The table above shows the types of GPA calculations made by STAR system. The table below shows STAR System credit summaries.  The tables also list where the metrics appear on STAR System report cards (R) and transcripts (T).  Some computations are performed for the benefit of users and are not published on documents (N).

In STAR System, a term at a college or in a technical program can be a semester, quarter or any similar division of the academic calendar.  For high schools, a term is one of four periods during the school year.  The first two comprise the first half of the year and the last two comprise the second half.

If you're not familiar with GPA, the following will help you understand how it is arrived at.

1- Total the attempted credits
This is the sum of the credits (or credit hours) for all the courses attempted.  Include
any failed courses, but leave out audited, incomplete or withdrawn courses.

2- If the grade given is a letter, convert the grade to its numerical value
For example, on a four point grade scale, A equals 4, B equals 3, etc.

3- Calculate the credit weighted grade (CWG) for each attempted course
Multiply the numerical grade in each course by the number of credits awarded.

4- Total the credit weighted grades
Add CWG for all courses attempted.

5- Calculate GPA
Divide total CWG by total attempted credits.

Grade scales vary widely from school to school and place to place.  STAR System is designed to work equally well with virtually any grading scheme.

In STAR System a distinction is made between "discrete" and "continuous" grading:

• Discrete grading  The grade assigned by an instructor is a letter (or a combination of letter and number) that needs to be converted to a numeric scale in order to be averaged with other grades.  For example, "A"

• Continuous grading  The grade assigned by an instructor is a number that does not need to be converted in order to be averaged with other grades.  For example, "86"

When setting up STAR System for your school, choose either discrete or continuous based on the grading system you use.

In either case you can display equivalents in the grade scale section of your STAR System report cards and transcripts.  If you assign number grades you can display their letter equivalents.  For example, you can show that 97-100 is A+.  Conversely, if you assign letter grades you can display their numeric equivalents.  For example, an A+ is 97-100.

In STAR System, you can base your grade scale on any non-negative 1, 2 or 3 digit numbers.  Your scale can include ranges (for example, A = 90 to 100) or it can be set to specific numbers (for example, A = 4).

You can make up to 15 grade distinctions (for example, A+, A and A- equal 3 grade distinctions).

The table below shows common grade scales and the recommended choice in STAR System.
