(CNN) - A transgender first-grader who was born a boy but identifies as a girl has won the right to use the girls' restroom at her Colorado school.
The Colorado Rights Division ruled in favor of Coy Mathis in her fight against the Fountain-Fort Carson School District.
Coy's parents had taken her case to the commission after the district said she could no longer use the girls' bathroom at Eagleside Elementary.
In issuing its decision, the state's rights division said keeping the ban in place "creates an environment that is objectively and subjectively hostile, intimidating or offensive."
Coy's mother, Kathryn Mathis, said she's thrilled that Coy can return to school and put this behind her.
The first-grader has been home-schooled during the proceedings
"Schools should not discriminate against their students," Mathis said. "All we ever wanted was for Coy's school to treat her the same as other little girls. We are extremely happy that she now will be treated equally."

(CNN) - A Colorado school's ruling over a transgender child has sparked questions that could affect schools all over the country.
Which bathroom should be used by a child who identifies as a different gender from his or her body? Where's the line between accommodation and discrimination? At what point is a child old enough for that to even be an issue?
The case focuses on Coy Mathis, a 6-year-old born with a boy's body. She identifies as a girl, and her family is raising her as a girl.
In kindergarten, she used the girl's bathroom with no problem, the family says. But this year, with Coy in first grade, the principal called to set up a meeting to discuss bathroom use. In advance of the meeting, the family asked what the policies are.
"We were told that there were no written policies and that the options would be for Coy to use the boys' restroom or the staff bathroom or the nurse's bathroom for the sick children, which were both on the opposite end of the building," Coy's father, Jeremy Mathis, said on CNN's "Starting Point" on Thursday.
That "would stigmatize her, having to be the only one having to go to a different bathroom, so we weren't OK with that."
The family contacted the Transgender Legal Defense and Education Fund. When an attorney with that group could not work something out with the school, the group filed a state civil rights complaint on the family's behalf.
In the meantime, Coy is being home schooled - partly because her parents fear bullies may make fun of her.
"The district firmly believes it has acted reasonably and fairly with respect to this issue," the school district's attorney, W. Kelly Dude, said in a written statement. "However, the district believes the appropriate and proper forum for discussing the issues identified in the charge is through the Division of Civil Rights process. The district is preparing a response to the charge which it will submit to the division. Therefore, the district will not comment further on this matter out of respect for the process which the parents have initiated."
The school calls Coy a girl as the family wishes, Dude said.
(CNN) - Just like she did during the first half of the school year, first-grader Coy Mathis wants to use the girls' restroom at her Colorado elementary school. But school officials won't let her.
The reason? Coy is transgendered, born with male sex organs but a child who identifies herself as female.
She dressed as a girl for most of last year. And her passport and state-issued identification recognize her as female.
In December, the Fountain-Fort Carson School District informed Coy's parents that Coy would be barred from using the girls' restrooms at Eagleside Elementary in Fountain after winter break.
She could instead use the boys' bathroom, gender-neutral faculty bathrooms or the nurse's bathroom, the district said.
In making the decision, the district "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," attorney W. Kelly Dude said."However, I'm certain you can appreciate that as Coy grows older and his male genitals develop along with the rest of his body, at least some parents and students are likely to become uncomfortable with his continued use of the girls' restroom."
Coy's parents see it differently.
