Three families are suing Saint Anne Catholic School in Wichita for discrimination because of its "English-only" rule.
Damaging evidence was presented against the school Thursday, as students took the stand.
The students testified that they felt singled out by the school and its principal because they're Hispanic.
Last fall, Saint Anne implemented an English only rule because they wanted to stop bullying and cliques in the school. Some parents and students, however, say the rule is discriminatory.
One child, 12-year-old Dalia Fernandez, testified that she felt said because she wasn't allowed to speak her native language at recess or lunch. She also said that the principal, Sister Margaret, scared her when she pulled her out of class to warn her against speaking Spanish.
The Fernandez family is one of the three families suing the school and the Catholic Diocese of Wichita.
One student did admit she heard another student call someone a name in Spanish.
The Diocese and the school declined comment until after the trial is over.
