Section VII-Duties of Scorers

a. The scorers shall record the field goals made, the free throws made and missed and shall keep a running summary of the points scored. They shall record the personal and technical fouls called on each player and shall notify the officials immediately when a sixth personal foul is called on any player. They shall record the timeouts charged to each team, shall notify a team and its coach through an official whenever that team takes a sixth charged timeout and shall notify the nearest official each time a team is granted a charged timeout in excess of the legal number. In case there is a question about an error in the scoring, the scorer shall check with the crew chief at once to find the discrepancy. If the error cannot be found, the official shall accept the record of the official scorer, unless he has knowledge that forces him to decide otherwise.
b. The scorers shall keep a record of the names, numbers and positions of the players who are to start the game and of all substitutes who enter the game. When there is an infraction of the rules pertaining to submission of the lineup, substitutions or numbers of players, they shall notify the nearest official immediately if the ball is dead, or as soon as it becomes dead if it is in play when the infraction is discovered. The scorer shall mark the time at which players are disqualified by reason of receiving six personal fouls, so that it may be easy to ascertain the order in which the players are eligible to go back into the game in accordance with Rule 3-Section I.
c. The scorers shall use a horn or other device unlike that used by the officials or timers to signal the officials. This may be used when the ball is dead or in certain specified situations when the ball is in control of a given team.
d. When a player is disqualified from the game, or whenever a penalty free throw is being awarded, a buzzer, siren or some other clearly audible sound must be used by the scorer or timer to notify the game officials. It is the duty of the score-keeper to be certain the officials have acknowledged the sixth personal foul buzzer and the penalty shot buzzer.
e. The scorer shall not signal the officials while the ball is in play, except to notify them of the necessity to correct an error.
f. Should the scorer sound the horn while the ball is in play, it shall be ignored by the players on the court. The officials must use their judgment in stopping play to consult with the scorer's table.
g. Scorers shall record on the scoreboard the number of team fouls up to a total of five, which will indicate that the team is in a penalty situation.
h. Scorers shall, immediately, record the name of the team which secures the first possession of the game.
Section VIII-Duties of Timers
a. The timers shall note when each half is to start and shall notify the crew chief and both coaches five minutes before this time, or cause them to be notified at least five minutes before the half is to start. They shall signal the scorers two minutes before starting time. They shall record playing time and time of stoppages as provided in the rules. The official timer and the 24-second clock operator shall be provided with digital stop watches to be used with the timing of timeouts and in case the official game clock, 24-second clocks/game clocks located above the backboards fail to work properly.
b. At the beginning of the first period, any overtime period or whenever play is resumed by a jump ball, the game clock shall be started when the ball is legally tapped by either of the jumpers. No time will be removed from the game clock and/or 24-second clock if there is an illegal tap.
c. If the game clock has been stopped for a violation, successful field goal or free throw attempt and the ball is put in play by a throw-in, the game clock and the 24-second clock shall be started when the ball is legally touched by any player on the court. The starting of the game clock and the 24-second clock will be under the control of the official timer.
d. During an unsuccessful free throw attempt, the game clock will be started when the ball is legally touched. The 24-second clock will be reset when player possession of the ball is obtained.
e. The game clock shall be stopped at the expiration of time for each period and when an official signals timeout. For a charged timeout, the timer shall start a digital stop watch and shall signal the official when it is time to resume play.
f. The game clock and the scoreboard will combine to cause a horn to sound, automatically, when playing time for the period has expired. If the horn or buzzer fails to sound, or is not heard, the official timer shall use any other means to notify the officials immediately. If, in the meantime, a successful field goal has been attempted or a personal foul has occurred, the Crew Chief shall consult his fellow officials and the official timer. If the official timer states that time expired before the field goal attempt left the player's hand(s), the field goal shall not count. If the official timer states that time expired before the personal foul occurred, the personal foul shall be disregarded, unless it was unsportsmanlike. If there is a disagreement between the officials and the official timer, the field goal shall count and the personal foul shall be penalized unless the officials have other personal knowledge.
g. In a dead ball situation, if the clock shows :00.0, the period or game is considered to have ended although the horn may not have sounded.
h. Record only the actual playing time in the last minute of the first, second and third periods.
i. Record only the actual playing time in the last two minutes of the fourth period and the last two minutes of any overtime period(s).
