The presentation is Rachel’s Challenge, an educational program established by Darrell Scott. His daughter, Rachel Scott, was the first person killed at Columbine High School on April 20, 1999, in Colorado.

Rachel’s brother, Craig, was in the library that day and lost two close friends and narrowly escaped death himself.

During the school day Thursday, Tonganoxie students in grades 7-12 will attend a program and partake in a training session.

In 2005, Rachel’s Challenger was awarded the Friends of Education award from the state of New York. According to a Rachel’s Challenge press release, the school program has prevented numerous suicides, drastically reduced bullying and in three known cases prevented a planned school shooting.
