In a previous post, I explained competency-based or “mastery” grading: a restructuring of the common grade system that compresses everything from course tests, homework, and class participation into a system that assesses students based entirely on whether or not they’ve mastered specific skills and concepts. (For a look at how mastery grading works in practice, check out how schools like Columbus’s Metro Early College School and Cleveland’s MC²STEM high school, and even suburban districts like Pickerington, make it work). In this piece, I’ll discuss some additional benefits and drawbacks of mastery grading.
Mastery grading is innovative in that students only move on to more complex concepts and skills once they mastered simpler ones. As a result, the failure to master on the first attempt isn’t “failure.” It’s a chance for students to receive additional instruction and support targeted at specific weak spots, work hard, master key concepts, and move on with a firm foundation in place.
For teachers, the possibility of meaningful achievement data that is disaggregated by child and skill and directly drives instruction should be drool-worthy. Imagine knowing at the beginning of the year—before ever giving a diagnostic assessment—what your new students have fully, partially, and not-yet mastered.
To be clear, implementing mastery grading effectively will take a shift in mindsets, habits, and practice, and it will increase the administrative burden at first. Teachers will have to be true masters of their content. They will also be called upon to plan even further in...
