14.3.1.3.5 Grade Value of Core Courses. The following grade values are to be used in determining a student's grade-point average in the core courses: A = 4 quality points, B = 3 quality points, C = 2 quality points, D = 1 quality point. In determining the core-curriculum grade-point average, each grade earned in a course (including all numerical grades) must be converted to this 4.000 scale on an individual-course basis. Pluses or minuses within a grade level shall not receive greater or lesser quality points. A school's normal practice of weighting honors or advanced courses may be used to compute the quality points awarded in those courses and the cumulative grade-point average, provided a written statement verifying the grading policy accompanies the prospective student-athlete's official grade transcript. An honors or advanced course shall receive no greater than 1.000 additional quality point (e.g., A=5.000). In calculating the grade in a weighted honors or advanced course, if a high school does not assign quality points to its courses, quality points shall be added to each course before calculating the student's grade-point average and not added to a student's cumulative core-course grade-point average. The core-curriculum grade-point average may be calculated using the student's 16 best grades from courses that meet the distribution requirements of the core curriculum.
