Under a new policy, students will be able to earn passing grades with scores of just 20 percent — and a solid C for doing absolutely nothing at all.

The lax, taxpayer-funded Cotati-Rohnert Park school district's new grading system is called the equal interval scale, reports The Press Democrat, a newspaper out of nearby Santa Rosa.

The Cotati-Rohnert Park grade scale deviates from the traditional, well-established A-through-F scale by distributing grades in 20-percent increments from 0 to 100 percent, and by only giving grades of F for students with scores below 20 percent.

Thus, students who receive a score of 80 will be awarded an A-. In fact, any grade from 80 to 100 will be either an A or A-. By way of comparison, most students in America who score between 80 and 85 in a given class are sent home with either a B- or a B.
