Research on college swimming, written for families.

I run the database behind this site, and these are the questions I could not get a straight answer to when I started looking. Every number traces back to a query I can show you. Where the data stops, the article says so instead of guessing.

What happens to the swimmers who are slow at twelve?

A month ago I sat with my daughter's medical results and a question I could not answer with feeling alone. This is the closest thing to an answer I have found, and it is the reason this site exists.

D1 swimming for international families: how fast, and who actually pays

The Division I schools that enroll the most international students are also the fastest and the most expensive. The ones that will genuinely fund an international swimmer are cheaper and far easier to get into. And if your swimmer is a boy, the list of schools that fit both is shorter than anyone tells you.

What were future D1 swimmers doing at 12, 14, and 16?

Parents want to know if their child is 'on track.' So I followed the times of swimmers who did reach a D1 roster, back to when they were twelve. The most useful thing in the data is not a target. It is where the improvement actually happens, and where it does not.

Roster dynamics

If you have a son, the men's programs are mostly at D3, not D1

Men's college swimming has been quietly cut for years, and the cuts landed hardest at the top. A family with a son is running a smaller search than a family with a daughter, and the biggest part of it is not where most people look first.

Recruiting standards

How fast do you actually need to be for D1, D2, D3, or NAIA?

Every recruiting site hands you one cutoff time per division. That single number hides the thing families most need to see: the real gap in college swimming is not between the divisions parents agonize over. It is between D1 and everyone else.

How these are written

Written by a swim parent who builds the data.

ITIvan TsaiFounder and editor

I have spent more than fifteen years building large-scale data systems for major technology companies in Asia, I run a competitive swim club, and I am the father of three daughters. One is a competitive swimmer; another has competed at the highest international level in artistic swimming, including world junior and World Cup titles.

  • Every number is checked against its source before publication. Draft figures are matched cell by cell against the query that produced them. A number that cannot be traced does not run.
  • Times describe swimmers who made it, not thresholds anyone must clear. These athletes all reached a college roster, so the numbers show the range they came through — never odds or cutoffs.
  • Undisclosed is written as undisclosed. When a school does not publish a policy, the article says so rather than estimating.
  • Corrections are logged on the article, not quietly overwritten.
