The comment about sports recruiting and early decision is right on. Most, but not all, Div 3 schools really go out of the way for targeted, recruited athletes. But Grinnell has placed special emphasis on this as shown in these recent articles, and the second one has some particularly interesting stats:

You’ll note that nearly half of campus visitors (42-48%) are students interested in sports, but only 14% are recruited athletes. Colleges usually discuss only “athletes” and don’t give data on how many of those are recruited. But it’s only the recruited ones who are hosted by the teams and whose applications are “tagged” or “sponsored” (I’ve heard both terms used) by the athletic department. I have seen data that says at most schools such applications are accepted at a rate of around 95% because the student has to be pre-qualified in advance by the coach working with the admissions office.
Our D experienced visits both as a recruit and as a non-recruit at a school where she might have been a walk-on but not a starter on the team. At the non-recruit school the coach was willing to meet with her, but was very unresponsive to texts and only offered a time after she’d been on campus for a while (she turned it down - the whole experience was sour for her, not just the team experience). At recruited schools she stayed with a team member and often was accompanied by different team members throughout. At one school (not Grinnell) she and her mom were taken out to dinner at a nice local restaurant by the coach. In all cases the details of the visit were well coordinated and well communicated in advance and there was special effort made to make her welcome and answer all her concerns.
