For teachers and principals building next year's classes

Balanced class lists, without uploading a single name

Paste your grade from a spreadsheet and add the rules you keep in your head: friend requests, pairs to keep apart, twins together. Any rule or request the builder cannot keep is named, with the reason.

Try a Move menu: it shows what each move would break. Nothing here is saved.

How it works

Paste the grade. One student per row: name, current class, and any of gender, reading and math bands 1 to 4, behaviour, English learner and support flags, and notes. A header row is read if there is one.
Set the classes. How many, a name and teacher for each, and a size cap.
Add the rules. Up to 3 ranked friend requests per student, keep-apart pairs, siblings together or apart, and teacher requests.
Build. Hard rules are never broken silently: any rule the builder cannot keep is named with the reason. Balance and friend requests are traded off, and every request that could not be met is listed with the reason.
Review and print. Move a student and the warnings update as you go. Lock the ones you are sure of and rebalance the rest. Print class lists, placement cards and the summary.

What you get

Lists you still decide: You know the children; the tool does not. It balances what you enter and shows its working. Every move is yours to make, with a warning if it breaks a rule.
Requests handled in the open: Every friend request met or not met, every keep-apart pair honoured, and a plain reason for each request that could not be kept, ready to show a parent or a principal.
Cards and lists that match: Class lists, placement cards, the principal summary and the requests not met sheet all come from the same placement, so nothing drifts when you move a student.

Student names never leave your browser.

A class list is children's names next to notes about reading, behaviour and support, so ClassSplit has no server to send them to. The balancing runs on this page, your grade is saved in this browser only, and there is no account and no upload. Keep a copy with the backup file whenever you like. We make no compliance claim about your school's data rules: this is a planning tool that keeps everything on your device.
