A-F grading formula

The state Board of Education approved rule changes that affect the way grades are calculated with the A-F school valuation formula. Grades are figured using a complex, lengthy formula that factors in everything from graduation rates to ACT scores to reading success. Here are some of the changes:

Old rule

Schools received credit for the number of students taking advanced classes. Each student was counted once, regardless of how many honors classes taken.

Schools could earn bonus points for community involvement, college-track classes, low college remediation rates, advanced classes in elementary schools and conducting the Oklahoma School Climate Survey.

The state Education Department released data associated with calculating the grades, and school district officials had 30 days to make corrections.

A-F grades were determined using a 4.0 scale.

The minimum number of students used to calculate the A-F grade was 30. About 700 school sites didn't have enough to meet the threshold.

State testing lumped students into four categories: two passing and two failing. Students received credit for scoring in the top three categories.
