Nearly 82 percent said they had been harassed at school in the past year because of their sexual orientation, and nearly 64 percent said they felt unsafe. Almost 30 percent said they had skipped a day of school in the last month because of safety concerns.
Transgender students experienced more hostile school climates than their gay and lesbian peers -- 80 percent reported feeling unsafe at school because of their gender expression.

Stein, who is active in state and national LGBT initiatives and hopes to study economics and politics in college, said she, too, feels "definitely hopeful."
"I have noticed a shift even in the last couple of years," she said. "In the eighth and ninth grades, I was very depressed. My high school culture has shifted for me and has come to terms with my identity. Student attitudes have also changed. Now, they don't just tolerate me, but a majority accept me as I am."
Chase said even though she has "tons of friends," she still hears the words "dyke" and "faggot" daily at school. But more often than not, when she calls attention to their language, students respond, "I'm sorry I offended you. ... It was my mistake."
"They understand," she said.
