I heard from NPR radio Thursday night about Fairfax public school teacher hiring issue (https://www.washingtonpost.com/local/education/black-teacher-applicants-face-discrimination-in-a-wealthy-school-district-study-finds/2017/05/04/ea192b50-2a90-11e7-a616-d7c8a68c1a66_story.html?utm_term=.832126065eb3).
This radio program prompted me to go back to look at HCPSS school staff number by race. This does not imply anything wrong at HCPSS.
Number and Percentage of Certified, Management and Technical Staff by Race
Race and Ethnicity of School-based Administrators by Level and Position
Number of Employees by Race and Ethnicity
The original document is attached here
It is pretty easy to get the above graph from the original data.
