Racial Disparity Grade
The racial disparity grade was assigned grades based on the following value - any significant racial disparity is failing. In the context of this report card, any racial disparity ratio greater than 1.44 is failing. However, to recognize the significant difference between 1.45 racial disparity ratio and 99.45 racial disparity ratio, failing grades were assigned from 0 to 40. A racial disparity ratio of 1.45 means that the racial group with the highest exclusion rate was 1.45 times more likely to be excluded than other racial groups in the particular school. While a racial disparity ratio of 99.45 means that the racial group with the highest exclusion rate was 99.45 times more likely to be excluded than the other racial groups in the particular school or district.
Three schools earned a grade of 100 because they did not have any racial disparity while another 4.7% earned between 90 to 95 for having less than or equal to 1.44 racial disparity ratio.
On the other hand, 20(2.3%) of the districts earned a "0" for having racial disparity ratio greater than or equal to 99.45.
Most schools (600 or 68.3%) earned a grade of 40 for a racial disparity ratio between 1.45 to 9.44.

(NOTE: For some school districts this is an approximation of the racial disparity ratio since they report enrollment as "less than10" and exclusions as "less than 10". In those circumstances, we used "5" as the enrollment number and "3" as the exclusion number. Please check with your school district for more accurate information)
Community (Charter) Schools had a higher mean grade (40.11) than Public District (36.98). That difference was statistically significant (p=.005). That is, there was less than a .5% probability that the difference occurred by chance alone.
