Texas is set to become the 36th state to adopt a shot clock for high school basketball following a new approval from the University Interscholastic League. Classes 5A and 6A will be required to utilize a 35-second shot clock beginning in 2028.

University Interscholastic League

This organization serves as the governing body for extracurricular activities for public primary and secondary schools in Texas.

The details

Schools will need to designate an adult operator for the shot clock in addition to maintaining a standard scorebook for games. While large schools face mandatory deadlines, smaller schools retain the option to begin using the equipment in later years.

October 19, 2026: University Interscholastic League council approved the new shot clock rule.
2027-28 school year: Optional implementation begins for Classes 5A and 6A.
2028-29 school year: Mandatory implementation takes effect for Classes 5A and 6A.
2030-31 school year: Optional implementation begins for Classes 3A and 4A.
2032-33 school year: Optional implementation begins for Classes 1A and 2A.

Season Trajectory

The adoption of the shot clock shifts Texas high school basketball toward the pace and tactical style used in collegiate and professional leagues. This rule change follows the pattern set by 35 other states that have already integrated shot clocks into their high school programs.

The rule mandates that Classes 5A and 6A schools secure funding and personnel for clock operations by the 2028-29 season. Future seasons will see smaller classifications adopt the technology on an optional basis, affecting how local teams prepare for game-day pacing.

The takeaway

The move to a 35-second shot clock signals a major transition in the style of play for Texas student-athletes. Schools should begin planning for the $4,500 equipment cost and staffing requirements well in advance of their designated implementation year.
