Why poolside registers matter

A register tells the club who is in the water. That matters most in an emergency, when the coach needs to know exactly who to account for, and it matters every week for a quieter reason: attendance drifting is often the first sign that a swimmer is about to leave. Registers get skipped when they are slow. Make taking one quicker than not taking one, and coaches keep them.

What a register does for the club

Safety comes first. If the building is evacuated, the coach needs to know who was in the session. A register taken at the start, not reconstructed later, is the list.

It supports the duty of care. With the register on a phone, a swimmer's medical notes and emergency contacts are a tap away if something happens poolside.

It gives early warning. A swimmer who goes from four sessions a week to two, then one, is telling the club something. Spot it early and a coach can have a conversation while it still makes a difference.

It is evidence. Attendance supports squad decisions, selection conversations, fee queries and coach hours. When a parent asks how often their child has trained, the club can answer.

Why registers stop being taken

• Paper registers get wet, lost, or left in a coach's bag.
• Taking it means opening a separate app that does not know who is in which squad.
• The coach has three lanes to start and no hands free.
• Absences arrive in a group chat and have to be cross-checked.
• Nobody ever looks at the data, so it feels pointless.

What makes a register quick enough to keep

1. It knows the squad. The session's swimmers are already listed.
2. It works on a phone at the poolside, in seconds, including where the signal is poor.
3. Present, absent or late takes one tap, with a reason where needed.
4. Absences arrive before the session. When a parent marks a child absent, it is already on the register.
5. Someone uses the data. Coaches and the committee can see patterns over weeks.

A note on absence reasons

An absence reason can reveal a health condition. Clubs should ask coaches to record that a swimmer was absent, or ill, without adding health detail, and keep medical information in the place designed for it, where only roles with a duty of care can see it.

How Olympus Swim helps

In Olympus Swim the coach takes the register on a phone at the poolside, from the session's own swimmer list: present, absent or late, with a reason. Opening a register needs a connection once; taps then work offline. Medical notes and emergency contacts are available from the register view. Absences marked by parents in the parent portal appear on the coach's register before the session. Attendance history builds over the season, and can be exported.

Common questions

Do swimming clubs have to take registers? Registers are part of a club's duty of care and are how a coach accounts for everyone in an emergency. Check your governing body's guidance and your club's own policies.

How long should taking a register take? Under a minute, ideally. If it takes longer, coaches will skip it when they are busy.

Should we record why a swimmer was absent? A short reason is useful. Avoid recording health detail in an absence note; keep medical information where access is restricted.
