"It is well settled that a public school teacher may not lead, direct or ask her students to engage in prayer," the Foundation's letter said. "The Supreme Court has continually struck down formal and teacher- or schoolled prayer in public schools."The Hondo Independent School District's official policy also prohibits staff from encouraging students to either pray or refrain from praying in school. The school's principal responded within a week of getting the Foundation's letter to say she had met with [Tina Mumme] to remind her of the prayer prohibition. "She understands and will follow correct policy," wrote Principal Ellen Schueling.
