!Interpret data with caution. The coefficient of variation (CV) for this estimate is between 30 and 50 percent.

‡Reporting standards not met. Either there are too few cases for a reliable estimate or the coefficient of variation (CV) is 50 percent or greater.

1 Access to buildings is controlled during school hours (e.g., by locked or monitored doors).

2 Access to grounds is controlled during school hours (e.g., by locked or monitored gates).

3 All students must pass through a metal detector each day.

4 Examples of contraband include drugs and weapons. The "sweeps" category does not include dog sniffs.

5 Elementary schools have grade 6 or below, with no grade higher than 8; secondary schools have no grade lower than 7; and combined schools have grades lower than 7 and higher than 8.
