Swim Meet Terminology: A Parent's Plain-English Glossary

Updated July 2026 · about a 5 minute read

Your kid's first swim meet, and suddenly everyone is talking about heats, seeds, and cuts like it is a second language. It kind of is. Here is a plain-English glossary of the swim meet terms parents actually run into, grouped by when you will hear them.

How a meet is organized

Meet
The whole event, often a full day or a weekend, made up of many individual races.
Session
A block of the meet, like "Saturday morning." Large meets split into several sessions.
Event
A single race type, usually numbered, for example "Event 12: Girls 10 and Under 100 Freestyle."
Heat
When more swimmers enter an event than there are lanes, it is split into heats that race back to back. Your swimmer is in one of them.
Lane
The numbered lane a swimmer races in for their heat.
Seed time
The time a swimmer entered with, usually their recent best. It decides which heat and lane they are placed in.
Heat sheet (meet program)
The full list of every event, heat, lane, and swimmer. This is the document Heat Guardian reads for you.
Psych sheet
A pre-meet list of entries ranked by seed time, before heats and lanes are assigned.
Warm-up
Pool time before racing starts for swimmers to loosen up.
Clerk of course (bullpen)
A staging area where younger swimmers are gathered and lined up before their race.

The race itself

Blocks
The starting platforms at the end of the pool.
Deck
The pool-deck area around the water where swimmers, coaches, and officials are.
Start / false start
The dive-in at the buzzer. Leaving early is a false start.
Strokes
Freestyle (free), Backstroke (back), Breaststroke (breast), and Butterfly (fly).
IM (Individual Medley)
One swimmer swims all four strokes in order: fly, back, breast, free.
Relay
Four swimmers each swim a portion, called a leg, of one race.
Split
The time for one part of a race, like each 50 of a 100. Useful for pacing.
Touch pad
The electronic pad on the wall that records a swimmer's official time when they touch.

Times and standards

Course
The pool length. SCY is short course yards (25 yd), SCM is short course meters (25 m), LCM is long course meters (50 m). Times differ by course.
Time standard / cut
A qualifying time for a bigger meet. Swimming at or under it means you "made the cut."
Motivational times
A ladder of standards (B, BB, A, AA, AAA, AAAA) showing a swimmer's level for their age and event.
PR / PB
Personal record or personal best: a swimmer's fastest-ever time in an event.
Drop
How much time a swimmer took off their previous best. "She dropped two seconds."
NT (no time)
Shown when a swimmer has no prior time in an event. They are usually seeded in an early heat.
Taper
The lighter training before a big meet so swimmers are rested and fast.

Results and officials

Prelims and finals
In prelims-finals meets, everyone swims in the morning (prelims); the top finishers return at night (finals).
Scratch
Withdrawing from an event you were entered in.
DQ (disqualification)
A swim ruled illegal, such as an illegal turn or stroke. It does not count for a time or place.
Exhibition
A swim that counts for a time but not for place or team points.
Place / points
Where a swimmer finished and any team points earned.

Frequently asked questions

What is the difference between a heat and an event?
An event is the race itself (for example, the 100 Freestyle for a given age and gender). A heat is one group of swimmers racing that event at the same time. A busy event is split into many heats that swim back to back.
What is a seed time?
The best recent time a swimmer entered the meet with. Meets use seed times to group swimmers of similar speed into the same heats and lanes.
What does making a "cut" mean?
A cut is a qualifying time standard for a bigger meet, like a championship. If a swimmer races at or under that time, they have made the cut and qualified.
