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 – O 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:
1. A high school (only 10thgraders are tested) has the following four results:

9 (total points)/4 (grades)= 2.3 GPA            Overall school grade – C

2. An elementary school (3rd, 4th, 5thgrades tested) has the following 12 results

34 (total points)/12 (grades) = 2.8 GPA                Overall school grade – B
