In our previous system (Education Edge), our 4.0 GPA scale was calculated by averaging the numeric score for each class and converting the average to a 4.0 equivalent. Here is an example:

EngIII American Lit	84
EngIII American Lit	83
Physics	81
Physics	75
Spanish 400	82
Spanish 400	76
Trig. & Analysis	94
Trig. & Analysis	90
US History	83
US History Sum	78 826

 

Sum / Total # of Classes = Numeric GPA

826 / 10 = Numeric GPA

82.6 = Numeric GPA

 

The 82.6 numeric GPA was then translated to a 4.0 equivalent, or a 3.35.

 

In onRecord, each course is converted to a 4.0 equivalent, then averaged:

EngIII American Lit	84	3.69
EngIII American Lit	83	3.15
Physics	81	3.00
Physics	75	3.82
Spanish 400	82	3.22
Spanish 400	76	3.29
Trig. & Analysis	94	3.69
Trig. & Analysis	90	3.29
US History	83	3.36
US History Sum	78	3.29 33.80

 

Sum / Total # of Classes = GPA

33.80 / 10 = GPA

3.38 = GPA (4.0 scale)

 

As you can see, there is a difference in the Education Edge method (3.35) and the onRecord method (3.38).

 

I have noted that the new method has a ± 0.03 effect on a GPA. 

 

Ideally, we would have the option to calculate 4.0 scale GPA by adding up the numeric scores for each class, divide by total number of classes, then converting to 4.0 equivalent.
