TALKING POINTS

GLOSSARY & DEFINITIONS

Getting started at EBBOA

EBBOA — East Bay Basketball Officials Association; your local association.

CIF / NFHS — CIF governs California high‑school sports; NFHS writes the high‑school rules.
Assignor — the person who assigns you to games (at EBBOA via ArbiterSports).
Arbiter / Arbiter Pay — the platform for schedules/availability, and how you get paid.
Availability — the dates you tell the assignor you can work; keep it current.
Crew / Partner — the officials working a game together; your partner(s) on the floor.
Mentor — a veteran assigned to develop you; use them.
The Signal / Teams — EBBOA's newsletter and its Microsoft Teams hub for training and dialogue.
Pregame conference — the crew's meeting before tip to align on coverage and communication.

The Floor

Division line — midcourt line separating frontcourt and backcourt.
Frontcourt / Backcourt — the offensive half vs. the defensive half for the team with the ball.
Lane / Key / Paint — the free‑throw lane area.
Baseline (endline) / Sideline — the boundary lines.
Coaching box / Bench area — where the head coach and team may be.
Table — the scorer and timer; where you report fouls.

Positions & mechanics (2‑ and 3‑person)

Referee (R) / Umpire(s) — the R is the crew chief; umpires are the partners.
Lead / Trail / Center — the three spots in a 3‑person crew (Center only exists in 3‑person).
Primary / secondary coverage — your area of first responsibility vs. help.
On‑ball / off‑ball — officiating the ball vs. the players away from it.
Strong side / weak side — the side of the floor the ball is on vs. away.
Rotation — the coordinated switch of positions, triggered when the Lead crosses the lane.
Straight‑lined — losing your angle so players are stacked between you and the play (bad — move).

Clock & Possession

Live ball / dead ball — whether the clock/play is active; lots of rules hinge on this.
Throw‑in — putting the ball in play from out of bounds; often at a designated spot.
Held ball / jump ball — tied‑up ball; resolved by the AP arrow (not a toss).
Alternating‑possession (AP) arrow — decides who gets the ball on held balls and to start quarters.
Timeout / intermission — stoppage requested by team; break between quarters/halves.

Fouls & violations (the core split)

Foul vs. violation — a foul is illegal contact/behavior (may bring free throws); a violation is a rule break that just gives the ball to the other team.
Personal / common / shooting foul — contact fouls; shooting fouls bring free throws.
Player‑control / team‑control foul — offensive fouls; no free throws.
Bonus — free throws once a team hits the foul limit for the QUARTER
Technical / intentional / flagrant — non‑contact or severe fouls with escalating penalties; flagrant = ejection.
Block / charge — the block‑or‑charge decision, judged by the defender's position.
Hand‑checking — illegal use of hands to impede the ball handler (a point of emphasis).
Traveling / double dribble / carry — the common ball‑handling violations.
3‑seconds / closely guarded (5) / 10‑seconds — the lane, holding‑or‑dribbling, and backcourt counts.
Backcourt violation / out of bounds / kicked ball — location and possession violations.
Goaltending / basket interference — illegal touching of a shot near the rim.

Judgment & game management

Advantage / disadvantage — the heart of officiating: only penalize contact that actually affects the play.
Incidental / marginal contact — legal contact that doesn't create an advantage.
Legal guarding position (LGP) — a defender who got there first, facing the opponent, feet down.
Verticality — a defender's right to the space straight above them.
Point of emphasis (POE) — a rule NFHS asks officials to call more consistently this year.
Bench decorum — managing coach/bench behavior (a current POE).
Correctable error / resumption‑of‑play — fixable mistakes within a window, and the anti‑delay procedure.

Signals & communication

Stop‑the‑clock / preliminary signal — raise the fist to stop play, then show what you have.
Reporting — going to the table to clearly report a foul (number, color, foul type).
Beckon / handshake — waving substitutes in; the crew's "we've got each other" mindset.

A tip for teaching it: rookies remember these faster when the term is tied to a moment — walk each one at a slow scrimmage rather than reading definitions. That's exactly the Whistle‑to‑Wisdom, "study it, then apply it" loop.
