The document is a lesson plan for a class on grading and reporting practices presented by Sanaida K. Tago at Mindanao State University. It discusses the objectives of explaining the types of grades/marks and determining their purposes. It then lists and briefly describes 5 common types of grading systems - the traditional letter grade system, pass-fail, checklists of objectives, letters to parents/guardians, and portfolios. It concludes by noting that parent-teacher conferences are mostly used in elementary school and are useful for sharing information but limited as a major report due to time constraints and lack of progress records.
