However its findings are putting and construct the argument in opposition to elevating grades.
College students who skilled extra lenient grading had been much less prone to go subsequent programs, posted decrease check scores afterwards, had been much less prone to graduate from highschool and enroll in faculty, and earned considerably much less years later.
The financial price isn’t small. Denning estimates that when a trainer doles out grades which are considerably larger (0.2 or extra factors on a 4-point scale, the distinction between a B and virtually a B-plus), a pupil in that class loses about $160,000 in lifetime earnings, measured in current {dollars}.
That’s the impact of a single trainer, in a single yr. If a pupil encounters a number of grade-inflating academics, the losses add up.
Proof from two very totally different locations
The researchers examined college students in two settings: Los Angeles and Maryland.
Los Angeles Unified College District offered information on virtually one million highschool college students from 2004 to 2013, a interval when commencement charges hovered simply above 50 p.c. The scholar inhabitants was greater than 70 p.c Hispanic, and failing grades had been frequent.
Maryland’s information adopted about 250,000 highschool college students from 2013 to 2023. Commencement charges exceeded 90 p.c, and the coed inhabitants was extra racially blended. Maryland’s information allowed researchers to trace faculty enrollment, employment and earnings, whereas the Los Angeles information ended with highschool.
Regardless of these variations, the sample was the identical.
College students taught by lenient graders — outlined as academics who gave larger grades than anticipated primarily based on standardized check scores and prior pupil efficiency — did worse later in highschool. In Maryland, the place there was information by way of faculty and into the office, these college students had been additionally much less prone to attend faculty or be employed, and earned much less.
Seeing the identical sample in two very totally different programs strengthens the case that this isn’t a fluke of 1 district or one coverage regime.
When leniency helps and when it doesn’t
The examine makes an important distinction. Academics who nonetheless stored A’s difficult, however solely made it simpler to go — turning failures into low passing grades — did assist extra college students graduate from highschool, notably these prone to dropping out. That short-term profit is actual. For some college students, passing Algebra I as a substitute of failing it might probably maintain them on observe to graduate and presumably enroll in group faculty.
However the profit stops there. These college students don’t present long-term beneficial properties in faculty diploma completion or earnings. The leniency helps them clear a hurdle, however it doesn’t construct the talents they want afterward.
Against this, basic grade inflation (academics who increase grades throughout the board, from C’s to B’s to A’s) exhibits no upside and hurts college students’ probabilities of future success.
Why good intentions backfire
The examine can’t immediately clarify why larger grades result in worse outcomes. However the mechanism isn’t troublesome to think about. In a category with a lenient grader, a savvy pupil could shortly notice she doesn’t want to check arduous or full all of the homework. If she earns a B in Algebra I with out studying how one can issue or resolve quadratic equations, the information gaps observe her into geometry and past. She could scrape by once more. Over time, the deficits compound. Confidence erodes. Studying slows. In faculty or the office, the implications present up as decrease abilities and decrease pay.
As Denning put it in the course of the presentation, there seems to be a “causal chain” of hurt, even when he can’t measure immediately how a lot much less college students are finding out or how behind they’ve fallen.
Don’t rush responsible academics
Elevating grades isn’t all the time a person teacher’s choice. A 2025 survey paperwork the frustrations of many grade-inflating academics who say that they really feel stress from directors to adjust to “equitable grading” insurance policies that forbid zeros, enable limitless retakes and get rid of penalties for late work.
Lenient graders aren’t dangerous academics. The examine finds they’re usually higher at enhancing non-cognitive abilities. Their college students behave higher, cooperate extra, and are much less prone to be suspended. Nonetheless, on this examine, that’s not translating into higher life outcomes, as one would hope.
Stricter graders are typically higher at elevating college students’ check scores in math, studying and different educational topics. Regardless of that correlation, that doesn’t imply all robust graders are good academics. Some aren’t.
That is early analysis. Extra research are wanted to know whether or not there are related office prices from faculty grade inflation. And there are questions on whether or not boys react otherwise than women to inflated grades.
Academics battle to get college students to interact in studying, which is stuffed with setbacks, frustration and boring repetition. Possibly low grades gained’t encourage college students to do that arduous work. However this early proof means that inflated grades aren’t doing them any favors.
