How to Divide Students Into Random Teams
Start with a random, near-equal grouping, then make the smallest disclosed adjustments needed for learning, safety and accessibility. Randomness prevents habitual grouping patterns, but it does not know student relationships, support needs or the skills required by the task.
Recommended process
- Choose team count or target size before shuffling.
- Remove absent students and accidental duplicates.
- Apply known separation or fixed-placement requirements.
- Review group sizes and explain any manual changes.
Worked example
For 23 students and five teams, a balanced result contains three teams of five and two teams of four. The teacher then moves one student for an accommodation and explains that the adjustment followed a pre-existing classroom need.
What to check before using the result
- Do not promise demographic or skill balance from randomness.
- Keep safeguarding constraints private.
- Recheck groups when attendance changes.
How the random step is handled
Random Picker Tools uses window.crypto.getRandomValues() for browser-based selection. Integer results use rejection sampling to avoid modulo bias, and complete list orders use a Fisher–Yates shuffle. This addresses the software selection step; the organizer still controls eligibility, duplicate rules, consent, accessibility and any legal requirements.
Privacy note
Normal picking and shuffling happen in the browser. Use initials or non-sensitive identifiers when possible, avoid storing unnecessary source data, and create a share link only when temporary server storage is appropriate for the people represented in the list.
