How to Calculate a Report Card Grade

A grading scale refers to the system that a teacher will use to convert student numerical scores into letter grades. Traditionally, the grading scale ranges from A for top performing students to F for the lowest performing. Each letter grade is usually accompanied by a percentage that indicates how many questions you answered correctly on an exam or assignment. While there are variations for grading scales that account for plusses or minuses (A+ or A-, etc.), the most common grading scale is:

• A = 90-100 Percent
• B = 80-89 Percent
• C = 70-79 Percent
• D = 60-69 Percent
• F = 59 Percent and below

In an unweighted system, grades have point values, and you find the final grade with how many points you earned out of the total possible points. A point is a point and no one point has more value than another, even though some assignments may be worth more overall points than others. A teacher may assign homework to be worth 10 points per assignment and tests to be worth 15 points each, or all assignments may be worth the same number of points. Point distribution is at the discretion of the teacher, so check your syllabus for information on how the teacher has set this up. The course will have a total point value, and your letter grade will come from the number of points you earn out of the total possible points.

Weighted grades take the type of assignment into consideration so that some are worth a higher value than others. The teacher creates categories for grading and assigns a percentage value to each with all categories adding up to 100 percent. Homework, for example, might be worth 10 percent of the class grade, tests and quizzes worth 30 percent, classwork worth 50 percent and participation worth 10 percent. In a set up like this, homework will always amount to 10 percent of the grade no matter how many homework assignments you get and the same goes for every other category. Check your course syllabus for information on which categories the teacher has created and how much weight each carries.
