Some teachers practicing zero intolerance

Some teachers, aware of the devastating effects that one zero can have on a student’s final grade and recognizing the string of perfect scores necessary to negate it, have simply stopped logging zeros. Instead, at some schools, the lowest score students can receive is as high as 50 or 60 – even if they don’t turn in assignments.
The practice challenges a long-held philosophy that if you don’t do the work, you don’t get the grade.
