This document provides an overview of a presentation on 15 fixes for broken grades. The presentation is given by Ken O'Connor with assistance from three others. It defines key terms related to grading like marks, scores, and grades. It also discusses the purposes of grading and issues that can make grades broken if they distort achievement, are of low quality, involve inappropriate calculations, or don't support learning. Fifteen specific fixes are proposed to address these issues, and participants are invited to discuss the fixes.
