How to read a match rate, mine too

Here’s something that sounds contradictory and isn’t. A medical school can accurately report a high USMLE pass rate and a high residency match rate in a year when a large share of the students who started never finished.

Both numbers can be completely true at once. The explanation is arithmetic, and specifically it’s the denominator.

This is a skill worth learning early, because you’ll be reading statistics about your future for the next several years, and almost nobody teaches you how.

What a denominator does to a percentage

Every percentage is a fraction, and the bottom half decides what the top half means.

“Ninety-seven percent match rate” tells you very little on its own. Ninety-seven percent of whom? Everyone who matriculated in that cohort? Or the students who made it far enough to sit their exams, finish clinicals, and certify a rank order list?

Those are wildly different claims. The second is counted only over the people who got that far, which means anyone who left along the way has come out of the bottom of the fraction. Attrition doesn’t drag that kind of match rate down. It pushes it up.

The same logic applies to a USMLE pass rate. Denominate it on first-time test takers and you’ve excluded everyone who left before reaching the exam.

None of this requires anyone to be acting in bad faith. Schools report the figures that are standard to report, and survivor-denominated rates are standard almost everywhere in education. The arithmetic works the way it works regardless of intent, which is exactly why you need to be able to see it.

The check that takes a minute

Find the percentage. Then look for the sentence that says what it’s counted over. A school reporting in full writes something like “of the N students who matriculated in this year, N graduated.”

If a percentage appears without a denominator, treat it as not disclosed. Not as bad news. Not as good news either. As missing information, which is a genuinely different thing from either, and it’s how you should read any statistic on any school’s website.

One more pattern worth knowing. If a school’s Step 2 CK pass rate is noticeably higher than its Step 1 rate, it’s fair to ask why. There are several ordinary explanations, and one of them is simply that the two exams have different denominators, because students who struggled at Step 1 may not be in the Step 2 CK group.

Now apply it to me

You should run this on my numbers too, and I’d rather tell you how than have you find out later.

When I say I’ve coached more than 500 students, that’s a count, not a rate. It tells you something real about volume and nothing at all about outcomes. Those are separate claims and they deserve separate scrutiny.

If I ever quote you a percentage, about anything, ask me the same question you’d ask a school. What is it counted over, and where did it come from. Every figure I put in front of you carries a source link and a date showing when it was last checked. That’s deliberate, because a number you can’t trace is a number you shouldn’t lean on.

Asking for the number directly

Most Caribbean schools don’t publish a four-year attrition rate. It isn’t a standard disclosure and many institutions have simply never been asked for it. You’re still entitled to ask.

Email admissions and ask for the four-year attrition rate by entering cohort. Ask specifically by cohort, because an aggregate across many years smooths out the recent trend, which is the part you actually care about.

Keep whatever comes back. It’s the only version of this information that’s specific to the year you’d be starting, and it’s far more useful to you than a figure from a prospectus printed three years ago.

Two things you can verify yourself

Both come from primary sources rather than a prospectus, and neither takes long.

Accreditation status, from the accreditor rather than from the school’s own page about its accreditation. Regional accreditors publish their own lists, including current status and review dates, and a status can carry conditions or be under review.

Whether the school’s accrediting authority has been through a comparability review. The US Department of Education publishes those determinations. This is one of the inputs that governs what options are open to you later, which is why it’s worth checking before you enroll rather than in your final year.

I don’t rank schools here and I won’t do it in public. What I’ll say is that the questions above are answerable, they’re specific, and they give you something more solid to decide on than a campus visit.

Why attrition is the number that matters most

Attrition is the outcome that makes every other consideration moot, because a student who doesn’t finish never sits Step 2 CK, never enters the Match, and never becomes a physician, while still carrying whatever they borrowed.

That’s why it belongs at the front of your due diligence. It’s usually at the back, and not because anyone is being careless. Attrition is an uncomfortable thing to ask about when you’re excited, and the information is genuinely harder to find than the numbers a school leads with.
