For high school teams:
| Period | Length |
|---|---|
| Quarters | Four of 8 minutes |
| Between quarters 1-2 and 3-4 | 1 minute |
| Halftime | 10 minutes (may be extended to a maximum of 15 minutes with proper notification) |
| Overtime | 4 minutes, with a 1-minute intermission before each |
- Overtime is played without changing baskets, and as many extra periods as needed are played until the tie is broken.
- Extra periods are an extension of the fourth quarter (so fourth-quarter team fouls carry over).
- For teams younger than high school age, quarters are 6 minutes. Non-varsity overtime is half the length of a regulation quarter.
