This document discusses effective grading practices for K-12 schools. It begins by noting that well-designed classroom assessments can provide specific and timely information to guide learning, unlike external standardized tests. The document then examines common problems with current grading practices, such as inconsistencies, using grades as punishment, and not clearly reflecting students' mastery of course standards. It proposes guidelines for standards-based grading, including basing grades solely on achievement and not including behaviors, avoiding zero scores, providing clear performance standards, and emphasizing more recent assessments. The overall message is that schools should implement grading practices that more accurately communicate what students have learned.
