1) The document discusses common grading-related problems such as grade inflation, which is an increase in average grades assigned to students even with the same achievement levels. It identifies causes of grade inflation such as institutional pressure to retain students and changing grading policies.
2) Some questionable grading practices are also examined, including averaging scores, using zeros, and lowering grades for behavioral issues. Guidelines for appropriate grading emphasize using the most recent, comprehensive evidence related to important learning goals.
3) In conclusion, grade inflation and questionable grading practices can undermine an accurate assessment of student achievement. Appropriate grading priorities should be given to recent, comprehensive evidence aligned with learning objectives.
