As with everything on this little site, this is a work in progress.
K-12 schools in Alabama just happen, happen, to be strongly divided racially. Not completely (there are some legacy effects of the desegregation period, after all), but, with the intersection of class and cost of housing, pretty thoroughly.
I’ll expand the explanation as to why, a little later, when I have time. Until then, I refer to you to Colby Tanner’s “Some of My Best Friends Are Black”.
If you are choosing a school for your child, or wish to get a good understanding of how school funds are spent in Alabama, or find school performance results for a specific school, I recommend starting at the Alabama School Connection. This excellent resource, pulls together information about education in the state that is otherwise scattered and hard to find.
