How to Create Fair Random Teams for Classes and Events
Split a list of people into randomly balanced groups for classes, activities, games and events.
What to know before you start
Random assignment balances count, not skill, role, accessibility needs or other human constraints unless you handle those separately.
Recommended workflow
- Clean the participant list and decide the number of teams before generating.
- Generate once under the published rule, then only make transparent manual adjustments for real constraints such as accessibility or required roles.
- Avoid repeatedly rerolling until a preferred social outcome appears; that defeats the point of random assignment.
How to check the result
Recheck the result against the original input and the rule you intended to apply. Random assignment balances count, not skill, role, accessibility needs or other human constraints unless you handle those separately.
Common mistakes
Common failures come from wrong units, ambiguous assumptions, changing the rule after seeing a result, or using a quick browser workflow where a regulated or specialist process is required.
Frequently asked questions
Will all teams have the same size?
When the participant count is not divisible evenly, some teams will have one extra person.
Can I guarantee friends are separated?
Pure random grouping does not guarantee constraints. If separation or role balancing matters, use an explicit constrained grouping method.
