How long is the high school shot clock?
NFHS rules allow state associations to use a 35-second shot clock. Not every state does, and some leagues use 30 seconds. Set the time to what your state association uses.
Many high school gyms have no shot clock hardware at all. A laptop on a TV or projector is enough to give players the same clock in practice that they see in games.
Which states are adding the shot clock, and when: high school shot clock by state.
All sports side by side: shot clock rules by sport.

How do you use a shot clock in high school practice?
Teams that play with a shot clock in some games and without it in others benefit most from practicing with one. Players learn to recognize when a possession is getting late.
Keep it running in scrimmages, and let a manager or assistant run it from their phone so the coach stays free.
Want reps on the clock? Drill mode in Pro runs the clock, the rest and the next rep for you. Ideas: shot clock drills.
Can you use it on match day?
Training is the default: free, with the times you choose. For games, match mode in Pro follows NFHS timing. The reset buttons become 35 (new possession). With the game clock on screen, the shot clock turns off when less game time than shot clock time remains.
Streaming the game? Put this shot clock in your stream with OBS, vMix, Streamlabs or YoloBox.
