The rankings on this site are only worth something if you know exactly what they are — and who made them.

Who built this — and yes, he’s on the list

TutorRank was built and is operated by Volak S., a working math tutor. He also appears in these rankings, currently at or near the top of several of them. He chose the scoring rules — the weights, the floors, the formula — and those rules affect where he places. You should factor that in when you read the table, and we’d rather tell you than have you find out.

Every one of those rules is published in full on the methodology page. Reasonable people would choose different numbers and get a different order. What we can promise is that the rules are stated openly and applied identically to everyone — including the person who wrote them.

The testimonials are real, and you can check every one

Nothing here is written, paraphrased, or invented by us. Every scored data point comes from a testimonial published on a tutor’s own public Wyzant or Preply profile, by an actual student or parent. A testimonial only counts when it states a concrete before → after result — “went from a 72 to a 92,” “a C to an A.”

Each tutor’s page reproduces every testimonial verbatim, next to the grade change we read out of it and whether it scored or was excluded. So you never have to take our word for a ranking — click the tutor, read the actual reviews, and audit the arithmetic yourself.

Where these rankings are a bad guide

The score measures one narrow thing: documented grade improvements that students happened to write down with numbers. That makes it a weak or useless signal in several common cases.

Use this as one input: a way to surface tutors whose results were concrete enough that a student bothered to write the number down. It is not a measure of teaching quality, and it is not a substitute for talking to the tutor.

The rankings are nearly all Wyzant — and that’s our fault, not Preply’s

Of the tutors ranked here, all but one are from Wyzant. There are two mundane reasons, and neither of them is that Preply tutors are worse.

1. We collected far more Wyzant data. We’ve read 281 Wyzant tutors against just 39 from Preply — Preply’s public listing caps out quickly. A 7:1 sampling imbalance produces a 7:1 result, and that is a limitation of our collection, not a finding about tutors.

2. Our $60/hr floor excludes most of Preply. Preply’s marketplace simply prices lower: 67% of the Wyzant tutors we read charge $60 or more, but only 10% of Preply’s do. So a rule we chose for unrelated reasons quietly filtered out an entire platform.

We want to be exact about one thing, because it would be easy to draw the wrong conclusion: Preply reviewers are no vaguer than Wyzant’s. Having now read every testimonial we hold from both platforms, the share that cites a concrete before → after grade is 0.82% on Wyzant and 0.73% on Preply — the same, to within noise. Students on both platforms overwhelmingly write “she’s wonderful” rather than “I went from a 72 to a 92,” at almost exactly the same rate.

So there is no finding here about Wyzant tutors being better, and the composition of this board is not evidence of one. It reflects where we happened to point our scraper, and a price rule that turned out to exclude one marketplace far more than the other. Both are our limitations to fix, and we’d rather name them than let the leaderboard imply something it hasn’t earned.
