Academic grades are to reflect the student’s academic progress based on the standards for the grade level/course in which the student is enrolled. The grade must not be based upon the student’s effort and/or conduct. The grade must provide for both students and parents a clear indication of each student’s academic performance as compared with norms which would be appropriate for the grade or subject. As per Florida Statutes § 1003.437, letter grades shall be used to measure student success in grade 6 through grade 12 courses with each letter grade corresponding to a specific percentile from zero to one hundred percent. The academic grades of “A,” “B,” “C,” “D,” or “F,” are not related to the student’s effort, conduct, attendance or tardiness. Grades in all subjects are to be based on the student’s degree of mastery of the instructional objectives and competencies for the subject based on grade level standards. The determination of the specific grade a student receives must be based on the teacher’s best judgment after careful consideration of all aspects of each student’s performance during a grading period.
