| 1 Prior to 2015, the question asked simply whether the school had "A requirement that visitors sign in." As of 2015, the question has also included the requirement that visitors wear badges or stickers. Data for years prior to 2015 have been omitted because the change in questionnaire wording may affect comparability of the data over time. | ||||||||||||||||||||||||||||||
| NOTE: "At school" includes in the school building, on school property, on a school bus, and, from 2001 onward, going to and from school. Some data have been revised from previously published figures. | ||||||||||||||||||||||||||||||
