Schools will be allowed to teach the Eddie Eagle Gunsafe Program sponsored by the National Rifle Association and to seek financial grants to do so. The law does not mandate the course.
The NRA said the course has been taught to more than 26 million children nationwide since it began in 1988. Virginia enacted a law in 2010 allowing gun-safety courses based on the NRA program.
The Missouri legislation requires schools to conduct an active-shooter drill led by law enforcement officers.
It also assigns the duty of issuing identification cards for concealed gun permits to sheriffs, instead of driver's license clerks.
