SAN ANTONIO -- An eighth-grader at a northwest side charter school said she was humiliated by one of her teachers over her religious expression.

Kelsey, a 13-year-old at the School of Science and Technology's Discovery campus, said one of her teachers humiliated her in front of her classmates while repeatedly questioning her religious beliefs because she wore a Catholic rosary.

"She told me to take it off, and I told her no," Kelsey said. "So she took me to the principal's office and he took it away from me, and told me to get it at the end of the day."

Kelsey said she continued to wear the rosary to school only to have the unidentified teacher question her religious beliefs.

"She has this teacher who is picking on her (about) something that's none of her business, and no one will speak to me about it or address the situation," said Marleana Ayala, Kelsey's mother.

School officials refused to speak about the situation, but did release a statement to KSAT 12 News.

"Students have no problem exercising freedom of speech and freedom of religion, as long as they follow the general school's rules and do not interfere with the rights of others," the statement read. The statement did not elaborate on the exact school policy when pertaining to religious items.
