per-teacher entitlements
Set each individual teacher's entitlement and get instant feedback on any surplus or deficit.
Address real school complexities
Allow split classes, class-share, part-time and multi-role teachers. Create fortnightly rotations and varying teaching block durations. Block out any specific slots on specific days, e.g. for assemblies.
Customise your teacher's day
Specify a cap on specialist subjects per day. Run DOTT periods back-to-back on the same day or group them together. Pin a specialist teacher/subject to a specific day or slot.
Compare your options
Where genuinely different timetables exist, Dotti returns up to five, each scored, so you can choose.
Export to Excel
Download key timetables and summary page as excel workbooks.
Save, clone, re-run
Set up your school once. Each term, clone or tweak the inputs and re-solve.
The benefit
DOTT release that's fair.
Dotti scales every teacher's DOTT entitlement to their FTE, so part-time and job-share allocations come out right without the manual arithmetic. Where a year group shares release time, it aligns so the whole cohort is covered at once.
In the field
Built with schools, not just for them.
Dotti is shaped in staffrooms and school libraries, alongside the (deputy) principals who actually build the timetable. Every feature traces back to a problem someone was already living with.
