At the time, Coy's school district said, it had "acted reasonably and fairly with respect to this issue," it said. "However [it] believes the appropriate and proper forum for discussing the issues identified in the charge is through the Division of Civil Rights process."
In December the school lawyers sent a letter to TLDEF that said: "The district's decision took into account not only Coy but other students in the building, their parents, and the future impact a boy with male genitals using a girls' bathroom would have as Coy grew older."
While other students and teachers do not notice that Coy has male genitals, the school said it feared as the child developed parents and students would become "uncomfortable."
"...It would be far more psychologically damaging and disruptive for the issue to arise at an age when students deal with social issues," the letter said.

The 2011 survey, "Injustice at Every Turn," found that discrimination is pervasive in "nearly every system and institution."
