Establishing letter grades based on cut scores is the first step in calculating the letter grades presented on the "A-F Grading for Kansas Schools." The second step is to get grade level data for every school and assign each grade level within a school four separate grades based on the average scale score for each of these categories:
- Math results for low-income students
- Math results for all other students
- ELA results for low-income students
- ELA results for all other students
The next step is to calculate an average for those grades based on a four-point scale:
- A – 4 points
- B – 3 points
- C – 2 points
- D – 1 point
- F – 0 points
Finally, that arithmetic average is translated back into one letter grade based on these ranges:
- A – 3.5 to 4.0
- B – 2.50 to 3.49
- C – 1.50 to 2.49
- D – 0.50 to 1.49
- F – Below 0.5
Examples
- A high school (only 10th graders are tested) has the following four results:
9 (total points) / 4 (grades) = 2.3 GPA
Overall school grade – C
- An elementary school (3rd, 4th, 5th grades tested) has the following 12 results:
34 (total points) / 12 (grades) = 2.8 GPA
Overall school grade – B
