PRESENTATION TOPICS Part 1 – OfficiatingPrinciples Part 2 – Terminology Part 3 – Signals Part 4 – GameProcedures for a Crewof Two Officials Part 5 – GameProcedures for a Crewof Three Officials

TERMINOLOGY Ball Side: The location of the ball in the normal frontcourtoffensive alignment of a team. In dividing the court downthe middle, (using the basket as a center point), end line toend line. The side of the court where the ball is located isball side. Bump and Run: A technique when one official “bumps”another official out of his/her current position and thevacating official “runs” down into a new position. Center Official: The outside official who is in the off‐ballposition, midway between a step below the free‐throw lineextended and the top of the circle. The Center official maybe table side or opposite side.www.nfhs.org

TERMINOLOGY Close Down: Movement of an official (a step or two)related to movement of the ball. The Trail and Centerclose down toward the end line; the Lead closes downtoward the nearest lane line extended. Lead Official: The official positioned along and off theend line. The Lead official may be table side oropposite the table, but will be on the same side of thecourt as the Trail. Move to Improve: A technique that means to “moveyour feet” in order to “improve your angle” on theplay. Helps to eliminate being “straight‐lined.”www.nfhs.org

TERMINOLOGY Opposite Side: The side of court opposite the tableside. Primary Coverage Area (PCA): Area of responsibilityfor each official. PCA is determined by ball location. Rotation: A live‐ball situation, whereby the location ofthe ball keys a change in coverage for the officials. Thisis implemented when the Lead official moves to ballside dictating a change of position by the Center andTrail officials. The Lead should not rotate until all threeofficials are in the frontcourt.www.nfhs.org

TERMINOLOGY Straight‐Line: Refers to a situation that occurs whenan official allows his/her vision to be obstructed by aplayer or players; having to look through a playerinstead of in between players. When a straight‐lineoccurs, the official is not able to accurately see playingaction. The situation is also known as getting“stacked.” Strong Side: Side of the court determined by thelocation of Lead official.www.nfhs.org

TERMINOLOGY Switch: A dead‐ball situation created by an official whocalls a violation or foul. After a violation is called or a foulis reported to the table, there may be a change in positionof the officials. The switch will normally involve the callingofficial moving to a new position on the court. Table Side: The side of the court where the scorer’s andtimer’s table is located. Trail Official: The outside official positioned nearest thedivision line, approximately 28 feet from the end line(near the top of the three‐point arc). The Trail official maybe table side or opposite side, but will be on the same sideof the court as the Lead. 11

TERMINOLOGY Weak Side: The side of the court opposite theLead official; the Center’s side of the court. Wide Triangle: All three officials forming thegeometric shape of a wide triangle; keeping allplayers and activity within the triangle. 12

SHOT & REBOUND COVERAGE 22

THREE‐POINT SHOT COVERAGEIf both C and T indicatethe 3‐pt attempt, Treferees defense onshooter and stays withshot; C releases andcovers reboundingC/T should mirror theother official’s “good”signal 23

ROTATIONS Rotations should be thoroughly discussedat the pregame conference Ball location keys the need for a rotation The T or C can facilitate a rotation, butONLY the L initiates a rotation A rotation should only take place when allthree officials are in the frontcourt A rotation begins when L moves laterallyand penetrates the key area 24

ROTATIONS Rotation is not complete until L passesbeyond far lane‐line extended L must officiate play in the post – evenwhile moving across the lane If the L begins to rotate and ball is quicklyreversed or a quick shot taken – L does nothave to complete rotation There should rarely be two T’s – there maybe two C’s for brief periods of time 25

ROTATIONS If a trap occurs near the division line on C’sside of court, C moves higher to officiatethat play and L should initiate a rotation If L does not rotate – C should go back to anormal C position when play permits Remember, only the L initiates a rotation!The C only facilitates the rotation in thiscase. 26

ROTATION SEQUENCEL goes to ball‐side, T closes down, C completes rotation(last to rotate)

TRANSITION AFTER ROTATION All officials must recognize rotation hasoccurred If L rotated late and a transition occurs –it is old L’s (new T’s) responsibility to lookup court making sure partners picked uprotation If not, the new T should be prepared toadjust his/her location on the floor 28
