Placement Rules & Constraints

Real schools have real requirements. Define exactly which students must — or must not — share a classroom, and set hard limits on class composition.

Keep-together pairs — ensure specific students are in the same class
Keep-apart pairs — prevent specific students from sharing a class
Assign-to-class — force specific students into a designated class
Maximum students per class — set capacity limits
Gender difference cap — control maximum gender imbalance per class
Attention limit — cap students needing extra attention per class

Analytics & Insights

See the big picture at a glance. Visual dashboards and per-class breakdowns show you exactly how balanced your assignments are before you finalize them.

Per-class statistics showing gender ratio and attribute averages
Friends stats — percentage of students with 1+ and 2+ friends in their class
