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 classes 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 22% of BC classes.

The class itself, averaged across everyone who taught it — who taught it is the board below.

How is this worked out?

That is what a student picking a section is actually choosing between: the board carries each instructor's own score for this class, and the score above is the class averaged across all of them.

What the challenge rank is made of
37thMore challenging than 37% of BC classesranked against every one we hold
88BC — “Intellectually Challenging”1 record · raw score out of 100

Boston College's own “intellectually challenging” question. It is not a measure of difficulty, grading or workload.

How is this worked out?

Boston College's own “intellectually challenging” question for this class only — 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.

What the workload rank is made of
78thMore work than 78% of BC classesranked against every one we hold
60BC — “Workload”1 record · raw score out of 100

One of Boston College's five workload bands, not a number of hours. Higher means more work, not worse.

How is this worked out?

Boston College reports workload for this class only 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.

There is no ranking to read here: Yajun Mo is the only instructor with evaluation records for HIST 4047, so the number is a record, not a position. It rests on 1 record, which is thin — read it as provisional. The RateMyProfessors figure is their overall score across everything they teach, not their score in this class.

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.

How to read this board

Instructors are ranked on their record in this class only, never on their average across everything they teach. Scores are out of 100 — Boston College's 1–5 agreement scale, ×20, the way these numbers were printed for years. Workload is BC's own five-band figure, not a number of hours, and is shown as a rank. A dash means the question was not reported, and is never a zero.
