Are these times for all children or just competitive swimmers?

Competitive swimmers only. Every time comes from a swimmer racing at a sanctioned Australian competition, so the median is the middle of the competitive field — already well ahead of the average child of the same age. An 8-year-old anywhere near these medians is doing well.

My 8-year-old is slower than the median. Should I worry?

No. Half of all competitive swimmers are below the median by definition, entry age varies by years, and year-on-year improvement matters far more than any single benchmark. A swimmer who starts behind and improves steadily routinely passes swimmers who were faster at 8. Trajectory beats snapshot.

How to read this

Median means half of competitive swimmers that age are faster and half are slower. Top 25% and top 10% mark the sharper end of the field. These are long course (50m pool) times. At this age a short course (25m pool) PB can be faster or slower than long course, so compare like with like. To check whether your swimmer is close to a championship standard, try the qualifying times calculator.

A single time is a snapshot. What matters more is how much a swimmer improves each year — see how much swimmers improve by age.
