GPA & Class Rank Committee
School Board Approved Revisions to Policy 6-6.3June 2018
• Discontinued ranking of students by GPA
• Replaced Val/Sal with MCPS Achievement Standards:
Distinguished Scholar: GPA of 4.0 and AboveScholar: GPA of 3.80 - 3.99Honor Graduate: GPA of 3.60 - 3.79
Members of the GPA & Class Rank Committee continued to work on a way to calculate GPA that would award additional grade points for weighted courses but not lower a GPA for taking additional unweighted courses.
MCPS Policy 6-6.3
The student’s grade point average shall be computed to four (4) decimal
places and shall be based on the total number of quality points earned
divided by the total number of credits attempted.
However, if all final grades are equal and the number of weighted
courses completed is equal, no student shall be penalized in the
computation of class rank for completing more classes than other
students. In such cases, to avoid GPA penalties for completing a higher
number of nonweighted classes, the lowest common number of non-
weighted classes among the students with matching final grades and
numbers of weighted courses shall be used in computing class rank.
PRIOR TO 2015:
MCPS Policy 6-6.3
The student’s grade point average shall be computed to four (4) decimal
places and shall be based on the total number of quality points earned
divided by the total number of credits attempted.
However, if all final grades are equal and the number of weighted
courses completed is equal, no student shall be penalized in the
computation of class rank for completing more classes than other
students. In such cases, to avoid GPA penalties for completing a higher
number of nonweighted classes, the lowest common number of non-
weighted classes among the students with matching final grades and
numbers of weighted courses shall be used in computing class rank.
APPROVED 2015:
When a student takes unweighted electives in addition to weighted AP and/or DE classes, that student’s GPA will be lower than a student’s GPA who took a study hall.
Why Change GPA Calculation?
Student X Student Y
A = 5A = 5A = 5A = 5A = 4A = 4A = 4A = 4A = 4A = 4----------------44/10 = 4.4000 GPA
A = 5A = 5A = 5A = 5A = 4A = 4A = 4A = 4A = 4A = 4A = 4----------------48/11 = 4.3636 GPA
Decisions made based solely on GPA:
• Dropping “unweighted” A’s earned in Middle School• Deciding not to continue in a Fine Arts or CTE program that they love• Forgoing a Work-Based Learning or Research Project opportunity • Taking external courses at local colleges/universities• Overloading AP and/or DE courses

Reframing the Problem
• The more total credits a student attempts, the less the additional grade points for weighted courses are worth.
• As a result, limiting the number of credits a student attempts will raise his/her GPA.
What’s Causing the Problem?
• We are awarding the additional grade points for weighted courses prior to dividing by the total number of credits attempted.
• The total number of credits attempted varies from student to student.
Each student actually gets a different amount added to his/her GPA for earning the same grade in the same course
A=5 A=5 A=5 A=5
GPA = 4.045
21 Unweighted A’s
1 Weighted A25 Unweighted A’s
1 Weighted A
31 Unweighted A’s
1 Weighted A
35 Unweighted A’s
1 Weighted A
GPA = 4.031 GPA = 4.027GPA = 4.038
What’s Causing the Problem?
Because the additional grade point earned is divided by a different number of total credits attempted
AP CHEMISTRY
The Solution
• First calculate EVERYONE’S GPA on a 4-point scale.
• Use the same denominator (32) for all students to determine the additional grade points for weighted classes.
• Then add those grade points to get Final GPA.
Each student gets a the same amount added to his/her GPA for earning the same grade in the same course
A=5 A=5 A=5 A=5
GPA = 4.031
21 Unweighted A’s
1 Weighted A25 Unweighted A’s
1 Weighted A
31 Unweighted A’s
1 Weighted A
35 Unweighted A’s
1 Weighted A
GPA = 4.031 GPA = 4.031GPA = 4.031
The Solution
Because the additional grade point earned is divided by the same number (32) for everyone
AP CHEMISTRY
The Impact
• Every additional grade point for a weighted class will be worth the same amount for every student.
• Students with the same grades and the same number of weighted credits will always have the same GPA.
• There is no incentive to limit the number of unweightedcredits. Limiting the number of credits attempted will no longer raise a student’s GPA.
• Allows all students to be compared to the same achievement standard, regardless of the number of credits attempted.
Why Divide by 32?
• Matches our standard high school course load(4 years x 8 credits per year = 32 credits)
• Comparable to using a 5-point scale (A=5)
• Produces very similar GPAs to our current system
The Effect
Examined the impact of using the proposed GPA Calculation method on 2,111 actual MCPS students (Graduating Classes of 2016, 2017, and 2018):
• Average GPA stayed the same (3.18)
• Average change in GPA was very small (0.0009)
• 48% of students’ GPAs were unchanged
Proposed MethodStudent X = (33x4) / 33 = 4.0 + 0.34 = 4.34 Student Y = (35x4) / 35 = 4.0 + 0.34 = 4.34
Student X = (11x5) + (22x4) / 33 = 4.3333 Student Y = (11x5) + (24x4) / 35 = 4.3142
Current Method
1. Calculate EVERYONE’S GPA first on a 4-Point Scale2. Add Grade Points to that GPA for weighted classes (comparable to A = 5):
11 weighted credits = 11 additional grade points11 ÷ 32 = 0.34
PROPOSED CHANGES TO POLICY 6-6.3
Calculating Grade Point Average (GPA)
MCPS will calculate Grade Point Average (GPA) for each high school student using a four-point system for all high school credit courses (A=4, B=3, C=2, D=1, F=0). The number of credits earned for each course will be multiplied by the numerical value of the final course grade to obtain the number of grade points earned for each course. The total grade points earned will be divided by the total credits attempted to determine each student’s GPA (calculated to two decimal places, with no rounding).
Additional Grade Points for Advanced CoursesFor each passing grade earned in an advanced course (Advanced Placement, Dual Enrollment, and approved courses taken at an accredited college/university), students will be awarded one additional grade point. The total additional grade points will be divided by 32, and the result will be added to the GPA. The resulting GPA will be comparable to a “weighted GPA” using a five-point system (A=5, B=4, C=3, D=2, F=0). The final GPA will be calculated to two decimal places, with no rounding.
Examples
PROPOSED CHANGES TO POLICY 6-6.3
If a student attempted 32 credits that did not include any advanced courses, then the student’s GPA would be would be calculated as follows:
If this same student’s coursework included passing 8 advanced courses, then the student would be awarded 8 additional grade points. The final GPA would calculated as follows:
Grade point averages are computed by using final grades for ninth, tenth, eleventh, and twelfth grade classes.Grades earned in high school credit courses taken prior to ninth grade will be included in the computation of grade point averages.
GPA (without additional grade points) 3.90
Additional Grade Points Earned 8
GPA Increase (8 ÷ 32) 0.25
Final GPA (3.90 + 0.25) 4.15

The Impact
• Every additional grade point for a weighted class will be worth the same amount for every student.
• Students with the same grades and the same number of weighted credits will always have the same GPA.
• There is no incentive to limit the number of unweightedcredits. Limiting the number of credits attempted will no longer raise a student’s GPA.
• Allows all students to be compared to the same achievement standard, regardless of the number of credits attempted.
Recommendations from GPA & Class Rank CommitteeOctober 18, 2018
• Provide information for students/parents on MCPS webpage after first reading to School Board.
• Begin implementation begin with current juniors, sophomores, and freshmen.
• Include GPA Calculation in Curriculum Information Nights for students/parents.
