Shot Clock in High School Basketball??

A long-time feature of College and Professional Basketball games might soon be found on the high school level.
The National Federation of High Schools last month approved a proposal for a
35-second shot clock on the high school level. The proposal allows state federations such as the Missouri State High School Athletic Association to adopt the proposal for teams in their state.
The proposal stated that each state association may adopt a shot clock beginning in the 2022-23 basketball season, to encourage standardization among states. A proposal for a national rule mandating a shot clock was not approved.
Guidelines include displaying two timepieces that are connected to a horn that is distinctive from the game clock horn and using an alternative timing device such as a stopwatch at the scorer’s table, for a shot clock malfunction.
