Carney Curve

Boston College course evaluations · Fall 2021 through Spring 2026, ranked class by class

How this list is ordered

Positions account for how many records stand behind each number, so one perfect review does not outrank a semester of them. Every score shown is the real average — only the ordering is adjusted.

Boston College's ratings are bunched at the top — the median instructor averages about 88 out of 100 on the raw scale, and 44% of them clear 90 — so a raw score cannot separate anybody. Every figure here is ranked against BC instructors and that rank is re-expressed out of 100, which is what turns a raw 88 — the middle of the university — into a figure that says where somebody actually stands. On this scale 77 is the median, 84 the top quarter and 91 the top tenth. Workload is then an adjustment on top of that, worth nothing at all for an ordinary one. Lighter work than 18% of BC instructors.

BC evaluations9125 records · weight ×1.0 · Fall 2021 – Spring 2026

Student reviews—no reviews — not counted
How is this worked out?

Sources are averaged by how much we trust each one and by how many records sit behind it, so a handful of reviews nudges the number rather than replacing it.

Collected from RateMyProfessors, not from Boston College: 13 ratings, 77% would take again, difficulty 62 out of 100. Difficulty is not a quality signal in either direction — a harder course is not a worse one.

Anyone can post there — no @bc.edu check and no enrolment check — so it is weighted alongside the evaluation data, never above it.

Where challenge and workload come from
Challenge
85thMore challenging than 85% of BC instructorsranked against every one we hold
93BC — “Intellectually Challenging”25 records · raw score out of 100

Boston College's own “intellectually challenging” question. It is not a measure of difficulty, grading or workload. Boston College's own “intellectually challenging” question — students answer it positively about courses that stretched them, so it measures intellectual challenge and NOT grading, workload or quality. Almost every BC class scores high on it, which is why it is shown as a rank rather than a score. RateMyProfessors separately rates this instructor 62 out of 100 for difficulty — that IS a difficulty measure, but it is about the person across everything they teach, not about any one class, so it is shown here rather than folded into the number above.

Workload
82ndMore work than 82% of BC instructorsranked against every one we hold
63BC — “Workload”25 records · raw score out of 100

One of Boston College's five workload bands, not a number of hours. Higher means more work, not worse. Boston College reports workload as one of five bands, not as a number of hours, and it does not publish what the bands mean — so this site will not translate it into hours. Higher means more work, which is not the same as worse.

Why these numbers are curved

Both the number and the bar are the rank against every comparable record we hold, printed back out of 100. BC's questions all have a median around 4.5, so on the raw scale every cell here would read in the high eighties and every bar would be nearly full — thirteen numbers that tell you nothing. Each cell prints its raw BC figure and its percentile underneath, so nothing is hidden by the transform. Every bar is one ink colour — nothing here is graded green or red. The hatched bars are not ratings at all: a higher number on either describes a different course, not a better one.

None of the evaluation questions were reported for these records.

How each position is worked out

Positions account for how many records stand behind each number, so one perfect review does not outrank a semester of them. Every score shown is the real average — only the ordering is adjusted.

How to read this page

The big number is a CURVE score, not Boston College's average. BC's own scale is bunched at the top — the median instructor averages about 88 out of 100 on it and 44% of them clear 90 — so this site ranks the average against every instructor we hold and prints that rank back out of 100. A 77 is the median, 84 is the top quarter, 91 is the top tenth. On top of that sits an EASINESS adjustment worth up to about ±6 points — the workload rank turned over, so a lighter class gains and a heavier one loses, while an ordinary workload is worth exactly nothing — and the adjustment is printed on the card, signed. Every raw BC average and every percentile behind the curve is in the strip under the plate, and the thirteen items below are shown the same way, curved, with the raw figure on each cell. Challenge is not difficulty and workload is not hours; neither is marked better or worse. A dash means the question was not reported, and is never a zero. The position printed against each class is this instructor's place on that class's own board, computed from the same records the board itself is built from.
