| 1 Before 1999, Asian students and Pacific Islander students were not categorized separately, and students could not be classified as Two or more races. Because the response categories changed in 1999, caution should be used in comparing data on race from 1993, 1995, and 1997 with data from later years. | |||||||||||||||||||||||||||||||||||
| 2 Students were asked which sexual orientation--"heterosexual (straight)," "gay or lesbian," "bisexual," or “not sure"--best described them. | |||||||||||||||||||||||||||||||||||
| NOTE: Survey respondents were asked about being threatened or injured "with a weapon such as a gun, knife, or club on school property." "On school property" was not defined for respondents. Race categories exclude persons of Hispanic ethnicity. | |||||||||||||||||||||||||||||||||||
