Carney Curve

Boston College course evaluations · every published number, ranked class by class

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.

What the overall is made of
83BC evaluations15 records · weight ×1.0 · Spring 2022 – Spring 2026
Student reviewsno reviews — does not contribute
RateMyProfessorsno ratings — does not contribute

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.

What the challenge rank is made of
78thMore challenging than 78% of BC instructorsranked against every one we hold
92BC — “Intellectually Challenging”15 records · raw score out of 100

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.

What the workload rank is made of
84thMore work than 84% of BC instructorsranked against every one we hold
64BC — “Workload”15 records · raw score out of 100

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.

Bar length is the rank against every comparable record we hold, not the raw score: BC's questions all have a median around 4.5, so a raw-scale bar would be nearly full on every row and would tell you nothing. 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 pageScores are out of 100 — Boston College's 1–5 agreement scale, ×20, the way these numbers were printed for years. Almost every class scores high on that scale (the median is about 90), so challenge and workload are shown as a rank against every instructor we hold rather than as a score; the raw figure is in the breakdown above. Neither describes quality, and neither is ever marked better or worse anywhere on this site. 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.
