As a college student, you already know how much grade point averages matter.

Your GPA determines whether or not you keep your scholarships. It affects your chances of getting into grad school. It could be the tie-breaker when you’re competing for a job.

But grades also matter because they are supposed to reflect what you know and can do.

While everyone wants good grades, it’s generally a bad sign when everyone gets them. If that’s happening, the bar for “excellence” is too low. Some people are getting high grades for doing less, cheapening the value of an “A” so that truly exceptional students don’t stand out.

A recent report, “Easy A’s and What’s Behind Them" by the National Council on Teacher Quality (NCTQ) looks at more than 500 colleges (including Michigan State University) and finds that, on average, about 30 percent of all students at these schools graduate with grade-based honors.

What’s troubling for NCTQ, a research organization that advocates for improving the instruction of K-12 students by improving the preparation of their teachers, is that “Easy A’s” also found that teacher candidates at the schools we reviewed are nearly 50 percent more likely than their peers across campus to graduate with honors.

At Michigan State University, however, there is no worrisome discrepancy between the proportion of teacher candidates who earn honors and other majors. Specifically, 19 percent of soon-to-be teachers at Michigan State University graduate with honors, which compares with 20 percent for all programs on campus.

We hope to see more institutions follow this example. For teacher candidates and all other students, if virtually everyone has stellar grades, an easy A doesn’t really help you get a job, and it definitely won’t help you keep it.
