At one Carroll County high school, the teachers are telling students who take certain courses that getting a "D" isn't good enough. Those who don't do "C" work fail the course, but the help they get to pass sounds a great deal like the concept behind Washington County School Superintendent Wayne Gersen's "mastery learning" program.
North Carroll's No-D program began as a pilot program three years ago under the leadership of Gregory Eckles, then the school's principal. Eckles said the old grading system is fine if your object is to separate those who naturally achieve from those who don't. But if the idea is to get everyone to achieve at a satisfactory level or better, then you've got to set a standard that students must achieve. This means that those who don't do C-level work (or better) must participate in after-school remedial clinics and undergo retesting to bring up their grades.
