when was the shot clock instituted in college basketball
Shot clock Since the 2015â€“16 season, all American college basketball uses a 30-second shot clock, while Canadian university basketball uses a 24-second clock. The American women's game has used a 30-second clock since the 1970s, but the men's game did not adopt a shot clock until 1985. The men's limit was originally 45 seconds, and was shortened to 35 seconds in 1993 before going to 30 seconds in 2015. The National Federation of State High School Associations (NFHS), which sets rules for high school basketball in the U.S., does not mandate the use of a shot clock, instead leaving the choice to use a clock and its duration up to each individual state association. Proposals to adopt a national shot clock for high school basketball have been voted down by the NFHS as recently as 2011.[22] Currently, eight U.S. states require the use of a shot clock of 30/35 seconds in high school competition: California, Maryland, Massachusetts, New York, North Dakota, Rhode Island, South Dakota, and Washington.[22]
Three-point field goal Used only in conference play for several years, it was adopted by the NCAA in April 1986 for the 1986–87 season at 19 ft 9 in (6.02 m)[24][25][26][27] and was first used in the NCAA Tournament in March 1987.[28] The NCAA adopted the three-pointer in women's basketball on an experimental basis for that season at the same distance, and made its use mandatory beginning in 1987–88.[29] In 2007, the NCAA lengthened the men's distance by a foot to 20 ft 9 in (6.32 m), effective with the 2008–09 season,[30] and the women's line was moved to match the men's in 2011–12.[29] American high schools, along with elementary and middle schools, adopted a 19 ft 9 in (6.02 m) line nationally in 1987, a year after the NCAA.[31] The NCAA used the FIBA three-point line (see below) in the National Invitation Tournament (NIT) in 2018.[32]
