2024-25 Swimming

Manuals provide the most up to date policies, rules, and regulations for Iowa High School Athletic Association sports in the regular season and postseason. Member school athletic directors and head coaches seeking more information or clarifications on the contents of this manual should contact the IHSAA sport administrator for this sport: Jared Chizek. All other inquiries should be directed through athletic directors or coaches at member schools or host schools. 

All the rules and regulations governing this sport can be found in the annual NFHS Rule Book, which all member schools receive from the IHSAA, excepting updates or experiments approved by the Board of Control.

Each member swimming school receives one copy of the National Federation of State High School Associations Swimming, Diving & Water Polo Rules Book. Unless other rules are adopted by the Board of Control, member schools will follow the rules published in the National Federation’s Rules Book. Schools are asked to keep their 2024-25 rules book through the 2025-26 swim season.

2024-25 Rule Updates

NFHS Rule Changes

4-1-4Removes the word “clerical” from the description of the official’s authority over a meet through the completion of any reports that are responsive to actions occurring while the referee has jurisdiction.  

Removes language that permits an announcement of a disqualification on the basis of a Rule 3-2-2 violation to be made by the public address announcer if the coach cannot be located.    

NFHS Rule Adoptions & Exceptions

The following rule adoptions and exceptions, as noted in the NFHS Swimming Rules Book, have been adopted by the Iowa High School Athletic Association: Rule 3-1-2(d) Unlimited team entries for invitational and non-varsity meets; Rule 1-2-3 Exhibition competitors allowed, as per rule; Rule 5-1-1 Note 3 unlimited individual entries in pentathlon-type meets; Rule 5-1-1 Note 1 Swimming events may be modified for non-championship multi-team competition; Rule 7-2-4 Suspended meets may be resumed from the point of the suspension.


Rule 3-2-3(note) Entry of relay teams without individual names has not been adopted. Relay teams are to be entered with individual names, including alternates, on the entry form. The relay shall count as an event only for the four swimmers who actually compete.

Schedule Information

Schools may not start swimming practice before Week 19/November 11, 2024, and no practice may be conducted after the state meet is concluded.

No interscholastic swimming contest may be held by member schools of the IHSAA prior to Week 21/November 25, 2024.

Each school is allowed a maximum of 12 competition meets prior to district competition. The 12 meet limitation pertains to individual swimmers as well as a school’s team.

Example: You may have 12 freshmen meets, 12 junior varsity meets, and 12 varsity meets. Each individual swimmer may compete in a maximum of 12 meets during the regular season, not including district and state competition.

If a school is competing in a multiple level meet (Example: junior varsity/varsity, sophomore/varsity, freshmen/junior varsity), or a double dual, on the same day, at the same site, an individual may compete in both meets as long as he does not violate the NFHS individual participation rule (3-2-1). That rule states, “A competitor shall be permitted to enter a maximum of four events, no more than two of which may be individual events.”

One scrimmage between schools is allowed in swimming.

Member schools are not permitted to participate in any interscholastic swimming competition from December 24 through January 1. This does not exclude a school from practicing or scrimmaging during this time.

During all regular season competition (dual, double dual, triple dual, triangular, and tournaments), a mandatory 10 minute break will be taken immediately following Event #4, the 50 yard freestyle, and Event #8, the 200 yard freestyle relay.

Contest Information

Proper Supervision and Swimming Practices & Meets

Administrators and coaches need to be aware of the following section of the Iowa Code. Rule (641-15.4(4)”d”(4) of the Iowa Administrative Code states, “For a structured swimming program, such as lap swim, competitive swimming, water exercise classes, swim lessons, and physical education classes, a lifeguard is not required provided the program is supervised by an instructor, teacher, or coach who is a lifeguard or has current certification from the American Red Cross in basic water rescue, first aid, and infant, child and adult CPR; or equivalent training approved by the Department of Health. An instructor, teacher, or coach may be responsible for a maximum of 30 persons within a structured activity. If more than 30 persons are involved in a structured activity, a second qualified supervisor must be present.”

Warmup Guidelines

Each swimming school should have warm-up guidelines established to help prevent injuries. The Swimming Advisory Committee recommended many years ago the following guidelines for meet warm-ups. Suggested meet warm-up procedures also appear in the NFHS Swimming & Diving Rules Book.

A supervisor should be on deck during the entire warm-up period. (Any personnel supervising warm-ups should meet the Iowa Administrative Code requirements of being certified in emergency water safety or being a lifeguard)

Swimmers should enter the water feet-first, except for starts which are limited to specific lanes.

Specify Lanes 2 and 5 (six-lane pool) or Lanes 2 and 7 (eight-lane pool) as one-way sprint lanes with racing starts permitted at the starting end of the pool.

Place a cone or similar sign on the starting platforms of the lanes not specified as one-way sprint lanes.

Specify center lanes for circle swimming (two lengths of the pool beginning at the starting end).

Specify the outside lanes as pace lanes (swimmers swim one or two lengths from an in-water push off position from the starting end of the pool).

May specify lanes for relay starts during the last 15 minutes of warm-up.

Coaches should stand at the starting end of the pool and verbally start swimmers for starts and pace work.

Swimmers should not be allowed on a starting platform when a backstroker is executing a start in the same sprint lane.


Regulations Pertaining to Scrimmages

A member school may have a maximum of one interscholastic scrimmage against other high schools after the first legal practice date provided:

The scrimmage is a bona fide scrimmage where no public announcement has been made, no admission charged, and no score is kept or recorded.

No school time may be used for traveling and participating in a scrimmage season.

Up to four schools may be involved in a scrimmage. There can be four schools at a site and each school will be charged with only one scrimmage date.

Scrimmages must take place at one of the school’s regular practice facilities.


State Qualifying Tie-Breaking Procedure

The fastest thirty-two (32) individual swimmers and twenty-four (24) relay teams from district competition will qualify for state competition. In the event of a tie for the 32nd individual event position or the 24th relay position, the following tie- break procedure will be used:

1st criteria – grade (senior swimmers have precedence over juniors, etc. (Example: Joe Jones, senior would qualify rather than John Smith, junior as John Smith has another opportunity to qualify). The relay team with the most seniors will have precedence over the team(s) with fewer total upperclassmen, etc. If each relay team has the same number of seniors, the team with the most juniors would have precedence, followed by the most sophomores.) [Example 1: Relay Team A with 1 senior, 2 juniors, and 1 sophomore would qualify before Relay Team B with 4 juniors. Example 2: Relay Team A with 2 seniors, 1 junior, and 1 sophomore would qualify before Relay Team B with 1 senior and 3 juniors.]

2nd criteria– if a tie still exists – the individual or relay team with the fastest district meet seed time would be the qualifier. 3rd criteria – if a tie still exists an alphabetical system will be used to break the tie.  In 2025, the individual or relay team from the school listed first in the IHSAA Directory will advance to the state meet. In 2026, the individual or relay team from the school listed last in the IHSAA Directory will advance to the state meet. If a tie exists between competitors from the same school, the last name of the competitor as it appears on the official district meet roster will be used to determine the qualifier using the same even and odd numbered year system. In 2025, the individual whose last name comes alphabetically first relative to his tied teammate will advance to the state meet. For 2026, the individual whose last name comes alphabetically last relative to his tied teammate will advance to the state meet.If a tie still exists, the competitors’ first names will be used. Any ties among qualifiers will be broken using the same procedure to determine heat and lane assignments.


State Meet Venue

Schools and individuals may practice at the state meet facility, Campus Recreation and Wellness Center, at any point in the season, when the facility’s management allows.


Recommended Water Depth

The Board of Control of the Iowa High School Athletic Association’s policy regarding water depth in the starting end of swimming pools is as follows: “In pools with water depth of 5′ or more, the staffing platform may be used in accordance with Rule 2, Section 7, Article 2 of the Swimming, Diving, and Water Polo Rules Book published by the National Federation of State High School Associations. If the depth of the water is les than 4′, the start for all swimming events shall begin in the water.


Swimming Meet Checklist

For many years, the Iowa High School Athletic Association, through the Swimming Coaches Advisory Committee, provided a swimming meet checklist to be used when planning major swim meets. The National Federation now prints a similar checklist in the Swimming and Diving Rule Book. Please refer to the NFHS Web site for suggestions and guidelines for planning major swim meets.


Mandatory Reporting of Stats

Based on a recommendation from the Swim Coaches Advisory Committee, head varsity swim coaches are required to enter meet results on Meet results need to be entered by 3:00 PM on Tuesday, December 10, Tuesday, January 14, and Tuesday, February 4.
