Students at Mansfield High School are graded on a 0-100 scale, where an A is 90-100, a B is 80-89, a C is 70-79, a D is 65-69, and anything below a 65 is considered failing. Students are awarded credit for each successful passing of a course, however if a student is absent from the course too many times, credits may be deducted.
Class rank is determined by calculating a student’s course-weighed grade point average over an extended 4.0 scale. Rank is calculated once a year, with the rank calculated after a students sixth semester (junior year) being reported to colleges. Valedictorian and Salutatorian are determined by calculating class rank after the completion of a seventh semester.
Rank is calculated by first converting a final grade to the 4.0 scale, then weighting it depending on what level each course taken is at. That average is then multiplied by the number of credits a student earned and then divided by the total number of possible credits for the course. This result is the student's weighted GPA. This process is repeated for each class and then the sum of all class GPAs are averaged to result in an overall GPA. It is possible to get over a 4.0 GPA once weighting of the student's final grade has occurred.
