📖 1. Basketball court and floor dimensions

🔑 Key Concepts & Definitions

• Basketball court : The court is the playing surface with a flat, hard finish and fixed boundary lines that define the game area.
• Court dimensions : Court dimensions are measured from the inner edge of the boundary line and set the official length and width of the playing area.
• Floor boundary lane : The floor includes an outer boundary lane around the court that provides extra space beyond the playing surface.
• Backcourt : A team’s backcourt is the area from its own basket endline to the centre line, including the inbounds part of the backboard.
• Frontcourt : A team’s frontcourt is the area from the opponents’ basket endline to the inner edge of the centre line nearest the opponents’ basket.

📝 Essential Points

• The court must be flat and hard, free from obstructions, with dimensions 28 m long by 15 m wide measured from the inner edge of the boundary line.
• The floor must include a boundary lane free from obstructions with minimum width 2 m, giving minimum floor dimensions 32 m by 19 m.
• The boundary line (endlines and sidelines) limits the court, and these lines are not part of the court area.
• A team’s backcourt includes its own basket, the inbounds part of the backboard, and the court area limited by its endline, sidelines, and the centre line.
• A team’s frontcourt includes the opponents’ basket, the inbounds part of the backboard, and the court area limited by the opponents’ endline, sidelines, and the inner edge of the centre line nearest the opponents’ basket

💡 Memory Hook

Court is 28×15; add 2 m all around to get floor 32×19 (court + 4 m each dimension).

📖 2. Backcourt and frontcourt definitions

🔑 Key Concepts & Definitions

• Backcourt : Backcourt is the half-court area of a team that includes the basket it is defending and the space behind the centre line.
• Frontcourt : Frontcourt is the half-court area of a team that includes the basket it is attacking and the space beyond the centre line.
• Centre line : The centre line is the line that separates a team’s backcourt from its frontcourt.
• 3-point line : The 3-point line is a boundary line on the court that helps define legal player locations for rules that depend on where a player is.
• Free-throw line : The free-throw line is the line used for free throws and also affects player location status when determining where a player is on the court.

📝 Essential Points

• A player’s location is determined by where they are touching the floor, and the same location status applies while they are airborne.
• A player’s location includes boundary line, centre line, 3-point line, free-throw line, restricted-area lines, and the no-charge semi-circle lines.
• A referee’s location is determined the same way as a player’s, and when the ball touches the referee it is treated as touching the floor at the referee’s location.
• Backcourt/frontcourt distinctions matter because some rules depend on whether the ball or a player is in a particular half of the court.
• When a rule refers to a player’s location, use the last floor-contact point if the player is airborne.

💡 Memory Hook

Centre line = divider: behind it is backcourt, beyond it is frontcourt; airborne keeps the last floor-contact status.

📖 3. Court lines and boundary line rules

🔑 Key Concepts & Definitions

• Boundary line : A boundary line is the court’s limit that separates in-bounds space from out-of-bounds space.
• Out-of-bounds player : An out-of-bounds player is one whose body contact is with the floor or an object other than a player while that contact is on or outside the boundary line.
• Out-of-bounds ball : An out-of-bounds ball is a live ball that touches a player or person who is out-of-bounds, or touches the floor or objects on or outside the boundary line, or touches backboard supports/back of backboards or objects over
• Jump ball situation : A jump ball situation is the restart that occurs when a player moves out-of-bounds or to the player’s backcourt during a held ball.

📝 Essential Points

• A violation of the boundary line rules results in the ball being awarded to the opponents for a throw-in from the nearest spot to the infraction, except directly behind the backboard.
• A player is out-of-bounds if any part of the body is in contact with the floor or any object other than a player while that contact is on or outside the boundary line.
• The ball is out-of-bounds if it touches a player/person who is out-of-bounds.
• The ball is out-of-bounds if it touches the floor or any object above, on, or outside the boundary line.
• The ball is out-of-bounds if it touches the backboard supports, the back of the backboard, or any object above the court.
• The ball is caused out-of-bounds by the last player to touch or be touched by the ball before it goes out-of-bounds, even if it then goes out by touching something else.

💡 Memory Hook

Out-of-bounds = last touch decides: last player touch before the ball crosses the line (or backboard/supports) determines who caused it.

📖 4. Centre line, centre circle and free-throw semi-circles

🔑 Key Concepts & Definitions

• Centre line : A court marking that separates the backcourt and frontcourt for positioning and restart procedures.
• Centre circle : The circular marking at midcourt used for the start-of-game and certain jump-ball restarts.
• Free-throw semi-circles : The arc-shaped areas on each end of the court that define where players may be positioned during free throws.
• Restricted area : The key area near the basket that limits how long offensive players may stay without a shot.

📝 Essential Points

• The restricted area is the opponents’ restricted area for the 3-second rule.
• A player may not remain in the opponents’ restricted area for more than 3 consecutive seconds while their team controls the ball in the frontcourt and the game clock runs.
• Allowances exist for a player attempting to leave the restricted area, for players in the restricted area during a shot leaving the hand(s), and for dribbling there to shoot after being there for <3 consecutive seconds.
• To be established outside the restricted area, both feet must be placed on the court outside the restricted area.
• The centre line is used for throw-ins at the start of other quarters (shot clock procedure references throw-ins from the centre line).
• After a jump ball at the start of the first quarter or after a throw-in from the centre line at the start of other quarters or each overtime, the shot clock starts at 24 seconds.

💡 Memory Hook

3-second rule = “3 in the paint”: stay in the restricted area >3 straight seconds while clock runs and you’re in frontcourt control.

📖 5. Free-throw lines, restricted areas and rebound places

🔑 Key Concepts & Definitions

• No-charge semi-circle : A marked lane under the basket used to judge charge/block contact during offensive penetration.
• Restricted area : The area under the basket that defines where the cylinder principle is applied for certain contact interpretations.
• Rebound places : Designated court spots that govern where players may be positioned for rebounds after a free throw or similar restart.
• Cylinder principle : A rule that lets each player occupy an imaginary vertical space on the court not already taken by an opponent.

📝 Essential Points

• No-charge semi-circle contact by an airborne offensive player is not a team control foul unless the offense uses illegal hands, arms, legs, or body.
• The no-charge semi-circle rule applies when the offensive player is controlling the ball while airborne and attempts a shot or pass.
• The defensive player must have one or both feet touching the no-charge semi-circle area for the no-charge semi-circle protection to apply.
• When contact occurs in the no-charge semi-circle under these conditions, referees treat it as not a team control foul (subject to the illegal-use exception).
• The cylinder principle protects the space a player occupies and the space above when jumping vertically within that space.
• If a player leaves the vertical position and contact occurs with an opponent who had already established that vertical position, the leaver is responsible for the contact.

💡 Memory Hook

No-charge = Airborne offense + ball control + shot/pass + defender’s foot in the semi-circle → no team control foul (unless illegal body/hand use).

📖 6. Three-point goal area and team bench areas

🔑 Key Concepts & Definitions

• Three-point goal area : A named court area used to determine whether a made basket scores 2 or 3 points.
• Team bench area : A designated area where eligible team personnel sit and where certain conduct rules apply during the game.
• Throw-in line : A specific line on the court used to restart play with a throw-in after certain penalties.
• Centre circle : The court circle used for a jump ball restart at the start of the first quarter.

📝 Essential Points

• A throw-in after an unsportsmanlike foul is taken from the throw-in line in the team’s frontcourt, opposite the scorer’s table.
• After an unsportsmanlike foul, a jump ball is held in the centre circle at the start of the first quarter.
• A throw-in after a disqualifying foul is taken from the throw-in line in the team’s frontcourt, opposite the scorer’s table.
• A jump ball after a disqualifying foul is held in the centre circle at the start of the first quarter.
• Players or permitted bench persons must not make physical actions that could damage game equipment; the head coach is warned and repeat actions lead to technical or disqualifying fouls.
• Disqualified persons must leave the game immediately (≤30 seconds) and go to the team dressing room for the rest of the game or leave the building.

💡 Memory Hook

3-point area sets 3 points; bench area controls conduct—fouls restart with throw-in line or centre-circle jump ball.

📖 7. Throw-in lines and no-charge semi-circle areas

🔑 Key Concepts & Definitions

• Throw-in line extended : A throw-in location line used to restart play after certain free-throw errors, placing the ball for the opponents.
• Place nearest where stopped : The restart spot chosen after correcting an error, meaning the game resumes from the closest point to where play was interrupted.
• No-charge semi-circle : A restricted area near the basket where charging is limited, affecting how contact can be judged.
• Throw-in after correction : A restart that occurs after referees correct an error, with the ball awarded and play resumed using the specified restart location.

📝 Essential Points

• If a merited free throw is missed due to an error and possession has not changed, play resumes after the correction as after the last free throw.
• If the same team scores after being erroneously awarded possession for a throw-in, the throw-in possession error is disregarded.
• If the game clock has started and there is a change of possession, after correction the game resumes from the place nearest to where it was stopped to correct the error.
• When the wrong player is allowed to attempt free throws, those attempts are cancelled and opponents get a throw-in from the free-throw line extended unless the game already continued and was stopped for correction.
• When the wrong player is directed to attempt free throws, the attempted free throws are cancelled and the correct player takes replacement free throws, with restart rules depending on whether play continued for the error
• When points are erroneously awarded or cancelled, the scoresheet is corrected and the game resumes from the place nearest to where it was stopped to correct the error.

💡 Memory Hook

Error correction = “nearest stop” restart; wrong free-throw taker → opponents throw-in from extended line; wrong free-throw direction → replacement free throws.

📖 8. Required basketball equipment list

🔑 Key Concepts & Definitions

• Official basketball : A regulation ball used for play that must meet the competition’s official specifications.
• Basketball hoop : A regulation basket structure with a rim and net that defines the scoring target.
• Backboard : A regulation board mounted behind the hoop that supports the basket and is part of the scoring equipment.
• Court markings : The painted or marked lines and zones on the playing surface that define boundaries and key areas.
• Game clock : A timing device used to track the official duration of play and periods.

📝 Essential Points

• The required equipment list is not provided in the supplied material, so no specific items can be extracted for an exam-ready list.
• The excerpt shown focuses on referees’ signals and scoresheet administration, not on equipment requirements.
• No ball specifications, hoop dimensions, backboard measurements, or court measurement standards appear in the provided text.
• No list of table equipment (e.g., shot clock, timer, scorer tools) is explicitly stated as “required” in the excerpt.
• Because the source does not contain the equipment list, any attempt to name items would risk inventing facts not present in the material.

📖 9. Team eligibility and players injury assistance

🔑 Key Concepts & Definitions

• Eligibility rules : Eligibility rules are the competition requirements that players and teams must satisfy to be allowed to participate.
• Protest procedure : Protest procedure is the formal process a team must follow to challenge an outcome affecting its interests.
• Competent body : Competent body is the authority that receives protest documents and issues an immediate decision using reliable evidence.
• Field of play rule decision : Field of play rule decision is a ruling treated as final for further review or appeal, except for eligibility appeals under regulations.

📝 Essential Points

• A team may file a protest when its interests are harmed by an error in scorekeeping, timekeeping, or shot clock operations that referees could correct but did not.
• A protest may also be filed for decisions to forfeit, cancel, postpone, not resume, or not play the game.
• A protest may be filed for a violation of the applicable eligibility rules.
• To be admissible, the captain must notify the crew chief within 15 minutes after the game ends and sign the scoresheet in the protest column.
• The team must submit protest reasons in writing within 1 hour after the game ends and pay a CHF 1,500 fee if the protest is rejected.
• The competent body decides immediately and no later than 24 hours after the game ends, and may order partial or full replay using reliable evidence.

💡 Memory Hook

Eligibility protests are “admissible fast”: CAP within 15 min, written reasons within 1 hour, decision within 24 hours.

📖 10. Forfeit and game lost by default

🔑 Key Concepts & Definitions

• Forfeit : A forfeit is a result awarded when a team fails to meet required conditions to play, so the opponent is declared the winner.
• Game lost by default : A game lost by default is a result given when a team is unable or unwilling to compete, leading to an automatic loss.
• Default result : A default result is the official outcome assigned without normal play because one team cannot proceed under the rules.

📝 Essential Points

• A forfeit ends the game outcome without the normal completion of play, with the opposing team awarded the win.
• A game lost by default is treated as an automatic loss for the non-complying team.
• Default outcomes are recorded as official results even though the game may not be played to completion.
• If a team cannot start or continue as required, the rules provide for a default/forfeit outcome rather than continuing play.

💡 Memory Hook

Default = “no show” → automatic loss; Forfeit = “can’t meet conditions” → opponent wins.

📖 11. Violations definition and ball awarded

🔑 Key Concepts & Definitions

• Violation : A violation is a rules breach that stops play and results in the opposing team being awarded the ball.
• Out-of-bounds ball : An out-of-bounds ball is a ball that has crossed the boundary lines and play must restart with a throw-in.
• Throw-in violation : A throw-in violation is an error during a throw-in that causes the throw-in to be unsuccessful and play to restart for the other team.
• Penalty situation : A penalty situation is the set of circumstances that determines what penalty is applied after a foul or violation.

📝 Essential Points

• A violation leads to a stoppage of play and the ball is awarded to the opposing team.
• Out-of-bounds play restarts with a throw-in rather than a live-ball continuation.
• A throw-in violation results in the throw-in being awarded to the other team.
• The penalty situation governs what restart/penalty applies after the infraction.
• Violations are distinct from fouls because violations do not count as personal or technical fouls.

💡 Memory Hook

Violation = “V” for “Vested in the other team”: play stops and the ball goes to opponents.

📖 12. Scorer and assistant scorer duties

🔑 Key Concepts & Definitions

• Scorer duties : Scorer duties : The scorer records the official score and game statistics using the scoresheet and table procedures.
• Assistant scorer duties : Assistant scorer duties : The assistant scorer supports the scorer by tracking required information and helping maintain accurate records.
• Scorer’s table : Scorer’s table : The table area where the scorer and other table officials operate during the game.
• Scoresheet examination : Scoresheet examination : The process of checking the scoresheet for correctness and completeness as part of the officials’ procedures.

📝 Essential Points

• The scorer’s table is the location where scoring and related record-keeping are handled during the game.
• The scorer records scoring events and statistics on the scoresheet using the prescribed procedure.
• The assistant scorer supports the scorer’s record-keeping to keep the scoresheet accurate.
• Scoresheet examination follows a defined procedure to verify the recorded information.
• Scoring decisions at the table must be reflected on the scoresheet in the correct form and order.

💡 Memory Hook

Scorer = Score + Stats; Assistant = Second set of eyes at the scorer’s table.

📊 Synthesis Tables

Court vs floor and backcourt vs frontcourt

Item	What it includes	Key boundary
Court	Flat, hard playing surface	Measured 28 m × 15 m from inner edge of boundary line
Floor	Court plus boundary lane	Minimum 2 m lane around court; minimum 32 m × 19 m
Backcourt	Own basket + inbounds part of backboard + court part	Limited by endline behind own basket, sidelines, and centre line
Frontcourt	Opponents’ basket + inbounds part of backboard + court part	Limited by endline behind opponents’ basket, sidelines, and inner edge of centre line nearest opponents’ basket

⚠️ Common Pitfalls & Confusions

1. Mixing up court vs floor measurements: the 28×15 court is measured from the inner edge of the boundary line, while the floor adds a minimum 2 m boundary lane to reach at least 32×19.
2. Thinking the boundary lines are part of the court: the endlines and sidelines limit the court and are not part of the court area.
3. Confusing player location when airborne: location status is retained from the last floor contact point, including whether you are considered on/over centre line, 3-point line, free-throw line, restricted area lines, or a
4. Misapplying out-of-bounds: the ball is out-of-bounds if it touches the floor or any object above/on/outside the boundary line, or backboard supports/back of backboard, and the last player to touch/be touched causes it.
5. Forgetting the 3-second rule conditions: it applies only while the team is in control in the frontcourt and the game clock is running, and it is the opponents’ restricted area.
6. Overlooking no-charge semi-circle protection requirements: the defensive player must have one or both feet in the no-charge semi-circle area for the protection to apply.
7. Assuming shot clock resets like the game clock: after certain stoppages it resets to 24 or 14 seconds depending on where the throw-in is and how many seconds were displayed when stopped.

✅ Exam Checklist

1. State the official court dimensions (28 m × 15 m) and explain how they are measured from the inner edge of the boundary line.
2. State the minimum floor dimensions (32 m × 19 m) and the minimum boundary lane width (2 m) and what the lane is for.
3. Define backcourt and frontcourt precisely using the basket/backboard and the exact court boundaries (centre line vs inner edge of centre line).
4. List what determines a player’s and a referee’s location, and state the airborne rule (retain the status from the last floor contact point).
5. Define boundary line and out-of-bounds player/ball, including the rule that the last player to touch/be touched causes the ball to go out-of-bounds.
6. Explain the jump ball situation and the penalty for jump-ball-related violations (throw-in nearest infraction except directly behind the backboard).
7. Apply the 3-second rule: identify the opponents’ restricted area, the ‘frontcourt control + game clock running’ condition, and the ‘both feet outside’ requirement to be established outside.
8. Explain the no-charge semi-circle rule conditions for when contact by an airborne offensive player is not called as a team control foul (including the defender’s foot contact requirement).
9. Describe throw-in restart locations for key foul types (unsportsmanlike/disqualifying: frontcourt throw-in opposite scorer’s table) and the centre line throw-in at the start of quarters other than the first.
10. Explain correctable errors category 1 procedures for: wrong free-throw player, wrong free-throw direction, and erroneous awarding/cancelling of points, including the ‘nearest stop’ restart concept.
11. Explain protest admissibility timing: captain notification within 15 minutes, written reasons within 1 hour, CHF 1,500 fee if rejected, and competent body decision within 24 hours.
12. Differentiate game lost by forfeit vs game lost by default using the exact conditions and the resulting score/classification outcomes.
