Back to school and back to dress coding

Going back to school in August inevitably means that the parenting boards fill up with tales from parents whose children have been pulled from class, made to change, and even punished for violations (or perceived violations) of dress codes.
Last week's Worcester teacher orientation began with a review of the updated dress codes, which, it was quickly noted online, still make no allowance for headwraps not of religious or medical significance.
To add to the resources we have available in this conversation, let me add to Seattle this piece from Phi Delta Kapplan looking at the disparate impacts of dress codes on students of color.
