* Letter Grades: This is the most prevalent system, typically using a scale like A, B, C, D, and F, sometimes with pluses and minuses (e.g., A+, A, A-, B+, etc.). The specific numerical equivalent for each letter grade can vary.
* Number Grades: Some schools use a purely numerical system (e.g., 90-100 = A, 80-89 = B, etc.). Again, the cutoffs can vary.
* Percentage Grades: A percentage grade directly reflects the student's score out of the total possible points.
* Pass/Fail: While less common for overall grades, some schools might use a pass/fail system for individual assignments or projects.
* Standards-Based Grading: This is a newer approach that focuses on demonstrating mastery of specific learning objectives rather than solely on points or percentages. Grades might reflect the level of proficiency achieved in each area.
To know the specific grading system used at a particular middle school, you need to check the school's website, student handbook, or contact the school administration directly.
