If we graded schools on how accurately they grade students, they’d fail. Nearly six out of 10 course grades are inaccurate, according to a new study of grades that teachers gave to 22,000 middle and high school students in 2022 and 2023.
The Equitable Grading Project, a nonprofit organization that seeks to change grading practices, compared 33,000 course grades with students’ scores on standardized exams, including Advanced Placement tests and annual state assessments. The organization considered a course grade to be inaccurate if a student’s test score indicated a level of knowledge that was at least a letter grade off from what the teacher had issued. For example, a grade was classified as inaccurate if a student’s test score indicated a C-level of skills and knowledge, but the student received an A or a B in the course. In this example, a D or an F grade would also be inaccurate.
Inflated grades were more common than depressed grades. In this analysis, over 40 percent of the 33,000 grades analyzed – more than 13,000 transcript grades – were higher than they should have been, while only 16 percent or 5,300 grades were lower than they should have been. In other words, two out of five transcript grades indicated that students were more competent in the course than they actually were, while nearly one out of six grades was lower than the student’s true understanding of the course content.

The discrepancy matters, the white paper says, because inaccurate grades make it harder to figure out which students are prepared for advanced coursework or ready for college. With inflated grades, students can be promoted to difficult courses without the foundation or extra help they need to succeed. Depressed grades can discourage a student from pursuing a subject or prompt them to drop out of school altogether.
“This data suggests that hundreds, perhaps thousands, of students in this study may have been denied, or not even offered, opportunities that they were prepared and eligible for,” the white paper said.
This analysis is evidence that widespread grade inflation, which has also been documented by the ACT, the National Center for Education Statistics and independent scholars, has persisted through 2023. In this transcript analysis, grade inflation occurred more frequently for Black and Hispanic students than Asian and white students. It was also more common for low-income students.
Large discrepancies were documented. Almost 4,800 of the inflated grades were two letters higher than the student’s test score would indicate. An AP exam might have indicated a D-level of mastery, but the student earned a B in the class. On the flip side, more than 1,000 students received grades that were two letter grades lower than their assessment score.
The report rejected the possibility that test anxiety is the main culprit for such widespread and large discrepancies, and laid out a list of other reasons for why grades don’t reflect a student’s skills and content mastery. Some teachers feel pressure from parents and school administrators to give high grades. Many teachers factor in participation, behavior and handing in homework assignments – things that have little to do with what a student has learned or knows. Meanwhile, grades can be depressed when teachers make deductions for late work or when students fail to turn in assignments. Group projects that are weighed heavily in the final grade can swing a student’s final transcript grade up or down. In the report, one superintendent described how teachers in his district awarded students points toward their grade based on whether their parents attended Back to School Night.
Reasonable people can debate how much grades should be used to promote good behavior. The Equitable Grading Project argues that schools should use other rewards and consequences, and keep grades tied to academic achievement.
However, solutions aren’t quick or easy. The organization worked with over 260 teachers during the 2022-23 school year to implement a version of “mastery-based grading,” which excludes homework, class assignments and student behavior from the final grade, but uses a range of assessments – not only tests and papers – to ascertain a student’s proficiency. Teachers were encouraged to allow students multiple retakes. After five workshops and four coaching sessions, teachers’ grading accuracy improved by only 3 percentage points, from 37.6 percent of their grades accurately reflecting student proficiency to 40.6 percent.
Part of the challenge may be changing the minds of teachers, who tend to think that their own grades are fine but the problem lies with their colleagues. In a survey of almost 1,200 teachers that accompanied this quantitative study, more than 4 out of 5 teachers agreed or somewhat agreed that their grades accurately reflect student learning and academic readiness. But nearly half of those same teachers doubted the accuracy of grades assigned by other teachers in their own school and department.
Grading practices are an area where schools and teachers could really use some research on what works. I’ll be keeping my eye out for solutions with evidence behind them.
