Question 1
What are the ideal dimensions for a high school basketball playing court?
A) 94 x 50 feet
B) 84 x 50 feet
C) 90 x 45 feet
D) 80 x 40 feet
E) 100 x 50 feet
Correct Answer: B) 84 x 50 feet
Rationale: According to IAABO and NFHS Rule 1, the ideal dimensions for a high school
court are 84 feet in length by 50 feet in width. While professional and collegiate courts are
94 feet long, the high school standard is 10 feet shorter to accommodate the age and
physical development of the players.
Question 2
During a 30-second timeout, where must cheerleaders remain?
A) On the end line under the basket
B) In the middle of the court for a performance
C) Outside the visual confines of the arena
D) Outside the playing area
E) Anywhere as long as they do not touch the players
Correct Answer: D) Outside the playing area
Rationale: To prevent interference with team huddles and the officials' ability to monitor
the floor, cheerleaders must remain outside the playing area during 30-second timeouts.
This ensures a clear path for players and coaches to communicate and for officials to
resume play promptly.
Question 3
What is the correct radius of the three-point line for high school basketball?
A) 20 feet 9 inches
B) 19 feet 9 inches
C) 21 feet 6 inches
D) 22 feet 1 inch
E) 18 feet 9 inches
Correct Answer: B) 19 feet 9 inches
Rationale: Rule 1-7 specifies that the radius of the three-point line is 19 feet 9 inches from
the point on the floor directly under the center of the basket to the outside edge of the arc.

The measurement of 20 feet 9 inches is a collegiate distance and is incorrect for high school
IAABO standards.
Question 4
How far do the marked free-throw lane spaces extend toward the sidelines?
A) 12 inches
B) 24 inches
C) 36 inches
D) 48 inches
E) 60 inches
Correct Answer: C) 36 inches
Rationale: The lane space marks are essential for organizing players during free-throw
attempts. These marks must extend 36 inches (3 feet) toward the sidelines to clearly define
the areas where non-shooters must remain until the ball is released.
Question 5
What is the required distance from the front plane of the backboard to the farther edge of the
free-throw line?
A) 12 feet
B) 15 feet
C) 18 feet
D) 10 feet
E) 14 feet
Correct Answer: B) 15 feet
Rationale: Standardized across almost all levels of basketball, the free-throw line is placed
so that its farther edge is exactly 15 feet from the front plane of the backboard. This
ensures a consistent degree of difficulty for the free-throw attempt.
Question 6
What is the purpose of the "X" placed on the floor in front of the official scorer?
A) To mark the center of the court
B) To designate the head coach’s standing area
C) To help substitutes properly report to the table
D) To indicate the jump ball location
E) To mark where the referee must stand during timeouts
Correct Answer: C) To help substitutes properly report to the table
Rationale: Placing an "X" out of bounds in front of the scorer facilitates the substitution
process. It provides a specific landmark for substitutes to stand at while waiting to be
beckoned onto the court, allowing the scorer to identify them easily.

Question 7
If a facility does not have a red or LED light behind the backboard, what must be used to indicate
time expiration?
A) The official's whistle
B) A hand signal from the timer
C) The audible timer's horn
D) A verbal count by the referee
E) A flashing scoreboard light
Correct Answer: C) The audible timer's horn
Rationale: In facilities lacking modern LED lighting integrated with the game clock, the
audible horn is the primary signal for the end of a quarter or extra period. The signal
signifies that time has expired, regardless of whether an official's whistle sounds
simultaneously.
Question 8
A ball dropped from six feet bounches back to a height of 52 inches. Is this ball properly inflated
according to the rules?
A) No, it must bounce at least 60 inches
B) Yes, the legal range is 49 to 54 inches
C) No, it must bounce between 55 and 58 inches
D) Yes, but only for girls' basketball
E) No, it is over-inflated
Correct Answer: B) Yes, the legal range is 49 to 54 inches
Rationale: Rule 1-12-3 states that a ball is properly inflated if, when dropped from 6 feet
onto the floor, it bounces back to a height of 49 to 54 inches (measured to the top of the
ball). Therefore, 52 inches is within the legal limit, and the official would be incorrect to
rule it improperly inflated.
Question 9
What is the standard measurement for the edge of the coaching box from the end line?
A) 14 feet
B) 21 feet
C) 28 feet
D) 35 feet
E) 42 feet
Correct Answer: C) 28 feet
Rationale: Unless a state association has specified otherwise, the standard distance for the
coaching box edge is 28 feet from the end line. This defines the restricted area in which a
head coach may stand and instruct their team.

Question 10
When is music and sound effects permitted to be played during a contest?
A) At any time the ball is live
B) Only during the first and third quarters
C) During pre-game, timeouts, intermissions, and post-game
D) Only when the visiting team has the ball
E) Never; music is banned in IAABO games
Correct Answer: C) During pre-game, timeouts, intermissions, and post-game
Rationale: Rule 1-18 states that music and sound effects must not interfere with the game
while the ball is live. They are restricted to dead-ball periods such as warm-ups, timeouts,
halftime/quarter intermissions, and after the game has concluded.
Question 11
Regarding jersey colors, what are the requirements for the home and visiting teams?
A) Home wears dark; Visitors wear white
B) Home wears white; Visitors wear contrasting dark
C) Both teams can wear the same color if agreed upon
D) Home must wear yellow; Visitors must wear blue
E) Colors do not matter as long as numbers are visible
Correct Answer: B) Home wears white; Visitors wear contrasting dark
Rationale: Rule 3-4-1 mandates that the home team shall wear white jerseys and the visiting
team shall wear a contrasting dark color. This clear distinction is necessary for officials,
scorers, and fans to distinguish between the two teams during play.
Question 12
Which of the following number combinations is illegal to have on the same team roster?
A) 1 and 2
B) 5 and 55
C) 0 and 00
D) 3 and 13
E) 24 and 42
Correct Answer: C) 0 and 00
Rationale: Under IAABO/NFHS rules, a team may not list both 0 and 00 on the roster for
the same game. While both are legal numbers individually, they are considered the same
number for the purpose of the scorebook and roster to prevent confusion in recording fouls
and points.
Question 13
A player in a white home uniform wears a white headband, white wristbands, white compression
